00:00:00.299 hi folks mr. Test Lonnie in here what 00:00:02.27000:00:02.280 we're gonna do today is build a gasifier 00:00:03.64900:00:03.659 unit for a friend of mine that lives in 00:00:05.30000:00:05.310 a tiny house he's asked me for a 00:00:07.19000:00:07.200 gasifying system that'll function to 00:00:09.04900:00:09.059 produce wood gas for his cooking stove 00:00:11.27000:00:11.280 for his lanterns and as well as for 00:00:13.28000:00:13.290 running his generator so I asked for 00:00:15.02000:00:15.030 some material to build the project and I 00:00:16.73000:00:16.740 have got now a couple propane tanks to 00:00:18.71000:00:18.720 do it with I'm using the old trompe 00:00:20.84000:00:20.850 hammer the original trompe amber tank 00:00:22.82000:00:22.830 I've got much better designs now so 00:00:24.71000:00:24.720 we're going to go ahead and cut that 00:00:25.60900:00:25.619 thing up and use it for this gasifier 00:00:27.32000:00:27.330 we've got some old sheet steel there I 00:00:29.59900:00:29.609 think that was a giant square d box 00:00:31.60900:00:31.619 cover for a nickel as a school or 00:00:33.79900:00:33.809 something so we're going to use the 00:00:35.36000:00:35.370 scrap metal here we're going to put 00:00:36.50000:00:36.510 together a nice downdraft style gasifier 00:00:38.63000:00:38.640 so the first part of this is going to be 00:00:40.88000:00:40.890 removing these tops that you see here 00:00:43.63900:00:43.649 the handles and I've already cut them 00:00:45.59000:00:45.600 off of two of them so we're going to go 00:00:47.38900:00:47.399 ahead and pop those off that way you can 00:00:49.34000:00:49.350 see that part of the propane tank the 00:00:50.93000:00:50.940 next part of this obviously is going to 00:00:52.40000:00:52.410 unthread your valve here now if you've 00:00:54.95000:00:54.960 never taken apart or cut into a propane 00:00:56.86900:00:56.879 tank I actually don't suggest that you 00:00:58.49000:00:58.500 ever do it alright so the first step 00:01:01.04000:01:01.050 that this is going to be to get the two 00:01:02.75000:01:02.760 big tanks that you see here we're going 00:01:04.52000:01:04.530 to put those together and make a nice 00:01:06.02000:01:06.030 tall tank out of it you couldn't find me 00:01:07.96900:01:07.979 in the tall tanks we're going to make 00:01:09.28900:01:09.299 one out of the two shorter tanks so 00:01:11.35900:01:11.369 obviously the way to do that just come 00:01:13.21900:01:13.229 down to cut two of the tanks here this 00:01:14.96000:01:14.970 one right here we're going to cut this 00:01:17.06000:01:17.070 one right here we're going to go ahead 00:01:18.53000:01:18.540 and flip this tank over on the cut weld 00:01:20.84000:01:20.850 that back together then we'll go into 00:01:22.70000:01:22.710 the other side of one of the sides here 00:01:24.28900:01:24.299 cut our opening to feed and then the 00:01:26.12000:01:26.130 other one will cut our opening that will 00:01:27.53000:01:27.540 go into the reduction zone into our burn 00:01:29.99000:01:30.000 chamber so let me go ahead and start 00:01:31.70000:01:31.710 this out by cutting the two of these and 00:01:33.49900:01:33.509 getting those welded together and I'll 00:01:34.94000:01:34.950 show you what it looks like so as you 00:01:37.34000:01:37.350 can tell here I've cut the tops off of 00:01:38.81000:01:38.820 both of those propane tanks you can see 00:01:40.76000:01:40.770 that a little bit different size you can 00:01:42.26000:01:42.270 see this one's a little bit smaller than 00:01:43.58000:01:43.590 that one and that allows me not to have 00:01:45.46900:01:45.479 such a perfect cut around my rims I'm 00:01:47.56900:01:47.579 not trying to marry together two perfect 00:01:49.58000:01:49.590 cuts right there rim to rim what I have 00:01:51.74000:01:51.750 here is a little bit of a bevel in here 00:01:53.33000:01:53.340 from the curvature and this one's right 00:01:55.13000:01:55.140 at the flare out so this one will 00:01:56.45000:01:56.460 overlap this just slightly giving me a 00:01:58.81900:01:58.829 nice even edge all the way around then 00:02:00.49900:02:00.509 it can weld without a bunch of grinding 00:02:01.76000:02:01.770 the next step here is to flip that 00:02:03.95000:02:03.960 upside down right on top of there I'll 00:02:05.56900:02:05.579 show you what that looks like and then 00:02:06.64900:02:06.659 we're going to make a lid out of this 00:02:07.70000:02:07.710 piece so I have them now stacked on top 00:02:10.13000:02:10.140 of each other I have the top from the 00:02:12.14000:02:12.150 lower one up on 00:02:13.29000:02:13.300 here just to show you what it's going to 00:02:14.58000:02:14.590 look like as a lid so now I need to cut 00:02:17.10000:02:17.110 a hole inside of that one smaller in 00:02:19.26000:02:19.270 diameter obviously than the lid so the 00:02:20.79000:02:20.800 lid can sit nicely over that and give us 00:02:22.71000:02:22.720 a good seal we'll put a hinge and a 00:02:24.54000:02:24.550 spring on that I'll show you what that 00:02:25.86000:02:25.870 looks like so I got to weld the two of 00:02:27.81000:02:27.820 them together around the center and then 00:02:29.16000:02:29.170 I've also got to cut a hole in the 00:02:30.24000:02:30.250 bottom and that will be where our 00:02:32.19000:02:32.200 concentration point our reduction point 00:02:34.17000:02:34.180 will be so let me get that done I'll 00:02:35.82000:02:35.830 show you what it looks like so I just 00:02:37.83000:02:37.840 showed you the two takes sitting on top 00:02:39.63000:02:39.640 of each other with the other sides cut 00:02:41.25000:02:41.260 out so they're making one large tank 00:02:43.35000:02:43.360 right now both of those tanks flipped 00:02:45.30000:02:45.310 upside down I have the other cuts made 00:02:47.22000:02:47.230 this piece that you see right here is 00:02:49.68000:02:49.690 from the original square D box cover 00:02:52.41000:02:52.420 I've measured a 5 inch wide piece I've 00:02:54.60000:02:54.610 rolled it in a circle so what I did is I 00:02:56.34000:02:56.350 use the original ring that's no longer 00:02:57.84000:02:57.850 welded on there 00:02:58.80000:02:58.810 that was the bottom of the propane tank 00:03:00.93000:03:00.940 as kind of a template for my size of 00:03:02.91000:03:02.920 what I was going to do for a circle 00:03:04.80000:03:04.810 there like I said that's five inches 00:03:06.63000:03:06.640 wide from there to there and I'm now 00:03:08.49000:03:08.500 going to weld that on the hole I cut 00:03:10.77000:03:10.780 into the bottom of that propane tank 00:03:12.51000:03:12.520 just like this or so and we're going to 00:03:15.15000:03:15.160 use that for the reduction zone for a 00:03:16.86000:03:16.870 gasifier one of the things I noticed is 00:03:19.20000:03:19.210 this piece right here one of my cutouts 00:03:20.88000:03:20.890 is probably going to be the exact right 00:03:23.19000:03:23.200 size to sit in there for the screen end 00:03:25.44000:03:25.450 looks like it's going to fit just 00:03:27.09000:03:27.100 perfectly so I'll probably end up using 00:03:28.89000:03:28.900 that for the shaker screen in the bottom 00:03:30.77000:03:30.780 let me go ahead now get this thing set 00:03:33.24000:03:33.250 up I'm going to go and remove this 00:03:35.37000:03:35.380 caller that you see those the original 00:03:37.08000:03:37.090 propane rings it's going to be welded to 00:03:39.33000:03:39.340 one side this caller is going to be well 00:03:40.95000:03:40.960 to the other side we're going to be able 00:03:42.72000:03:42.730 to slide the two into each other and 00:03:44.43000:03:44.440 create kind of a seal between it I'll 00:03:45.99000:03:46.000 show you that when I get that done so 00:03:48.84000:03:48.850 we've got over here is the top of this 00:03:51.09000:03:51.100 propane tank that I cut off underneath 00:03:53.40000:03:53.410 that I've cut a hole now in there and 00:03:55.17000:03:55.180 that's going to be the feed area that's 00:03:57.12000:03:57.130 where we're going to drop all the new 00:03:58.14000:03:58.150 wood in we're going to use this as a lid 00:04:00.36000:04:00.370 off to build a hinge for that and the 00:04:02.22000:04:02.230 way that cup comes up underneath there 00:04:04.11000:04:04.120 and the way this is domed it gives me a 00:04:05.55000:04:05.560 really nice seal so it should be able to 00:04:07.38000:04:07.390 seal down with a spring and a lateral 00:04:09.24000:04:09.250 well so there you go that would be our 00:04:11.22000:04:11.230 little just be able to open shut right 00:04:12.90000:04:12.910 there alright so I just showed you those 00:04:15.27000:04:15.280 pieces real quickly here we grab that 00:04:17.19000:04:17.200 piece we're gonna flip it around I'll 00:04:20.52000:04:20.530 show you it's gonna sit 00:04:21.83000:04:21.840 just like that and that's going to drop 00:04:25.04000:04:25.050 all the way down inside of that lower 00:04:26.68900:04:26.699 spot it's a little hard to get back out 00:04:28.31000:04:28.320 of there without somebody's help our 00:04:30.80000:04:30.810 final piece here for the gasifier is 00:04:32.60000:04:32.610 done I just got done showing you those 00:04:33.95000:04:33.960 two pieces now I've got the lowest ash 00:04:36.37900:04:36.389 bin basically where the ash is going to 00:04:38.15000:04:38.160 get caught as well as all the gases are 00:04:39.95000:04:39.960 going to actually be drawn out of the 00:04:41.27000:04:41.280 system down here from this lower propane 00:04:43.43000:04:43.440 tank and that's a five gallon propane 00:04:44.81000:04:44.820 tank I've cut the top of it out as you 00:04:47.12000:04:47.130 can see here that was the exact same 00:04:49.15900:04:49.169 size is the bottom collar for this ring 00:04:52.28000:04:52.290 and I'll show you just in a moment here 00:04:53.57000:04:53.580 I'll lift that up and slide it down 00:04:55.46000:04:55.470 inside this collar the collar itself 00:04:57.50000:04:57.510 right here that you see was the old ring 00:04:59.42000:04:59.430 that was on the bottom of the propane 00:05:00.74000:05:00.750 tank the stabilization ring that put on 00:05:02.96000:05:02.970 the bottom I've made everything so that 00:05:04.87900:05:04.889 it fits really nice together so that way 00:05:06.89000:05:06.900 you can pull the inner chamber out of 00:05:09.44000:05:09.450 this bottom ash catch to be able to dump 00:05:11.24000:05:11.250 the ash catch out and keep using it over 00:05:13.90900:05:13.919 and over again so I've just completed 00:05:17.36000:05:17.370 our screen for the project and I used 00:05:18.86000:05:18.870 one of the cutouts from when the propane 00:05:20.33000:05:20.340 tanks a twenty millimeter hole saw and 00:05:22.85000:05:22.860 you can see I just made a pattern across 00:05:24.74000:05:24.750 there and drilled out the holes left a 00:05:26.77900:05:26.789 pretty good amount of spacing a material 00:05:28.55000:05:28.560 in between each one of the holes you 00:05:29.75000:05:29.760 don't want it too thin we're now going 00:05:31.43000:05:31.440 to mount this inside of our gasifiers 00:05:33.32000:05:33.330 lower reduction zone we're gonna try to 00:05:35.84000:05:35.850 make a way to shake it as well here we 00:05:38.08900:05:38.099 are looking down at the very bottom of 00:05:40.58000:05:40.590 that reduction chamber I've got the 00:05:42.32000:05:42.330 screen in place now everything's done 00:05:44.56000:05:44.570 kind of walk you up and show you that 00:05:46.64000:05:46.650 I've got a hinge right here there's some 00:05:49.15900:05:49.169 bars going across right here that are 00:05:50.77900:05:50.789 giving a kind of reinforcement on the 00:05:52.61000:05:52.620 bottom of the screen you can see a 00:05:54.26000:05:54.270 washer here with the end of the cable 00:05:55.76000:05:55.770 which I'll show you in a moment our pins 00:05:57.62000:05:57.630 there this is our bottom of the 00:05:59.75000:05:59.760 reduction zone once again and that gives 00:06:01.49000:06:01.500 us the ability to open it up you can see 00:06:04.37000:06:04.380 a cable going all the way up through the 00:06:05.96000:06:05.970 reactor there and I'll show you the end 00:06:07.61000:06:07.620 loop is right there by that steel piece 00:06:09.68000:06:09.690 there kind of a pigtail loop that gives 00:06:11.93000:06:11.940 us stability so we can shake the screen 00:06:13.96900:06:13.979 if it plugs up with ash or material we 00:06:16.46000:06:16.470 can sit there and give it a shake from 00:06:17.77900:06:17.789 the top that make sure it runs real well 00:06:19.96900:06:19.979 something's go up here real quick show 00:06:22.52000:06:22.530 you the little pull on that so here's 00:06:25.31000:06:25.320 the other side of it 00:06:26.39000:06:26.400 if I pull it it shuts the screen down 00:06:28.82000:06:28.830 just like that when you do pull it it 00:06:31.21900:06:31.229 sits down I'll have a hook right about 00:06:34.01000:06:34.020 right there that'll hold it 00:06:35.54000:06:35.550 holds the screen up once you've pulled 00:06:37.25000:06:37.260 it that gives us the ability with the 00:06:39.77000:06:39.780 wood mass on the screen to give it a 00:06:41.48000:06:41.490 shake by just going like this we'll pull 00:06:43.55000:06:43.560 it back up hook it up on the hook and 00:06:45.29000:06:45.300 now it holds the mass back on the screen 00:06:47.33000:06:47.340 again I've got all the pressure relief 00:06:49.76000:06:49.770 system and the mounts and everything 00:06:51.62000:06:51.630 ready for the lids kind of hard to show 00:06:53.09000:06:53.100 you at this angle so let me go ahead and 00:06:57.32000:06:57.330 finish my welds up we'll get that thing 00:06:59.42000:06:59.430 set down inside of the lower container 00:07:01.31000:07:01.320 like I said and I'll show you what the 00:07:03.17000:07:03.180 lid looks like and we'll get it fired up 00:07:04.97000:07:04.980 somewhere in the filming I lost the film 00:07:07.01000:07:07.020 of the lids construction so I thought 00:07:09.17000:07:09.180 I'd do a real quick ad in here first of 00:07:11.96000:07:11.970 all I just welded some little loops off 00:07:13.61000:07:13.620 of the lid you can see right here that 00:07:14.99000:07:15.000 little loop this little steel loop here 00:07:17.90000:07:17.910 I've got Springs hooked up to it that go 00:07:20.54000:07:20.550 down these little handle levers here so 00:07:23.30000:07:23.310 they're just basically kind of like a 00:07:25.61000:07:25.620 nonk got a little handle at the bottom 00:07:27.56000:07:27.570 you've got a groove cutting a piece of 00:07:29.42000:07:29.430 flat steel you just pull it down line it 00:07:32.48000:07:32.490 up with the groove and stick it in there 00:07:34.42000:07:34.430 same thing over here you just pull it 00:07:36.71000:07:36.720 down line up the groove and stick it in 00:07:38.33000:07:38.340 there and that gives us a pressure 00:07:39.80000:07:39.810 relief top so that if anything were to 00:07:41.75000:07:41.760 happen we get a backflash inside of the 00:07:43.70000:07:43.710 gasifier if anything were to happen some 00:07:46.64000:07:46.650 backblast aside the gasifier it blows 00:07:48.32000:07:48.330 off that pressure out through the lid 00:07:50.42000:07:50.430 the springs kind of open up for a moment 00:07:52.19000:07:52.200 give it the pop out the only other thing 00:07:54.65000:07:54.660 here I've got a hook so we can to get 00:07:56.84000:07:56.850 let me go ahead and unhook this there we 00:08:00.80000:08:00.810 go 00:08:02.38000:08:02.390 all right so we can turn the lid over 00:08:04.97000:08:04.980 here set it on there you can pull it all 00:08:08.00000:08:08.010 the way out and let it just hang on the 00:08:09.41000:08:09.420 hook that was kind of the whole idea 00:08:10.97000:08:10.980 here so you have somewhere to hold the 00:08:12.26000:08:12.270 lid while you fill it up so the very 00:08:14.09000:08:14.100 final pieces of fabricating our gasifier 00:08:16.46000:08:16.470 are completed and I just want to kind of 00:08:17.96000:08:17.970 show you those first of all here you can 00:08:20.42000:08:20.430 see a double ring a little air gap at 00:08:22.28000:08:22.290 the tip of my thumb right there 00:08:23.63000:08:23.640 that little air gap slides perfectly 00:08:25.94000:08:25.950 over this lip right here so we put this 00:08:28.63000:08:28.640 reactor down inside of our lower ash 00:08:31.07000:08:31.080 catch the reduction zone this part of it 00:08:33.71000:08:33.720 here slides inside of the ring that ring 00:08:36.50000:08:36.510 is going to slide up into that slot that 00:08:38.42000:08:38.430 you see right there that it created I'm 00:08:40.31000:08:40.320 going to put some oven stove door rope 00:08:42.56000:08:42.570 right here some graph Oh glass inside of 00:08:45.05000:08:45.060 there that will give us a really nice 00:08:46.22000:08:46.230 seal when we set this down inside of 00:08:48.31000:08:48.320 - catch also allows us to remove it 00:08:50.68000:08:50.690 later on for easy cleaning we've also 00:08:53.05000:08:53.060 got the cable now hooked up so our door 00:08:55.69000:08:55.700 stays shut I can pull on it as you can 00:08:57.43000:08:57.440 see there I've got just a simple hook 00:09:00.37000:09:00.380 holding on to our loop you undo that and 00:09:03.19000:09:03.200 once again that allows you to shake your 00:09:05.26000:09:05.270 screen at the bottom making sure the 00:09:07.36000:09:07.370 screen stays nice and clean and you push 00:09:09.79000:09:09.800 that back up on there and it's going to 00:09:11.11000:09:11.120 stay there so those were the simple last 00:09:13.78000:09:13.790 pieces that I needed to complete to make 00:09:15.94000:09:15.950 this a fully sealed and functioning 00:09:18.07000:09:18.080 system all right I just want to show you 00:09:20.23000:09:20.240 this at this point in the construction 00:09:21.22000:09:21.230 what we have is a true downdraft style 00:09:24.01000:09:24.020 gasifier I have no lid on top and we 00:09:26.56000:09:26.570 have our reduction zone so if we just 00:09:28.84000:09:28.850 left the lid off and we fed it full of 00:09:30.76000:09:30.770 material from the top here let the air 00:09:32.41000:09:32.420 draw be drawn in from the top right 00:09:34.54000:09:34.550 through the opening right there the air 00:09:36.34000:09:36.350 would draw to the wood mass down through 00:09:38.50000:09:38.510 the reduction zone paralysis zone and 00:09:40.57000:09:40.580 now it is wood gas through this output 00:09:43.09000:09:43.100 pipe here now what we're going to do is 00:09:45.19000:09:45.200 we're going to drill holes right about 00:09:47.05000:09:47.060 here first I'm going to start with four 00:09:49.27000:09:49.280 holes 00:09:49.90000:09:49.910 north-south-east-west then I'm going to 00:09:51.67000:09:51.680 go in between those the 00:09:53.05000:09:53.060 north-south-east-west four holes are 00:09:54.79000:09:54.800 going to be about half-inch diameter 00:09:56.65000:09:56.660 good thick steel tubing and those are 00:09:59.23000:09:59.240 going to be a high pressure jetting 00:10:00.73000:10:00.740 going in towards the center right at the 00:10:02.68000:10:02.690 top of our reduction zone so the air 00:10:04.48000:10:04.490 flow will go in and be drawn down 00:10:06.58000:10:06.590 through the reduction zones would mass 00:10:08.62000:10:08.630 and helping the paralysis process like I 00:10:11.08000:10:11.090 said just a moment ago if you wanted to 00:10:12.49000:10:12.500 use this is a really simple downdraft 00:10:14.47000:10:14.480 gasifier you wouldn't put the lid on and 00:10:16.54000:10:16.550 you would have left it just as it was 00:10:17.95000:10:17.960 because we have a design with the lid 00:10:20.08000:10:20.090 that's going to build pressure above the 00:10:21.40000:10:21.410 wood mass above the actual burning zone 00:10:23.71000:10:23.720 we're going to want to install a way for 00:10:25.99000:10:26.000 fresh air to get right down here to our 00:10:28.36000:10:28.370 paralysis area to our reduction zone and 00:10:31.06000:10:31.070 that's what you see here so I've 00:10:32.83000:10:32.840 installed 8 all the way around here 00:10:35.70000:10:35.710 around the bottom eight half-inch pieces 00:10:38.32000:10:38.330 of tubing that go all the way down let 00:10:41.11000:10:41.120 me show you inside and you can see them 00:10:43.78000:10:43.790 right there poking right out to the edge 00:10:48.51000:10:48.520 allowing it so the airflow from them 00:10:50.86000:10:50.870 will come right into the center here of 00:10:54.43000:10:54.440 our reduction zone right at the top of 00:10:56.14000:10:56.150 it allowing all the air to flow down 00:10:57.67000:10:57.680 through the reduction zone giving us a 00:10:59.29000:10:59.300 nice hot burn through that entire 00:11:01.11000:11:01.120 area let me go ahead and show you it 00:11:02.97000:11:02.980 from the other side real quick so you 00:11:04.29000:11:04.300 can see what it looks like 00:11:05.45000:11:05.460 lift it up if you look down inside so 00:11:10.89000:11:10.900 there you go you can see all the pipes 00:11:15.03000:11:15.040 coming down through there 00:11:16.26000:11:16.270 not really interfering in any way with 00:11:18.78000:11:18.790 the wood mass as it goes into the 00:11:20.70000:11:20.710 reduction zone they're all slightly 00:11:22.14000:11:22.150 curved so no the wood as it goes down 00:11:24.06000:11:24.070 through from the top here can actually 00:11:26.01000:11:26.020 fall into the tubes or into the pipe 00:11:27.75000:11:27.760 openings at the end there everything's 00:11:29.88000:11:29.890 going to move really nice and fluid 00:11:31.23000:11:31.240 right past them the air flows all nice 00:11:33.60000:11:33.610 and even coming in just at the top of a 00:11:35.55000:11:35.560 reduction zone a lot so the last step of 00:11:37.80000:11:37.810 this folks is to find a draw fan to get 00:11:40.50000:11:40.510 it started I'm gonna have to look for 00:11:42.39000:11:42.400 where to find one of those I'm pretty 00:11:43.71000:11:43.720 sure if I look in old RVs I can find one 00:11:46.26000:11:46.270 of those 12-volt 110 little fans they 00:11:49.29000:11:49.300 had in the heaters and that should work 00:11:50.97000:11:50.980 pretty well so I just got done showing 00:11:53.16000:11:53.170 you the air inlets around the bottom and 00:11:55.01900:11:55.029 now I've incorporated the very last part 00:11:56.70000:11:56.710 of this I was looking for a fan that 00:11:58.44000:11:58.450 would go in line with the actual output 00:12:00.51000:12:00.520 pipe but I couldn't find one locally so 00:12:02.94000:12:02.950 this is the fan I ended up finding it's 00:12:04.47000:12:04.480 from a pellet stove down at the local 00:12:06.39000:12:06.400 hardware store about $130 fan the way I 00:12:09.30000:12:09.310 made this work so it could seal off is 00:12:11.22000:12:11.230 that I added a two inch plate right here 00:12:14.64000:12:14.650 over the face of the fan you see the 00:12:16.94900:12:16.959 intake to the fan there some the 00:12:18.32900:12:18.339 squirrel cage in there and I've got a 00:12:20.16000:12:20.170 little piece of threaded pipe with a cap 00:12:22.38000:12:22.390 on it so once we get the system started 00:12:24.57000:12:24.580 I can go ahead and thread that back in 00:12:26.57900:12:26.589 there and seal it off so no air draws 00:12:28.98000:12:28.990 through the fan and into the gasifier 00:12:30.69000:12:30.700 because once the gas fires up and 00:12:32.31000:12:32.320 running once again your air intake is 00:12:34.53000:12:34.540 going to be these holes all the way 00:12:35.79000:12:35.800 around and I've got plugs in those these 00:12:37.41000:12:37.420 will be how you regulate how many of 00:12:39.57000:12:39.580 them you're using you can pull one of 00:12:41.01000:12:41.020 them out and just use one of them or you 00:12:43.05000:12:43.060 can go around and pull out every other 00:12:44.43000:12:44.440 one or you can go through and pull all 00:12:46.38000:12:46.390 eight of them out and that gives you the 00:12:48.09000:12:48.100 ability to kind of regulate the flow 00:12:49.76900:12:49.779 inside the stove I'm going to put a 00:12:51.12000:12:51.130 little bin here that can hold the plugs 00:12:52.92000:12:52.930 in there something you can set them down 00:12:54.78000:12:54.790 in when you're done so now our gasifying 00:12:56.97000:12:56.980 wood stove is completed and all we're 00:12:58.68000:12:58.690 going to do now is give it a primary 00:13:00.63000:13:00.640 test fire we're going to put some wood 00:13:02.46000:13:02.470 in there we're going to get it started 00:13:03.66000:13:03.670 up we're going to use a fan to get the 00:13:05.97000:13:05.980 wood gas-producing out of the bottom 00:13:07.68000:13:07.690 down here I'll remove the tank off the 00:13:09.00000:13:09.010 end that's part of a later on project is 00:13:11.37000:13:11.380 something we're going to install on 00:13:12.39000:13:12.400 there we're going to get the wood gas 00:13:13.86000:13:13.870 coming out of that 00:13:14.73000:13:14.740 type and see if we can't get it to light 00:13:16.13000:13:16.140 so now that we've built our gasifier 00:13:18.51000:13:18.520 obviously the next part of this is to 00:13:19.94900:13:19.959 test out to see if we can get good gas 00:13:21.81000:13:21.820 production so I've got a couple buckets 00:13:23.88000:13:23.890 full of chopped up wood here as you can 00:13:27.15000:13:27.160 see it's ready to go 00:13:28.86000:13:28.870 got another bucket of it right there 00:13:31.04000:13:31.050 this is going to be the first load we 00:13:33.32900:13:33.339 drop in there that's going to sit right 00:13:34.74000:13:34.750 down in the reduction zone right down 00:13:36.78000:13:36.790 inside of here that'll be the second 00:13:38.94000:13:38.950 load I put in there that's going to sit 00:13:40.19900:13:40.209 on top of the kind of the larger chunks 00:13:41.69900:13:41.709 then we're going to put newspaper which 00:13:43.98000:13:43.990 you see pile over there on top of that 00:13:45.75000:13:45.760 and we're going to get that started so 00:13:47.28000:13:47.290 we're going to get this little pile here 00:13:48.78000:13:48.790 up to temperature and then once that's 00:13:51.03000:13:51.040 got a bit of a cold bed going we're 00:13:52.59000:13:52.600 going to start dumping in our larger 00:13:53.94000:13:53.950 buckets of material all right so here we 00:13:56.16000:13:56.170 go first step obviously is done do our 00:13:58.67000:13:58.680 safety latches here open up the lid and 00:14:02.16000:14:02.170 rotate it out of the way and we're going 00:14:06.24000:14:06.250 to take our first load of wood I showed 00:14:07.76900:14:07.779 you feed that in there as much of it as 00:14:13.68000:14:13.690 I can get in there looks like a good fit 00:14:18.24000:14:18.250 we're now going to grab a bunch of this 00:14:20.49000:14:20.500 and put it on that same thing just like 00:14:23.51900:14:23.529 that and put some small starter sticks 00:14:26.88000:14:26.890 on the top of that 00:14:32.80000:14:32.810 I've got a little less to that and some 00:14:35.37900:14:35.389 newspaper we're going to drop some 00:14:38.53000:14:38.540 newspaper in on top a little more stick 00:14:44.18900:14:44.199 some more newspaper and there we go that 00:14:47.61900:14:47.629 is now ready to light so I'm going to go 00:14:49.50900:14:49.519 ahead light up a piece of paper get that 00:14:51.99900:14:52.009 down in there shut the lid and turn on 00:14:54.06900:14:54.079 the fan and show you how well it works 00:14:55.60000:14:55.610 alright folks so now we're ready to fire 00:14:57.55000:14:57.560 it up I loaded it up a little bit 00:14:58.96000:14:58.970 earlier I've been waiting for shadowing 00:15:00.61000:15:00.620 so we could see the flame from the wood 00:15:02.11000:15:02.120 gas a little bit better it's a very 00:15:03.55000:15:03.560 clear flame so it's going to be hard to 00:15:05.86000:15:05.870 see one of the things you see here is a 00:15:07.86900:15:07.879 piece of pipe ready to stick into place 00:15:10.11900:15:10.129 once we see a phase shift and the gas 00:15:12.42900:15:12.439 that's coming out of this pipe here 00:15:13.99000:15:14.000 phase shift means it's going to go kind 00:15:16.09000:15:16.100 of a boo ish color kind of your standard 00:15:17.94900:15:17.959 smoke color to more of kind of an orange 00:15:20.11000:15:20.120 color like a milky orange color and 00:15:23.25900:15:23.269 that's going to mean that we're into 00:15:24.67000:15:24.680 wood gas territory and one thing about 00:15:26.37900:15:26.389 the wood gases it needs to be cooled to 00:15:28.72000:15:28.730 become more denser and more flammable to 00:15:31.24000:15:31.250 get it to light so once I see that I'm 00:15:33.28000:15:33.290 going to pick up this pipe I'm going to 00:15:34.92900:15:34.939 stick it up over the end just like that 00:15:36.28000:15:36.290 and down here we're going to go and 00:15:38.11000:15:38.120 light it on fire I'm going to move the 00:15:39.51900:15:39.529 camera so you can see that a little 00:15:40.68900:15:40.699 better here we go 00:15:49.35000:15:49.360 so so I've lift up the lid turn on the 00:15:53.07900:15:53.089 fan let's see if it lights it nice and 00:16:00.93900:16:00.949 easy 00:16:07.38000:16:07.390 you can see the smoke coming out of 00:16:09.33000:16:09.340 there nice it's not dying down starting 00:16:12.24000:16:12.250 to see a little phase shift in the smoke 00:16:13.65000:16:13.660 so we're going to try one light up here 00:16:15.27000:16:15.280 now I'm going to do is stick this pipe 00:16:17.28000:16:17.290 right up over that come down here light 00:16:23.01000:16:23.020 the torch and watch the smoke disappear 00:16:30.28000:16:30.290 so there you go folks there is wood gas 00:16:32.67900:16:32.689 burning as long as I keep this pipe cool 00:16:36.51900:16:36.529 enough one of the problems here is I've 00:16:38.01900:16:38.029 got a very short radiator obviously so 00:16:40.41900:16:40.429 it's going to be a little difficult to 00:16:41.61900:16:41.629 keep it cool enough but there's the wood 00:16:44.16900:16:44.179 gas burning and I can pull that away and 00:16:46.71900:16:46.729 you can see the smoke once again let me 00:16:49.32900:16:49.339 hit it with the torches to light it and 00:16:52.94900:16:52.959 you'll watch it all clear up and a nice 00:16:55.47900:16:55.489 flame down here it's not quite perfectly 00:16:58.98900:16:58.999 there yet now that's wood gas at this 00:17:01.50900:17:01.519 point because it's unfiltered you 00:17:03.00900:17:03.019 probably don't want to run an engine on 00:17:04.41900:17:04.429 it 00:17:04.72000:17:04.730 but we could use it for cooking in the 00:17:06.18900:17:06.199 lanterns and anything that require 00:17:07.84000:17:07.850 basically a propane right now it's just 00:17:10.62900:17:10.639 having a problem staying cool you can 00:17:12.22000:17:12.230 see I've got a rag on the pipe I'm 00:17:13.68900:17:13.699 dousing with water as long as the gas 00:17:15.78900:17:15.799 gets cool it's flammable as this pipe 00:17:18.42900:17:18.439 heats up it's going to get less and less 00:17:19.92900:17:19.939 flammable with the gas because the 00:17:21.78900:17:21.799 temperature is too high once the 00:17:23.50000:17:23.510 temperature drops it becomes dense and a 00:17:25.38900:17:25.399 lot more flammable 00:17:30.82000:17:30.830 [Applause] 00:17:31.54000:17:31.550 [Music] 00:18:03.65000:18:03.660 so there it is burning without the torch 00:18:06.24000:18:06.250 we now have a nice clean gas being 00:18:08.70000:18:08.710 produced by our wood stove right now you 00:18:11.34000:18:11.350 can see some of the paint's still 00:18:12.42000:18:12.430 burning off of it when it's completely 00:18:14.43000:18:14.440 set in and won't smoke any longer and 00:18:16.71000:18:16.720 right now you're watching wood gas burn 00:18:18.84000:18:18.850 I just thought I'd walk you up real 00:18:21.06000:18:21.070 quick show you our wood gas flame it's a 00:18:24.75000:18:24.760 little difficult to see from the 00:18:25.89000:18:25.900 distance and got the torch here in my 00:18:29.01000:18:29.020 hand me turn that off so there you go 00:18:32.13000:18:32.140 folks nice and clean look at that that's 00:18:35.61000:18:35.620 all coming from our gasifier 00:18:42.38000:18:42.390 going pretty red down inside that hole 00:18:44.63000:18:44.640 so there you go once again we can walk 00:18:47.36000:18:47.370 down to the end in that hole time our 00:18:50.36000:18:50.370 wood gas torch is just burning away 00:18:53.13000:18:53.14000:18:54.28000:18:54.290 until next time folks I hope you enjoyed 00:18:56.87000:18:56.880 this is mr.
