00:00:00.060 well today on the boiling point we're 00:00:01.57900:00:01.589 going to talk about daily maintenance on 00:00:03.32000:00:03.330 your boiler room 00:00:19.41000:00:19.420 welcome to the boiling point we're here 00:00:21.52000:00:21.530 with 36 year veteran Michael Taylor 00:00:24.35900:00:24.369 Michael's actually in our safety 00:00:26.80000:00:26.810 department and heads all to the safety 00:00:28.78000:00:28.790 department of where but more importantly 00:00:30.55000:00:30.560 he's last word technically in the 00:00:33.10000:00:33.110 business so 36 years in the business got 00:00:35.35000:00:35.360 a lot of knowledge and so really I can't 00:00:37.45000:00:37.460 believe I haven't had you on the the 00:00:39.36900:00:39.379 boiling point yet so glad that you're 00:00:41.32000:00:41.330 finally with us here hey what we're 00:00:44.20000:00:44.210 talking about today's we're going to 00:00:45.34000:00:45.350 talk a little bit about daily 00:00:46.54000:00:46.550 maintenance of the boiler and taking 00:00:49.54000:00:49.550 care of the boiler and we thought we'd 00:00:51.04000:00:51.050 go through a checklist of things that 00:00:52.50900:00:52.519 you could do on a daily basis so Michael 00:00:54.82000:00:54.830 the first thing I believe that we would 00:00:56.92000:00:56.930 do is look a little bit about the blow 00:00:58.78000:00:58.790 downs 00:00:59.17000:00:59.180 yeah the the biggest point is to the 00:01:01.86900:01:01.879 main blowdown to get all the solids out 00:01:04.36000:01:04.370 of the boiler that's accumulated in 00:01:06.58000:01:06.590 there okay how those solids actually get 00:01:08.53000:01:08.540 to the bottom blowdown and they're 00:01:12.19000:01:12.200 they're heavier than the water so 00:01:13.78000:01:13.790 they're going to fall to the bottom the 00:01:15.85000:01:15.860 chemical in the boiler actually keeps it 00:01:17.80000:01:17.810 from attaching to the tubes and the 00:01:19.24000:01:19.250 other materials so they can't drop and 00:01:21.10000:01:21.110 you can blow them out okay so this is a 00:01:22.72000:01:22.730 daily thing that should be done once you 00:01:24.37000:01:24.380 go through that process real quick for 00:01:26.59000:01:26.600 us okay I main blowdown you you're going 00:01:29.17000:01:29.180 to have a quick opening and a slow 00:01:30.91000:01:30.920 opening on most boilers you always open 00:01:33.61000:01:33.620 the quick opening first it's just a 00:01:36.16000:01:36.170 backup you don't want to open it last 00:01:38.59000:01:38.600 you want to open the slope make sure 00:01:40.33000:01:40.340 that you don't stress the pipes and 00:01:42.19000:01:42.200 stuff and blow them off so you open the 00:01:44.08000:01:44.090 valve up all the way and depending on 00:01:46.72000:01:46.730 how long your chemical guide tells you 00:01:48.67000:01:48.680 to blow it then you close it back down 00:01:50.83000:01:50.840 typically it's going to be a ten-second 00:01:52.81000:01:52.820 blow okay and then shut your secondary 00:01:55.66000:01:55.670 valve back off all right we've moved to 00:01:58.21000:01:58.220 the front of the boiler now we're going 00:01:59.35000:01:59.360 to be doing the water columns Michael 00:02:01.30000:02:01.310 first of all what is the water column 00:02:02.68000:02:02.690 for it's to control the level of the 00:02:05.86000:02:05.870 water in the boiler and to prevent the 00:02:07.78000:02:07.790 blower from going out on low water so it 00:02:09.99900:02:10.009 it has switches in it that will shut the 00:02:13.78000:02:13.790 burner off if the water gets too low 00:02:15.30900:02:15.319 okay so what are we going to do going to 00:02:17.68000:02:17.690 daily maintenance on this well this you 00:02:20.44000:02:20.450 have settlement will settle in this bowl 00:02:22.72000:02:22.730 just like it does in the bottom the 00:02:24.16000:02:24.170 boiler so if you let it 00:02:25.36000:02:25.370 too much build in there then the float 00:02:27.75900:02:27.769 or the probes in this case will not 00:02:31.02000:02:31.030 they take a little water conditions so 00:02:32.61000:02:32.620 you have to blow that column down to 00:02:34.55900:02:34.569 blow all that sediment out and on on 00:02:37.80000:02:37.810 this one it's a probe so it doesn't 00:02:40.08000:02:40.090 matter how quickly you do it but if 00:02:41.88000:02:41.890 you've got a a float in there 00:02:44.61000:02:44.620 you have to do it very slowly or you'll 00:02:46.23000:02:46.240 collapse your float so you simply open 00:02:49.38000:02:49.390 the valve up all the way the time you 00:02:53.30900:02:53.319 get it open it's blown out so then you 00:02:55.65000:02:55.660 close it back down okay 00:02:57.60000:02:57.610 so it's not a ten second here no just 00:02:59.94000:02:59.950 open up and close it back down okay and 00:03:02.16000:03:02.170 when you do that the boiler the burner 00:03:05.31000:03:05.320 should shut down because it's going to 00:03:07.56000:03:07.570 drop the water off that switch if it 00:03:10.47000:03:10.480 doesn't shut down there's something 00:03:12.39000:03:12.400 wrong you need to shut it down and see 00:03:14.00900:03:14.019 what's wrong with it 00:03:14.75900:03:14.769 well having data is always important and 00:03:17.52000:03:17.530 this next thing that we're going to do 00:03:19.97900:03:19.989 is something that's also important tell 00:03:22.50000:03:22.510 us a little bit about the boiler 00:03:23.34000:03:23.350 pressure plea depending on your process 00:03:26.91000:03:26.920 you're going to have a certain set point 00:03:29.19000:03:29.200 on your boiler pressure and the ball 00:03:32.16000:03:32.170 it's going to fluctuate some depending 00:03:34.02000:03:34.030 on your load so you always want to check 00:03:36.53900:03:36.549 your your pressure when you add a steady 00:03:38.75900:03:38.769 load right not when it's you've got a 00:03:41.55000:03:41.560 big load surge or it's back way off 00:03:43.94900:03:43.959 whenever it's a steady load and check to 00:03:46.19900:03:46.209 make sure that your bores maintaining 00:03:48.06000:03:48.070 the pressure is this something that you 00:03:50.13000:03:50.140 would actually write down daily sure you 00:03:52.50000:03:52.510 should have a daily log book that you 00:03:54.96000:03:54.970 would write that down a lot of places 00:03:56.52000:03:56.530 they'll record that every hour and what 00:04:00.24000:04:00.250 would you use that information for just 00:04:02.52000:04:02.530 to see what your load is being on your 00:04:04.68000:04:04.690 board to make sure that your boiler is 00:04:06.09000:04:06.100 big enough and also to make sure that if 00:04:09.50900:04:09.519 your load hasn't changed that your 00:04:11.16000:04:11.170 boards working properly 00:04:12.72000:04:12.730 well we've moved back to the back of the 00:04:14.67000:04:14.680 boiler again and the stack seems to be 00:04:17.49000:04:17.500 something that is really really 00:04:19.19900:04:19.209 important to understand once you tell us 00:04:21.59900:04:21.609 a little about the stack well the stack 00:04:23.67000:04:23.680 will in stack temperature will tell you 00:04:26.58000:04:26.590 what's going on inside the boiler 00:04:28.14000:04:28.150 because scale is a great insulator soot 00:04:32.25000:04:32.260 is a great insulator either one of them 00:04:34.23000:04:34.240 is going to cut down the efficiency and 00:04:35.90900:04:35.919 allow more heat to go out your stack 00:04:37.83000:04:37.840 okay so if you check your stack 00:04:40.74000:04:40.750 temperature daily the stack temperature 00:04:43.08000:04:43.090 should always be from 00:04:44.76000:04:44.770 1,500 degrees above your steam 00:04:46.77000:04:46.780 temperature okay so if you've got 325 00:04:50.43000:04:50.440 degrees steam temperature 225 psi then 00:04:52.95000:04:52.960 your stocks going be between 375 and 425 00:04:55.98000:04:55.990 if it gets out of that it starts rising 00:04:58.40900:04:58.419 you know something is going haywire 00:05:00.83900:05:00.849 inside the board okay and typically when 00:05:03.05900:05:03.069 that stock temperature is going up a lot 00:05:04.80000:05:04.810 of times it is a suet problem and maybe 00:05:07.35000:05:07.360 a scaling problem something like it's 00:05:08.96900:05:08.979 going to be one of the other either acid 00:05:10.92000:05:10.930 or scaling and either one makes it well 00:05:13.43900:05:13.449 really inefficient because you're 00:05:15.11900:05:15.129 sending more heat out instead of 00:05:16.58900:05:16.599 transferring it to your 16 okay all 00:05:19.58900:05:19.599 right well we've moved to the fuel side 00:05:21.02900:05:21.039 of things and what do we do with gas 00:05:23.49000:05:23.500 here Mike well you got your gas very 00:05:27.33000:05:27.340 buddy which is regulating your gas going 00:05:29.87900:05:29.889 to the burner so it's real important 00:05:31.62000:05:31.630 that you check to make sure that your 00:05:33.99000:05:34.000 you got a good gas supply to it and that 00:05:36.62900:05:36.639 your regulator is working with the gauge 00:05:39.08900:05:39.099 after the regulator if it stops working 00:05:41.82000:05:41.830 then you guess what you should check it 00:05:43.83000:05:43.840 but it's a good daily load to load those 00:05:46.05000:05:46.060 pressures to make sure everything is 00:05:47.36900:05:47.379 supposed to be okay now that's gas 00:05:50.24900:05:50.259 now what about oil with oil you have a 00:05:53.33900:05:53.349 an old filter and you have a back engage 00:05:57.14900:05:57.159 between the pump and the filter and that 00:05:58.80000:05:58.810 backing gates will tell you that the 00:06:01.46900:06:01.479 filter is getting stuck when those 00:06:02.61000:06:02.620 filters getting stopped up okay so as 00:06:05.15900:06:05.169 the gauge rises in vacuum you know to 00:06:08.79000:06:08.800 need to change your filter out okay so 00:06:10.40900:06:10.419 no fuel probably hard for the burner to 00:06:12.93000:06:12.940 work yes very hard well we come back to 00:06:16.17000:06:16.180 the back of the boiler again and we're 00:06:17.90900:06:17.919 actually going to look into the site 00:06:19.98000:06:19.990 board for looking at the flame I 00:06:22.11000:06:22.120 remember as a little kid I'd be hanging 00:06:23.51900:06:23.529 out with my dad not always going to the 00:06:25.29000:06:25.300 boiler room and I always felt like a big 00:06:27.42000:06:27.430 boiler man because I could look into the 00:06:29.07000:06:29.080 site port so I still don't know what I'm 00:06:31.35000:06:31.360 looking at Mike so why don't you tell us 00:06:32.79000:06:32.800 a little bit about what what are we 00:06:34.62000:06:34.630 looking for in here well we're looking 00:06:36.54000:06:36.550 for to make sure that the flame stays 00:06:38.71900:06:38.729 like it always is 00:06:40.58900:06:40.599 every boiler is different but you'll get 00:06:43.70900:06:43.719 used to what the flame looks like so 00:06:45.42000:06:45.430 then when something goes how you are 00:06:47.27900:06:47.289 like the diffuser or something on the 00:06:49.52900:06:49.539 burner head you'll know it because 00:06:51.93000:06:51.940 you've been looking in there every day 00:06:53.18900:06:53.199 you say hey something 00:06:54.99000:06:55.000 changed so then you'll know to call 00:06:57.12000:06:57.130 somebody or to check into something and 00:06:59.37000:06:59.380 you also look and see if you're building 00:07:01.08000:07:01.090 up clinkers or anything because you can 00:07:03.03000:07:03.040 see the Morrison to when you're looking 00:07:04.62000:07:04.630 there with the flame in it 00:07:05.82000:07:05.830 you can see all that area so you can see 00:07:07.89000:07:07.900 if something is building up in there and 00:07:10.25000:07:10.260 causing a problem okay what why don't 00:07:12.93000:07:12.940 you explain flame impingement what that 00:07:16.29000:07:16.300 flame impingement means that you've your 00:07:18.51000:07:18.520 flame is actually instead of going 00:07:20.16000:07:20.170 straight down the tube it's varying to 00:07:22.92000:07:22.930 one side or up or down and really 00:07:25.41000:07:25.420 hitting on the metal hard and then it 00:07:27.48000:07:27.490 won't allow it to burn so it'll start 00:07:30.60000:07:30.610 building up carbon which is unburnt fuel 00:07:33.06000:07:33.070 and what we call in the boy industry 00:07:36.69000:07:36.700 it's a Deadman and and it'll it can get 00:07:39.84000:07:39.850 pretty big in there and actually start 00:07:41.76000:07:41.770 closing off the area so in the mold that 00:07:43.71000:07:43.720 grows the more engagement you have so 00:07:46.17000:07:46.180 the worse it gets 00:07:47.01000:07:47.020 okay so something really important that 00:07:49.02000:07:49.030 this needs to become something that 00:07:51.63000:07:51.640 you're just very familiar with your 00:07:53.19000:07:53.200 flame it's just understanding it it's 00:07:54.90000:07:54.910 just nice and it's just as gaudy no just 00:07:56.90900:07:56.919 look through that every day or several 00:07:58.98000:07:58.990 times a day and you get accustomed to 00:08:01.05000:08:01.060 what it's supposed to look like and soon 00:08:03.00000:08:03.010 as something changes you know it right 00:08:05.15900:08:05.169 off the bat because you're used to see 00:08:06.87000:08:06.880 it well obviously the boiler is 00:08:09.12000:08:09.130 something that's important and we should 00:08:10.53000:08:10.540 really look at but man there's a lot of 00:08:12.42000:08:12.430 support equipment that goes with a 00:08:14.48000:08:14.490 boiler so why don't we talk a little bit 00:08:16.68000:08:16.690 about the next step and that is some of 00:08:18.60000:08:18.610 the support equipment okay you got the 00:08:21.71900:08:21.729 feed tank or da tank depending on your 00:08:25.44000:08:25.450 application here we have a regular 00:08:28.65000:08:28.660 condensate tank and we've got a chemical 00:08:31.26000:08:31.270 pump here that's feeding chemical into 00:08:33.69000:08:33.700 the system you always check that 00:08:35.88000:08:35.890 everyday to make sure that one you've 00:08:38.61000:08:38.620 got a ample amount of chemical and that 00:08:42.08900:08:42.099 you haven't got any leaks and the pump 00:08:43.95000:08:43.960 is actually pumping okay then on top of 00:08:48.87000:08:48.880 that you have a this tank is also heated 00:08:51.90000:08:51.910 you heat the water up so that the bore 00:08:54.60000:08:54.610 doesn't have to work so hard so that you 00:08:56.34000:08:56.350 don't shock the boiler 00:08:57.39000:08:57.400 so there's temperature gauge on here and 00:09:00.00000:09:00.010 a heater that speed steam into the tank 00:09:02.31000:09:02.320 so you always want to check that to make 00:09:03.96000:09:03.970 sure your 00:09:04.40000:09:04.410 here is working probably you're not 00:09:05.80900:09:05.819 shocking damaging your bowler from cold 00:09:08.15000:09:08.160 water right okay then you can have water 00:09:11.93000:09:11.940 softeners and other chemical feed tanks 00:09:15.81900:09:15.829 you have to check the salt every day to 00:09:19.00900:09:19.019 make sure to Gus salt in your softeners 00:09:20.86900:09:20.879 to make sure all those things are 00:09:22.81900:09:22.829 working properly like the supposed to be 00:09:24.94900:09:24.959 okay so real important to just check the 00:09:27.49900:09:27.509 salt levels right salt is what cleans 00:09:32.38900:09:32.399 the salt and round so they can do this 00:09:34.91000:09:34.920 job okay alright well now we're going 00:09:38.09000:09:38.100 into water quality which we know is 00:09:41.24000:09:41.250 something that's extremely important and 00:09:43.04000:09:43.050 a lot of folks really don't take care of 00:09:46.10000:09:46.110 so you know talking a little bit about 00:09:48.59000:09:48.600 the water quality and actually how we 00:09:50.96000:09:50.970 even know that the quality is good what 00:09:53.54000:09:53.550 do we what do we do well it takes 00:09:55.99900:09:56.009 samples every day to make sure that that 00:09:58.97000:09:58.980 your water coming in is good and that 00:10:01.30900:10:01.319 what you're doing with your chemical and 00:10:03.35000:10:03.360 your blowdown is working for them so 00:10:06.07900:10:06.089 first you take a sample of your of your 00:10:08.05900:10:08.069 makeup water with its soft water city 00:10:10.55000:10:10.560 water or what it is to see that it's 00:10:13.55000:10:13.560 maintaining where you thought it was so 00:10:16.49000:10:16.500 that you know what that your chemical 00:10:17.84000:10:17.850 program is going to work okay because 00:10:19.79000:10:19.800 your chemical program is set up 00:10:21.23000:10:21.240 depending on what this water is which is 00:10:23.44900:10:23.459 different in every area because of the 00:10:25.00900:10:25.019 hardness of the water because the 00:10:26.21000:10:26.220 hardness of water whether you're on a 00:10:27.47000:10:27.480 softer or you're on deionized water what 00:10:30.41000:10:30.420 kind of water supply you have okay then 00:10:33.43900:10:33.449 you're going to have to take a sample of 00:10:34.93900:10:34.949 your tank to see because you've got time 00:10:38.26900:10:38.279 state coming back which is distilled 00:10:40.63900:10:40.649 water so you don't have any solids in it 00:10:42.71000:10:42.720 but you're making up water so you've got 00:10:44.42000:10:44.430 a mixture so you have to take a sample 00:10:46.75900:10:46.769 back down here to see what your water is 00:10:51.25900:10:51.269 see how much chemical you need to add 00:10:52.79000:10:52.800 okay alright and then you take a sample 00:10:55.75900:10:55.769 of your boiler water so you can take it 00:10:58.42000:10:58.430 you'll have a sample port set up on the 00:11:00.94900:11:00.959 ball or someplace 00:11:01.67000:11:01.680 this one is on the site glass you would 00:11:03.88900:11:03.899 take it right after you did your 00:11:04.99900:11:05.009 bro-down that way you've got fresh water 00:11:06.86000:11:06.870 in it so you can take your sample to see 00:11:09.31900:11:09.329 if your chemical program is working in 00:11:11.96000:11:11.970 the board and your blowdown program is 00:11:14.80900:11:14.819 or 00:11:15.07900:11:15.089 properly okay right well if you want to 00:11:18.59000:11:18.600 learn a little bit more about the water 00:11:20.03000:11:20.040 softeners you can click or rate here and 00:11:22.63900:11:22.649 we actually did a boiling point on the 00:11:24.98000:11:24.990 water softeners and actually how they 00:11:26.50900:11:26.519 work so make sure you check those out I 00:11:28.28000:11:28.290 believe that's it we've covered all the 00:11:30.37900:11:30.389 daily maintenance this is something that 00:11:32.03000:11:32.040 we're going to be back each every other 00:11:34.24900:11:34.259 week and we're going to be talking about 00:11:35.50900:11:35.519 more than room maintenance from a daily 00:11:37.81900:11:37.829 basis from a weekly basis you know from 00:11:41.09000:11:41.100 some annual type things that you need to 00:11:43.18900:11:43.199 do so tune in next time Mike appreciate 00:11:45.19900:11:45.209 you hanging out with us and we'll see 00:11:46.91000:11:46.920 you next time on the boiling point 00:11:48.67900:11:48.689 we appreciate Mike stopping by and 00:11:50.66000:11:50.670 talking to us a little bit about the 00:11:52.00900:11:52.019 daily boiler maintenance you know boiler 00:11:53.96000:11:53.970 equipment failures they can be dangerous 00:11:55.42900:11:55.439 and they typically result in lost 00:11:57.47000:11:57.480 productivity and revenue scaling a 00:11:59.98900:11:59.999 boiler on the water side will cause 00:12:01.51900:12:01.529 overheating and those result in boiler 00:12:03.92000:12:03.930 failure when this occurs sometimes there 00:12:06.19900:12:06.209 can be catastrophic failures that result 00:12:08.38900:12:08.399 in a water side or fire side explosions 00:12:10.57900:12:10.589 this has more serious consequence as 00:12:13.48000:12:13.490 including actually injuries or maybe 00:12:16.30900:12:16.319 even death and possible facility damage 00:12:19.24900:12:19.259 with the right preventative maintenance 00:12:20.78000:12:20.790 plan these issues can be avoided or 00:12:23.23900:12:23.249 greatly reduced we appreciate you 00:12:26.03000:12:26.040 stopping by make sure you like us on 00:12:27.79900:12:27.809 Facebook and follow us on Twitter and if
