00:00:00.060 well the snow is melting temperatures 00:00:02.11900:00:02.129 are rising and it's time to start 00:00:04.24900:00:04.259 thinking a little bit about that opening 00:00:05.90000:00:05.910 close we're gonna be talking about that 00:00:07.84900:00:07.859 today on the boiling point 00:00:15.82000:00:15.830 let's Daniel where our operations 00:00:18.32000:00:18.330 manager here at where yes we are related 00:00:21.67900:00:21.689 to much younger much taller uglier but 00:00:26.57000:00:26.580 anyway hey we're talking about open and 00:00:28.37000:00:28.380 closed today Daniel once you talk a 00:00:30.23000:00:30.240 little bit about the open and closed why 00:00:32.65900:00:32.669 we have them and just basically what you 00:00:35.51000:00:35.520 do okay when we do an open and close for 00:00:38.90000:00:38.910 for our annual inspection we're going 00:00:41.29900:00:41.309 through we're opening up all the fire 00:00:43.34000:00:43.350 side on the boiler you're opening up all 00:00:45.22900:00:45.239 the water side and what you're looking 00:00:47.27000:00:47.280 for is you're looking for scale and the 00:00:50.11900:00:50.129 boiler as well as you're looking for any 00:00:52.25000:00:52.260 type of soot buildup on your fire side 00:00:55.18000:00:55.190 when you're on from the fire side from a 00:00:58.63900:00:58.649 scale buildup standpoint you know about 00:01:01.27900:01:01.289 an eighth inch in the fire side is 00:01:02.95900:01:02.969 equivalent to about a forty seven 00:01:04.75900:01:04.769 percent heat loss so you want to make 00:01:06.64900:01:06.659 sure that the the fire side of your 00:01:09.53000:01:09.540 boiler is in good shape and is nice and 00:01:11.87000:01:11.880 cleaned out now when when you're doing 00:01:14.12000:01:14.130 the inspections is this something that's 00:01:15.62000:01:15.630 done annually on fire tubes that are 00:01:19.55000:01:19.560 steam or hot water what's both it's done 00:01:23.74900:01:23.759 annually for high pressure units if it's 00:01:26.35900:01:26.369 15-pound design systems that's every two 00:01:28.96900:01:28.979 years okay all right well Daniel we're 00:01:32.09000:01:32.100 back here on the the rear door here 00:01:35.02000:01:35.030 basically are they opening up everything 00:01:37.85000:01:37.860 when we're doing that open and close 00:01:39.73000:01:39.740 absolutely you want to take your your 00:01:42.23000:01:42.240 top doors off as well as open up the 00:01:44.56900:01:44.579 your main rear door 00:01:46.85000:01:46.860 when you're opening all this up what 00:01:48.80000:01:48.810 you're really looking for again you're 00:01:50.24000:01:50.250 looking at the fire side as well as the 00:01:52.31000:01:52.320 refractory on the back door you're 00:01:54.41000:01:54.420 making sure that the refractory is 00:01:55.78900:01:55.799 intact if it's the refractories all 00:01:57.56000:01:57.570 falling out we can do minor repairs but 00:02:00.85900:02:00.869 but if it's all falling out you take the 00:02:02.45000:02:02.460 risk of burning up your rear door so you 00:02:04.76000:02:04.770 always want to make sure that the 00:02:05.81000:02:05.820 refractory is in is 00:02:07.10000:02:07.110 good shape any type of cracks I mean is 00:02:09.23000:02:09.240 there a certain crack that you're like 00:02:10.52000:02:10.530 you know what we've got to fix that you 00:02:12.05000:02:12.060 know it's really just you know a lot of 00:02:14.15000:02:14.160 judgment calls if you can stick your 00:02:15.77000:02:15.780 finger in it it's probably gonna be too 00:02:17.12000:02:17.130 big okay we like to go through and pick 00:02:19.79000:02:19.800 out some of the refractory and then we 00:02:21.41000:02:21.420 can do some minor patching on it okay 00:02:23.57000:02:23.580 now as far as the tubes obviously you're 00:02:25.94000:02:25.950 seeing the the back side of the tube 00:02:27.83000:02:27.840 right and the tube sheet so you're 00:02:30.47000:02:30.480 inspecting that as well absolutely okay 00:02:32.57000:02:32.580 absolutely if you do find cracks in the 00:02:35.60000:02:35.610 tube sheet which is a good indication of 00:02:38.48000:02:38.490 fire cracks it's always good to do a 00:02:40.64000:02:40.650 mattock particle test on the tube sheet 00:02:42.92000:02:42.930 so you can get that crack repaired to 00:02:45.19900:02:45.209 eliminate any damage that could occur 00:02:46.67000:02:46.680 okay all right so we walk around here to 00:02:49.25000:02:49.260 the hand hole right and maybe talk a 00:02:52.34000:02:52.350 little bit about the hand hole and what 00:02:54.44000:02:54.450 we're looking for once we get that out 00:02:55.69900:02:55.709 right the hand holes are in place just 00:02:57.22900:02:57.239 for inspection purposes when you take 00:03:00.59000:03:00.600 these out you're really going to look at 00:03:01.94000:03:01.950 your water side or your tubes to look at 00:03:04.55000:03:04.560 the scale okay you can have a little bit 00:03:07.16000:03:07.170 of scale in the tubes 00:03:08.38000:03:08.390 1/32 of an inch of scale is equivalent 00:03:12.05000:03:12.060 to a 2% increase in fuel consumption if 00:03:17.18000:03:17.190 they actually once you actually take 00:03:19.13000:03:19.140 that scale off you have the bare tube 00:03:22.10000:03:22.110 what are you looking at and looking for 00:03:25.03900:03:25.049 if you will on that tube to say you know 00:03:27.05000:03:27.060 hey this is this boiler needs to be very 00:03:28.46000:03:28.470 tubed or whatever yeah again you're 00:03:31.22000:03:31.230 really looking at the tubes as well 00:03:33.02000:03:33.030 looking to see if there's any type of 00:03:34.46000:03:34.470 pitting they may be in those tubes that 00:03:36.83000:03:36.840 could be from oxidation 00:03:38.27000:03:38.280 I mean type of chemical pitting any any 00:03:41.63000:03:41.640 type of that okay and I'm assuming the 00:03:43.94000:03:43.950 scale is actually formed when there's 00:03:46.55000:03:46.560 just too much chemical it could be too 00:03:49.22000:03:49.230 much chemical not enough blowdown just 00:03:51.44000:03:51.450 from your your surface blowdown not 00:03:53.72000:03:53.730 blowing off getting all of your total 00:03:55.40000:03:55.410 dissolved solids off the top of the 00:03:57.02000:03:57.030 water okay 00:03:58.00900:03:58.019 definitely something then make sure that 00:03:59.93000:03:59.940 on a regular maintenance schedule that 00:04:02.06000:04:02.070 you're actually blowing the boiler down 00:04:03.47000:04:03.480 lutely 00:04:04.52000:04:04.530 we always recommend a blowdown once 00:04:06.53000:04:06.540 every eight hour shift 00:04:07.67000:04:07.680 alright good alright well Daniel do the 00:04:10.69900:04:10.709 inspectors are they actually on the 00:04:12.65000:04:12.660 jobsite when this is going on yeah your 00:04:16.01000:04:16.020 inspectors will come on the jobsite once 00:04:18.17000:04:18.180 you're ready for them to inspect the 00:04:19.69900:04:19.709 boiler 00:04:20.89000:04:20.900 what you're wanting to get ready for 00:04:22.90900:04:22.919 them you're obviously you're wanting to 00:04:24.17000:04:24.180 have everything on your fireside and 00:04:26.57000:04:26.580 water side removed and that includes all 00:04:30.40900:04:30.419 your caps crosses and McDonnell Miller 00:04:34.10000:04:34.110 heads so they can inspect your water 00:04:37.07000:04:37.080 column look through the your control 00:04:39.92000:04:39.930 line to make sure there's not a buildup 00:04:41.60000:04:41.610 of scale in there that could that could 00:04:44.84000:04:44.850 limit your operating controls from 00:04:47.27000:04:47.280 working properly 00:04:48.11000:04:48.120 okay and so he's on site and he'll 00:04:50.48000:04:50.490 actually look through all of this and 00:04:52.15900:04:52.169 and decide whether or not this is 00:04:53.75000:04:53.760 something that he can pass that's right 00:04:56.18000:04:56.190 okay okay so on this mcdonald miller the 00:04:59.27000:04:59.280 head if you will what are they looking 00:05:01.76000:05:01.770 for and they're again they're looking 00:05:04.34000:05:04.350 inside of here to make sure that there's 00:05:06.29000:05:06.300 not an excessive buildup of scale that 00:05:09.26000:05:09.270 could limit the float from working 00:05:11.62900:05:11.639 properly or that could clog this line up 00:05:15.11000:05:15.120 that could stop that line up and and 00:05:18.14000:05:18.150 trick this thing to look like it's full 00:05:19.85000:05:19.860 of water 00:05:20.45000:05:20.460 okay okay obviously the man way on top 00:05:23.71900:05:23.729 of the boiler that needs to be out as 00:05:26.33000:05:26.340 well for yes absolutely they can 00:05:27.86000:05:27.870 actually look down and see the tubes yes 00:05:29.99000:05:30.000 okay yes all right so the inspector he 00:05:33.40900:05:33.419 checks out everything everything's great 00:05:36.68000:05:36.690 i'm assuming from there you're filling 00:05:40.55000:05:40.560 the boiler yeah everything back well 00:05:41.93000:05:41.940 yeah once once that's complete and you 00:05:43.73000:05:43.740 get your clean bill you go through and 00:05:46.64000:05:46.650 you put all new gaskets on the fire side 00:05:48.58900:05:48.599 waterside manway put put your caps and 00:05:51.98000:05:51.990 crosses your McDonnell Miller head back 00:05:53.71900:05:53.729 on you button the boiler up you go ahead 00:05:56.77900:05:56.789 and fill it up and get ready for your 00:05:59.29000:05:59.300 test fire okay and upon that test fire 00:06:02.83900:06:02.849 I'm assuming we're moving into the 00:06:04.27900:06:04.289 burner and we want to make sure that 00:06:05.90000:06:05.910 everything is it's in tune yeah it's 00:06:10.07000:06:10.080 always a great practice once you're done 00:06:12.17000:06:12.180 and go ahead and put a put an analyzer 00:06:14.24000:06:14.250 on the boiler and check it and make sure 00:06:16.96900:06:16.979 your o twos are where they need to be 00:06:18.37000:06:18.380 make sure you have proper combustion 00:06:20.48000:06:20.490 safeties yes absolutely we always check 00:06:24.71000:06:24.720 your Safety's your high limits you're 00:06:27.11000:06:27.120 running interlocks to make sure 00:06:29.08900:06:29.099 everything is functioning so you have a 00:06:30.56000:06:30.570 safely operated piece of equipment 00:06:33.21000:06:33.220 so the boiler gets all started up it's 00:06:35.01000:06:35.020 all tuned and I guess highly efficient 00:06:39.30000:06:39.310 and really an optimal performance after 00:06:41.91000:06:41.920 a boiler absolute affection absolutely 00:06:43.98000:06:43.990 hi ma'am appreciate you stopping Batman 00:06:45.84000:06:45.850 thanks for hanging out and make sure you 00:06:48.42000:06:48.430 check out the website you see a little
