well the snow is melting temperatures
00:00:02.119 00:00:02.129 are rising and it's time to start
00:00:04.249 00:00:04.259 thinking a little bit about that opening
00:00:05.900 00:00:05.910 close we're gonna be talking about that
00:00:07.849 00:00:07.859 today on the boiling point
00:00:15.820 00:00:15.830 let's Daniel where our operations
00:00:18.320 00:00:18.330 manager here at where yes we are related
00:00:21.679 00:00:21.689 to much younger much taller uglier but
00:00:26.570 00:00:26.580 anyway hey we're talking about open and
00:00:28.370 00:00:28.380 closed today Daniel once you talk a
00:00:30.230 00:00:30.240 little bit about the open and closed why
00:00:32.659 00:00:32.669 we have them and just basically what you
00:00:35.510 00:00:35.520 do okay when we do an open and close for
00:00:38.900 00:00:38.910 for our annual inspection we're going
00:00:41.299 00:00:41.309 through we're opening up all the fire
00:00:43.340 00:00:43.350 side on the boiler you're opening up all
00:00:45.229 00:00:45.239 the water side and what you're looking
00:00:47.270 00:00:47.280 for is you're looking for scale and the
00:00:50.119 00:00:50.129 boiler as well as you're looking for any
00:00:52.250 00:00:52.260 type of soot buildup on your fire side
00:00:55.180 00:00:55.190 when you're on from the fire side from a
00:00:58.639 00:00:58.649 scale buildup standpoint you know about
00:01:01.279 00:01:01.289 an eighth inch in the fire side is
00:01:02.959 00:01:02.969 equivalent to about a forty seven
00:01:04.759 00:01:04.769 percent heat loss so you want to make
00:01:06.649 00:01:06.659 sure that the the fire side of your
00:01:09.530 00:01:09.540 boiler is in good shape and is nice and
00:01:11.870 00:01:11.880 cleaned out now when when you're doing
00:01:14.120 00:01:14.130 the inspections is this something that's
00:01:15.620 00:01:15.630 done annually on fire tubes that are
00:01:19.550 00:01:19.560 steam or hot water what's both it's done
00:01:23.749 00:01:23.759 annually for high pressure units if it's
00:01:26.359 00:01:26.369 15-pound design systems that's every two
00:01:28.969 00:01:28.979 years okay all right well Daniel we're
00:01:32.090 00:01:32.100 back here on the the rear door here
00:01:35.020 00:01:35.030 basically are they opening up everything
00:01:37.850 00:01:37.860 when we're doing that open and close
00:01:39.730 00:01:39.740 absolutely you want to take your your
00:01:42.230 00:01:42.240 top doors off as well as open up the
00:01:44.569 00:01:44.579 your main rear door
00:01:46.850 00:01:46.860 when you're opening all this up what
00:01:48.800 00:01:48.810 you're really looking for again you're
00:01:50.240 00:01:50.250 looking at the fire side as well as the
00:01:52.310 00:01:52.320 refractory on the back door you're
00:01:54.410 00:01:54.420 making sure that the refractory is
00:01:55.789 00:01:55.799 intact if it's the refractories all
00:01:57.560 00:01:57.570 falling out we can do minor repairs but
00:02:00.859 00:02:00.869 but if it's all falling out you take the
00:02:02.450 00:02:02.460 risk of burning up your rear door so you
00:02:04.760 00:02:04.770 always want to make sure that the
00:02:05.810 00:02:05.820 refractory is in is
00:02:07.100 00:02:07.110 good shape any type of cracks I mean is
00:02:09.230 00:02:09.240 there a certain crack that you're like
00:02:10.520 00:02:10.530 you know what we've got to fix that you
00:02:12.050 00:02:12.060 know it's really just you know a lot of
00:02:14.150 00:02:14.160 judgment calls if you can stick your
00:02:15.770 00:02:15.780 finger in it it's probably gonna be too
00:02:17.120 00:02:17.130 big okay we like to go through and pick
00:02:19.790 00:02:19.800 out some of the refractory and then we
00:02:21.410 00:02:21.420 can do some minor patching on it okay
00:02:23.570 00:02:23.580 now as far as the tubes obviously you're
00:02:25.940 00:02:25.950 seeing the the back side of the tube
00:02:27.830 00:02:27.840 right and the tube sheet so you're
00:02:30.470 00:02:30.480 inspecting that as well absolutely okay
00:02:32.570 00:02:32.580 absolutely if you do find cracks in the
00:02:35.600 00:02:35.610 tube sheet which is a good indication of
00:02:38.480 00:02:38.490 fire cracks it's always good to do a
00:02:40.640 00:02:40.650 mattock particle test on the tube sheet
00:02:42.920 00:02:42.930 so you can get that crack repaired to
00:02:45.199 00:02:45.209 eliminate any damage that could occur
00:02:46.670 00:02:46.680 okay all right so we walk around here to
00:02:49.250 00:02:49.260 the hand hole right and maybe talk a
00:02:52.340 00:02:52.350 little bit about the hand hole and what
00:02:54.440 00:02:54.450 we're looking for once we get that out
00:02:55.699 00:02:55.709 right the hand holes are in place just
00:02:57.229 00:02:57.239 for inspection purposes when you take
00:03:00.590 00:03:00.600 these out you're really going to look at
00:03:01.940 00:03:01.950 your water side or your tubes to look at
00:03:04.550 00:03:04.560 the scale okay you can have a little bit
00:03:07.160 00:03:07.170 of scale in the tubes
00:03:08.380 00:03:08.390 1/32 of an inch of scale is equivalent
00:03:12.050 00:03:12.060 to a 2% increase in fuel consumption if
00:03:17.180 00:03:17.190 they actually once you actually take
00:03:19.130 00:03:19.140 that scale off you have the bare tube
00:03:22.100 00:03:22.110 what are you looking at and looking for
00:03:25.039 00:03:25.049 if you will on that tube to say you know
00:03:27.050 00:03:27.060 hey this is this boiler needs to be very
00:03:28.460 00:03:28.470 tubed or whatever yeah again you're
00:03:31.220 00:03:31.230 really looking at the tubes as well
00:03:33.020 00:03:33.030 looking to see if there's any type of
00:03:34.460 00:03:34.470 pitting they may be in those tubes that
00:03:36.830 00:03:36.840 could be from oxidation
00:03:38.270 00:03:38.280 I mean type of chemical pitting any any
00:03:41.630 00:03:41.640 type of that okay and I'm assuming the
00:03:43.940 00:03:43.950 scale is actually formed when there's
00:03:46.550 00:03:46.560 just too much chemical it could be too
00:03:49.220 00:03:49.230 much chemical not enough blowdown just
00:03:51.440 00:03:51.450 from your your surface blowdown not
00:03:53.720 00:03:53.730 blowing off getting all of your total
00:03:55.400 00:03:55.410 dissolved solids off the top of the
00:03:57.020 00:03:57.030 water okay
00:03:58.009 00:03:58.019 definitely something then make sure that
00:03:59.930 00:03:59.940 on a regular maintenance schedule that
00:04:02.060 00:04:02.070 you're actually blowing the boiler down
00:04:03.470 00:04:03.480 lutely
00:04:04.520 00:04:04.530 we always recommend a blowdown once
00:04:06.530 00:04:06.540 every eight hour shift
00:04:07.670 00:04:07.680 alright good alright well Daniel do the
00:04:10.699 00:04:10.709 inspectors are they actually on the
00:04:12.650 00:04:12.660 jobsite when this is going on yeah your
00:04:16.010 00:04:16.020 inspectors will come on the jobsite once
00:04:18.170 00:04:18.180 you're ready for them to inspect the
00:04:19.699 00:04:19.709 boiler
00:04:20.890 00:04:20.900 what you're wanting to get ready for
00:04:22.909 00:04:22.919 them you're obviously you're wanting to
00:04:24.170 00:04:24.180 have everything on your fireside and
00:04:26.570 00:04:26.580 water side removed and that includes all
00:04:30.409 00:04:30.419 your caps crosses and McDonnell Miller
00:04:34.100 00:04:34.110 heads so they can inspect your water
00:04:37.070 00:04:37.080 column look through the your control
00:04:39.920 00:04:39.930 line to make sure there's not a buildup
00:04:41.600 00:04:41.610 of scale in there that could that could
00:04:44.840 00:04:44.850 limit your operating controls from
00:04:47.270 00:04:47.280 working properly
00:04:48.110 00:04:48.120 okay and so he's on site and he'll
00:04:50.480 00:04:50.490 actually look through all of this and
00:04:52.159 00:04:52.169 and decide whether or not this is
00:04:53.750 00:04:53.760 something that he can pass that's right
00:04:56.180 00:04:56.190 okay okay so on this mcdonald miller the
00:04:59.270 00:04:59.280 head if you will what are they looking
00:05:01.760 00:05:01.770 for and they're again they're looking
00:05:04.340 00:05:04.350 inside of here to make sure that there's
00:05:06.290 00:05:06.300 not an excessive buildup of scale that
00:05:09.260 00:05:09.270 could limit the float from working
00:05:11.629 00:05:11.639 properly or that could clog this line up
00:05:15.110 00:05:15.120 that could stop that line up and and
00:05:18.140 00:05:18.150 trick this thing to look like it's full
00:05:19.850 00:05:19.860 of water
00:05:20.450 00:05:20.460 okay okay obviously the man way on top
00:05:23.719 00:05:23.729 of the boiler that needs to be out as
00:05:26.330 00:05:26.340 well for yes absolutely they can
00:05:27.860 00:05:27.870 actually look down and see the tubes yes
00:05:29.990 00:05:30.000 okay yes all right so the inspector he
00:05:33.409 00:05:33.419 checks out everything everything's great
00:05:36.680 00:05:36.690 i'm assuming from there you're filling
00:05:40.550 00:05:40.560 the boiler yeah everything back well
00:05:41.930 00:05:41.940 yeah once once that's complete and you
00:05:43.730 00:05:43.740 get your clean bill you go through and
00:05:46.640 00:05:46.650 you put all new gaskets on the fire side
00:05:48.589 00:05:48.599 waterside manway put put your caps and
00:05:51.980 00:05:51.990 crosses your McDonnell Miller head back
00:05:53.719 00:05:53.729 on you button the boiler up you go ahead
00:05:56.779 00:05:56.789 and fill it up and get ready for your
00:05:59.290 00:05:59.300 test fire okay and upon that test fire
00:06:02.839 00:06:02.849 I'm assuming we're moving into the
00:06:04.279 00:06:04.289 burner and we want to make sure that
00:06:05.900 00:06:05.910 everything is it's in tune yeah it's
00:06:10.070 00:06:10.080 always a great practice once you're done
00:06:12.170 00:06:12.180 and go ahead and put a put an analyzer
00:06:14.240 00:06:14.250 on the boiler and check it and make sure
00:06:16.969 00:06:16.979 your o twos are where they need to be
00:06:18.370 00:06:18.380 make sure you have proper combustion
00:06:20.480 00:06:20.490 safeties yes absolutely we always check
00:06:24.710 00:06:24.720 your Safety's your high limits you're
00:06:27.110 00:06:27.120 running interlocks to make sure
00:06:29.089 00:06:29.099 everything is functioning so you have a
00:06:30.560 00:06:30.570 safely operated piece of equipment
00:06:33.210 00:06:33.220 so the boiler gets all started up it's
00:06:35.010 00:06:35.020 all tuned and I guess highly efficient
00:06:39.300 00:06:39.310 and really an optimal performance after
00:06:41.910 00:06:41.920 a boiler absolute affection absolutely
00:06:43.980 00:06:43.990 hi ma'am appreciate you stopping Batman

00:06:54.150 00:06:54.160 on the boiling point we appreciate
00:06:57.180 00:06:57.190 daniel stopping by and talking to us a
00:06:58.830 00:06:58.840 little bit about the open and closed
00:07:00.270 00:07:00.280 obviously that annual open and close
