00:00:00.210 well regular maintenance should be 00:00:01.76000:00:01.770 performed daily and weekly monthly 00:00:04.16000:00:04.170 semiannual as well as annual we're going 00:00:07.09900:00:07.109 to talk today about weekly maintenance 00:00:08.87000:00:08.880 on your boiler today on the boiling 00:00:11.08900:00:11.099 point 00:00:26.40000:00:26.410 welcome to the boiling point we have a 00:00:28.84000:00:28.850 familiar face actually your last two 00:00:30.94000:00:30.950 have been with Michael Taylor and we're 00:00:32.77000:00:32.780 still talking about boiler maintenance 00:00:34.42000:00:34.430 this week we're going to talk a little 00:00:36.01000:00:36.020 bit about weekly maintenance so we're 00:00:37.69000:00:37.700 gonna get started here 00:00:38.89000:00:38.900 Mike appreciate you hanging out again 00:00:40.50900:00:40.519 and sharing all of the knowledge that 00:00:43.42000:00:43.430 you've got so we're going to start first 00:00:46.27000:00:46.280 weekly maintenance and let's start with 00:00:47.92000:00:47.930 the pilot and the main fuel valves talk 00:00:50.97900:00:50.989 about what we need to do from a weekly 00:00:52.42000:00:52.430 standpoint our weekly standpoint just 00:00:54.54900:00:54.559 need to make sure that they operate that 00:00:57.22000:00:57.230 when the you shut the bull or all feeder 00:01:00.34000:01:00.350 by breaking a limit or turn the switch 00:01:02.22900:01:02.239 off that they actually closed so you 00:01:05.32000:01:05.330 just turn the switch off to the boiler 00:01:08.31000:01:08.320 while it's running and you listen for 00:01:11.10900:01:11.119 the valves to actually make contact and 00:01:15.37000:01:15.380 close okay they will click if you've got 00:01:18.60900:01:18.619 a hydro motor valve then you can see it 00:01:21.37000:01:21.380 move but solenoid valve all you can do 00:01:24.16000:01:24.170 is listen for it I was looking at the 00:01:26.13900:01:26.149 CSD one recommendation they said RL so 00:01:29.91900:01:29.929 the word of the day is ro aur al and we 00:01:33.04000:01:33.050 both didn't have a clue what that was so 00:01:35.38000:01:35.390 I looked it up and it's actually listen 00:01:37.15000:01:37.160 so that's what you're doing is you're 00:01:38.91900:01:38.929 listening for that switch okay good and 00:01:42.52000:01:42.530 as far as the pilot the only time you 00:01:45.07000:01:45.080 can do it is when the actual boiler is 00:01:46.80900:01:46.819 starting up that's when the pilot will 00:01:49.12000:01:49.130 will energize when it's lighting a pilot 00:01:51.94000:01:51.950 but you it it's always a song about you 00:01:54.46000:01:54.470 can listen to it you can hear it 00:01:55.96000:01:55.970 actually make and break okay and if you 00:01:59.02000:01:59.030 have meters probably a good time to 00:02:01.83900:02:01.849 check out what's going on sure if your 00:02:03.91000:02:03.920 when the thing closes down you can look 00:02:06.30900:02:06.319 at your meter make sure it stopped 00:02:08.27900:02:08.289 it's gonna stop because the the gas 00:02:11.94900:02:11.959 stopped going to it okay alright so why 00:02:14.71000:02:14.720 don't we move next to the to gauge glass 00:02:17.19900:02:17.209 and what do we need to do I know this is 00:02:19.87000:02:19.880 a daily thing that you can look at but 00:02:21.49000:02:21.500 also weekly but what are we gonna do 00:02:23.53000:02:23.540 from a weekly yeah daily you're 00:02:24.91000:02:24.920 typically gonna look at it to make sure 00:02:26.47000:02:26.480 it's not leaking weekly you need to take 00:02:29.86000:02:29.870 a closer look at the glass and just make 00:02:32.08000:02:32.090 sure that it's not getting edged itching 00:02:35.70000:02:35.710 ants will have 00:02:37.73000:02:37.740 inside of it strictly from steam erosion 00:02:40.73000:02:40.740 okay and when it gets etched it'll 00:02:43.40000:02:43.410 actually get cloudy looking in the area 00:02:45.95000:02:45.960 where it's asked it won't be clear where 00:02:49.52000:02:49.530 you can see all the way through it it'll 00:02:50.84000:02:50.850 get cloudy if it gets cloudy it's etched 00:02:53.24000:02:53.250 and it's so it's getting thinned out 00:02:55.25000:02:55.260 needs to be replaced okay and so we're 00:02:57.80000:02:57.810 looking at this on it from a lower 00:02:59.30000:02:59.310 cutoff I mean that kind of what we're 00:03:01.46000:03:01.470 looking at well it doesn't affect the 00:03:03.26000:03:03.270 little water cut off but that's your 00:03:04.67000:03:04.680 visual image of how much water is in the 00:03:08.21000:03:08.220 board right so if it gets asked up you 00:03:11.60000:03:11.610 can't see it and then it could blow out 00:03:13.76000:03:13.770 and cause lots of problems with your 00:03:16.49000:03:16.500 controls with water and steam on them 00:03:18.41000:03:18.420 and right and it's a safety hazard in 00:03:21.44000:03:21.450 the boiler room as well if it's down 00:03:23.24000:03:23.250 close like this okay okay let's move on 00:03:27.02000:03:27.030 to the motors in the boiler room and 00:03:29.33000:03:29.340 this is something from a daily 00:03:30.80000:03:30.810 standpoint that you will actually get 00:03:33.20000:03:33.210 real familiar with sounds and that's 00:03:35.72000:03:35.730 pretty much what you're going to be 00:03:36.71000:03:36.720 looking for them are listening for I 00:03:38.39000:03:38.400 should say as far as the motors in the 00:03:41.15000:03:41.160 boiler room yeah for you when you're 00:03:44.18000:03:44.190 there every day you know what they sound 00:03:45.95000:03:45.960 like and so you need to actually pay 00:03:49.10000:03:49.110 attention to them because over a period 00:03:52.01000:03:52.020 of time just slow changes you won't pay 00:03:54.29000:03:54.300 any attention to it so you need to 00:03:55.52000:03:55.530 really focus on the motors you know at 00:03:57.59000:03:57.600 least weekly to make sure that they're 00:03:59.75000:03:59.760 not having some abnormal bearing noises 00:04:03.11000:04:03.120 or vibration happening on your blower 00:04:06.56000:04:06.570 motor your oil pump motor or your feed 00:04:09.35000:04:09.360 water pump motors do that that can mean 00:04:12.68000:04:12.690 that a bearing is going out and you're 00:04:14.21000:04:14.220 gonna have a failure 00:04:15.14000:04:15.150 typically a bearing noise is kind of a 00:04:16.88000:04:16.890 high squeal type or just a grinding 00:04:19.78900:04:19.799 noise a grinding noise yeah and you'll 00:04:23.45000:04:23.460 see some vibration from one as well when 00:04:26.00000:04:26.010 this burn is running you should be able 00:04:27.32000:04:27.330 to set a nickel up on stage and sit 00:04:29.48000:04:29.490 there on the cabinet okay big that motor 00:04:33.53000:04:33.540 is going out or the blower wheel is out 00:04:35.48000:04:35.490 of balance it's not going to set up 00:04:37.34000:04:37.350 there it's going to bounce it off the 00:04:38.54000:04:38.550 floor okay you set that on there I'm 00:04:40.85000:04:40.860 taking it 00:04:41.83900:04:41.849 this next one is really for low pressure 00:04:44.52900:04:44.539 boilers that were checking from a weekly 00:04:46.60900:04:46.619 standpoint but that's a low water cutoff 00:04:48.35000:04:48.360 so once you go through that like 00:04:50.11900:04:50.129 Wrightwood went over previously on high 00:04:52.27900:04:52.289 pressure bores how you blow this down 00:04:53.86900:04:53.879 every day on a low pressure bore the 00:04:56.74900:04:56.759 told only recommends that you do it once 00:04:58.96900:04:58.979 a week you don't have to do it daily so 00:05:01.27900:05:01.289 you you blow you open the valve up and 00:05:03.61900:05:03.629 blow the water out of the low water cut 00:05:06.40900:05:06.419 off until the burner shuts down that 00:05:08.41900:05:08.429 tells you that the lower cutoff is 00:05:11.20900:05:11.219 working okay and then just shut it just 00:05:14.38900:05:14.399 shut it right back soon as the burner 00:05:15.79900:05:15.809 shuts down shut it back off and your 00:05:17.71900:05:17.729 level will be right there and the burner 00:05:19.66900:05:19.679 will start back up okay well like I 00:05:22.10000:05:22.110 think a lot of times people take for 00:05:24.61900:05:24.629 granted on the burner that this thing's 00:05:26.02900:05:26.039 just gonna come on and when it's on that 00:05:28.51900:05:28.529 everything is operating correctly and we 00:05:30.98000:05:30.990 probably need to go through the burner 00:05:32.65900:05:32.669 somehow to be able to find out you know 00:05:34.85000:05:34.860 is this thing working right you know 00:05:37.36900:05:37.379 what how do we do this yeah and the main 00:05:39.52900:05:39.539 the main point with the burner the main 00:05:42.64900:05:42.659 safety point is the scanner which is 00:05:44.89900:05:44.909 looking at the flame making sure she's 00:05:46.54900:05:46.559 got a good flame while it's putting fuel 00:05:48.88900:05:48.899 in the burning of the boiler so at least 00:05:53.38900:05:53.399 weekly you need to check to make sure 00:05:54.92000:05:54.930 that scanner is working properly that it 00:05:56.95900:05:56.969 will shut the Buller down if it the 00:05:58.85000:05:58.860 flame goes out that it's not seeing a 00:06:01.00900:06:01.019 false flame signal okay and your log in 00:06:04.30900:06:04.319 that flame signal yeah you should be 00:06:06.35000:06:06.360 logging that actually daily which will 00:06:09.19900:06:09.209 be on your control tell you what your 00:06:10.81900:06:10.829 flame signal is and you log that in your 00:06:12.70900:06:12.719 logbook every day but then once a week 00:06:16.12900:06:16.139 you need to check to make sure that it 00:06:17.65900:06:17.669 actually works and shut everything down 00:06:20.48000:06:20.490 like it's supposed to when you lose a 00:06:23.01900:06:23.029 signal on some burners you can have a 00:06:25.69900:06:25.709 you've got a scanner that's out 00:06:28.38900:06:28.399 available where you can actually pull it 00:06:30.58900:06:30.599 off just put your hand over it and see 00:06:33.76900:06:33.779 if the burners shuts down it should shut 00:06:36.07900:06:36.089 down within four seconds of doing that 00:06:38.04900:06:38.059 by code and log that some burners you 00:06:42.13900:06:42.149 can't get to it so you can just shut 00:06:43.60900:06:43.619 your main gas valve off all right so you 00:06:46.51900:06:46.529 you simply just shut it off and the 00:06:49.36900:06:49.379 burner will shut down and it should do 00:06:52.30900:06:52.319 it again within four seconds 00:06:54.30900:06:54.319 because it it loses the signal so it's 00:06:56.82000:06:56.830 should go out and should fail on a 00:06:59.49900:06:59.509 flameout okay and your and your 00:07:01.38900:07:01.399 basically log in that time you know 00:07:03.33900:07:03.349 that's for sure it's done this enforcing 00:07:04.95900:07:04.969 right just make sure it does within four 00:07:06.96900:07:06.979 seconds typically it's gonna do it 00:07:09.48900:07:09.499 within two seconds but for what is the 00:07:11.95000:07:11.960 max okay while we move to the combustion 00:07:14.85900:07:14.869 management and talk a little bit about 00:07:17.15900:07:17.169 linkage first you know and what are we 00:07:19.54000:07:19.550 supposed to do with the linkage well 00:07:21.30900:07:21.319 basically you just checking the linkages 00:07:23.32000:07:23.330 to make sure that they're tight nothing 00:07:25.68900:07:25.699 has slipped that they go back to the 00:07:27.90900:07:27.919 same place which is with linkages 00:07:30.90900:07:30.919 they're gonna be closed because you've 00:07:33.30900:07:33.319 got hysteresis so when it changes 00:07:35.04900:07:35.059 direction there's always a little bit of 00:07:36.51900:07:36.529 slop 00:07:37.13900:07:37.149 which is called hysteresis so it never 00:07:39.79000:07:39.800 the great word hysteresis it never goes 00:07:42.21900:07:42.229 back to the exact same spot because the 00:07:45.62900:07:45.639 swivels swivel so that doesn't keep it 00:07:50.90900:07:50.919 exact okay and so you've got linkage 00:07:54.04000:07:54.050 obviously on some burners but then you 00:07:55.71900:07:55.729 also have linkage list burners and what 00:07:58.65900:07:58.669 are we doing from a servo sample what 00:08:00.39900:08:00.409 are we what do we check in there 00:08:01.38900:08:01.399 basically you're just checking to make 00:08:03.42900:08:03.439 sure that the boiler is modulating that 00:08:05.55900:08:05.569 you're you're going from low fire to 00:08:07.95900:08:07.969 high fire mid fire is your load changes 00:08:10.57000:08:10.580 as long as it's doing that then the 00:08:13.54000:08:13.550 system is working like it's supposed to 00:08:15.24900:08:15.259 alright next thing we're going lights or 00:08:18.18900:08:18.199 running lights and obviously something 00:08:19.95900:08:19.969 that's always lit up and I remember as a 00:08:21.79000:08:21.800 kid I felt kind of like buddy to the ALF 00:08:23.29000:08:23.300 I don't I just walk in and just start 00:08:24.67000:08:24.680 touching all the lights so why don't you 00:08:27.00900:08:27.019 go through all of the the lights for us 00:08:29.46900:08:29.479 tell us a little bit about what what we 00:08:30.69900:08:30.709 have to look for well the lights going 00:08:32.40900:08:32.419 to tell you kind of what's going on with 00:08:33.75900:08:33.769 the bowler and the burner if your limit 00:08:35.92000:08:35.930 is made then the light is on telling you 00:08:37.80900:08:37.819 that it'll typically tell you whether 00:08:39.51900:08:39.529 you're burning gas or oil and it'll tell 00:08:42.57900:08:42.589 you if there's a problem if there's a 00:08:43.75000:08:43.760 low water condition or a flame failure 00:08:46.48000:08:46.490 it's going to tell you from the lights 00:08:47.88900:08:47.899 if the lights are working that's why you 00:08:50.01900:08:50.029 need to check so it's not really the 00:08:52.09000:08:52.100 last resort you're not totally trusting 00:08:55.92900:08:55.939 the lights just you're just visual 00:08:58.99000:08:59.000 indicators quickly so you need to check 00:09:02.11000:09:02.120 them like the low water cutoff make sure 00:09:04.32900:09:04.339 that the light comes on 00:09:05.54000:09:05.550 you blow the blower down okay so you 00:09:07.79000:09:07.800 kind of putting that something happens 00:09:09.74000:09:09.750 here and make sure that the light comes 00:09:11.69000:09:11.700 on right okay 00:09:13.16000:09:13.170 I've been in a lot of boiler rooms and 00:09:15.38000:09:15.390 there's leaks all over the place whether 00:09:18.11000:09:18.120 it's water leak or some type of a steam 00:09:20.87000:09:20.880 leak of course and and we definitely 00:09:22.51900:09:22.529 don't want gas leak so why don't you go 00:09:24.71000:09:24.720 through and talk about where some leaks 00:09:26.81000:09:26.820 could be well as we talked about earlier 00:09:29.66000:09:29.670 with the gage glass that's a very good 00:09:32.03000:09:32.040 place for leaks on the gauge glass 00:09:33.86000:09:33.870 engage coughs but you can have any valve 00:09:36.35000:09:36.360 especially the packings you're gonna 00:09:38.32900:09:38.339 have to have leaks I need to regular 00:09:41.24000:09:41.250 maintenance on tightening that packing 00:09:42.86000:09:42.870 up or repacking the valves you can also 00:09:46.40000:09:46.410 have flue gas leaks from around the 00:09:49.00900:09:49.019 doors so it's a good idea 00:09:51.38000:09:51.390 you know just run your hand away from 00:09:54.29000:09:54.300 the door don't touch it because it's hot 00:09:55.97000:09:55.980 if the boiler is running and make sure 00:09:58.22000:09:58.230 there's not any air blowing out around 00:10:00.19900:10:00.209 the burner you can see the gasket 00:10:01.85000:10:01.860 material that will get old and 00:10:04.34000:10:04.350 eventually is gonna have a leak 00:10:06.07900:10:06.089 someplace so check them to make sure you 00:10:07.67000:10:07.680 don't have leaks in the ballroom okay 00:10:09.25900:10:09.269 well let's stack what same thing with 00:10:11.56900:10:11.579 the stack 00:10:12.29000:10:12.300 I mean it's open so you shouldn't have a 00:10:14.38900:10:14.399 leak there but again you got a lot of 00:10:17.66000:10:17.670 heat it heats up to us off the gasket 00:10:20.56900:10:20.579 material gets old brittle and will start 00:10:23.00000:10:23.010 leaking so you need to make sure it 00:10:24.65000:10:24.660 stays sealed up and what other places 00:10:26.59000:10:26.600 hand holds man ways sure hand hose man 00:10:30.56000:10:30.570 ways I mean even the heads on the low 00:10:33.01900:10:33.029 water cut-offs you can have steam leaks 00:10:36.53000:10:36.540 out of your controls any of that so it's 00:10:40.10000:10:40.110 I mean just visual check everything to 00:10:43.61000:10:43.620 make sure there's no leaks and first 00:10:45.01900:10:45.029 illipe fix it don't let it keep going 00:10:47.06000:10:47.070 and get worse 00:10:47.99000:10:48.000 right I think the biggest thing with the 00:10:49.61000:10:49.620 leaking part is exactly what you just 00:10:51.56000:10:51.570 said and that is as you're walking 00:10:52.93900:10:52.949 through the boiler room and there's 00:10:54.94900:10:54.959 something that's leaking get it fixed 00:10:57.31900:10:57.329 right away so yeah the longer you leave 00:10:59.84000:10:59.850 it the worse that's gonna get and it's 00:11:01.51900:11:01.529 gonna eventually if you leave a valve 00:11:03.11000:11:03.120 leaking it's gonna cut the stand before 00:11:05.21000:11:05.220 you can't fix it you gotta replace it 00:11:06.94900:11:06.959 okay well there you have it all the 00:11:09.65000:11:09.660 weekly maintenance Mike thanks for 00:11:11.09000:11:11.100 hanging out with us again today and 00:11:12.65000:11:12.660 we'll see you next time on the boiling 00:11:14.63000:11:14.640 point appreciate Michael stopping by and 00:11:17.03000:11:17.040 talking to us a little bit about weekly 00:11:18.80000:11:18.810 boiler main 00:11:19.51900:11:19.529 you know boiler equipment failures they 00:11:21.29000:11:21.300 can be dangerous and typically result in 00:11:23.03000:11:23.040 lost productivity and revenue scaling a 00:11:25.81900:11:25.829 boiler on the water side will cause 00:11:27.05000:11:27.060 overheating and thus result in a boiler 00:11:29.11900:11:29.129 failure 00:11:29.66000:11:29.670 when this occurs sometimes there can be 00:11:31.69900:11:31.709 catastrophic failures that results in a 00:11:33.53000:11:33.540 water side or fire side explosions this 00:11:35.96000:11:35.970 is more serious consequences including 00:11:37.97000:11:37.980 injuries and facility damage with the 00:11:40.79000:11:40.800 right preventative maintenance plan 00:11:41.90000:11:41.910 these issues can be avoided or greatly 00:11:44.36000:11:44.370 reduced well make sure you like us on
