: Hi Dan! Yep---I know what you are saying about pulling teeth trying to get info outta people. However, this guy could be burning coal...which I have done....some of them don't have LWCO's. Sometimes, if you are carrying a heavy load, the water level will drop out of sight, but usually....no, it doesn't...not unless the blowdown valves leak by....and even then....it takes a bit of time. If your boiler trips off the line....you go and look at it right away, or as soon as you get another one started....it's just not normal for the water level to go out of sight low....I've had plenty of Boilers trip on me, and the only time I had that happpen was when I had a real hot fire burning on the grates with big load burning coal. Most likely, I would say this guy is having a problem with his feewater system when he takes swings. I had one situation where the DA Tank was only sized for one Boiler....they had two boilers, and everything was just peachy until they took a swing. Who knows....we don't know the whole scenario....you are definitley right about that. :)
: Oh, I just have a freindly disagreement about your comment that the water level will not drop out of the sight glass when a boiler trips. Depending on the boiler and if the firing rate was pretty decent (above low fire), it infact will most likely drop out of the sight glass, unless you work on a huge utility boiler with a steam drum the size of montana:) If you don't believe me, go hit your burner stop and then look at you sight glass. Come on I dare ya:) Some people may not be happy with you but just say it was a little experiment.
