Re: These LGB's suffered
Definitely too much Mu water killed those boilers. Nothing will kill a boiler and plug up the returns like Mu water. Too bad they ignored it.
Finally, the boiler plugs with sludge, the LWCOs fail because of sludge.
As my old boss used to say. "you can't burn up a section with water in it"

Re: These LGB's suffered
Nice work. Hopefully the owners learned a lesson about maintenance and will retain you to care for their new equipment.

I appreciate that compliment Dan but I wouldn't have known what to do without you your books and this forum thank you.

Re: Where can I find this radiator
@Grallert, @kcopp is on the money - it's a Runtal, not ours.
@rlc311 we can definitely help you out with cast iron repalcements. Pipe centers may not be exactly the same though which could cause you some issues. If you send me your contact details to nick@castrads.com, I'll get in touch with specifics.
The closest model we have has an interaxis distance of 16 ⅔", so there'd be a bit of work to do - perhaps you could bring the steam trap down by using a close nipple above the elbow.
@Erin Holohan Haskell thanks for the recommendation.

Re: A haunted steam boiler funny story
The fix was simple install a wet return that had been removed. It only took 1 day with my helper to chase off the haunting spirits and it now is silent. You can't make this stuff up.
Re: Chimney liner
168, 000 Btu/hr input on oil boiler
125,000 on gas boiler
40,000 water heater
333,000 total input
Check a chimney chart and that is your answer but 7' at a minimum

Re: These LGB's suffered
The cause(s) of this near catastrophic had several contributing factors.
1- The boilers would constantly flood. The question was how? After we had corrected a number of issues, we had steam up and found that when the boilers cycled on pressure that there was a vacuum low enough to induce a siphon from the feed tank even though the piping was 10 feet in the air. This vacuum filled the boiler. A couple of checks for vacuum breakers took care of that.
2- The return lines were almost 100 percent plugged. Lots of cutting and piping were done to clear the returns in the boiler room.
3- There were a mass amount of leaks in the system, both steam and condensate. Most have been addressed.
4- The vac pumps that controlled flow to the feed tank were working at about 10 percent when there was water that returned. The piping has been repaired but the controls will still require rewiring.
5- Currently operation on the reset control and maintain the building at 68=70’f
6- The system MUW has been very low and the chem is maintaining PH and TDS without much effort.
7- The former MUW bills had to be massive.
8- New pads were poured as the old pads were broken up pretty well
9- From start to finish, about 6 weeks time. It was a miracle that there were two LGB13 boilers in town, that the weather held off and that we could make parts work until OEM parts show up.

Re: Where can I find this radiator
Tap on the radiator.
if is lighter and steel then its a Runtal.
If it is heavy its a Castrad.

These LGB's suffered
Take a gander at these images.
If I am correct, they were loaded with chemicals, over filled and cooked and then dry fired.
The gaskets were melted between the sections in most cases and the ignition controls were melted off and hanging
Anyone seen this before?
