rusty steam boiler

freddrow

9 month old 4 section weil mclain commercial oil fired steam boiler with very rusty water? the old boiler was removed because it was very under sized. now that the new boiler is in the water is very rusty. it was installed with one supply to the header as the direction stated. it has both hartford loop and equalizer. after boiler was installed it was skimmed of all oils and squick was added to help clean it up. now 9 months later the water is getting very dirty. the digital water feeder says 117 gallons have been taken on, but that is with start up fill and several drain and flushes. the system was just gone thourgh to insure no vents where leaking and eveything was good. what gives? where do i go from here? should i pipe a second supply to the header?

thanks for any help

dirty boiler

It's not the boiler, it's the system. The new boiler is making steam a lot faster than the old one did and it's cleaning up the system. All that crud and rust and whatever else is coming back to the boiler. It can take some time to get it clean again, and some never do. If you can, reset the feeder everytime you do a flush and clean to track consumption. A leak will add fresh water and keep the corrosion process going.

Check with the mfg on cleaning agents

depending on the crud in the system.

You have to clean, clean, clean and clean.

Most have you use TSP or similar agent.
