Cleaning sections on caked on silt.

Parker

I have a 100 hear old apartment  dbuilding with a HBsmith 525 kbtu boiler. This winter one section cracked and when they took it abart there was a very hard caked on sediment blocking the bottom of the sections. The repair guy says that one of my returns must be sucking in dirt. Anyway can these sections be cleaned as this stuff is hard as rock. I was thinking high pressure water cleaning, or is there a solvent i can use. i am also thinking if they cannot be cleaned of replacing with 2 - 250kbtu Weil mcclain units.

any thoughts

you might just replace all the sections, and you will have a 60% new boiler. most important, if you replace the whole boiler, double check that the original was sized properly to begin with [details in "the lost art of steam heating" from the store.--nbc

you should replace the returns...using a chemical cleaner is just going to loosen more dirt and your problem will never end! Also ...i doubt you will ever get the boiler unclogged to the point of where it can actually work even half way efficiently again....sounds like you're due for a major overhaul.
