DAN HELP! I have four year old firetubes being replaced.I can still see the manufacturer's writing on them!
I work for a school, we have four Burham 250s. Looks like a lot of damage is being done during layup. Currently we do a wet layup. I increase sulfides to 100+ ppm and periodically circulate by means of a pump installed between the blowdown and a topside port. I know we have "in season" chemical issues which we are working to correct, however, My first step starts now. I am going to go to a dry layup. I've drained and flushed 2 boilers,opened the manhole, and side ports and placed a fan on the manhole to dry out the interior surfaces. I have clay desiccant to keep them dry inside after I close it back up. Is clay desiccant acceptable,preferred, or is quick lime or Silica gel or something else better?
I am commited to do what it takes to get things corrected
I've just learned of this website and I'm very impressed with the good information passed back and forth. It is now in my favorites list.
