your question is not at all clear. i've never heard of a stack of industerial boilers. are you thinking about air you're blowing into, or out of, a boiler? which you would do, to make whatever is inside burn faster/hotter, by providing more oxygen.
Typically such a fan is used during startup or periods of heavy load, to supplement the induced draft.
a fan inside of a steam system would only be a simple drier, or condenser? kinda removing some of the h2o parts by colliding them together or something? steam is moist, so it is wet even though its a gas, so where i went wrong in my thinking is that just because the compound changes form(l,g,s) it still remains in its complex form, just the state changes? so still yes, it would remove moisture from steam, but then it would cool quickly, causing it to be pointless to even run a boiler system. is the fan to stoke the burner or inside the system? inside, i dont even know of a fan that would move steam pressure. the fan wouldnt do any good in a system, unless hmmmmmm dont know much about it. now, you could use a fan to create your draft or chimney effect to keep the gasses from filling a low space or to increase btu, but inside it? unless,hmmmmmmm(steam turbine lmao)
