Fly Ash & Moisture Condensation

[Reid2006]

Quick question:
Our plant is installing a small Fly Ash handling system. The storage bin will be located outside, and it gets quite cold here in the winter.

We are concerned about potential moisture condensation on the inside of the storage bin. As you may know, Fly Ash powder reacts quite quickly with water and solidifies.

Would anyone out there be able to tell me if moisture condensation is a big issue with cold weather fly ash handling systems? Is any form of insulation or dehumidication recommended?

This may be the wrong forum. If so, my apologies.

I think you ought to move this one in the power generation facilities engineering forum.

As long as we speak of fly ash (no lime added), in incineration plant, it is not necessary to heat trace, nor insulate the extraction lines or the silo. The hopper of the ESP should be heat traced. If no liquid water gets in contact with the fly ash, it flows well.
The situation is much different, if, for SO2/HCl control lime is added.
I have no direct experience of power plant fly ash, but I do not think it will be much different
