ABSTRACT:
The present invention is directed to a method of controlling the condensation of sulfur trioxide in flue gases to thereby inhibit the corrosion of metallic parts because of the sulfuric acid inherently formed. Basically, the method provides for the addition of particulate ammonium carbonates to the flue gas at a place where it is experiencing turbulence, and where its temperature is below 950.degree. F. and preferably in the range of 250.degree. F. to 450.degree. F.
