What are the advantages and disadvantages of galvanized steel heat exchanger? I am generating flue gases through pyrolysis process. Can I pass the flue gases through galvanized steel heat exchanger to heat water?
I presume you mean galvanized steel. Galvanizing would be a waste of time for flue gas. Carbonic acid ( CO2 + water) would dissolve/corrode the zinc. Sulfurous acid could be present causing even faster corrosion. Generally flue gases are a challenge for corrosion control.
