Pyrite Roasting Waste Heat Recovery BoilerNecessitySulfuric acid is one of the most important raw material for many industries,Website:http://www.chinawasteheatboiler.com, and a nation's sulfuric acid production indicates its industrial strength. One universal method of producing sulfuric acid is through pyrite roasting (to get SO2). Pyrite concentrates are transformed into solid oxides and gaseous sulfur dioxide at temperatures of 800 ? ~ 1000?, after which the sulfur dioxide in the roasting gas is cooled down by a waste heat recovery boiler and further processed to produce sulfuric acid.
