  • POWER BOILER AIR EMISSION COMPLIANCE WITH NEW …

    Sep 29, 2021 · SO 2 is formed during the combustion of coal. The amount of SO 2 produced depends on the sulfur content of the coal burned in a boiler. FGD scrubbers remove the SO 2 from a boiler's post-combustion exhaust (flue gas) by passing it through an alkaline solution. This process is also effective in removing acid gases, such as hydrochloric acid.Learn More
