Dry Hydrated Lime Injection For Coal

When coal is oxidized burned as fuel the elemental sulfur it contains is converted to SO 2 Some of this SO 2 is converted to SO 3 when oxygen leftover from the combustion process causes further oxidization in the boiler A system equipped with a selective catalytic reducer SCR to reduce NO X emissions will convert additional SO 2 to SO 3...
