Magnesium Oxide powder (Caustic Calcined Magnesia) is calcined from raw magnesite at arround 900℃. Due to high acititvity, it is suitable to use for Flue Gas Desulfurization. 

Fuels burn will produce sulfur oxides, which is harmful both to the plant efficiency and the environment. 

Spaying of Magnesium Oxide powde for immediate neutralization of SO3 and partially SO2.
