Alternative Fuels in Cement Manufacturing IntechOpenCement kiln Wikipedia

Cement production involves the heating calcining and sintering of blended and ground raw materials typically limestone CaCO 3 and other materials containing calcium silicon oxides aluminium and iron oxides to form clinker Clinker production takes place at material temperatures of about 176 C in either rotary or shaft kilnsHigher SO 2 emissions by rotary kiln systems in the cement industry are often attributable to the sulfides contained in the raw material which become oxidised to form SO 2 at the temperatures between 370 176 C and 420 176 C prevailing in the kiln preheater Most of the sulfides are pyrite or marcasite contained in the raw
