CFD for Cement Industry
Cement Production involves calcination of Raw meal generated by Coal or petcoke Combustion in Kiln and Calciner. The Conversion of raw meal to Clinker happens in “Pyro Section”. Almost 60% of the Calcination of raw meal is completed in Calciner and the remaining in long, rotating, horizontal Kiln. The raw meal is preheated in a series of Preheated Cyclone before Calcination. The hot clinker is cooled in air coolers, crushed in crushers to fine particle size.
Calcination of raw meal can be expressed as
CaCO3———–> CaO+ CO2 Endothermic Reaction
The heat required for calcination is supplied by combustion of Primary fuels like Coal, Petcoke, Tyres or Alternative fuels. Due to high temperature, thermal NOx is produced. Side product of Calcination is Carbon dioxide
It is highly energy intensive process and produces large quantities of gaseous pollutants like Carbon dioxide, Sulphur dioxide and Nitrogen Oxides. Reduction in energy consumption and reducing pollutant formation is a key Challenge for Cement Industry.
