Cement Kiln Process Modeling to Achieve Energy

2016-1-1  Cement manufacturing is an energy-intensive and heavy pollutant emissions process. Waste-derived alternative fuels are widely used to reduce the pollutant emissions and the use of fossil fuel. Within the cement kiln, it requires about 40–50% of total thermal energy to complete the complex chemical reactions of clinker formation.
