Cement – Analysis - IEA

The global thermal energy intensity of clinker is estimated to have fallen to about 3.4 GJ/t in 2018, representing annual average drops of 0.5% since 2014. Fossil fuels continue to provide the majority of energy in the cement sector, with bioenergy and biomass-based wastes accounting for only 3% of thermal energy used in 2018.

Reduce Energy Consumption: Cement Production

25/08/2011  A China-based cement plant used VFDs to significantly reduce its energy consumption in its dry-process kilns, responsible for production of 1.4 million tons of cement each year. Traditional damper control systems used a fixed amount of energy, so fans at the plant always ran at full capacity even when the facility wasn’t producing product—wasting energy and causing unnecessary wear on
