Chapter 3 provides an overview of the cement production process and an overview of main environmental matters in the cement industry. It describes the main sub-processes involved in cement production and defines the group of sub-processes which is to be covered by the BAT Reference Document for the cement sector.
Power Generation by Waste Heat Recovery in Cement Industry
Cement production is an energy intensive industrial process that requires heat to be supplied at high temperature levels under the constraints of gas-solid heat exchange phenomena and the kinetics of chemical reactions. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago.
