Abstract

The present invention relates to a method for simultaneous generation of electricity and cement clinker in a cement plant comprising a kiln system (1 ), a drying means (2), separation means (3) and means (4) for generation of electricity, according to which cement raw materials are dried in the drying means (2) subject to simultaneous supply of hot gases and subsequently separated from the hot gases in the separation means (3) and directed to the kiln system via a feed duct (5). The method is characterized in that hot exhaust gases from a thermodynamic machine (6) are utilized for drying the cement raw materials. It is hereby obtained that the thermal energy in the hot exhaust gases from thermodynamic machine is utilized in expedient manner. When a generator is connected to the thermodynamic machine and the generated electricity is utilized in the cement plant, the energy consumption per tonne of cement clinker will, for raw materials with a high moisture content, be reduced relative to a situation where the cement raw materials are dried by different methods. Hence the emission of CO2 from the cement plant per tonne of cement clinker will also be reduced.
