Summary: The generation of power from waste heat in cement plants was for a long time the subject of controversial discussion. Today, hardly anyone remains unconvinced by the concept. Depending on the system used, 30-45 kWh/t clinker can be generated, which is up to 30 % of the electrical power requirement of a cement plant. The benefits of this technology are clear.
In cement plant, about 90% of total energy is used as heat energy in the clinker calcination process. Out of total heat consumed in the clinker calcination process, more than 35% of heat is discharged as waste heat to the surroundings without utilization. Therefore, a great deal of energy is wasted, and the heat pollution in the workplace is serious.
