The analysis of mass and energy balances of a typical rotary kiln cement plant is performed in this paper. The objectives are to evaluate the mass and energy balances in the cement plant, in order to determine the overall energy efficiency of the process and to enable their recovery by installing an ORC plant cogeneration system. 2.
Mass and Energy Balances. One of the fundamental laws of physics states that mass can neither be produced nor destroyed---that is, mass is conserved. Equally fundamental is the law of conservation of energy. Although energy can change in form, it can not be created or destroyed. These two laws of physics provide the basis for two tools which ...
