A method is proposed to calculate the chemical exergy with allowance for the chemical composition and the ambient temperature. The exergy analysis of cement clinker burning is performed. It is found that the maximal energy saving for a rotary cement kiln can be achieved by decreasing the sludge humidity and optimizing the fuel combustion and the clinker cooler operation. The analysis of

Exergy and its Applications. Exergy analysis is an approach used by engineers to address the aspects of energy use or energy transformation that are governed by the second law of thermodynamics. While the first law of thermodynamics implies that heat and work are both forms of energy transfer, the second law implies that they are not equivalent.
