Energy audit is a technique used to evaluate the thermal energy performance of the pyroprocessing unit in cement plant. Thermal energy audit in cement plant allows reduction of specific energy consumption and also optimizing the process. For this purpose, waste heat in process should be minimized. Thermal energy audit operation is performed by effort to balance total energy input with its output. In new studies, additional methods for more energy conservation on basis of thermal energy audit are investigated. A good example for this saving opportunity is waste heat recovery from kiln exhaust gases and cooler discharge gas. The results shown that the kiln and cooler exhaust gases are the major sources of thermal energy losses, amounting to 23.81% and 14.72%, respectively. Waste heat recovery from two streams output for power generation has been investigated. WHRSG can recover waste heat and produce super heated vapor for generation of 6 MW of electricity, which could lead to annual power savings of 4.32 * 104 MWh\year..<\div>

Although the very well established and favorite theories of Fuzzy Sets and Sheaves have been developed and studied independently, Ulrich H¨ohle shows that a large part of fuzzy set theory is in fact a subfield of sheaf theory. Many authors have studied mathematical structures, in particular, algebraic structures, in both categories of these generalized (multi)sets. Using H¨ohle’s idea, we show that for a (universal) algebra A, the set of fuzzy algebras over A and the set of subalgebras of the constant sheaf of algebras over A are order isomorphic. Then, we study the fuzzy version of the important, very useful, and favorite structure of acts over a fuzzy semigroup, so to say, with its internal as well as external definitions. Moreover extension principle, which enables us to extend every (universal) algebraic operation on an algebra A to an operation on the fuzzy subsets of A, is one of the most important tools in fuzzy set theory and fuzzy algebras. So we study the extension principle for the categoryof fuzzy S–acts<\div>
