The Thermal Economics' Analysis Of Gas Steam Combined Cycle And Its Combined Cooling, Heating And Power

This paper sets out from the engineering of combined cooling,heating and power,the usage establishment is in the standpoint of the thermal economics that its foundation is Exergy analysis, taking the whole system of the gas steam combined cycle and its combined cooling, heating and power as the research object, making a systemic, thorough economical study for it.In the text, first introduce the constitute, principle and characteristics of the cchp system which is a comprehensive energy system; in the following, overview the domestic development and the research situations of outside in this realm; immediately after, introduce in brief the research object's engineering general situation and the design projects that be brought up aimed at this engineering in this text; then detailed discuss a kind of lately thermal economics cost absorption method- the method of share the cost of the product's Exergy according to the ability class, and make use of this method and the product Exergy equivalence method and steam equivalence method to carry economics analysis to the design project respectively,and carry on the economy compared for the calculation of the several kind different cost absorption method from the point of view that the price of the energy Exergy.This text introduce the method of share the cost of the product's Exergy according to the ability class into the study of the cchp system elementary, contact Exergy cost with the energy quality of the product organically, clearly give the cost absorption equation of the method of share the cost according to the ability class, and apply in the engineering practice, give the cchp system a thermal economics analysis completely, incarnate equitable economical principle of settling the price according to the quality, make the analytical result of the thermal economics have science and rationalities, provide the basis and path for the further studying and discussing.
