Comprehensive Analysis Of The CCHP Cogeneration System

In recent years, as China's economic development, energy supply issues are becoming increasingly prominent, the traditional way of energy supply and distributed energy which represented the second generation energy system combined to provide effective protection for our social economic development.CCHP system is a cogeneration system. It can accomplish the cooling, heating and power load at the same time by making use of both electrical and waste heat output created when power is generated. It can use energy resources more efficiently, and reduce the investment cost and environmental pollution. In this thesis, characteristics of technology and performances of the gas engine/turbine CCHP system both were analyzed, and the situation of LiBr absorption chiller in CCHP was studied. The energy consumption of the gas engine/turbine CCHP system was investigated, and the results show that the energy saving of gas engine/turbine CCHP system is related to the power generation efficiency and the performances of absorption chiller. The cogeneration power plant CCHP system and compared systems were studied with model of primary energy ratio in the following paper. At last, the factors on economy of CCHP cogeneration system was discussed, and the scheme selecting of the CCHP system was studied on the basis of the gray related degree analysis.
