600MW Thermal Power Unit Heat recovery systems analysis model
Abstract
China is an energy-rich but energy level is also an urgent need to improve the country. power generation business is the major energy consumption. The level of their energy level direct impact on the country's energy situation. Relations with the country's environmental quality,also generating enterprises for sustainable development an important link. With the development of the times， thermal power generation uses large capacity and supercritical technology, which is an effective way to improve the economic units. China also makes supercritical unit as one of the key points to the construction of thermal power units in a period of the future. 600 MW thermal power units is the main part of supercritical thermal power units, for an important part of 600 MW thermal power units-- heat recovery system, the analysis of heat recovery system plays an important role of improving the thermal efficiency, saving energy and the stability of the system. This paper introduces the characteristic and main process of production for 600 MW thermal power units. The entire thermal system of thermal power units is described exhaustively and the paper focuses on the regenerative system. Several methods for the hot efficient target analysis of thermoelectric power station are described in detail. And the establishment of a heat recovery system of calculation model of economic indicators and analysis of small indicators. Finally, examples prove the veracity and reliability of heat recovery systems analysis model of thermal power units, which has already been established. Power Unit for the thermal system to provide thermal efficiency of the evaluation method.
