供水温度对高背压热电联产系统能耗水平的影响
Impacts of water supply temperature on energy consumption of high back pressure cogeneration system
摘要
Abstract
Heat supply is effective to improve the overall efficiency and reduce the coal consumption rate in air-cooled power plants. A key issue about design optimization of cogeneration system is to determine the optimal values of the designed primary network water supply temperature,based on the performance variation of overrall system resulting from the temperature of supply water in the primary network. The heat transfer efficiency and energy consumption were analyzed for different design parameters,i. e. heating load and primary side water supply temperature. The heating characteristics under off-design conditions were discussed with the mechanism modeling and Ebsilon platform. Results showed that design value of primary side water supply temperature had significant effect on system heat transfer efficiency and energy consumption. The variation of coal rate was 4.56g/kW·h due to the change of primary side water supply temperature.关键词
