汽机热泵联合系统的提出及经济性初探

The Proposition and Economic Primary Exploration of Combined Turbine and Heat Pump System

通过减温减压器的热力学分析,得出蒸汽中约20%的高品质能量经过减温减压器后被浪费。基于能量梯级利用原理,提出了汽机热泵联合(combined turbine and heat pump,简称CTHP)循环系统,并从供热量、能源利用率与电厂收益三方面证明了系统的优越性。

Through the thermodynamic analysis to the temperature and pressure reducer,the authors get the result that about20%of the high quality energy of the steam is wasted after the temperature and pressure reducer.Based on the principle of energy cascade utilization,the combined turbine and heat pump(short for CTHP)system is put forward and the superiority of the system is proved from the heat supply,energy use rate and profits of power plant.
