摘要
朗肯循环理论光凭一条下界限饱和线不便表达回热加热循环过程。本文提出了液压熵的概念,试图建立朗肯微循环理论,藉以描述超高参数下运行的热电厂中构成回热加热循环的每台设备的运行工况,以便对热力循环系统实行全面的监控。此外,还以水的物理特性参数表作为液压熵的实验依据,对液压熵的存在性进行了验证。
Since the Rankine cycle theory based only on a lower saturation boundary line cannot well express a heat-recovery heating cycle, a hydraulic entropy concept is presented in this paper in an attempt to establish a Rankine microcyc(?)e theory for describing the operation status of each equipment of the heat-recovery heating cycle in a heating and power plant operating under superhigh parameters, so that the whole thermal cycle system can be monitored in an all-round way. The paper also verifies the exist(?)nce of the hydraulic entropy using the water physical characteristic parameters table as experimental basis for the hydraulic entropy.
