合理确定供热汽轮机热电分摊比的新方法

A New Method of Reasonably Determinating Heat Consumption Allocation Ratio on Cogeneration Steam Turbine

在研究以往供热汽轮机总热耗量热电分摊模型缺陷的基础上,根据既可从数量上评价又考虑能量质量特性的统一尺度,以热力学循环理论和供热汽轮机抽汽供热工质循环为基点,提出了合理分摊供热汽轮机热电联产总热耗量的新方法。所提出的分摊方法,推导严格、计算简捷,对供热汽轮机热力系统不需作任何人为假定和简化,计算结果真实合理,为供热汽轮机热电联产总热耗量的合理分摊提供了依据。

According to the unified dimension that can evaluate both quantitaty of energy and the property of its quality, and the theory of thermodynamic cycle and the extraction heating cycle of cogeneration steam turbine, the authors put forward a new method of reasonably determinating heat consumption allocation ratio on cogeneration steam turbine, boased on its previous research defects. The proposed allocation method in this paper is derived strictly, simple, reasonable and real, without any artificial assumption. It provides a basis for the reasonable allocation of total heat consumption on cogeneration steam turbine.
