热电厂热电分摊实际焓降法的新算法

摘要

本文在传统实际焓降法的理论基础之上,结合现代大型热电联产机组的现状,考虑了供热回水对主蒸汽在汽轮机中实际焓降的影响,建立了一种专门针对现代大型再热式热电联产机组的热电分摊方法.通过典型的应用算例,对比了传统实际焓降法和文中新方法的计算结果,得出新方法的成果更具有实际意义,物理意义也明确、合理,更适合现代热电联产机组大型化、综合化的理论需求.%Based on the traditional enthalpy drop method, combining the present situation of modern large reheat cogeneration units, and considered the backwater in influence of the main steam actual enthalpy drop in steam turbine, this paper set up a cost allocation method of modern large reheat cogeneration units. Through the typical example, compared with the results of traditional actual enthalpy drop method and this new method, the results of the new method is more practical,physical meaning is also clear and reasonable, and is more suitable for modern cogeneration units.
