摘要(Abstract)：

以某亚临界纯凝汽式330 MW机组为例进行了供热方案的设计计算,阐述了基于"以热定电"的设计思路和"保电供热"的运行需求之间的矛盾,分析了不同供热改造方案的供热能力以及对机组性能的影响,对凝汽式机组通过供热改造满足当地用热需求方式提出了合理性的建议。
This paper carries out the design calculations for the heat supply scheme of a subcritical 330 MW condensing unit and elaborates the contradiction between the design according to "power generation based on heat demand" and the operational demand for "heat generation ensuring power supply".Through the analysis of the capacities in heat supply in different retrofit schemes and the influences on unit performance,it brings forward reasonable proposals for condensing units to meet local heat demand through heat supply retrofit.
