节能调度条件下确定热电联产机组供电煤耗的探讨

Determination of Power-supplying Coal Consumption of Cogeneration Units under Energy-saving Dispatch

针对节能调度需要根据并网机组的实际供电标准煤耗进行排序的问题,对带供热火电机组的供电煤耗计算方式进行了探讨,通过对目前常用的热量法和方法的对比分析,以及对热量的生产、转换和使用过程的分析,指出方法是探求供电煤耗的科学方法。

As grid-connected units under energy-saving dispatch need to be sequenced according to the actual standard coal consumption for power supply, the calculating method for power-supplying coal consumption of heat and power cogeneration units is approached. Through comparative analysis of common thermal means and exergy method together with the investigation into the heat generation, conversion and utilization process, it is indicated that the exergy method is a scientific approach to the determination of power-supplying coal consumption.
