摘要:

分析了供热机组与纯凝机组的差异及冷端优化的注意事项。供热机组的冷端优化应按照采暖季和非采暖季分别考虑。采暖季热耗受背压影响非常小,应按照非采暖季的气象条件、冷端配置、机组运行时间等条件确定机组的设计背压。

Abstract:

The difference between heat supply unit and full condensing unit is analyzed.Advice is provided for cold end optimization.Cold end optimization of the heat supply unit shall consider heating season and non-heating seasons repectively.The influence of backpressure on heat consumption during heating season is less,so the designed backpressure shall be determined based on the climate conditions of non-heating seasons,cold end arrangement and running time of the unit.
Co-generation of heat and power; Heat supply unit; Designed backpressure
