摘　　要：越来越多的城市郊区电厂改造成为热电厂。针对热网电厂运行中存在热网循环水加热不足、选择热网汽侧疏水注入系统的位置、热网回水管道补水标准的选择、热网除氧器的正常运行、热网循环水泵的调速运行和热网疏水泵的调速运行等方面的问题,进行了分析,并提出了措施。A growing number of city suburbs power plant transformed into thermal-power plant.In view of the problems in the operation of the heating network,including inadequate circulating water heating of heating network,the location choice of steam side drainage inlet system in heating network,the choice of the replenishment standards of heating network return pipe,the normal operation of the deaerator for the heating network,the speed control of the circulating pump and the speed control operation issues of heat supply network drain pump,etc.have been analyzed and countermeasures have been put forward in the paper.
