摘　　要：为降低能源消耗,可采用工业汽轮机作为原动机拖动高耗能机械设备。分析热电厂现有热力系统,进行驱动汽轮机选型、参数确定,以中温中压蒸汽为动力源,拖动热网循环水泵,并将乏汽用于热网低压加热器。该热网改造方案,能够减少热网循环水泵耗电量,实现电厂能源梯级利用,节能效果显著。In order to reduce energy consumption,industrial steam turbines can be used as prime movers to drive high energy consuming machinery and equipment.Based on the analysis of the existing thermal system of the thermal power plant,the model selection and parameter determination of the drive steam turbine are carried out.The circulating water pump of the heat network is driven by the medium temperature and pressure steam as the power source,and the steam is used in the low pressure heater of the heat network.This scheme can reduce the power consumption of circulating water pump,and realize cascade utilization of power plant energy,and save energy significantly.
