摘要

在一定条件下，凝汽器压力可以看作是汽轮机的背压，它对机组功率的影响很大。基于背压计算模型，讨论了调节循环水流量对背压变化的影响。该模型是通过对冷凝器和冷却塔的机理分析建立起来的。结果表明，冷却水进口温度是计算背压时的一个重要参数。通过调节冷端系统循环冷却水流量来改变机组产量，对机组产量的增减有不同的影响。

Influence of Cooling Circulating Water Flow on Back Pressure Variation of Thermal Power Plant

Under certain conditions, condenser pressure can be considered as back pressure of the steam turbine, which has great influence on the unit power. Based on the back pressure calculation model, influence on back pressure variation by adjusting circulating water flow is discussed in this paper. The model is developed from mechanism analysis of the condenser and cooling tower. Results show that cooling water inlet temperature is an important parameter during the back pressure calculation. Changing the unit output by adjusting circulating cooling water flow of the cold-end system has different effects on the unit output increment and decrement.
