摘要

水资源的减少及分布不均问题促进了火力发电系统中空冷技术的产生，但是空冷机组也有能耗较高的缺点。凝汽器是空冷机组的核心设备，其排汽压力是影响整个系统性能的最关键指标之一。以某电厂600 MW机组为例，提出一种冷凝器背压的简便计算方法，分析了迎面风速、环境温度、凝汽流量以及污垢热阻对凝汽器排汽压力的影响，为优化空冷机组运行、节能降耗提供参考。

Abstract

The reduction and uneven distribution of water resources has promoted the generation of air-cooled technology for thermal power systems

but the energy consumption of air-cooled units is higher. Condenser is the core equipment of air-cooled units

and its exhaust pressure is one of the most important indicators affecting the performance of the whole system. Taking a 600 MW unit of a power plant as an example

a simple calculation method for the back pressure of the condenser was put forward

and the influence of upwind speed

ambient temperature

condensate flow rate and fouling thermal resistance on the exhaust pressure of the condenser was analyzed

which can provide reference for optimizing air-cooled units operation

energy saving and consumption reduction.
