摘要
直接空冷机组空冷风机的耗电量是影响机组经济性的主要因素之一,研究风机的经济运行具有重要意义。对直接空冷机组变工况时的风机运行问题进行了研究,分析了风机风量和凝汽器压力之间的相互变化关系,给出不同凝汽器压力下所需风量的确定方法,可为直接空冷风机的运行提供参考。
The electricity consumption of air-cooled fans is one of the main factors which influence economic performances of the direct air-cooled units. The problems of fan operations of the direct air-cooled units under variant working conditions are analyzed to optimize fan operations. The relationship between cooling air flow rate and pressure of the condenser is analyzed. The determining means of the cooling air flow rate under different pressures of the condenser are suggested.
