摘要
在影响凝汽器真空的很多因素即循环水进水温度、机组的负荷、凝汽器的清洁度不变时,根据电厂现有的循环水泵台数,通过改变循环水流量,提高凝汽器的真空,利用低成本软件运营系统,实时计算出循环水泵的不同运行方式下机组发电综合煤耗率,并以其为最终的优化指标,来确定循环水泵的运行方式,为循环水泵的优化运行提供理论依据,也为发电厂节能降耗带来经济效益。
Many factors including circulating water inlet temperature,unit load and the cleanliness of the condenser impact the condenser vacuum,on condition that these factors are unchangeable,the condenser vacuum can be improved through changing the circulating water flow.The real time calculation of coal consumption rate under different operation mode was carried out by low-cost software operating system,according to this optimization aim,the operate mode of circulating water pumps was decided.The optimization resu...
