摘要
丰镇发电厂利用2号机组关停后闲置的低压加热器对现运行的4号机组进行系统改造,将空冷机组的循环水出水利用管道引出一部分,再将工业泵出口生水接入原低压加热器汽侧,逆向换热升温,循环水冷却后返回原空冷机组的循环水回水管道,实现对循环水冷却降温,同时关闭原专用于对生水进行加热的抽汽,减少抽汽热耗。改造后4号机组真空度提高了0.5 k Pa,节能效果显著。
Fengzhen Power Plant heaters. Drain out of a part of the carried out the reformation to the idle low pressure circulating water of air cooling unit with the pipes, then access industrial pump discharge water to the steam side of the original low pressure heaters, the reverse heat to heat up, circulating water back to the original circulating water return pipe after being cooled to realize the circulating water cooling. And close the original special extraction steam to heat water to reduce this part of the extraction steam heat loss. After transforming, unit vacuum saving result was apparent degree increased by 0.5 kPa, and the energy
