Energy-saving transformation of closed-loop cooling water system for mother-tube controlled cogeneration units
In response to the problems in closed-loop cooling water system of main-pipe scheme combined heat and power generation units,an energy-saving transformation of the closed-loop cooling water system was conducted.By keeping the flow rate constant while reducing the head of closed-loop cooling water pump impeller through cutting,the closed-loop cooling water systems of four units were interconnected.The closed-loop cooling water system operates in a big main-pipe scheme,and under non-summer conditions,one water pump operation can be reduced.After the implementation of the energy-saving transformation,not only did it improve the safety of the system operation,but also achieved good economic benefits.
