What is the purpose of chemical water replenishment in power plants?

The role of chemical water make-up in power plants: optimizing the operation of the water make-up system.

There are mainly two advantages:

1. The first advantage is that if the make-up water enters the condenser throat as a spray, some of the exhaust steam will condense here. , and Reducing the amount of steam discharged to the condenser not only reduces the loss of cold sources, but also increases the condenser vacuum. Make-up water circulates through low pressure heaters at all levels with the main condensed water. , realizing step by step heating and increasing energy efficiency with low power consumption. High-energy steam extraction from the low-pressure degasser and high-pressure degasser is reduced, improving the thermal economy of the unit.

2. The second advantage is that the preliminary elimination of oxygen can be obtained in the condenser, thereby reducing the degree of oxygen corrosion of low pressure heating equipment. During operation, the temperature of the desorbed water is low and. dissolved oxygen is greater than 60ug/l.

Water used in power plants is mainly for cooling the units and dissipating heat. Water is used as a cooling fluid, and its consumption is directly related to its method of heat exchange. Water cooling methods include direct heat dissipation through cooling. towers, heat dissipation by radiators, etc., cooling Direct heat dissipation of the tower is related to climate, wind, etc., and consumes a lot of money, while closed heat dissipation consumes almost nothing.
