What chemicals are added to the circulating cooling water of thermal power plants and what are their

Chlorine and scale inhibitors are added to circulating water in power plants to inhibit the growth of microorganisms in the water and prevent water scaling.

The formation of organic attachments in the circulating cooling water system is mainly caused by the growth of microorganisms, because the mucus released by the microorganisms during their growth and their reproduction will become a mediator, removing silt and plant debris in the water sticks in the cooling water channel. The primary method of preventing organic attachments from forming in copper condenser tubes is to kill microorganisms in the cooling water so that they lose their ability to adhere to the tube wall. The main way to kill microorganisms is to add fungicides. Since there are many types of microorganisms growingt in circulating cooling water, the problem of sterilizing cooling water is relatively complex. Based on overall considerations such as circulating water quality characteristics and fungicide price, the commonly used sterilization treatment method in large thermal power plants is to add liquid chlorine or sodium hypochlorite . Some power plants also use organic amine fungicides intermittently to prevent microorganisms. Commonly used fungicides create resistance and enhance the bactericidal effect of the system.

The coal arrives from outside the factory and goes directly into the coal hopper of the boiler through a belt, or it is stored in the coal yard through a belt, then from coal park to the boiler through the belt. . Of course, there must be equipment such asiron extractors, large block extractors and coal crushers along the way. The coal in the coal hopper of the boiler goes through the coal feeder, the coal crusher (the fluidized bed boiler does not have a coal crusher and directly burns the coal), the coarse powder separator and between into the furnace for combustion (if it is an intermediate storage pulverization system, the coarse powder After the separator, it must pass through the fine powder separator to the pulverized coal bunker, and the coal pulverized will enter the oven to be burned via the coal feeder).

The water comes from the chemical water production workshop and is brought to the degasser or condenser. From the condenser through the condensate pump, mechanical seal heater, low pressure heater, to the deaerator, then via the high pressure heater to the boiler economizer, thewater wall, the steam drum (DC boiler does not have a steam drum), superheater to The high pressure cylinder of the steam turbine finishes its work and then returns to the boiler heater for heating. It then goes to the medium and low pressure cylinders of the steam turbine, then to the condenser for cooling. a complete cycle.
