Closed Cooling Water System In Power Plant

The application of hofmann hfm in the closed circulating cooling water system of coal fired power plant units is a good example of engineering samples in huaneng jinggangshan power plant.

Closed cooling water system in power plant.

Failure of a closed system has the potential to shut down a portion if not all of the plant. P rimary cooling at steam generating power plants and many other heavy industries is a critical aspect of operation and upsets can cost a great deal in lost efficiency and production. The rest is then sent back to the condenser in the power plant. Since the sea is a free and large open source of water we see many power plants located on the seacoast.

Wet recirculating or closed loop systems reuse cooling water in a second cycle rather than immediately discharging it back to the original water source. In chemical plants for example in caustic soda production water is needed in bulk quantity for. Ji an city located in central area of jiangxi province is one of the three pillars of jiangxi culture and is the cradle of chinese revolution. In an open circulating water system water from a large water body like the sea or a river or a lake is pumped to the condenser and is returned back to the same source.

Closed systems are also widely used in air conditioning chilled water systems to transfer the refrigerant cooling to air washers in which the air is chilled. Most commonly wet recirculating systems use cooling towers to expose water to ambient air. K this is direct dry cooling using air cooled condenser acc and the only nuclear power plant where it is in routine use is for the very small. Other closed recirculating cooling applications include smelt spout cooling systems on kraft recovery boilers and lubricating oil and sample coolers in power plants.

The whole power plant then uses less than 10 of the water required for a wet cooled plant j but some power around 1 1 5 of the power station s output is consumed by the large fans required. A circulating water plant or circulating water system is an arrangement of flow of water in fossil fuel power station chemical plants and in oil refineries the system is required because various industrial process plants uses heat exchanger and also for active fire protection measures. But often overlooked are auxiliary closed cooling water ccw systems which also serve vital functions.
