What is the purpose of CW?
The prime object of a circulating water (CW) system is to cool the LP turbine’s exhaust steam to convert it to condensate. Typically, the cooling water causes the steam to condense at a temperature of ∼45.4°C (113.7°F) and that creates an absolute pressure in the condenser of ∼0.1 kg cm2.
Which pumps is used in thermal power plant?
In thermal power plants, boiler feed water pumps and horizontal split type pumps are popularly used. The pumps are necessary for protection of the cooling pipe of the furnace. The pump maintains the flow in the pipe approximately at a fixed speed.
What is cw pump?
CW Pumps are Circulating Water Pumps used in Thermal Power Plants. These pumps are critical for plant operation. When these pumps don’t function effectively, the power output might have to be de-rated.
What is the purpose of a pump in a steam power plant?
A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler.
What type of cooling system is used in the large power plant?
What type of cooling system is used in the large power plants? Explanation: In large power plants cooling towers are used in the place of cooling ponds. A cooling tower is a wooden or metallic rectangular structure, with packed baffling devices.
What are the components of a steam power plant?
What are the components of a Steam Power Plant? Explanation: A Steam Power Plant has the sequence, Boiler, Turbine, Condenser, Pump.
Why are pumps needed?
Today, the pump is used for irrigation, water supply, gasoline supply, air conditioning systems, refrigeration (usually called a compressor), chemical movement, sewage movement, flood control, marine services, etc.
Which is the largest pump of power plant?
1. Bath County Pumped Storage Station, Virginia, USA, 3,003 MW capacity, completed 1985.
What is CW flow?
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.
Why do power plants need cooling towers?
The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating cooling water systems used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants, food processing plants, semi-conductor plants, and for other industrial facilities such as in …
What is boiler feed pump in thermal power plant?
Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted.
