How does auxiliary cooling water work?

The auxiliary cooling water then proceeds to small heat exchangers used for cooling the pump and motor bearing frames, mechanical seals and other equipment. The fluid pumped from auxiliary cooling water pumps is clean, high-quality water, unlike the main cooling system, which takes water directly from the cooling tower or other sources.

How do thermal power plants circulate water?

Open Cycle and Closed cycle Circulating Water Systems in Thermal Power Plants. All thermal power plants, be they coal fired or nuclear, use the modified Rankine steam cycle. The steam exiting from the steam turbine condenses in a condenser and then is reused in the steam cycle.

Do thermal power plants use open cycle and closed cycle water systems?

Open Cycle and Closed cycle Circulating Water Systems in Thermal Power Plants. Open Cycle and Closed cycle Circulating Water Systems in Thermal Power Plants. All thermal power plants, be they coal fired or nuclear, use the modified Rankine steam cycle.

Why is cooling water necessary in a power plant?

Cooling water is required not only to cool the main condenser, but also to cool various heat exchangers in the plant, such as the main generator coolers, generator stator coolers, compressor intercoolers, various pump and fan bearing oil coolers, HVAC chillers, etc.

What type of condenser does a thermal power plant use?

Almost all thermal power plants use a surface condenser for cooling the steam. The only exception is in a geothermal plant where a direct contact condenser is used. In a surface condenser, the steam flows over a tube bundle. The condenser cooling water flows through the inside of these tubes.
