Circulating Water Requirements in a Thermal Power

The Thermal power plant water steam cycle requires the steam to condense in a condenser. This requires an enormous quantity of water, known as Circulating Water. This affects the condenser vacuum which is the most important performance parameter in a power plant How much quantity of circulating water is required in a thermal power plant. This article briefly answers this.
