Condensate storage

When the condenser hotwell level reaches the high point, a dump valve opens to drain excess condensate from the hotwell to a condensate storage tank. When loss of condensate from the turbine cycle is reflected in a low level in the hotwell, a make-up valve opens in the storage tank to supply make-up water to the condenser hotwell.

Challenge

Proper functioning of the liquid level control in the condensate storage tank ensures the proper supply of make-up water.
