When the condenser hot well liquid level reaches a high point, the drain valve opens to drain excess condensate from the hot well to the condensate storage tank. As condensate is lost from the turbine cycle, the hot well level is lowered and the storage tank replenishes the condenser hot well.

Challenge:

The normal operation of the liquid level control in the condensate storage tank can ensure the normal supply of make-up water, so as to ensure the normal operation of the whole plant, so it is very important to choose the correct instrument for indication and control.
