The condenser is a device which is used to convert the steam back to the liquid phase. A multiple pass shell and tube heat exchanger is used to maximize the amount of heat transfer with water from the cooling tower. The water circulated from the cooling tower returns to the cooling tower to be atmospherically cooled. The liquid formed from the steam, the condensate is then recyled back to the back into the boiler feedwater stream. It should be noted that during the condensation process a number of gases become dissolved in the condensate. These dissolved gases are treated by the deareator.
