Steam from the LP turbines will be condensed in condenser using seawater in a once through cooling system. The condensate will be pumped from the condenser hot will through the gland steam condenser and low pressure heaters to raise its temperature before entering the deaerator. The hot condensate will be pumped from the deaerator by turbine driven boiler feed pumps through high pressure feed heaters and the boiler economizer into the boiler drum.

In the boiler drum steam will be separated from the remaining water which will be further circulated in the boiler to generate steam. The steam will flow from the boiler drum to the superheater to raise its temperature to the level required for the HP turbine. Steam temperature will be controlled by means of spray water desuperheaters.

TThe main steam supply leaving the superheater at high temperature and pressure will enter the HP turbine through governor valves which control the quantity of steam supplied. After transferring energy to the HP turbine most of the steam will be returned to another section of the boiler for reheating to the high temperature required for the IP turbine. The reheated steam will enter the IP turbine, pass on to the LP turbines via the cross over pipes and finally be exhausted to the condenser. The power produced by the generator will be supplied to the EGAT 500 KV grid via isolated phase bus ducts, the generator transformer and the station switchyard.
