Electricity generation begins by focusing on the boiler. The boiler feedwater is preheated by the heat exhchanger referred to as the economizer. The boiler uses the feedwater to generate steam. The steam that is generated by the boiler would damage a turbine used to generate electricity. In order to prevent turbine damage, the steam must be raised to a temperature above its corresponing pressure. This eliminates the harmful moisture content in the steam. The superheated steam is utilized to spin the blades of the turbine. The electricity generated by the turbine is usually on the order of 10-18MW. This is then sent to a transformer which boosts the voltage of the electricity to allow it to be fed into the power grid. All of the remaining superheated steam is then sent to a condenser. The condenser causes the steam to return to the liquid phase. The liquid is then sent to the cooling tower where it comes into contact with the air and is cooled. In order to recycle the water to the boiler, the condensed water is sent to a water treatment system.
