Advantages of combined cycle power generation The worldwide demand for combined cycle power plant is growing dramatically, with some experts forecasting explosive growth over the next decade. In its basic form, a gas turbine exhausting into a heat recovery steam generator (HRSG) that supplies steam to a steam turbine cycle is the most efficient system of generating electricity today. Thanks to
Steam Electricity. Steam powered turbines and generators account for a majority of the electricity generated in the world today. Electricity can be generated by steam by using a steam turbine generator. The pressure of the steam acts as a force to rotate a turbine which will produce electricity inside of a generator. Steam electricity is usually produced in a steam turbine generator that is an impulse or reaction turbine.
The exhaust steam from the turbine or engine enters at the top and forced to move downward due to the suction of the air extraction pump. In this steam condenser, the cooling water enters into boiler through lower half of the tubes in one direction and returns in opposite direction through the upper half as shown in the figure above.
