Why a combined cycle power plant? The simple reason efficiency. When compared to a traditional coal or gas fired plant (boiler or simple cycle combustion turbine), a combined cycle plant's overall efficiency can be 20 30% greater. This means that fuel use is 20 30% less and the fuel cost per megawatthour is 20 30% lower.

In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.

Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...
