A combinedcycle power plant uses both a gas and a steam turbine together to produce up to 50% more electricity from the same fuel than a traditional simplecycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. Tour a combined cycle power plant.

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 ...

2. Process description of a coalfired power plant. A coalfired power plant burns coal to produce electricity. In a typical coalfired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

Like any thermal power station, we generate electricity from steam. Our entire process can be simplified into four main steps: Fuel is burned to create heat. By using finely pulverized coal, efficient combustion is assured and high temperatures are achieved. The heat is applied to demineralized water inside the boiler, turning it into steam.

These designs are popularly associated with nuclear power plants. However, this association is misleading, as the same kind of cooling towers are often used at large coalfired power plants and some geothermal plants as well. The steam turbine is what necessitates the cooling tower. Conversely, not all nuclear power plants have cooling towers ...
