Combined cycle power plant how it works. A combined-cycle 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 simple-cycle 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.
A combined cooling, heating and power CCHP system can achieve up to 50 greater system efficiency compared with a CHP plant of the same size. A simple tri-generation system consists of four main units, as shown in Figure 2.5. The main part of the system is the power generation unit, also known as the prime mover, which produces mechanical power.
Figure Schematic diagram of a Thermal power plant. Selection of site for thermal power plant Nearness to the load centre The power plant should be as near as possible to the load centre to the centre of load .So that the transmission cost and losses are minimum. This factor is most important when Dc supply system is adopted.

geothermal power plant diagram 2. Liquid-dominated geothermal power plant. In the liquid dominated reservoir, the water temperature is above the normal boiling point 100 degrees C. However, it does not boil but it remains in a liquid state because the water in the reservoir is under pressure.
Modern power plants have an extensive electrical distribution system to provide reliable power to all of the support equipment in the power plant. The utility operating the power plant is in the business of generating electrical power twenty four hours a day, seven days a week. Since electrical power can not be economically stored the plants ...
High head power plants When the operating head of water exceeds 70 meters, the plant is known as High head power plant. Pelton wheel turbine is the prime mover used. Medium head power plants When the water ranges from 15 to 70 meters, then the power plant is known as a Medium head power plant. It uses Francis Turbine.
Simplified diagram of a biomass power plant trees enter on the left into the woodchipper, woodchips are burned to heat the boiler, the high-pressure steam then drives a turbine which spins a generator to make electricity. The seedlings are planted over 16,000 hectares of plantations to grow for 5 to 8 years to mature into trees.
Jun 16, 2014 A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. Rankine cycle Coal is used as a fuel to heat water in a coal based thermal power plant.
