Steam Energy: Usage and Potential Name Institution Introduction For generations, steam turbine power generators have been used to generate electric power. In its conventional form, burning fossil fuels such as oil, coal or natural gas are normally used to heat water.
Numerous applications utilizing a generator for the production of electrical power were formed on this basis. This is the same principle of electromagnetism that works for in a spinning turbine. Combine Cycle gas Turbine Power Plant also referred to as a gas-fired combined cycle power plant is a system that combines the capabilities of two different thermal processes in a unique way. The two thermal processes that are combined include a steam turbine together with the gas turbine to produce electricity. Normally, CCGT is the acronym that is used to describe this kind of system (Doty, 2009). In this system, close to a third of the power generated is electrical energy. This is achieved by combusting a mixture of compressed air and fuel. A generator coupled with the hot gases created in the combustion process drives the turbine. The remaining one third of the generated electrical power is produced by the steam turbine through the utilization of the hot exhaust gases that leave the gas turbine. The exhaust gases in the heat recovery steam generator (the HRSG) transfer their heat into water that is circulating. In the process, the pressure in the system rises due to the vaporizing pressurized water. The steam turbine is driven by the steam coupled by a generator. Combine Cycle gas Turbine Power Plant are technologically advance and are nowadays used all over the world. ...
