The magical science of power plants. A single large power plant can generate enough electricity (about 2 gigawatts, 2,000 megawatts, or 2,000,000,000 watts) to supply a couple of hundred thousand homes, and that's the same amount of power you could make with about 1000 large wind turbines working flat out. But the splendid science behind this amazing trick has less to do with the power plant ...
As this diagram shows, the plant operates on the same principles as other fossilfueled electric generating plants—it burns coal to produce heat that turns water into steam, which then turns turbines in a generator. Sources/Usage: Public Domain. Credit: Georgia Power
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.

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.

Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy ). They essentially work the same as a coal or nuclear power plant, the main difference being the heat source. With geothermal, the Earth's heat replaces the boiler of a coal plant or the reactor of a nuclear ...

The dimensions and operating conditions used for this simulation do not represent any specific coalfired power plant. This model is for demonstration and tutorial purposes only. Before looking at the model, it may be useful to look at the process flow diagram (PFD). SCPC Power Plant (simplified description) Inputs: Throttle valve opening,
(d) Excludes the energy of the coal and natural gas to the power plant. (e) Includes the coal and natural gas fed to the power plant since these resources are consumed within the boundaries of the system. Because the energy in the coal is greater than the energy delivered as electricity, the life cycle efficiency is negative.
High Durability.

Natural gas power plants are cheap and quick to build. They also have very high thermodynamic efficiencies compared to other power plants. Burning of natural gas produces fewer pollutants like NOx, SOx and particulate matter than coal and oil. [2] On the other hand, natural gas plants have significantly higher emissions than a nuclear power plant.
An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.

Producing sustainable clean energy is one of the key challenges in modern power generation systems. Coalfired power plants are one of the main sources of electrical energy due to the low cost of coal compared to other fossil fuels. However, one of the major problems of the coalfired power plant is the exhaust emission of fine particulate matter.
Coal is the main source of electricity generation in fossil fuel based power plants. The use of coal in coalfired power plant (CFPP) causes raise in global temperature due to greenhouse gases emission responsible for global warming across the globe [1, 2]. It also has an adverse impact on the health of human being.
