A fossil fuel power plant, known as thermal power station in Asia, or power station in the United Kingdom, is an energy conversion center that combusts fossil fuels to produce electricity, designed on a large scale for continuous operation.
This principle is then used by fossil fuel power plant converts the energy stored in fossil fuels such as coal, fuel oil, or natural gas successively into thermal energy, mechanical energy, and finally electrical energy for continuous use and distribution across a wide geographic area.
Almost all large fossil fuel power plants are steam-electric power plants, except for gas turbines and utility-sized reciprocating engines, which may run on natural gas or diesel.

 Fossil fuel power plant - Encyclopedia of Earth
A fossil fuel power plant is a system of devices for the conversion of fossil fuel energy to mechanical work or electric energy.
The gas turbine cycle relies on the Brayton cycle in which air compressed to high pressure, and heated to high temperature by the combustion of natural gas or light fuel oil, is the working fluid that expands in the turbine to provide the torque for driving both a compressor and the electric generator.
Coal gasification produces a fuel gas that is capable of being used in the gas turbine.

 Serious Megawatts - Solar Thermal Power in India
India's power sector has a total installed capacity of approximately 102,000 MW of which 60% is coal-based, 25% hydro, and the balance gas and nuclear-based.
Power shortages are estimated at about 11% of total energy and 15% of peak capacity requirements and are likely to increase in the coming years.
Demonstrating the solar plant's operational viability under Indian conditions is expected to result in follow-up investments by the private sector both in the manufacture of the solar field components and in larger solar stations within India.

 Welcome to West Virginia Coal   (Site not responding. Last check: 2007-09-18)
Although current plans call for the plant to be designed and built over the next five years, then operated for at least five years beyond that, the department envisions the project serving as a test bed for new technologies for well into the coming decade and perhaps beyond.
The plant would be sized to generate approximately 275 megawatts of electricity, roughly equivalent to an average mid-size coal-fired power plant.
Finally, the department said, the prototype plant would be a stepping stone toward a future coal-fired power plant that not only would be emission-free but would operate at unprecedented fuel efficiencies.

 Ford Foundation: Nuclear Power Issues and Choices - 391
Fuel is removed from a reactor every year or so to prevent these products from building up in it.
The fuel may consist of natural uranium containing 0.7 percent fissile uranium-235 and 99.3 percent nonfissile uranium-238, or "enriched" uranium (which has been enhanced in its concentration of uranium-235), or uranium-233 (produced earlier by conversion of thorium-232), or plutonium-239 (produced earlier by conversion of uranium-238), or some combination of these.
To take advantage of this, all commercial power reactors now operating contain a moderating material which slows the speed of neutrons released in fission, by a factor of about 10,000, to the energy at which they approach thermal equilibrium with their surroundings.

 Talk:Fossil fuel power plant - Wikipedia, the free encyclopedia
Gas turbines and reciprocating engines can be fossil fueled and they are not steam-electric (reciprocating engine power plants usually aren't very big, they range from 1 kw to about 20 MW).
For thermal power plants, a cold startup is a startup that takes place after the power plant has been shut down for at least 48 to 72 hours (the exact number of hours varies from one reference source to another).
A hot startup is a startup that takes place after the power plant has been down less than 2 to 48 hours (again the exact number of hours varies from one source to another).

 Power Plant Would Reuse Carbon Dioxide - New York Times
Subsidiaries of BP and Edison International said yesterday that they were planning to build a power plant that would run on oil residues, and that 90 percent of the carbon dioxide would be captured and pumped into an oil field, where it would help push more oil to the surface.
The $1 billion plant would be adjacent to a BP refinery in Carson, Calif., about 20 miles south of Los Angeles, and would be the first such plant in the country, the companies said.
When coal or other fuels are gasified, conventional pollutants like sulfur and carbon dioxide, which is believed to be responsible for climate change, can be removed before combustion, while the volume of gas is still relatively small.

 The Challenges Facing Hydroelectric Power   (Site not responding. Last check: 2007-09-18)
Hydroelectric plants significantly alter the landscape, or riverscape, around them, changes that cause new chemical and physical processes to occur, invariably disrupting the original environment.
It is important to note that this calculation is heavily dependent on the life span of the hydroelectric power plant since most of the gaseous emissions of a reservoir occur in its first few years of operation, and then gradually taper off as the inundated biomass decays.
(McCully, 1996) Run of river power plants (those without a large storage reservoir) are especially hard hit by this effect because sediment has less of a chance to settle out before entering their power streams.
