Coal and oilfired process. Coal and oilfired steam power plants have steam turbines to convert the heat energy of combustion into mechanical energy, which then operates an electric generator. All plants use the steam turbine for the drop between the high pressure and temperature of the steam and the lower pressure of condensing vapor.

Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Coalfired power plants have been identified as one of the major sources of air pollutants in the power sector. Most coalfired power stations have large openair coal stockpiles, which lead to a considerable amount of fugitive dust. The construction of an indoor coal storage is known to control coal dust; however, it requires significant upfront capital. Certain power utilities, including ...

3. Coal power can create high levels of radiation. A byproduct of burning coal for power, called "coal ash," produces radiation. This ash then settles around the surrounding areas of the coal plant. According to Scientific American, a coal power plant can produce up to 100 times more radiation than a nuclear power plant.

A coal power plant works in much the same way, but instead of a nuclear reactor heating water to make steam, the heat from the burning coal powers a steam turbine. 3. Solar Power Plants . The next type of power plant we will look at is a solar power plant. This type of plant uses the suns energy to convert into electricity.

Cost implications for new coalfired power plants. Newly built coalfired power plants can be made to immediately use gasification of the coal prior to combustion. This makes it much easier to separate off the CO 2 from the exhaust fumes, making the process cheaper. This gasification process is done in new coalburning power plants such as the ...

Fossil fuel power plants generate significant amounts of CO 2 emissions into the atmosphere, which are believed to be the main cause of climate change. Among CO 2 mitigation options, carbon capture and storage is considered the only technology that can significantly reduce the emissions of CO 2 from fossil fuel combustion sources. There are mainly three technological routes for CO 2 capture ...

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
