Close-up. Electricity Generation and Related CO2 Emissions. Electricity is essential for industry, buildings and all aspects of daily life. But it has to be generated from a primary energy source, such as coal, natural gas, uranium, the sun, wind or water.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
Improvements to heat rate are one means to reduce the emissions of carbon dioxide (CO 2) from coal-fired power plants. Heat rate is the amount of heat input from fuel per unit of net power output. Because heat rate is the inverse of efficiency, a lower heat rate .
The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 % on an HHV basis that is the normal range for a well-optimized power plant. Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %.

Coal-fired Power Plants in Thailand 1.1 Coal-Fired Power Plant Development in Thailand 1) Brief Review of Thailand's Energy Status Figure 1-1 shows how the electricity output in Thailand from 1971 to 2014 has been growing, especially starting from the late 1980s. Of the power sources available, Thailand highly depends on natural gas and coal.
The power industry's trusted source for generation technology, O&M, and legal & regulatory news for coal, gas, nuclear, hydro, wind & solar power plants; power jobs
A coal-fired power station is a type of fossil fuel power station.The coal is usually pulverized and then burned in a furnace with a boiler.The furnace heat converts boiler water to steam, which is then used to spin turbines which turn generators.Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy.
The function of the coal fired thermal power plant is to convert the energy available in the coal to Electricity. Coal power plants work by using several steps to convert stored energy in coal to usable electricity that we find in our home that powers our lights, computers, and sometimes, back into heat .

Investigation of Thermal Integration in a Coal-Fired Power Plant with MEA Post-Combustion Carbon Capture by Erony Whyte Martin A Thesis Presented to the Graduate and Research Committee
A coal-fired power plant burns coal to produce electricity. In a typical coal-fired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.
