Fired power plants are fossil fuel power plants that burn fossil fuels like coal, natural gas, or petroleum to produce electricity. Fired power plant, fossil fuels are designed for large scale production takes place continuously. In many countries, this type of power plants produce most of the electrical energy used.
Fired power plant, fossil fuels have always been rotating machine that converts heat from combustion into mechanical energy which then operates the electric generators. The main driving force is probably the steam, compressed gases, or a machine cycle of internal combustion engines.
Byproduct of combustion engines must be considered in the design of machines and operations. The heat is wasted because of the limited efficiency of the energy cycle, when not recovered as a room heater, will be discharged into the atmosphere. Residual gas combustion products discharged into the atmosphere, containing carbon dioxide and water vapor, also other substances such as nitrogen, nitrogen dioxide, sulfur dioxide, and light gray (especially coal) and possibly mercury. Solid ash from coal combustion should also be discarded, although the current solid ash coal combustion can be recycled as building materials.
Fired power plant, fossil fuels are the main peyumbang greenhouse gases and contribute enormously to global warming. Coal produces greenhouse gases at least three times more than natural gas.
