Thermal power generation is thermal power generation by combustion of fuel (coal, petroleum and its procts, natural gas, etc.) are obtained. Thermal power generating units, there are two main forms: the use of high temperature and high pressure steam boiler steam turbine driven rotary impulse generator, called the Turbine; fuel into the gas turbine thermal energy directly into mechanical energy to drive a generator for power generation, known as gas turbine power generation unit. Usually refers to the power plant turbine generator-based power plants.
Thermal power plant consists of four key components, namely boilers, turbines, condenser, generator. Fuel combustion chemical energy is converted to heat water in the boiler is heated into steam, and steam driven turbine acting thermal energy, thermal energy into mechanical energy and electrical energy into mechanical energy generator, thus completing the entire power generation process.
Hydropower
Hydropower is the height of a river or lake, river) through the gap formed downstream of diversion leads to push the rotating turbine driven generator. In hydro power plants group known as hydroelectric plants.
Hydroelectric power plant performance by reservoir regulation can be divided into:
① Radial hydropower plant: no reservoir, basically to how much electricity a hydropower plant water hair;
② Japanese Adjustable hydropower plant: a small reservoir, regulating reservoir for a day and night cycle, day and night will be a natural flow through reservoir regulation of hydropower generation;
③ Adjustable hydropower plant in: natural runoff within a year of each month to optimize distribution, regulation, the wet into the reservoir of excess water, turn on the water to ensure the dry season hydropower generation.
④ Adjustable hydropower plant for many years: the natural inflow for many years to optimize the uneven distribution, regulation, large multi - year regulating reservoir capacity, the excess amount of water stored in reservoirs wet years, dry years the water shortage supplement to ensure Adjustable output power plants.
Nuclear power
Nuclear power is the use of the atomic reactor fuel (such as uranium) fission slowly release heat to generate steam (instead of the power plant boiler) and then drive steam turbine driven generator rotating power. In nuclear power plants mainly known as nuclear power plants, referred to as nuclear power plants. Depending on the type of nuclear reactors, nuclear power plants can be divided into type PWR, BWR-type, gas-cooled reactor type, CANDU type, fast breeder reactor type and the like.
Wind power
Use of wind blowing on the top of the tower built in large blades rotating wind driven generator called by a few blocks, a dozen or even dozens of seats composed of wind turbine power generation site called wind farms.
Other new energy
Such as geothermal power plants, tidal power plants, solar power plants.
