Huaneng Yuhuan Power Plant will continuously build four million kilowatt ultra-supercritical steam turbine-generator sets.
The first unit is expected to be put into operation in 2007. The rated power of a single unit is 950,000 kilowatts, and the maximum output is 6.5438+0.06 million kilowatts. All technical parameters of the unit are the highest in China, and it is also in a leading position in the world.
Extended data:
Thermal power plant, referred to as thermal power plant, is a factory that uses coal, oil and natural gas as fuel to produce electric energy. Its basic production process is: fuel burns hot water in a boiler to generate steam,
Chemical energy of fuel is converted into heat energy, steam pressure drives turbine to rotate, heat energy is converted into mechanical energy, and then turbine drives generator to rotate, and mechanical energy is converted into electrical energy.
Firepower refers to burning coal to generate electricity, and thermoelectric refers to burning coal or oil or natural gas for industry or heating. Nowadays, in order to improve efficiency and save energy, power generation and heating are generally combined.
Part of the gas is pumped out for heating at a certain stage of the gas turbine, and the rest is still rushed to the gas turbine.
Drive the generator to generate electricity, and the two can be adjusted, which can supply more heat and generate less electricity, or supply less heat and generate more electricity. At present, under the influence of energy policy, China is vigorously developing nuclear power (Guangdong Daya Bay) and hydropower (Three Gorges and Yangtze River), which can also provide heat. In order to save energy, some countries have wind power generation and geothermal power generation, while China has few. That is to say, thermal power plants are mainly used to generate electricity.
Thermal power plants mainly provide heat energy, and can also be by-products of thermal power plants.
