Steam turbine power plants refer to the energy stations that uses the steam turbine as the prime mover and by converting steam heat energy into mechanical energy to drive the alternator to operate to generate electric energy and heat energy. This type of power station is widely used in fields such as thermal power generation and nuclear power generation, and is an important component of modern power systems.
Its basic production process is as following: Fuel burns to heat water in a boiler to generate steam, whereby the chemical energy of the fuel is converted into heat; then the turbine is driven by steam pressure to rotate, whereby the heat energy is converted into mechanical energy. Then the steam turbine drives the alternator to rotate, converting the mechanical energy into electrical energy.
Classification of Steam Turbine Power Plants，According to the classification of fuel used, steam turbine power stations can be divided into:
1. Thermal Power Plants refer to the energy stations that use coal, oil, and natural gas as fuels to produce electric power. Including coal-fired power plant, oil fired power plants, gas power plants, etc.
■ Coal-fired power plant, It refers to an energy facility that uses coal as fuel and generates steam through combustion to drive a steam turbine for power generation. Including equipment such as boilers, steam turbine generator set, etc.
■ Oil fired power plants, This refers to an energy station that uses fuel oil (such as heavy oil, diesel, or crude oil) as fuel and generates steam by burning a boiler to drive a steam turbine to produce electricity. Due to high costs, there are fewer applications.
■ Gas Power Plants, This refers to an energy station that uses gas (such as natural gas, coal gas) as fuel and generates steam by burning a boiler to drive a steam turbine to produce electricity. It has the characteristics of high efficiency and cleanliness, accounting for about 20%.
2. Biomass power plant refers to an energy station that uses the heat energy generated by biomass combustion to produce steam and drive turbines to generate electricity.
3. Heat recovery power plants refer to the energy stations that uses various waste heat from industrial enterprises to generate electricity, including boilers, steam turbine generators, and other equipment.
4. Solar thermal power plant refers to a facility that first converts solar energy into heat energy, and then heats the working fluid through a collector to drive a steam turbine for power generation. Including heat collection devices and thermal energy storage systems. At present, commercial applications are dominated by photovoltaic power plants, while thermal power plants have a limited application range due to technical complexity and cost factors.
5. Nuclear power plant refer to facility that utilizes nuclear fission reactions to generate heat energy, which is then converted into electrical energy. Its core equipment includes reactors, steam turbines, AC generators, etc.
It should be noted that different types of turbine power stations may intersect and merge in practical applications.
Selection and configuration of power plant equipment：
1. Match the unit capacity and select the appropriate power turbine based on actual electricity demand to avoid no-load losses caused by excessive capacity.
2. By adopting distributed power generation and configuring multiple small units to operate in conjunction, partial shutdowns can be achieved during periods of low electricity consumption, which can reduce fixed costs.
As an important component of modern power systems, steam turbine power plants not only play a significant role in traditional energy utilization, but also demonstrate new vitality in the fields of new and renewable energy. The steam turbine power station is developing towards large capacity, high parameters, environmental protection, and intelligence. With the advancement of technology and the increasing demand for environmental protection, the technology and application of steam turbine power stations will continue to develop and improve.
