What is the principle of a thermal power plant?

Use fuel to generate heat and heat water to form superheated steam at high temperature and high pressure. Then the steam enters the steam turbine along the pipe and continues to expand and do work. It has an impact on the turbine rotor and. rotates at high speed, causing the generator rotor to rotate (electromagnetic field), and the stator coil cuts the magnetic lines of force. Electrical power is generated and then the step-up transformer is used to step up the voltage to the system voltage. , which is then connected to the network and transmitted outside. Finally, the cooled steam is further boosted by the feed water pump and returned to the boiler to repeat the above cycle process.

Thermal power generation is a method of generating electricity that uses thermal energy generated when combustible materialsThey are burned and convert it into electrical energy via an electricity production device. China is rich in coal resources. In 1990, it produced 1.09 billion tonnes of coal, of which only 12% was used for electricity generation. Thermal energy production still has enormous potential.

Detailed information:

< p>The production of thermal energy results in many other by-products and produces numerous environmental impacts. According to the principle of the Carnot cycle, there always remains a part of the waste heat which must be discharged into the atmosphere via cooling towers or cooled by bodies of water such as natural rivers. Flue gases after burning fossil fuels will be emitted into the atmosphere. Its main components are carbon dioxide, water vapor and other components suchs as nitrogen, nitrogen oxides, sulfur oxides, etc. If it's a coal-fired power plant, there will be some as well. be pulverized coal, mercury, etc. The residue after coal combustion also needs to be removed from the boiler, and part can be recycled to make construction materials.

Baidu Encyclopedia Thermal Power Generation

The working principle of thermal power generators is the conversion of energy from plants that use coal, oil and natural resources. gas as fuel to produce electrical energy.

In the generator, clean air is filtered by the air filter and high pressure atomized diesel is injected from the injector. The two gases are fully mixed in the cylinder and the piston moves. The movement compresses the mixed gas, causing a decrease in volume and an increase in temperature.nature.

Once the temperature reaches a certain temperature, the diesel ignites and the gas mixture burns violently, causing the volume to expand, thus pushing the piston down. The diesel engine uses this principle to operate the generator and convert diesel energy into electrical energy.

Presentation of the thermal power plant:

Thermal power plant A thermal power plant, called a thermal power plant, is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Its basic production process is as follows: When fuel is burned, water is heated to generate steam, which converts the chemical energy of the fuel into thermal energy. The steam pressure causes the steam turbine to rotate and the thermal energy is converted into mechanical energy. Then the steam turbine drivesthe rotating generator, converting mechanical energy into electrical energy.

The main engine is usually a steam engine or gas turbine. In some smaller power plants, an internal combustion engine may also be used. They all use high temperature and high pressure steam or gas to pass through. The pressure drop during the process of converting the turbine into low pressure air or condensed water generates electricity.
