3. Nuclear power plant: nuclear energy is converted into electrical energy;
Specific process: nuclear energy - internal energy - mechanical energy - electrical energy
The thermal energy production process is a procedure that converts the chemical energy generated during combustion of fuels (such as coal) into electrical energy. According to their functions, they can be divided into two categories, namely vapor condensing type and thermoelectric type. The first only provides electrical energy to users, whilethat thermoelectricity not only provides electrical energy to users, but also provides thermal energy such as steam and hot water to users, which is called "heat and power cogeneration ". Thermal power plants have different capacities and different specific shapes, but their production processes are similar.
The nuclear reaction in the nuclear reactor produces thermal energy--->The thermal energy is heated by water to produce steam at high pressure---> The high pressure steam drives the turbine to rotate through the pipe--->The rotation of the turbine drives the generator to rotate and produce electricity.
The high pressure steam is then cooled by water, or recycled, or supplied with heating water. for residents in winter, or directly discharged.
However, hydroelectric plants use energygravitational potential force formed by the height required to produce electricity.
