How can coal be converted into electricity?

By burning coal and heating water to turn it into steam, the machine ejects high-pressure steam to make the machine blades rotate (like a steam engine), and the other end of the blades is connected with wires to close the circuit;

Cutting the magnetic induction line in the magnetic field will form alternating current, so that the chemical energy of coal will be converted into electrical energy, and the same principle applies to thermal power generation.

Electric energy is not only an economical, practical, clean, easily controlled and converted energy form, but also a special product that the power department provides quality assurance for power users from three aspects: generation, supply and use (it also has some characteristics of the product, such as measurability, estimation, guarantee or improvement).

Extended data:

The electric energy used in daily life mainly comes from other forms of energy conversion, including hydropower, internal energy, atomic energy (atomic energy generation), wind energy (wind power generation), chemical energy and light energy (photovoltaic cells, solar cells, etc. ).

Electric energy can also be converted into other required energy forms and transmitted over a long distance in wired or wireless form.

At present, the installed capacity of power generation in China is 73% for coal power, 2.4% for nuclear power, 2.3% for gas power and 7.7% for others. Electrical appliances are devices that use electric energy to work. When it is connected to a power supply, it can convert electric energy into the energy we need.
