Power plants use coal to generate electricity, because coal power is stable, reliable, and has a short construction period, which is an inevitable process of industrial development.
The principle of this method is to generate high-pressure steam from the water in the boiler, and the steam impinges on the turbine blades to rotate to drive the generator to generate electricity. generator) conversion process.
In China, coal used for power generation accounts for more than 1/3, and the average coal consumption is 370 g/(kW·h). Power plants convert the calorific value of coal into thermal energy for electricity.
