There are two ways to produce electricity from water
1. This method is more common among lay people. It is a hydroelectric power station. The hydroelectric plant first stores the water, so that the water has some mechanical energy. When the valve is opened to release the water, the water above flows to the other side of the dam in a certain channel. The water turbine is rotated and the water turbine further drives the generator. The water initially present. Mechanical energy is converted into electrical energy via a water turbine.
2. This method is commonly used in the field of thermal and nuclear energy. Take the example of thermal energy. Let's first talk about the main energy conversion in thermal power plants. Basically, the chemical energy of coal is converted into mechanical energy and the mechanical energy is converted into electrical energy.
Then, the main way to cTo convert the chemical energy of coal into mechanical energy is to send the pulverized coal into the furnace for combustion. Obviously, burning coal alone can only produce heat. be sent to the boiler for heating (the flue gas produced by burning coal is used to heat the water in the pipe), so that the water heated by the boiler turns into steam and is steam saturated dry. This steam has a certain kinetic energy, and is then sent from the pipe to the steam turbine to do work, and the rotating steam turbine drives the power generation machine to realize the conversion of mechanical energy into electrical energy .
