How does a steam turbine generator work?

Principle: The steam turbine uses high temperature and high pressure steam from the boiler, sprays it through the steam nozzle, impacts the steam turbine blades, and drives the shaft to rotate together. Steam turbines have high rotation speed and power, and thermal efficiency is 25-30%. Mainly used in large thermal power plants and nuclear power plants.

A steam turbine is made of a thick steel plate in the center and arc-shaped blades on the outer edge of the steel plate. When steam is sprayed onto the blades, the turbine rotates, and the greater the speed. speed of the steam, the faster the turbine turns. A machine that uses steam to turn a turbine is called a steam turbine.

When gas flows from a high pressure space to a low pressure space, the greater the pressure difference, the greater theflow speed is high. Therefore, nozzles are used in steam turbines, so that when the superheated steam sent from the superheated tube of the water tube boiler is ejected from the nozzle, the volume begins to expand rapidly. At the same time, the pressure decreases and the speed increases. That is, the internal energy of the steam is converted into the kinetic energy of the steam in the nozzle. When steam is injected onto the blades, its kinetic energy is converted into mechanical energy for the rotation of the crankshaft.
