Impulse Turbine

1. Principle: Impulse steam turbine refers to the steam turbine that expands only in the nozzle. In the moving blade of impulse steam turbine, the steam does not expand to do work, but only changes the flow direction.

2, features: impulse steam turbine: steam mainly expands in the nozzle, no longer expands or expands little in the moving blade, and mainly changes the flow direction, modern impulse steam turbine at all levels have a certain degree of reaction, that is, steam in the moving blade also occurs a small part of expansion, so that the steam flow gets a certain acceleration effect, but still as impulse steam turbine

Information

Impulse steam turbine is an efficient and environmentally friendly energy conversion equipment, its principle is to use high-pressure steam expansion to drive the turbine rotation, thereby converting thermal energy into mechanical energy. This kind of steam turbine is mainly composed of high-pressure steam generator, turbine and condenser in structure.

During the operation of an impulse turbine, high-pressure steam is generated in the generator and then passed through a series of pipes to the turbine, which drives the turbine to spin. The rotating motion of the turbine is converted into the required power by mechanical transmission devices such as couplings. The steam discharged by the turbine is cooled and condensed by the condenser, and finally returned to the steam generator for recycling.

Impulse turbines have many advantages. First of all, it uses high-pressure steam technology, high energy conversion efficiency, can reach more than 40% of the thermal efficiency. Secondly, impulse steam turbine exhaust gas temperature is low, environmental performance is good, can minimize the impact on the environment. In addition, impulse steam turbine has the advantages of simple structure, easy maintenance, long service life, high reliability and low cost, which makes it widely used in various industrial fields.

The use of impulse steam turbines is very wide, including power, chemical, paper, textile, steel and other industries. In the field of power, impulse steam turbines can be used as the main equipment of generator sets to provide stable power output for the power grid. In the chemical industry, impulse steam turbines can be used to compress air and drive pump equipment. In the paper, textile, steel and other industries, impulse steam turbines can be used to drive a variety of industrial machinery to improve production efficiency.

In short, impulse turbine is a very important energy conversion equipment, its high efficiency, environmental protection, reliability and other advantages make it widely used in various industrial fields.
