Steam turbine is a kind of rotary steam power plant. High temperature and high pressure steam passes through a fixed nozzle to become accelerated airflow and then is injected onto the blades to rotate the rotor equipped with blade rows while doing work externally. Steam turbine is the main equipment of modern thermal power plant, and is also used in metallurgical industry, chemical industry and ship power equipments.
In industrial production, steam turbines are directly used as prime movers to drive some large mechanical equipment, such as large fans, feed water pump compressors and other equipment with relatively high power. Steam turbines for this purpose are called industrial steam turbines(nowadays some industrial steam turbine are also used in paper mill, sugar refinery for the purpose of generation and heat supply). Steam turbines that drive pumps, blowers, compressors and other machinery or steam turbines for power generation that are closely related to industrial production processes. Industrial steam turbines can not only use fuel or steam generated in boilers by-product heat energy in various industrial production processes, but also use residual steam in production processes.
