A steam locomotive from East Germany. This class of engine was built in 1942–1950 and operated until 1988. A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder.
Back pressure turbines are available in single stage or multi-stage options. Primarily, this kind of turbine is used as a reducing station between boiler unit and the process steam header. Back pressure turbines are commonly employed in industrial plants where a large quantity of steam is required. Their straight-back pressure nature makes them useful in

A steam turbine is a rotating machine that converts the energy of the steam (by virtue of its pressure and temperature) into the mechanical energy of the rotor. For this purpose, the pressure energy of the steam is converted into kinetic energy and then it is utilized to move the moving blades that are mounted onto the rotor of the turbine.
As its name suggests, a steam turbine is powered by the energy in hot, gaseous steam—and works like a cross between a wind
