Superheated steam

Superheated steam is the designation for the water vapor which has been brought to a higher temperature than the boiling temperature corresponding to the pressure. As the working fluid so that it has a temperature of 300 to 600 ° C.

Superheated steam heated by a superheater, directly or after its removal from the production process in the boiler further, without increasing the pressure. The higher the temperature, the greater the efficiency of the process.

If the steam generated directly out of the water for the operation of steam turbines, it is called steam. The labor process and removed in an intermediate superheater steam heated again is usually called intermediate vapor.

Superheated steam for steam locomotives

With steam locomotives in 1896 led the first time Wilhelm Schmidt and Robert Garbe superheated steam at the Prussian State Railways a by giving the construction of two experimental locomotives of the Prussian S 3 with the fire tube superheater according to Schmidt-type in order. The two locomotives were delivered in 1898. In their testing, the following advantages of the hot steam showed:

Because of these advantages, the superheated steam was able to prevail worldwide in steam locomotives.

Further use

It is used in modern times as the vapors ( soil disinfection ).
