Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, in some steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired.
Steam, especially dry (highly superheated) steam, may be used for antimicrobial cleaning even to the levels of sterilization. Steam is a non-toxic antimicrobial agent. [ 11 ] [ 12 ]
Here, Garbe took over the sphere of "Construction of Superheated Steam Locomotives and Tenders". Inspired by the work of Wilhelm Schmidt ('Hot Steam Schmidt') from Kassel, Garbe was already in 1893 of the view that the use of superheated steam would give steam locomotives a power advantage.
Monument to Hot Steam Schmidt in Benneckenstein. Wilhelm Schmidt, known as Hot Steam Schmidt (German: Heißdampf-Schmidt) (1858–1924) was a German engineer and inventor who achieved the breakthrough in the development of superheated steam technology for steam engines.
They had plate frames, Belpaire fireboxes and Walschaerts valve gear and were delivered in two variants, with five of them using saturated steam while the rest were superheated with Schmidt type superheaters. They were all designated Class 10-2 by the CSAR, numbered in the range from 665 to 674, and entered service in March 1910.
A stationary boiler would be hooked up and feed superheated steam through the soda to boil off the water and effectively recharge the soda. [ 1 ] These locomotives were always called "soda locomotives" ( sodium carbonate ) although "caustic soda locomotives" ( sodium hydroxide ) would be a more precise description.
German G7a(TI) torpedo at the Norwegian Armed Forces Museum in Oslo. The G7a(TI) was the standard issue Kriegsmarine torpedo introduced to service in 1934. It was a steam-powered design, using a wet heater engine burning decaline, with a range of 7,500 metres (24,600 ft) at 40 knots (74 km/h; 46 mph) speed.
