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.
Superheater tubes Pass steam back through the boiler to dry and superheat it for greater efficiency. [2] See Superheater (32). Throttle valve (US+) Regulator valve (UK+) Controlled by the Throttle Lever / Regulator (8), regulates the amount of steam delivered to the cylinders, which is one of two ways to vary power of the engine (throttle ...
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 ...
The engine was based on that of the Class P 4.1 that had Hanomag had produced in large numbers since 1892. It had slightly larger wheels and, due to its new design, significantly fewer heating tubes. The superheater and the steam engine were entirely independent designs.
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. Wilhelm Schmidt was born in Wegeleben in the Prussian Province of Saxony on 18 February 1858.
HRSGs consist of four major components: the economizer, evaporator, superheater and water preheater [clarification needed]. The different components are put together to meet the operating requirements of the unit. See the attached illustration of a Modular HRSG General Arrangement.
In 1900, two extra engines were added to the class, Furness Railway numbers 124–125. (works numbers 4651–4652). In 1913, two engines, FR Nos. 34 and 37, were fitted with experimental Phoenix smokebox superheaters, however, these were removed the following year. At some point in time locomotives 21, 22, 34 and 35 were renumbered 44–47 ...
The rebuilt engine still retained its additional axle, resulting in a more spacious cab for the driver and fireman. The tender was not rebuilt, but was modified slightly at the front so that the ends of the curved side sheets now finished 8 feet 2 + 3 ⁄ 8 inches (2.499 m) apart; it was also given streamlined plating at the top (which was ...
