In a steam engine, the superheater further heats the steam generated by the boiler, increasing its thermal energy and decreasing the likelihood that it will condense inside the engine. [1] [2] Superheaters increase the thermal efficiency of the steam engine, and have been widely adopted. Steam which has been superheated is known as superheated ...
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 ...
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 ...
On leaving the superheater, the steam exits the dry header of the superheater and passes down a steam pipe, entering the steam chests adjacent to the cylinders of a reciprocating engine. Inside each steam chest is a sliding valve that distributes the steam via ports that connect the steam chest to the ends of the cylinder space.
Diagramatic section through an earlier steam locomotive boiler and firebox to the right. Note the boiler is not fitted with a superheater. In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel ...
[citation needed] This technology had a substantial influence on the development of the steam locomotive and steamship, as well as all other applications where steam engines were used. Schmidt also invented other items, such as the superheater (around 1890) and the piston valve , which he developed together with Robert Garbe of the Prussian ...
The superheater was placed in the gap formed between these, with both ends of its tubes connected to a single superheater header drum, and an internal baffle to separate wet and dry steam. [10] A secondary effect of the superheater was to increase the temperature differential between inner and outer tubes of the bank, thus encouraging circulation.
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. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
