Steam Separator
A steam separator, sometimes referred to as a moisture separator or steam drier, is a device for separating water droplets from steam. The simplest type of steam separator is the steam dome on a steam locomotive. Stationary boilers and nuclear reactors may have more complex devices which impart a "spin" to the steam so that water droplets are thrown outwards by centrifugal force and collected. All separators require steam traps to collect the water droplets that they remove. It is important to remove water droplets from steam because: * In all engines, wet steam reduces the thermal efficiency * In piston engines, water can accumulate in the cylinders and cause a Hydrolock, hydraulic lock which will damage the engine * In thermal power stations, water droplets in high velocity steam coming from nozzles (or vanes) in a steam turbine can impinge on and erode turbine internals such as turbine blades. * In other steam-using industrial machinery, water can accumulate in piping and caus ...

Steam Dome
The steam dome is a vessel fitted to the top of the boiler of a steam engine 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 .... It contains the opening to the main steam pipe and its purpose is to allow this opening to be kept well above the water level in the boiler. This arrangement acts as a simple steam separator and minimises the risk that water will be carried over to the Cylinder (locomotive), cylinders where it might cause a Hydrolock, hydraulic lock, also known as Priming (steam locomotive), priming. A steam dome should not be confused with a Sandbox (locomotive), sand dome. Railway locomotives The first locomotive with a deliberate dome added to the boiler barrel was Stephenson's 'Phoenix' an 0-2-2 for the Liverpool and Manchester Railway in 1830. Many other locomoti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
