A steam separator, sometimes referred to as a moisture separator, 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. 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 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. ==Sources== * (Nuclear Encyclopedia article ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「steam separator」の詳細全文を読む スポンサード リンク
