Analysis of Steam Engine topics include: Steam power plant and its efficiency, rankine and brayton cycle, mean temperature of heat, steam reheating, regeneration, feed water reheaters and deaerator. A steam engine is a heat engine that uses steam to perform mechanical work. The engine works by burning fuel, usually coal, to heat water in a boiler. The steam produced from the heated water is then directed through pipes to a cylinder. The steam pressure in the cylinder moves a piston, which performs mechanical work in the machine.  The steam engine's pushing force can be transformed into... Show more
