What is A Steam Turbine?

According to Wikepedia, steam turbine is a mechanical device that extracts heat energy from pressurize steam converts into the mechanical motion. 86% of electric generation in the world is using steam turbine. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam. A turbine contains dozens of louvers or angled blades mounted to a central shaft. The turbine output shaft is connected to a massive generator. The wheels and shaft begin to rotate at high speed when the dry super heated steam ported into the turbine. Meaning that its depend on heat source (boiler) to change the water into super heated steam. Manjung Power Plant is using burning coal in generate or produce power.
