Steam power plant Behavior is a power plant that uses steam turbine as a prototype steam generator spinning at high temperature and pressure from changing the status of water in boiler. When it receives heat from the combustion of the fuel in the furnace (Furnace), the steam is sent to drive steam turbines, which have a shaft connected to the generator, and after that it will go through, condensing into water at (Condenser), condenser and returned to receive new heating boiler because the nonperformance.Can change the State of the water vapor quickly. When started, each time until the works will take about 2 – 3 hours, so it is suitable to be used as a power plant base (Base Load Plant), which continue to produce electrical energy at all times for long periods before stopping the machine each time. Typically, steam power plant is approximately 1 – 1,300 MW. Can use several types of fuel such as coal. Oil furnace Natural gas, garbage, etc. and about 30 35% efficient – and have a lifespan of about 25 years.Critical components, boiler (Boiler) is a device that acts from different types of fuel, energy, heat energy, m.d. backpacks in the form of water vapour pressure and high temperatures. The boiler is differ according to applications such as Fire – Tube Boiler is boiler size, little used to produce steam with pressure and temperature is very high Water Tube Boiler is a boiler – large steam production with high temperature and pressure, typically exist 2 is a DRUM which can produce steam at a pressure of up to 177 atmospheric pressure (Bar 179) and the Once-Through steam which can be produced at low pressure and high pressure water crisis than (Critical Pressure) atmospheric pressure is 220 (220.5 Bar).The boiler is important system is the fuel system. System, combustion Economizer, Evaporator, Superheater Separater Drum or Air Heater, Fan and props.Steam turbine (Steam Turbine) are of various sizes, ranging from small (smaller than 1 MW) – Single Cylinder, Non – Type Reheat until large (larger than 1,000 megawatts), Multi-Cylinder Type Reheat. Steam turbines are important components Control Valve, Stop Valve, is the Stator, Rotor Blade, Blade Casing and Rotor with other necessary accessories such as Feed Water Pump and Heating Plant, – rotating condensed (Condenser), etc.
