    • POWER PLANTS SUBRAMANYAM.P 114P5A0303
    • TYPES OF POWER PLANTS  Wind power plants (1No-1MW)  Solar power plant (1No-2MW)  Hydel-power plant (22No-42240MW)  Thermal power plant(6No-7900MW)
    •  The installed capacity of APGENCO on 31.07.2012 is 8924.9 MW. Comprising 5092.5 MW Thermal, 3829.4 MW Hydro, 2 MW Wind power stations and 1 MW solar power.  It contributes about half the total Energy Requirement of AP.  APGENCO is third largest power generating utility in the Country next to NTPC & MAHAGENCO. It installed a Hydro capacity of 3664.4 MW and is the second highest among the Country.
    • INTRODUCTION With the world on a development , there is shortage of power in most places while the demand seems to be in a never ending . There are several answers to this challenge such as the nuclear power plants, but the conventional thermal power plants also play an equally important role in this power generation..
    • CLASSIFICATION THERMAL POWER PLANTS ARE CLASSIFIED BY THE TYPE OF FUEL AND THE TYPE OF PRIME MOVER INSTALLED            By fuel Nuclear power plants Fossil fuelled power plants Biomass fuelled power plants Solar thermal By prime mover Steam turbine Gas turbine Combined cycle Reciprocating engines Micro turbines , stirling engine
    • NEED FOR THERMAL POWER GENERATION  Scarcity of water resources  Widely available alternate fuels  Maintenance and lubrication cost is lower  Coal is abundant  Working fluid
    • THERMAL POWER PLANT (STEAM POWER PLANT)
    • SCHEMATIC DIAGRAM OF THERMAL POWER PLANT
    • GENERAL LAYOUT OF THERMAL POWER PLANT
    • The layout of steam power plant is shown in the above figure. It consist of four main circuits they are: 1.Coal and Ash circuit 2.Air and flue gas circuit 3.Water and Steam circuit & 4.Cooling water circuit
    • DETAILED PROCESS OF POWER GENERATION IN A THERMAL POWER PLANT:  Water intake  Boiler heating  Steam Turbine  Generator  Special mountings  Ash collection system  Other monitoring instruments
    • ADVANTAGES OF THERMAL POWER PLANTS  Initial cost & Fuel  Less space & can be Install at any place  Cost of generation  Maintenances and lubrication cost  Nature's mercy  construction and commission time
    • DISADVANTAGES OF THERMAL POWER PLANT  Air pollution  Starting time & Efficiency  Transportation of fuel  Power generation cost  Requires skilled manpower  Life of the plant
    • FUTURE PROSPECTS  Accelerating the Development of CO2 Capture and Storage Technology is the Key to Realize Next-generation Power Generation System.  Preventive Maintenance Technologies that Support the Long-term, Stable Operation Facilities and Extension of the Service Life of High-temperature Gas Turbine Parts.
