  1. 1. POWER PLANTS SUBRAMANYAM.P 114P5A0303
  2. 2. TYPES OF POWER PLANTS  Wind power plants (1No-1MW)  Solar power plant (1No-2MW)  Hydel-power plant (22No-42240MW)  Thermal power plant(6No-7900MW)
  3. 3.  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.
  4. 4. 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..
  5. 5. 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
  6. 6. NEED FOR THERMAL POWER GENERATION  Scarcity of water resources  Widely available alternate fuels  Maintenance and lubrication cost is lower  Coal is abundant  Working fluid
  7. 7. THERMAL POWER PLANT (STEAM POWER PLANT)
  8. 8. SCHEMATIC DIAGRAM OF THERMAL POWER PLANT
  9. 9. GENERAL LAYOUT OF THERMAL POWER PLANT
  10. 10. 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
  11. 11. 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
  12. 12. 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
  13. 13. DISADVANTAGES OF THERMAL POWER PLANT  Air pollution  Starting time & Efficiency  Transportation of fuel  Power generation cost  Requires skilled manpower  Life of the plant
  14. 14. 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.
