Introduction to power plants

  1. 1. Introduction to Power Plants
  2. 2.  Power plants are set up to meet electricity requirements of any nation.  Power is generated from various sources like wind energy, hydro energy, solar energy, heat energy and nuclear energy.  Accordingly, in India there are hydroelectric power stations, nuclear power stations, thermal power stations, solar thermal power stations.
  3. 3. Out of total electricity consumed in India  65.34% is generated by thermal power plants  21.53% is generated by hydroelectric power plants  2.70% by nuclear power plants &  10.42% by Renewable Energy Sources. More than 50% of India's commercial energy demand is met through the country's vast coal reserves.
  4. 4. Thermal Power Plant- Definition  A power-generating plant which uses heat to produce energy is called thermal power plant.  Such plants may burn fossil fuels or use nuclear energy to produce the necessary thermal energy.  In a thermal power plant, the energy stored in fuels such as coal, natural gas, and fuel oil is sequentially converted into electrical energy.
  5. 5. Current installed capacity of Thermal Power as of June 30, 2011 is 115649.48 MW (65.34% of total installed capacity)  Coal Based Thermal Power produces 96,743.38 MW (54.66% of total installed capacity)  Gas Based Thermal Power produces 17,706.35 MW (10.00% of total installed capacity)  Oil Based Thermal Power produces 1,199.75 MW (0.67% of total installed capacity) The state of Maharashtra is the largest producer of thermal power in the country.
  6. 6. Thermal Power stations in India
  7. 7. Power Plants in Gujarat  Ukai TPS (850 MW)  Gandhinagar TPS(870)  Wanakbori TPS (1470 MW)  Sikka TPS (240 MW)  Dhuvaran TPS (220 MW)  Kutch Lignite Power Plant (290 MW)  Surat Lignite Power Plant (500 MW)  Akrimota Lignite Power Plant (250 MW)  Mundra TPP (660 MW)  Sabarmati TPS (400 MW)
  8. 8. General Layout-Power Plant
  9. 9. Syllabus topics:  Boilers  Steam Nozzles  Steam Turbines  Condensers and Cooling towers  Gas turbine  General details of thermal power station
