Principle of Thermal Power Plant
Steam Turbines • Turbines perform the energy conversion in two steps: • Step 1: Thermal energy of the steam to kinetic energy of the steam • Step 2: Kinetic energy of the steam to mechanical energy of the rotor

SITE SELECTION FOR THERMAL POWER PLANT A few important factors to be considered for the selection of site for thermal plants are listed below: Ø Ø Ø Ø Ø Availability of Coal Ash Disposal Facility Space Requirements Nature of Land Availability of Water Transport Facilities Availability of a Labour Public Problems Size of the Plant
Advantages Ø Low initial cost Ø Since located near the load centre, the cost of transmission and the losses due to transmission are considerably reduced. Ø The construction and commissioning of thermal power plant takes lesser period.
Disadvantages ü Fuel is a non-renewable source of energy. ü Efficiency decreases with decreasing load. ü Cost of power generation is high. ü Smoke produced by burning the fuel causes air pollution. ü Life of thermal power plant is 25 years. The efficiency decreases to less than 10% after its life period. ü Turbines has a high running speed of 3000 to 4000 rpm.
