Thermal Power Plant (ST): Steam is an important medium of producing mechanical energy. Steam has the advantages that it can be raised from water which is available in abundance it does not react much with the materials of the equipment of the power plant and is suitable at the temperature required in the plant. Steam is used to drive steam engines, steam turbine etc. Thermal electrical power generation is one of the major methods. For a thermal power plant the range of pressure may vary from 10 kg/cm 2 critical pressure and the range of temperature may be from 250 0 C to650 0 C.                              Figure: Steam Power Plant Main parts of a steam power plant:             1.       Boiler (Babcock and Wilcox) 2.       Steam turbines (LPT, IPT and HPT) 3.       Super heater 4.       Heaters (LPH and HPH) 5.       Condenser 6.       Air Compressor 7.       Pumps 8.       Economizer 9.       Generator                        Figur
