Air pre-heater is a heat transfer surface in which air temperature is raised by transferring heat from other media such as flue gas. Hot air is necessary for rapid combustion in the furnace and also for drying coal in milling plants. So an essential boiler accessory which serves this purpose is air pre-heater. The air pre-heater are not essential for operation of steam generator, but they are used where a study of cost indicates that money can be saved or efficient combustion can be obtained by their use. The decision for its adoption can be made when the financial advantages is weighed against the capital cost of heater in the present paper we have taken up the operation and performance analysis of LJUNGSTROM AIRPREHEATER27VITM 1900 of 2x210 MW capacity Rayalaseema Thermal Power Plant, Kalamala and compare with Rothemuhle air pre-heater. In analysis of performance preventive measures for corrosion of heating elements has been studied, and also air heater leakage, corrected gas outlet temperature and finally gas efficiency has been calculated.
