  • Air preheater

    Air preheater. The air preheater uses the hot feed water to preheat the combustion air and obtain a cool water flow in the return. This cold flow can now be used in an additional economiser bundle to further reduce the flue gas temperature. This increases efficiency by 2% points, or flue gas temperatures that are roughly 40K lower.

  • IMPROVING BOILER EFFICIENCY BY USING AIR PREHEATER

    2020-2-21 · Abstract: 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.
