    Boiler Air Preheater In Thermal Power Plant High Pressure


    Energy saving New Industrial Boiler Tube Air Preheater with Enameled Tube


    Product Description


    Airpreheater is a general term and represents any heater designed to heat air. It may be for residential use namely for room heating, house heating, etc. by means of gas, electricity or oil etc. In the present context reference is to the airpreheaters used in steam generators (boilers) for generation of electricity in Power Generation Utilities.

    The purpose of the air preheater is to recover the heat from the flue gas(exhaust gases) from the boiler to improve boiler efficiency. Incidentally the gases are sent to the chimney or stack at lowered temperature so that the design of the ducting and the stack becomes simplified. Also it controls the temperature of gases coming out of the stack.

    Different types


    For the use in Steam Generators (boilers)in Thermal power stations of Utility power stations, there are two types of design of the Airpreheaters. One is a tubular type built into the boiler outlet Flue_gas ducting and another one is of the regenerative type known as Ljungstrom (named after the name of inventor) Regenerative Air Pre Heater(RAPH),a rotating type. This may be horizontal (now very common in power generation utilities) or vertical.
