    Product Description
     
    Air pre-heater is a kind of equipment used to improve the heat exchange performance and reduce energy consumption of the boiler, which means that the flue gas in the tail flue of the boiler will preheat the air before entering the boiler to a certain temperature through the internal radiator. Air preheater is generally divided into three types: plate type, rotary type and tube type. Taking the rotary type as an example, the working principle of air preheater is introduced. A large number of unburned combustibles will deposit on the heat transfer elements, which may cause the air preheater to ignite. The causes of ignition and the countermeasures are described in detail. The shutdown analysis and air leakage control are also introduced in detail.

     

    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.
