A method for reducing slagging on heat transfer surface of the system

The present invention relates to reduce slagging on heat transfer surface technology, in particular, a method of reducing slagging on heat transfer surface, comprising a boiler provided in the flue Slag, said Slag convection superheater located at the top of the flue upwind side of the front end, the slag trap comprising a straight tube condenser disposed between the fixed disc and the two discs are arranged symmetrically, slag may roll along the axial direction of the flue; slag present invention is applicable to any high alkali content of coal boiler slag in advance, to protect the safe operation of the convection heating surface, increasing the boiler operating time; slag is arranged a straight tube furnace exit gas temperature decreases due tANGENTIAL FIRING due to combustion deviation and uneven flow field, avoiding frequent convective superheater and reheater tube; slag, slag cleaning process does not affect the normal operation of the boiler, the boiler extended operating time, improving the economy of the plant.
