An air preheater (APH) is a general term used to describe any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.

Normal air preheater exist the problem of collection of ash,worn down,low temperature corrosion to effect the safe and economical operation for the boiler unit. So HTEG established the exclusive enamel research and development center to supply the complete solution and organize the scientific reserach personnel to tacle key problems and develop the new heat transfer parts-enameld tubes air preheater

Function of surface smooth&effiency saving boiler heat exchanger parts air preheater for steam boiler

The purpose of the boiler heat exchanger parts air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas. As a consequence, the flue gas are also conveyed to the flue gas stack (or chimney) at a lower temperature, allowing simplified design of the conveyance system and the flue gas stack. It also allows control over the temperature of gas leaving the stack (to meet emissions regulations, for example).

Advantages of our product GB3274 enameled tube air preheater

a).Improve and strengthen the combustion when crosses air preheater then enters the furnace, accelerates the fuel drying,the ignition and combustion process, ensures stable combustion in the furnace, and it is good for improving, strengthening the combustion effect.
b). strengthen heat transfer due to improved and intensified combustion furnance and the hot air temperature in the furnace is improved, the average temperature level in the furnace is improved, thereby strengthening the furnace radiation heat transfer.
