Product Description

Air preheater

Brief Introduction
Air preheater is the equipment that uses the boiler tail flue smoke to heat the entering air with its inside tubes .It is used to improve the heat exchange performance of the boiler, and reduce energy consumption.

Advantages

1.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.
2.Strengthen heat transfer due to improved and intensified combustion furnace, 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.

3.It reduces the loss of the furnace, reduces flue smoke temperature, improves the thermal efficiency of boiler.The flue smoke waste heat is used by the air preheater, further reducing the exhaust smoke loss. According to experience, when the temperature is raised 1.5ºC  in the preheater , exhaust temperature can be reduced to 1 ºC. After Installing air preheater in boiler flue, if the air can be preheated to 150~160 ºC. It can reduce the flue gas temperature of 110~120 ºC, the boiler can be improved thermal efficiency of 7%~7.5%, can save fuel 11%~12%.
