General Introduction: Air Preheater
Air preheater, or boiler preheater, is an important boiler part. It can be divided into two kinds, Tubular type air preheater and Vertical type air preheater.
Air preheater pipe type, mainly using industrial furnaces or smoke waste heat boiler combustion air preheating furnace enter, such not only improves the thermal efficiency of the stove and reduce the environment pollution.
Take the rotary type as a example to illustrate the working principles of air preheaters, when under operation, it would be slowly rotating, and exhaust gas will enter the gas flue side of air preheater, and then be dicharged. The heat carried by the gas flue will be absorbed by the cooling ribs of the air preheater, then the air preheater will be rotating slowly, the cooling ribs work to the side of the air, delivering the heat to the air before the air enters the boiler.
The air preheaters applied in boilers are mostly three warehouses type with fire alarm system, internal adjustment system and frequency conversion control system. It is convenient to use air preheaters with easy operation and safe running, meanwhile it can improve the performance of heat transferring of the bouler system, thus it is very common to apply air preheaters in the system of boiler gas flue.
The main heat transfer component of tubular air preheater is thin-walled steel tube. The tubular air preheaters are mostly cubic. The steel tubes are arranged vertically and staggered with each other. Both ends are welded on the upper and lower tube sheets.The tubular air preheater is equipped with an intermediate tube sheet in the tube box. The flue gas passes through the preheater up and down the pipe, while the air passes through the preheater horizontally to complete heat transfer.
Tubular air preheater is widely used in power station boilers and industrial boilers because of its advantages of good sealing, high heat transfer efficiency, easy manufacturing and processing. The shortcomings of tubular air preheater are large volume, easy ash plugging of steel tube content, difficult cleaning and easy wear and tear at flue gas inlet.
