Horizontal And Vertical Type Steel Air Preheater For Boiler And Power Plant

General Introduction

Boiler air preheater is to improve performance of heating change for boilers, and reduce heat consumption. Air preheaters work to transfer the heat carried by exhaust gas from boiler tail flue to the air before entering the boiler through the cooling ribs, and heat the air to a certain temperature.

Usually it is used for coal-fired boilers in power station. They can be divided into tube-box type and rotary air preheaters.Rotary type can be divided into wind hood rotary type and heating surface rotary type. Generally boilers in power staion apply heating surface rotary air preheaters. There are two warehouses, three warehouses and four warehouses types in boilers application. Four warehouses type are commonly used for CFB boilers.

Working principles

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.
