Professional Customized ASME Standard Boiler Air Preheater for Industry

 

What is Air Preheater?

 

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.

 

 

What are the functions of Air Preheater?

 

1.The heat air can be the fuel desiccant.
For layer-burning boilers, it is okay to use fuel whose miosture and ash content is high when preheated air is available. For power station boilers, hot air is an important desiccant for fat power system and medium to convey coal powder.
2. Improve and enhance combusion
The air through the air preheater enters the boiler inside, and speed up the fuel processes of drying, ignition and combusion, and makes sure the stable combusion inside the bouler, and improve the combusion effieciency.
3.Reduce the boiler loss, decrease the exhaust gas temperature and improve the thermal efficiency of the boiler.
Because the combusion inside is stable, and the radiation heat transferring is enhanced, it can reduce the loss caused by chemical incomplete combusion. On the other hand, the air preheater take the advantage of gas flue heat to further reduce the exhaust loss, which thus improves the thermal efficiency. According to experience, when the air tempeature inside the air preheater is increased by 1.5 degrees, the temperature of gas flue can be decreased by 1 degree. If installed, the air preheater can preheat the air by 150-160 degrees, then can reduce the temperature of gas flue by 110-120 degrees, and increase the thermal efficiency by 7-7.5% as well as save fuel by 11-12%.
4.Enforce heat tranfer
Due to the improvement and enforcement of combusion in the boiler, as well as the increase of hot wind temperature when entering the boiler, the average temperature inside is increased, too. This can enforce the radiation heat transferrring in the boiler.
 
 

What is the working principle of Air Preheater?

 

In rotary air preheater, for example shows that the principle of air preheater, the work will slow rotation, will enter the air preheater smoke lientang then expelled, and carry the heat in flue gas will be absorbed by the cooling fin in air preheater, after the air preheater, slow rotation and fin movement to the air side, to transfer heat to the air before entering the boiler.
The application of air preheater in boiler is mostly three-compartment type with fire alarm system, clearance adjustment system and frequency conversion control system.
The air preheater is easy to use, easy to operate, safe to operate, and can improve the heat exchange performance of the boiler system, so it is widely used in the flue gas boiler system.
