What is an Air Preheater (APH)
An Air Preheater (APH) is a heat exchange device used to heat the air before it enters the furnace or combustion chamber of a boiler. The main purpose is to improve thermal efficiency by recovering heat from flue gases that would otherwise be wasted.
Where is it Used?
- Industrial boilers
- Power plants
- Furnaces
- Steam generation systems
Common industries:
Cement, Sugar, Paper, Textile, Food Processing, Chemical, and Steel Plants.
Working Principle
- Flue gas exits the boiler after combustion and passes through the APH.
- Cold air (combustion air) is drawn from the atmosphere.
- The APH transfers heat from the hot flue gas to the cold incoming air.
- As a result, air entering the furnace is preheated, reducing the fuel required for combustion.
This process leads to:
- Better fuel combustion
- Reduced fuel consumption
- Lower emissions
- Improved overall boiler efficiency
Types of Air Preheaters Tubular Type:
- Has steel tubes where flue gas and air pass.
- Simple design, often used in medium-capacity boilers.
Plate Type:
- Thin metal plates stacked in a chamber.
- Compact design, good for small spaces.
Rotary Type:
- Cylindrical rotating matrix that transfers heat from flue gas to air.
- Common in large-capacity boilers.
- Very efficient, but more complex.
The Benefits of Our Air Preheater Systems:
- Increased Efficiency: Our APH systems enhance boiler performance by utilizing residual heat, resulting in lower energy costs.
- Construction: Our heavy-duty designs utilize in order to withstand the rigors of the industrial environment.
- Customization: There are very few applications in which we cannot provide a custom designed systems to your application requirements.
