Heat Exchangers - Air-Preheaters & Hoppers
Air Preheaters extract the waste heat from the flue gases that exit from the boilers and preheat the air before using it for combustion in the operational cycle.
The temperature of the fuel is increased from its normal temperature to conduct the combustion. Air preheaters provide hot air that helps in increasing combustion efficiency and overall boiler efficiency.
Advantages of Air Preheater
- It increases the thermal efficiency of the boiler
- Improves the combustion
- Reduce the loss of excess fuel and gas temperature
- Enhance the heat transfer
- Suitable for every type of fuels and boilers
