Description
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
Water Pre Heaters consist of tubes for feedwater to pass through. The tubes in the water preheater receive latent heat for feedwater from the condensed high-temperature steam.
Water Preheaters pre-heat the water used for the operation in steam boilers. It increases the feedwater quality, thereby improving the boiler efficiency and reducing operating costs and chances of thermal shock in the boilers.
Advantages of Water Pre-Heater:
- Easy to Operate and Maintain
- Easy to Install
- Avoids Corrosion and Scaling
- Cost-Effective
- Higher Efficiency and Longer Life Cycle
