Steam Boiler: Air Heater of Steam Boiler

The hot air produced by air heater to enhance combustion of all fuel and is needed for drying fuel like coal in stoker steam boiler. The air heater is usually the last heat trap in the steam boiler. Air heater exit gas temperature should be higher than the corrosion limit of the AH internals and the downstream equipment.
