Types of Air-preheater and their Advantages and

Perfect and efficient combustion of fuel can be achieved in a boiler, if the atmospheric air can be preheated by the low temperature flue gas, which is otherwise going to be wasted through the chimney. Air preheater is situated at the exit end of the flue gas path, after economizer. Air preheating is helpful in following ways:-

why economizer and air pre-heaters are provided in boilers

Why Economizer and Air Pre-Heaters are Provided in Boilers

Tubular or recuperative air pre-heaters are provided in boilers of medium and small range of steam generation. This type of air pre-heater becomes very large in size if they have to be used in very high capacity boilers like 600 tons/hr of steam production and above. In these cases regenerative air pre-heaters are used.
