What is the function of air preheater in boiler?
Air Preheaters in Steam Boilers | Function, Types, Advantages ...
The main function of an air preheater is to extract the excess heat
from the flue gases in the boiler. As we know, combustion requires
air, fuel, and fire to take place. Air preheaters help
significantly in feeding the hot air and increasing the combustion
efficiency for the operation in steam boilers.
Description:
Air preheater(APH)is the shell and tube type heat exchangers used for preheating the air which is fed to the boiler or furnaces/ kilns for combustion of fuels. Air preheater’s primary objective is to extract the waste heat from the flue gases leaving the boiler. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater.These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
