Product Description

Descriptions

 

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.
