What is an air preheater?
Air preheater, also known as air preheater, is a preheating equipment to improve boiler heat exchange performance and reduce heat loss. The function of air preheater is to transfer the heat carried in the flue gas discharged from the flue at the tail of the boiler to the air before entering the boiler through the heat sink and preheat the air to a certain temperature.
