An air preheater is a device designed to recover waste heat from exhaust gas to preheat the air for next process, usually as combustion air to burn in furnace.
Welded plate type air preheater takes welded plate bundle as heat transfer element. Each two plates are welded together along the seams by automatic laser welding machine to form a plate pair. Each plate pair are then welded onto the four columns to form a plate bundle, which is the core heat transfer body of the full set of the equipment.
The wide space channel is particularly suitable for tough flue gas containing solid and viscous particles.
Plate material can be either carbon steel or stainless steel, but very importantly the process temperature should be above 130 ºC to avoid dew point corrosion. When temperature is lower than this, a glass tubular type will be another option to solve the problem of corrosion.
A variety of stainless steel can be selected for the plate, such as 304, 316, 316L, 2205, 254 SMO, depending on the working temperature and composition of the flue gas.
