Waste Incineration Air Preheater is a heat exchanger through the flue gas in the flue gas at the tail of the boiler through the radiator, which strengthens the medium to a certain temperature before entering the boiler, so as to supply it to the process. There are three types of Waste Incineration air preheater, namely, plate air preheater, tubular air preheater and rotary air preheater. Each type has its own different process effect.
The Plate Type Air Preheater is an advanced high efficient & energy saving type of preheater, which has the advantages of high efficient heat transfer, low pressure drop, compact structure, corrosion resistance, long service life, low soot accumulation, easy cleaning, etc. It can avoid not only the heat transfer tube burst due to high temperature, low temperature corrosion, easy block-up and premature failure of heat pipe heat exchanger, but also big volume and short service life compared with tube heat exchanger.

Advantage
1.Efficient heat transfer performance: The plate type heat transfer component has an overall heat transfer coefficient 1-3 times higher than that of tubular heat transfer component and 30%~100% higher than that of heat tube type. In view that the temperature and size change before and after the heating process, variable flowing channel is designed to ensure optimized overall heat transfer coefficient and minimized resistance drop.
2.Low pressure drop: With same heat exchange area, the flow area of plate type is 5 times bigger than that of conventional heat tube type preheater. When the medium flows in the plate type preheater, it encounters less resistance drop thanks to the straight channel, bigger flow area and shorter distance. Variable flowing channel is designed to ensure optimized overall heat transfer coefficient and minimized resistance drop. Compared with heat pipe type preheater, the plate type reduced the resistance drop by 20%-60%, which is only 40%-60% of the tubular type.
3.Good resistance against high temperature: The heat transfer component of plate preheater is made of high heat resistant stainless steel and can operate safely at a temperature up to 450ºC.
4.High reliability: The plate preheater design prevents dew point corrosion and the construction material is highly resistant against high temperature. The flow channel design takes the coal gas characteristics into account and eliminates dead area. The gas inlet nozzle is jacked and coated and a proper flow velocity is applied to avoid abrasion to the plate sheets. All these contribute to greatly improved reliability
5.Low fouling: With special corrugated design and smooth heat transfer surface, the plate type preheater hardly has soot accumulated.
6.Compact structure: The plate preheater is of high compact ratio. For tubular type (heat pipe type), it is about 60m2/m3 while for plate preheater, it is 160m2/m3, which is around 3 times higher.
