Product Description

Air preheater is a heat exchange equipment which uses waste heat of flue gas to heat the air needed by boiler combustion.

High temperature section full welding plate type characteristic:

Can achieve the flue gas inlet, air outlet<10ºC difference, the best utilization of waste heat;

The surface of plate is smooth and not easy to accumlate dust, so as to avoid the increase of fouling heat resistance and the decrease of efficiency;

Low temperature section characteristic

The surface is smooth, not easy to accumulate ash, completely solve the problem of low temperature dew point corrosion.

 

Product characteristics:

 

1. The heat transfer element is stainless steel plate, and the turbulent flow can be formed under very low Reynolds number by the plate-to-plate internal self-disturbance structure, thus improving the heat transfer coefficient. The efficiency of heat exchanger is 2-3 times of that of ordinary finned tube air-cooling.

 

2. The compactness of fully welded plate wet air cooling is about 220 m2/m3, which is much larger than that of tubular air cooling at 78 m2/m3.

 

3. Under the same heat transfer area, the fully welded plate air cooler is small in size and light in weight, which can greatly save the installation space and cost of users'equipment.

 

4. The unique spray evaporation structure makes use of the phase change heat of the fluid and greatly improves the heat transfer capacity.

 

5. Induced air design, more uniform air flow, better heat transfer effect.
