Corrosion Resistance Plate Type Air Preheater for Fired Heaters in Oil Refinery

Wintech air preheater Advantage:
 

1. Modular structure for robust performance
2. patented bulge plate design,for high heat transfer efficiency
3. Rigid heavy-duty frame assembly for long service life
4. Custom-design and experiened technology to prevent corrosion

Project:  Air preheater  low temperature section glass tube  bundle

High efficiency indicators:

1. The plate wall thickness is 0.8-2mm, and the tube's is generally 2-3mm; 
2. Under the same heat transfer conditions, K value is 1.5-2 times of the tube bundle type;
3. Under the same conditions, the pressure drop is 20% - 50% of the tube bundle type;
4. In the same 1m² space, the tube bundle can be arranged with a heat exchange area of about 20 m², while the plate heat exchanger can be arranged with a general area of 40-80 m²;
