Direct High Efficiency Industrial Boiler Part Air Preheater

Enameled tube air preheater

Product advantages:

1.Anti-corrosion, wear resistance, anti-ash fouling, and long service life

2.Small covering area;

3.Pipe and tube plate in every link between separated, the heated bilges cold heat distortion is not bound to avoid stress destruction;

4.Single pipe, tube single or parts of equipment failure does not affect the heat normal operation;

Applications:

To adapt the different boiler burning type, different fuel and different fume ingredient, we developed the below enamel tube air preheaters to fit the different medium:

1. The CFB boiler and coal powder boiler used enamel steel tubes, seam or seamless steel tube with green colour.

2. The rubbish burning furnace, biomass boiler used enamel steel tubes, seam or seamless steel tube with blue colour.

3. The Chain grate and layer burning boiler used enamel steel tubes, seam or seamless steel tube with brown colour.

4. The oil burning boiler, coking boiler and gas boiler used enamel steel tubes,seam or seamless steel tube with dark green.

Features

1. The preheater tubes are not easily broken enamel surface, no crack, acid and alkali resistance, resistance to gas erosion, smooth and high, gas flow resistance, easy Fouling;

2. As the flue gas across tube, the flue gas side of the heat capacity of exile to strengthen, under the same heat transfer coefficient (enamel thickness ratio of thermal conductivity with very small, about 0.0002, the calculation is negligible), wall temperature vertical preheater than ordinary steel increased 10-30 Degree Celsius, the overall heat transfer coefficient of about 20.3-24.2W;

3. Two horizontal enamel sealing tube box, the sealed tube box structure welded high strength, pipe damaged or the overall change can only block, and heat-packing seal, can only replace the damaged pipe tube, easy maintenance;

4. The preheater is mainly used for boiler preheater, the low temperature.
