Enameled air preheater

Product Details

Enamel air preheater products are usded as per below conditions:
1.Enamel heat exchanger designed for denitration renovation projects
2.Enamel heat exchanger for circulating fluidized bed boiler and pulverized coal boilers Heat
exchanger parts for garbage incinerators and biomass boilers
3.Heat exchanger parts for grate furnaces, like chain grate furnaces4.Heat exchanger parts for gas-fueled boilers, such as kerosene boilers, coke ovens, etc.

Features of enamel tube air preheater

1. Boiler heat transfer parts enamel tube air preheaters 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. Boiler heat transfer parts enamel tube air preheater is mainly used for boiler preheater, the low temperature.

Specifications of enamel tube air preheater

1.High corrossion resistance proerty;
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
