Enameled tube air preheater

The air preheater exists the problem of collection of ash, worn down, low temperature corrosion to effect the safe and economical operation for the boiler unit. At the moment, the investment of air preheater is 6%-8% of the whole boiler investment in the industrial boiler and power station boil, due to the problem of collection of ash, worn down, low temperature corrosion to incur the direct loss of replacing equipment and shuting down is 4%-5% of the operation cost and the loss will be more large when the boiler is shut down incurred by this problem.

Aim at the above questions, we established the established the exclusive enamel research and development center to supply the complete  solution and organize the scientific research personnel to tackle key problems and proceeds the large quantities of stimulated test and operation test to develop the new heat transfer parts--enamel tubes and receive 5 patents. The enamel steel tube is manufactured with the enamel which is our own developed with the scientific formula and is evenly coated on the surface of the steel tube by the auto enamel tube production line. To use enamel tubes as the heat exchange parts will be anti-abrasion and anti-corrosion, the surface is smooth and low cost of maintenance.

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.
