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 collectionof 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 develop the new heat transfer parts â??â??Enamel coated seam or seamless tubes with small enamel thickness ratio of thermal conductivity and received 5 patents .
The uniform colour enameled 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 best temperature change performance enameled tubes as the heat exchange parts will be anti-abrasion and anti-corrosion, the surface is smooth
and low cost of maintenance .
