Ceramic Enamel Black/Blue coated Air Preheater Pipe
(1) material composition:
Seamless steel pipe, welded steel pipe.
High density corrosion resistant enamel coated
(2) performance characteristics:
Strong corrosion resistance,
not easy to accumulate ash
replace the ordinary steel pipe with enamel excellent heat transfer effect, change the layout of heat exchange parts, solve the problems of corrosion resistance, abrasion resistance, severe ash blocking, resulting in air leakage, heat dissipation and heat exchange, as well as high frequency stop the furnace maintenance, realizing the dual goal of environmental protection and energy saving. Service life greatly increased to achieve economic benefits. if there is accumulated ash, it can be washed directly with hot water at the pressure of 0.5Mpa or above without stopping the furnace, which greatly reduces the maintenance cost. In order to ensure the integrity of the enamel surface of the enamel tube, the sealing method of the enamel tube and the tube plate adopts flexible sealing. This sealing method not only effectively protects the enamel components of the tube and the tube plate from being destroyed in the sealed type, but also facilitates the construction and maintenance. The outer enamel tube preheater is arranged horizontally, that is, the enamel tube is arranged horizontally, and the temperature of the preheater tube wall is 10℃-30℃ higher than that of the preheater tube wall. That is to save heat and reduce the smoke corrosion at low temperature.
