Spiral fluted tube features:
flue gas flowing within the spiral groove tube strong turbulence disturbance occurs, enhanced heat transfer, heat transfer coefficient than the doubling of the light pipe. Therefore, the overall heat transfer coefficient of the air preheater increased by 50% compared with fluorescent tubes, the wall can be increased by 20 degrees over about efficiency and reduce the low temperature corrosion plugging ash, reduce exhaust gas temperature increases air temperature increase boiler efficiency.
I am using patented technology, spiral fluted tube inlet and outlet in a highly wear resistant coated enamel, can solve the problem of wear and low temperature corrosion preheater, preheating is life expectancy. (This enamel coating has a coefficient of expansion slots and the same tube, ensure the chill below 500 ºC not chipping, chipping temperature soldering completely.)
The company's products in the preheater installed at the upper 300mm separator between the upper plate and the installation of steel tube filled with high temperature packing wear. Make sure never wear preheater inlet air leakage.
The company selected the most advanced patented machinery and equipment, production efficiency and product quality have good assurance, all products come with quality assurance and material list.
