OUR STRENGTHS
The enamel tube air preheater adopts low carbon steel tube as the matrix, and the enamel is mixed with new materials of high temperature resistance, corrosion resistance and wear resistance. According to a certain scientific formula, it is evenly mixed and coated on the outer surface of the steel tube, and then sintered at high temperature to form a composite tube which is not broken, crack free, acid and alkali corrosion resistant, smoke and gas resistant, high surface smoothness, low flue qas flow resistance and not easy to block ash. Enamel tube air preheater is mainly used for all kinds of boilers with air preheater as replacement products. It is mainly composed of tube sheet, enamel steel tube, heat-resistant seal and other materials.
1. Acid and alkali corrosion resistance, smoke erosion resistance, fly ash wear resistance, long service life.
2. The surface is smooth, not easy to stick ash, ash pollution heat resistance is small, flue gas flow resistance is small.
3. The heat exchange intensity is increased, the tube wall temperature is improved the total heat exchange is improved, the boiler thermal efficiency is also improved, and a lot of coal resources are saved.
4. When the exhaust gas temperature of the boiler is low, the preheate will have low-temperature corrosion, which will damage the preheater tube and cause air leakage. In order to prevent low-temperature corrosion, users have to increase the exhaust gas temperature to reduce the thermal efficiency of the boiler. Because th enamel tube is resistant to low-temperature corrosion, the exhaust gas temperature of the boiler can be reduced to 140ºC.
