Recently, I believe that the company announced that it has obtained a practical new patent called "a kind of cement kiln furnace tail heat boiler with heterotical spiral fin tube and tube ". The patented technology will bring a major breakthrough to the use of the waste heat of the cement kiln kiln. It is understood that the heterogeneous spiral wing tube and tube tube have extremely high thermal exchange efficiency. Under smaller steel consumption, it can effectively convert the remaining heat of the cement kiln kiln into useful thermal energy. This can increase the utilization rate of residual heat, increase power generation load, and increase corporate efficiency. In particular, the existing traditional kiln tail waste heat boiler is upgraded and transformed, reducing the temperature of the boiler export smoke temperature, increasing the utilization rate of residual heat, and has the advantages of small investment. I am convinced that the company has been committed to the research and development and promotion of energy conservation and environmental protection technology. Obtaining a practical new patent this time is another important achievement of the company's technological innovation. The company will continue to increase investment in R & D and provide customers with more efficient and environmental protection solutions.
