Recovery of industrial surplus heat technology

According to statistics, industrial energy consumption makes up 2/3 of the whole society’s energy consumption in China, nevertheless the energy efficiency is low (less than 50%). The surplus heat resources in all trades represent 17% to 67% of the entire energy consumption, and as high as about 60% of the surplus heat resources can be reused.
With advantages in technology and products, as well as a series of advanced technology and products, we can turn the surplus heat of low quality and waste heat produced in the industrial process into usable energy to other industrial productions and municipal district heating. On the one hand, this technology can reduce energy consumption. On the other hand, we can benefit both the whole economy and society. It has been widely used in many fields, such as steel, chemical engineering, building materials, electric power, petrochemical industry, nonferrous metal, textile industry and light industry.
