As the technology in the filed utilizing sintering waste heat, CIE has up to international advanced level to maximize its energy-saving effect. The waste heat of ring cooling machine independently developed by CIE has reduced its energy consumption greatly based on cascade air supply technology, directly connected furnace hood type waste heat boiler generation technology, efficient comprehensive utilization waste heat in sintering process, heat removal from big flue, and other technologies, which have been used many engineering projects at home and abroad. We have seen its good economic and social benefits based on the following data - average annual tons of mineral power generation of over 20 degrees, self-use electricity rate less than 20%, annual standard coal saved over 500,000 ton, and carbon dioxide emissions reduced to one million tons.
