Sintering process consumes much energy and produces large amount of flue gas and circular cooler waste gas containing huge heat, most of which are not recovered. In view of the instable characteristics of sintering production, the feasibility of complete recovery and utilization of flue gas waste heat of sintering ring cooler and the best combustion of BFG volume in combination with the sintering waste heat power generation technology was dis-cussed. It was finally determined that the sintering waste heat power generation system with the parameters of afterburning to medium temperature and medium pressure is economically optimal.
