Abstract：Abatract:Aiming at the recovery of sintering waste heat and the removal of CO from sintering flue gas,a vertical sintering waste heat recovery system with sintering flue gas as the cooling medium is designed,and enthalpy analysis and combustion calculation are carried out on this system.The results show that the thermal utilization rate and thermal efficiency of the vertical cooling kiln can both reach over 70%,that of the air preheater can reach over 90%,and that of the flue gas preheater can reach over 60%.The thermal conversion rate of all subsystems can reach over 95%,and the comprehensive flue gas CO concentration of the system can be reduced to 674.37 mg/m3.This system can provide a reference for the improvement of the sintering waste heat recovery process in factories.
