摘要：Starting from the perspective of source reduction, the emission characteristics of particulate matters in sintering flue gas and sinter quality were studied by a sintering cup based on the fixed carbon 3.6% conditions in sintering raw materials. The particles were sampled by an Andersen 8-stage impactor at the coke powder ratios at 100%, 75%, 50% and 0%. The results showed that the particles in the sintering flue gas were mainly fine particles below 2.63 μm. When the coke powder ratio was 100%, the removal efficiency reached the maximum value of 34.37%. The effects of coke powder ratio on the sinter index were reflected in: when the coke powder ratio reduces, (1) the sintering speed decreases; (2) the solid fuel consumption increases; (3) the drum index improves. Compared with comprehensive indicators, the 100% coke powder was the most conducive condition to the production of enterprise sintering process.
