摘　　要：通过烧结杯试验,研究了煤粉与生石灰预混对烧结过程烟气中SO2和NOx排放的影响,总结了SO2和NOx在烧结过程中的排放规律。在预混煤粉占煤粉总量85%,预混生石灰占生石灰总量30%的条件下,可以有效降低烧结烟气SO2和NOx的排放,而且可以获得较好的烧结指标。The effect of premixing pulverized coal and lime on SO2 and NOx emission in sintering was studied by sintering cup test, and the emission rules of SO2 and NOx were summarized.When premix-ing 85%coal and 30%lime, the SO2 and NOx emission in sintering flue gas can be reduced effectively and ideal sintering indicators were got.
