摘要: 烧结生产过程产生了包含颗粒物、二氧化硫、氮氧化物和二口恶英的高温烧结废气.为减少烧结污染物排放,制备新型生物质燃料取代烧结矿石燃料,通过生物质炭化、生物质成型等对比实验确定优化生物质燃料最优实验条件.实验结果表明:锯末炭化分为两个阶段,在室温(25℃)~400℃适宜炭化升温速率为5℃/min,在400~600℃适宜炭化升温速率为20℃/min,锯末燃料适宜成型压力为50MPa.通过对适宜条件下制备的生物质烧结燃料与烟煤和焦炭进行对比实验,其比表面积、孔容孔径和燃料燃烧性能大幅改善,接近矿石燃料.

Abstract: Sintering is an important process during producing iron and steel in industry, however, it produces a large amount of high-temperature sintering flue gas which contains particulate matter, sulfur dioxide, nitrogen oxides, dioxins, etc. In order to reduce sintering pollutant, a new type of biomass fuel to replace the traditional coke fuel was prepared and the optimized preparation condition of the biomass fuel was studied by comparing the results from the experiments of biomass carbonization and biomass forming. The results show that the sawdust carbonization is divided into two stages: the suitable carbonization heating rate is 5℃/min at the stage of room temperature (25℃) to 400℃ and 20℃/min at the stage of 400℃ to 600℃. The sawdust optimal forming pressure is about 50MPa. By the comparison of the performance of optimized biomass fuel and traditional ore fuel, it is indicated that the effectiveness of biomass fuel can be close to that of ore fuel after improving the specific surface area, pore volume and fuel combustion performance.

Key words: sintering flue gas, biomass forming, biomass carbonization, biomass fuel
