摘　　要：模拟烟化炉实际生产过程,采用冶金计算法研究粉煤固定碳含量对烟化炉冶炼煤耗、氧化锌烟尘质量及水淬渣质量的影响。结果表明,当粉煤固定碳含量从45%提高到55%时,烟尘中锌、锗含量从40.58%、459g/t提高到48.00%、543g/t,水淬渣锌含量由2.25%降至1.38%,吨锌粉煤单耗从4.64t降到3.80t。计算数据与生产数据对比,确定固定碳含量不低于55%为较经济的冶炼控制点。The actual production of fuming furnace was simulated.The effects of fixed carbon content of pulverized coal on coal consumption of fuming furnace,quality of zinc oxide dust and water-quenched slag were investigated by metallurgical calculation.The results from calculation show that when fixed carbon content of pulverized coal rises from 45％ to 55％,zinc and germanium contents in dust rise from 40.58％and 459 g/t to 48.00％ and 543 g/t respectively,zinc content in water-quenched slag reduces from 2.25％ to 1.38％,and pulverized coal consumption by tones of zinc metal reduces from 4.64 t to 3.80 t.Fixed carbon content of pulverized coal of no less than 55 ％ serves as a smelting control point in economical terms for fuming furnace based on comparison calculated data and production data.
