摘要

采用流化床反应器，研究了高含水抗生素菌渣直接燃烧的NOx、SO2排放特性。结果表明，增加过量空气系数，NOx排放浓度升高，SO2排放浓度降低；升高燃烧温度，NOx及SO2排放浓度均升高；随着燃料含水率的增加，NOx及SO2排放浓度均呈现先降低后升高的趋势。空气分级燃烧能有效降低NOx排放，二次风率增加，NOx排放浓度显著降低；当二次风率为3/7时，NOx排放浓度较传统燃烧降低50%。添加CaCO3进行炉内脱硫，实验结果显示：随钙硫摩尔比（Ca/S）增加，SO2排放浓度下降，当Ca/S 3时，SO2排放浓度降低到25 mg·m-3以下，脱硫效率超过99%。

Abstract

The characteristics of NOx and SO2 emission from combustion of antibiotic mycelial residue with high water content in a fluidized bed reactor were studied. The results showed that with the increase in excess air ratio

the NOx emission concentration increased while the SO2 emission concentration decreased. Enhancing the combustion temperature led to the increases in both the NOx and SO2 emission concentrations. With increasing fuel moisture content

both the NOx and SO2 emission concentrations first decreased and then increased. The air-staging combustion enabled good control of NOx emission. The NOx emission concentration was significantly lower with increasing the secondary air ratio. At the secondary air ratio 3/7

the air-staging combustion cut the NOx emission amount off by more than 50% compared to the traditional combustion. Desulfurization by adding CaCO3 into the furnace indicated that the SO2 emission concentration decreased with increasing molar ratio of calcium to sulfur (Ca/S)

and when Ca/S 3

the SO2 emission concentration decreased to below 25 mg·m-3 and the sulfur removal efficiency surpassed 99%.
