摘要

利用自建的SO2测量系统

对富氧气氛下生物质/煤恒温混燃过程进行了SO2测量实验

深入研究了气氛、掺混比、温度、煤种及生物质种类等因素对SO2释放的影响规律。结果表明:生物质/煤混合样品在富氧气氛和空气气氛下的SO2瞬时生成曲线形成1个剧烈释放峰和1个平缓的释放峰；在21%氧体积分数下

富氧气氛下的SO2双峰和总释放量均小于空气气氛

随着氧体积分数的升高

SO2总释放量增大；随着玉米芯掺混比的增加

SO2总释放量均呈下降趋势；随着温度升高

SO2总释放量增大

温度从900 ℃增加到1 000 ℃时

SO2总释放量的增加幅度大于从800 ℃增加到900 ℃下的情况；阳泉无烟煤、塔山烟煤、印尼褐煤3种煤在掺混玉米芯后

SO2总释放量均有不同程度的降低；阳泉无烟煤掺混3种生物质后的SO2瞬时生成曲线2个释放峰值均有所降低

SO2总释放量均明显降低

但降低程度有所不同。
