摘要(Abstract)：

火电行业的降碳工作直接关系到“双碳”目标的实现，而循环流化床炉具有燃料适用性广的优势，能够大比例掺烧可再生“零碳”能源-生物质燃料，大幅降低火电厂碳排放。在役循环流化床炉和燃煤条件，进行生物质混合掺烧试验，并对燃烧稳定性、污染物排放及热效率进行了综合评估。掺烧试验结果表明：生产单位蒸汽煤耗量随掺烧比增大显著降低，燃烧工况稳定；掺烧条件下单位石灰石耗量降至4.5 kg/t蒸汽左右，SO_2排放量达标；掺烧后炉内温度升高，排烟温度升高，而飞灰量增大，使热损失有所增大；通过调控风量配比、料层差压及过量空气系数，总体热效率接近设计值；长期运行条件下，生物质掺烧比达到约30%,SO_2和NO_x排放量合格，尾部受热面未受明显腐蚀，1 t蒸汽减排CO_2量约480 kg。
