在流化床燃烧试验台上对桦甸油页岩干馏残渣与鸡西烟煤的混烧特性进行试验研究。重点考察了质量掺混比、二次风率对床层温度与NOX等排放浓度的影响。结果表明：随着烟煤掺混比例的增大,炉膛出口温度升高,NOX生成量逐渐减少;随二次风率的增加一次风率降低,密相区与稀相区温差增大且NOX排放浓度减少,NOX排放满足国家标准。

The co-combustion characteristics of retorting residue of Huadian oil shale and bituminous coal of Jixi were conducted on a circulating fluidized bed（CFB）test bench.The major effects of mass mixing ratio,secondary air fraction were studied for the bed temperature and NOx emission concentration.The results show that the furnace outlet temperature increases and the NOx emission decreases with the increase of mixing ratio of bituminous coal.In addition,with the increasing of secondary air fraction,not only the primary air fraction decreases,the temperature difference between dense phase region and dilute phase region increases,but also the NOx emission concentration has decreased enough to meet the national standard.
