摘    要:通过在一小型流化床中进行高水分煤的燃烧与排放的试验研究,表明水分含量和空气-燃料比对于高水分煤的燃烧与排放有较大影响。随着水分增加,流化床床温下降,NOx、SOx排放量也下降。空气-燃料比存在一最佳值,这时床温最高,而偏离此值,床温下降,随着空气量的增加,NOx、SOx排放量也增加。当空气-燃料比变化时,燃烧干煤与燃烧高水分煤有着类似的试验结果。

关 键 词:水分,煤,流化床燃烧

Abstract:The combustion and emission characteristics of high moisture coal have been studied in a fluidized bed reactor. The results indicate that the moisture and the air fuel ratio have significant effect on the combustion and emission of high moisture coal. With increasing moisture, bed temperature and NO x , SO x emissions decrease. The air fuel ratio has an optimal value, at which the bed temperature is maximum. With increasing the ratio, NO x and SO x emissions increase. For the combustion of dry coal, the results with varying air fuel ratio are similar to those for the combustion of high moisture coal.
Keywords:Moisture  Coal  Fluidized bed combustion
