摘要
在试样质量以及其他的试验条件基本相同的情况下,将煤与生物质(牛粪)按一定比例混合,对其进行热值测定、燃烧速率及污染物排放特性分析。结果表明,在试验用煤中加入生物质(牛粪)其热值降低,燃烧速率在燃烧前期增大,中后期变化不大,主要污染物SO2,NOx排放浓度却均有不同程度的降低,另外对生物质能降低热值及SO2,NOx排放的原因进行了讨论。
Under the same condition of sample quality and experimental circumstance,coal and biomass briquette were mixed to co-fire by a certain percentage,then the calorific value was measured and the burning rate and pollutant emission characteristics were analyzed.The results showed that biomass briquette was added into coal which would reduce calorific value,but increase burning rate in earlier period and decrease the main emission concentration of SO2 and NOx in varying degree.In this paper,the reasons of above conclusions were discussed.
