桉木与煤掺混燃烧实验研究
Experimental Study on Co-combustion of Eucalyptus and Coal
摘要
Abstract
Aiming at the systematic scientific problems that need to be solved in the process of coal-fired coupling biomass co-combustion,typical biomass eucalyptus was selected as raw material to co-combustion with coal.The comprehensive thermal analyzer,fixed-bed reaction system,and ash composition test techniques were employed to investigate the co-firing characteristics,pollutant emission behavior,and slagging properties during the co-combustion process of eucalyptus and coal.Experimental results illustrate that with the increase in the blending proportion of eucalyptus,ignition temperature,burnout temperature,and activation energy all reduce consistently.At the eucalyptus mass blend ratio of 10%,the overall combustion characteristic index and the comprehensive burnout characteristic index increase by 36.2%and 13.55%respectively.The reduction in the total conversion of pollutant fuel types NO and SO2 is most pronounced at eucalyptus wood mass blending ratios of 5%to 15%.When the Eucalyptus mass blending ratio reaches 30%,the melt feature temperature falls 56～100℃.In the high-temperature phase,the melted eucalyptus small particles can adhere to the coal ash and coke particles,leading to incomplete combustion and exacerbating the particle adhesion phenomenon,thus augmenting the risk of furnace slagging.Therefore,the blending ratio of eucalyptus should be maintained below 30%to manage these adverse effects.关键词
