Experimental Research On Combustion Of Biomass And Coal

Co-combustion biomass and coal is a kind of new combustion technology to reduce pollutants emission and synthetically utilize biomass and coal energy sources.The peanut shells,coal,and their mixtures at different ratios were tested by using thermogravimetric analysis in differernt heating rate(5℃/min,10℃/min,20℃/min and 40℃/min) and different ratios in this paper,the combustion parameters such as ignition temperature,peak temperature of maximum weight loss rate,burn out temperature,maximum rate of combustion,and combustibility index were also analyzed in this paper.The influences of the heating rate and the different ratios was analysised on the process of combustion. The results showed that TG temperature curve moved to the high-side with the heating rate increasing; The advance ignition and better burnout property can be achieved when coal was mixed with biomass,the utility value of biomass also can be increased.
