Experimental Study About the Effect of Biomass Chemical Composition on the Combustion Characteristics of Bio-briquette

Bio-briquette combustion technology,as one of the most effective ways for biomass utilization,has attracted more and more scholar's attention in recent years due to its potential benefits for both environment and energy conservation.In this paper,the combustion characteristic of bio-briquette was analyzed on the basis of biomass chemical composition,which was analyzed by a chemical extraction process.And then the bio-briquettes with different biomass compositions were burned in a thermal analytical balance furnace.The experimental results show that increasing the quantity of biomass will improve the combustion performance of bio-briquettes,where the main factor is the cellulose composition in biomass.If considering such three aspects as the ignition temperature,the biggest release rate of volatile matter and the burn-up temperature,to evaluate the combustion characteristics,it was found that the more cellulose contains,the better the combustion performance of bio-briquette is.Finally,the concept of combustion characteristics evaluating factor for biomass briquette was introduced to quantitatively evaluate the combustion performance of biomass briquette.
