Combustion character and kinetic analysis of biomass straw

Two samples of biomass,which are wheat straw and corn straw,were analyzed on their combustion properties through the TG-DTG technology.The ignition,burn-out characters and the integrated combustion properties of each sample were studied.Based on simultaneous thermal analysis,the combustion process of biomass can be broadly separated into three stages:evaporation of water,release and combustion of volatile,combustion of fixed carbon and burning out.The experiment results indicate that biomass has some better combustion characteristics.They are revealed that biomass has a low ignition point,low burn-out temperature and high burn of rate.Kinetics parameters of activation energy E and frequency factor A were deduced by appropriate reaction kinetics equations.It indicated that biomass has lower E value.So it's easy to be ignited.
