Abstract
TG-DTG thermal analysis technology was applied to study the combustion characteristic of wheat straw and wheat straw briquette at different heating rate(10,20 and 30 ℃/min).Their Combustion characteristics were investigated,such as ignition temperature,burnout temperature,combustion parameters and combustion kinetics.The results showed that ignition temperature of wheat straw and wheat straw briquette were 250-260 ℃ and increased with the increase of heating rate.Combustion parameters of biomass are higher than coal.It indicated that the combustion performance of biomass was better than coal.From the kinetic analysis,combustion reaction of wheat straw and wheat straw briquette follows the basic equation of combustion kinetics and belong to first order reaction.
