Biomass is mainly composed of cellulose, hemicellulose and lignin. The content of each component has a great influence on the combustion of biomass. The combustion of biomass starts from its thermal decomposition. The main products of cellulose and hemicellulose are volatile components, while the main products of lignin are coke, and cellulose and hemicellulose are easier to decompose than lignin. Therefore, biomass combustion is a very complex process. In order to improve the quality of straw biomass fuels and pyrolysis with high efficiency, thermogravimetric-differential thermogravimetric (TG-DTG) technology was used to conduct thermogravimetric tests on agricultural straw fuels. The combustion characteristics, ignition characteristics, burnout characteristics and comprehensive combustion characteristics were investigated, and the combustion kinetics parameters were calculated.
