Combustion of rice straw under different oxygen concentrations was studied by using TG analysis in this
paper. Effects of oxygen concentration and various heating rates on TGA of rice straw were thoroughly
analyzed. Mass loss rates of straw combustion under different oxygen concentrations were similar when
temperature was below 230°C. The volatile release end temperature decreased with the oxygen
concentration increasing, the temperature, associated to maximum weight loss rate, is lower under higher
oxygen concentration except O2:N2=60:40. The weight loss rate of combustion shifted to a higher
temperature with heating rates increasing.
