Combustion test of multi-mass blending ratio of corn straw and coal gangue by using thermogravimetric analyzer with different heating rates and different oxygen concentrations. Comprehensive consideration of the synergy between factors and factors, combustion performance analysis of ignition performance, flammability, volatiles precipitation performance and comprehensive combustion performance. The results show that the optimum combination of ignition and combustibility in order of priority is: oxygen concentration 30%, mass blending ratio of corn straw and coal gangue 2:3, heating rate v =10 K/min. The optimum combination of flammability and elease of the volatile matter in order of priority is: oxygen concentration 30%, mass mixing ratio of corn straw and coal gangue 4:1, heating rate v =20 K/min. The optimum combination test of combustible combustion is: oxygen concentration 30%, heating rate v =10 K/min, mass mixing ratio of corn straw and coal gangue 2:3, and the combustible performance obtained by multi-factor orthogonal analysis has been significantly improved.
