Study on combustion atmosphere and reaction kinetics in biomass mixed coal
This paper systematically studies the combustion atmosphere and reaction dynamics in the process of biomass blending coal.The ignition temperature of the straw/white sand coal sample with 2:8 mixing ratio decreased from 549℃of pure coal to 507℃,and the comprehensive combustion characteristic index(SN)value increased to 8.88833×10-9.Kinetic analysis showed that mixing reduced the activation energy and prefinger factor of the combustion reaction.The activation energy of Baisha coal was 138.45kJ/mol,while the mixing ratio of 1∶9 and 2∶8 decreased to 71.55kJ/mol and 61.84kJ/mol,respectively.
