Co-Combustion Characteristics of Oil Shale Semi-Coke and Corn Stalk

Abstract:

The combustion experiments of oil shale semi-coke and corn stalk mixtures were conducted using thermogravimetric analyzer. The results show that the advance ignition and burnout can be achieved when semi-coke is mixed with corn stalk. The influence of different blend ratios has been studied, and the combustion characteristics were obtained. Comprehensive combustion characteristics get improved with the increase of corn stalk proportion in the mixture. The interaction of mixture in the combustion process occurs mainly in 400-600oC. It can be explained that the combustion of fixed carbon in corn stalk is delayed. What is more, TG curves were simulated by Johnson-Mehl-Avrami equation. The result shows the feasibility of using Weibull distribution to simulate the TG curves of co-combustion.
