Özet
The urgent need to reduce greenhouse gas emissions entails a cleaner waste treatment technology. The oxy-fuel co-combustion can recover energy and reduce the waste stream. This study aims to fill the knowledge gaps about the impacts of atmosphere type, blend ratio, oxygen concentration, and their interactions on the co-combustion behaviors and products of durian shell (DS) and textile dyeing sludge (TDS). The higher oxygen concentration reduced the reaction temperature, advanced the inhibition temperature, and promoted the decomposition rate with no significant effect on the residual mass. The N2 atmosphere resulted in a better co-combustion performance than did the CO2 one. The increased addition of DS improved the co-combustion performance. At the same oxygen concentration, the maximum absorption intensity of CO was higher in the N2/O2 than CO2/O2 atmosphere. Similarly, the maximum absorption intensities of C-O(H) and C=O were higher in the CO2/O2 than N2/O2 atmosphere. The co-combustion did not increase the issues of slagging and scaling. The main components of DS, TDS, and their blend ash with 50% DS and 50% TDS included MgO, Fe2O3, and Fe2O3, respectively.
