Experimental Study on Oxygen-enriched Combustion Characteristics of Pure Cotton

This paper describes the oxygen-enriched combustion characteristics of pure cotton from municipal solid waste applying the non-isothermal thermogravimetric analysis, the apparent activation energy and the pre-exponential factor of oxygen-enriched combustion were obtained by kinetic analysis. Experimental results show that the pure cotton combustion process consists of two phases, which are volatile release and combustion phase and fixed carbon combustion phase. It has been found that combustion performance of pure cotton improves when oxygen concentration increases to certain value and compensation effect exists in pure cotton combustion with the variation of oxygen concentration. The experimental results can provide direction for disposal of pure cotton as an energy resource.
