Thermogravimetric-Fourier Transform Infrared Spectroscopy was conducted to evaluate the combustion characteristics of refuse derived fuel (RDF) adding of microwave chlorine depleted pyrolyzate in the mass proportion of 5-15%. It studied the catalyze effect of chlorine depleted pyrolyzate on RDF combustion performance. The combustion process of RDF could be divided into four stages. The temperature range of the most significant combustion stage of 10-RDF was much more extensive than another three ones. According to the FTIR analysis, the addition of chlorine depleted pyrolyzate might promote the combustion of CH4 and carbonyls to CO2 and H2O earlier. Based on the distributed activation energy model (DAEM), the E value of RDF with chlorine depleted pyrolyzate added was much lower than that with no chlorine depleted pyrolyzate added. The chlorine depleted pyrolyzate enhanced the combustion performance of RDF with the lower ignition, lower burnout temperature, better combustion ability, better flammability and more outstanding combustion performance. The best combustion characteristic was obtained when the dosage of chlorine depleted pyrolyzate was 10%.
