Abstract
The effect of waste plastics addition on combustion characteristics of Chuanmei coal and Wuben coal was studied comparatively by thermogravimetry. The results show that adding waste plastics can increase the maximum weight loss rate, reduce the ignition temperature, decrease the burnout temperature and the temperature of the maximum weight loss speed of the pulverized coal, which effectively improves the combustion rate of pulverized coal; At the same waste plastics addition ratio, the combustion effect of low volatile pulverized coal is superior to that of high one, and the most obvious effect of combustion occurs in a relatively low temperature region (500°C); At different waste plastics ratios, when the addition is higher at about 20%, the combustion effect is most obvious; when the addition is lower at 0.5%, the combustion of pulverized coal is significantly improved.
