Abstract

Abstract

In this study, the combustion characteristics of combustible waste, pulverized coal and their mixture were analyzed by thermogravimetric analysis. The results showed that the thermogravimetric curves of combustible waste had two obvious weight loss regions in the temperature range of 220~500℃, and only one obvious weight loss region of pulverized coal in the temperature range of 300~600℃. Combustible waste had good ignition performance, and the ignition point was 220℃. The ignition point of combustible waste mixed with pulverized coal was slightly higher than that of the combustible waste, but it was also obviously lower than that of pulverized coal combustion alone. Mixed combustion basically maintained the ignition characteristics of the combustible waste, when mixed with pulverized coal. When the blending proportion of combustible waste was not more than 80%, there was an obvious synergistic promoting effect between combustible waste and pulverized coal mixed combustion. The comprehensive combustion characteristic index of combustible waste was 3.91×10^-7/(min²·K³), obviously higher than that of the pulverized coal. The addition of the combustible waste could improve the comprehensive combustion performance of the pulverized coal, and the best ratio of combustible waste to pulverized coal was 4:1. The results of combustion kinetic analysis showed that the activity of the mixed fuel was higher than that of the combustible waste at 220~330℃ combustion stage, and the activity of the mixed fuel was slightly lower than that of the combustible waste at 320~570℃ combustion stage, but much higher than that of the pulverized coal. The addition amount of the combustible waste had little influence on activity of the mixed fuel in the two combustion stages.
