“…The characteristics of low calorific and limitations of the prior art combustion value fuel, which limit its large-scale use [7], but mixed combustion is an effective way to improve their combustion and combustion efficiency [8][9][10]. The mechanism of low calorific value of blended coal combustion was understood by the study of lignite coals and coal gangue mixed combustion dynamics, which can effectively guide the combustion process.…”

“…There are many methods of the combustion process. This study that researches methods in combination with coal combustion characteristics by thermal analysis techniques, can provide strongly theoretical support for stabilizing the low calorific value fuel combustion, and offer energy use and low calorific value boiler burning some guidance significance [11][12][13][14].…”

Abstract. In this paper, the co-combustion behaviour of lignite coal with coal gangue and coal are investigated by a thermogravimetric analysis (TGA) in the temperature range from ambient temperature to 1000 ℃. The thermal characteristics and kinetics of lignite coal, coal gangue and their blends are evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA). Lignite coal is blended with coal gangue in the range of 25-75 wt. % to evaluate their cocombustion behaviour. Such attempts of Combustion characteristics index under different proportions of analysis may help to identify appropriate blend proportion for a given coal gangue and to derive some specific advantages with respect to particular combustion practice.

“…Compared to coal gangue, RDF has a much lower fixed carbon content and higher volatile content, oxygen content and calorific value. The blending of RDF with high volatile and oxygen content may improve the ignition characteristic of coal gangue which is desirable for the combustion of low-rank or high-ash coal [8]. It is noteworthy that the chlorine element in RDF is 0.73 wt.%, which is significantly higher than that in coal gangue (0.01wt.%) and gives the risk of the chloride pollutants release.…”

Abstract. In this work, the combustion characteristics of coal gangue (CG), municipal refuse derived fuel (RDF) and their blends were investigated via thermogravimetric analysis. Effects of the RDF on the whole co-combustion process like the devolatilization, ignition, and burnout characteristics were analyzed. The results showed that the combustion profiles of RDF were more complex than that of coal gangue. The blending of RDF could improve the combustion characteristics of coal gangue, especially the volatile release and ignition characteristics. Further, the kinetic results showed RDF could improve the reactivity of char combustion stage of the co-fuels and the effect was more pronounced with higher RDF blending ratio. All of these results indicated the feasibility of co-combustion of RDF and coal gangue in the existing coal gangue power station.
