In this work, thermogravimetric analysis was used to investigate the co-combustion characteristics of wood and municipal solid waste (MSW) with Indian coal. Combustion characteristics like volatile release, ignition were studied. Wood presented an enhanced reaction rate reflecting its high volatile and low ash contents, while MSW enhanced ignition behavior of Indian coal. The results indicate that blending of both, wood and MSW improves devolatization properties of coal. Significant interaction was detected between wood and Indian coal, and reactivity of coal has improved upon blending with wood. On the other hand, MSW shows a good interaction with Indian coal leading to significant reduction in ignition temperature of coal and this effect was more pronounced with higher blending ratio of MSW. Hence MSW blending could more positively support the combustion of low quality Indian coal as compared to wood, due to its property of enhancement of ignition characteristics.
在这项工作中，采用热重分析研究了木材与城市固体废物（MSW）与印度煤的共燃烧特性。研究了挥发分释放、着火等燃烧特性。木材具有较高的挥发分和较低的灰分含量，表现出增强的反应速率，而 MSW 则增强了印度煤的着火行为。结果表明，两者（木材和 MSW）的混合改善了煤的挥发特性。在木材和印度煤之间检测到显著的相互作用，并且随着与木材混合，煤的反应性得到了提高。另一方面，MSW 与印度煤表现出良好的相互作用，导致煤的着火温度显著降低，并且随着 MSW 混合比例的增加，这种效果更加明显。因此，与木材相比，MSW 混合由于其增强点火特性的特性，更能支持低质印度煤的燃烧。
