The thermal characteristics and kinetic behavior of various solid wastes, including refuse‐derived fuel (RDF) and municipal solid waste (MSW), were investigated as a potential renewable energy source, in comparison with low‐rank coal. The experimental data were obtained in nonisothermal conditions through TGA analysis at specific heating rates. In addition to thermal characteristics of solid fuels, four isoconversional (model‐free) kinetic methods: a: Kissinger‐Akahira‐Sunose (KAS), b: Flynn‐Wall‐Ozawa (FWO), c: Friedman, and d: Vyazovkin were applied to calculate activation energies. In case of solid wastes, it is possible to say that the trend of activation energies of all isoconversional methods remains almost same in the selected region of conversion (0.1‐0.6 and 0.7‐0.9). Whereas in case of coal, Friedman model exhibits lower and inconsistent values of activation energy than others selected isoconversional methods. The experimental and modeling results revealed that that solid wastes (RDF and MSW) can be promising alternative energy sources to encounter energy crisis and uncontrolled waste disposal issues.

城市固体废物，垃圾衍生燃料和煤炭的等温非等温动力学分析

与低等级煤相比，包括垃圾衍生燃料（RDF）和城市固体废物（MSW）在内的各种固体废物的热特性和动力学行为均被研究为潜在的可再生能源。通过在特定加热速率下进行TGA分析，在非等温条件下获得了实验数据。除了固体燃料的热特性外，还采用了四种等转化（无模型）动力学方法：a：基辛格·赤平·Sunose（KAS），b：Flynn-Wall-Ozawa（FWO），c：Friedman和d：Vyazovkin用于计算活化能。对于固体废物，可以说所有同转化方法的活化能趋势在选定的转化区域（0.1-0.6和0.7-0.9）几乎保持不变。如果是煤炭，弗里德曼模型显示出比其他选择的等转化方法更低和不一致的活化能值。实验和建模结果表明，固体废物（RDF和MSW）可以成为有前途的替代能源，以应对能源危机和不受控制的废物处置问题。
