摘要

采用热重分析与傅里叶变换红外光谱相结合的方法，研究了玉米秸秆、聚乙烯和无烟煤三组分燃烧过程中的协同效应。热动力学分析表明，玉米秸秆是反应最活跃的原料，有两个反应阶段（38.03 kJ·mol−1,54.63 kJ·mol−1），其次是聚乙烯（134.60 kJ·mol−1）和无烟煤（118.64 kJ·mol−1）的单反应阶段。与基础组分、聚乙烯和无烟煤相比，三燃料混合物在每个燃烧阶段的活化能都较低。混合燃料燃烧表现出协同反应机制。玉米秸秆、聚乙烯、无烟煤等原料的合理配合能显著改善燃烧特性。

Synergism study on tri-combustion of cornstalk, polyethylene and anthracite coal

The synergistic effects during the tri-combustion of cornstalk, polyethylene, and anthracite coal were investigated using thermogravimetric analysis coupled with Fourier transform infrared spectroscopy. The thermokinetic analysis identifies cornstalk as the most reactive feed material with two reaction stages (38.03 kJ·mol⁻¹, 54.63 kJ·mol⁻¹) followed by a single reaction stage for both polyethylene (134.60 kJ·mol⁻¹) and anthracite coal (118.64 kJ·mol⁻¹). Tri-fuel blends exhibit lower activation energies at each combustion stage compared with those of the base components, polyethylene and anthracite coal. Mixed-fuel combustion demonstrates synergistic reaction mechanisms. The proper blending of the feed materials cornstalk, polyethylene and anthracite coal can remarkably improve the characteristic of combustion.

期刊介绍： Thermochimica Acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application. The journal focuses on the research that advances physical and analytical science of thermal phenomena. Therefore, the manuscripts are expected to provide important insights into the thermal phenomena studied or to propose significant improvements of analytical or computational techniques employed in thermal studies. Manuscripts that report the results of routine thermal measurements are not suitable for publication in Thermochimica Acta. The journal particularly welcomes papers from newly emerging areas as well as from the traditional strength areas: - New and improved instrumentation and methods - Thermal properties and behavior of materials - Kinetics of thermally stimulated processes
