摘要

采用热重分析法研究了不同升温速率下油泥焦、褐煤及其混合物燃烧特性，并利用Kissinger-Akahira-Sunose（KAS）、Flynn-Wall-Ozawa（FWO）和Friedma（FR）等方法计算其燃烧动力学参数。结果表明，油泥焦燃烧主要是固定碳燃烧过程，而褐煤燃烧是挥发分和少量固定碳连续燃烧的过程。褐煤比油泥焦具有更好的燃烧特性，平均活化能更低。油泥焦和褐煤共燃过程中存在明显的协同促进作用，当混合燃料中褐煤占比为75%时协同促进效应达到最强。通过比较KAS、FWO和FR的结果发现，FR法能够更好地体现反应变化的趋势，而KAS法和FWO法的结果具有较高的准确性。通过比较油泥焦和褐煤共燃动力学参数的理论计算值与实验计算值发现，利用热重分析预测混合燃料的燃烧性质具有较高的可靠性，对油泥焦与褐煤共燃技术的应用具有重要的指导作用。

Abstract

The combustion characteristics of sludge coke

lignite and their mixtures at different heating rates were studied by thermogravimetric analysis. Their combustion kinetic parameters were calculated by Kissinger-Akahira-Sunose (KAS)， Flynn-Wall-Ozawa (FWO) and Friedman (FR) methods. The results indicated that the combustion of the oil sludge char was mainly a fixed carbon combustion process

while that of the brown coal was characterized by a process of continuous combustion with a large amount of volatile and little fixed carbon. Compared with the combustion of the oil sludge char

the brown coal had a better combustion performance and its average activation energy was much lower. There was a significant positively synergistic interaction in the co-combustion process of the oil sludge char and the brown coal. When the proportion of brown coal in the blends reached up to 75%

the positively synergistic interaction effect was the strongest. The FR method better reflected the trend of the process

but its generated results were less accurate compared to that from KAS and FWO models. By comparing the theoretical and experimental values of the co-combustion kinetic parameters of the sludge char and the brown coal

it was found that application of thermogravimetric analysis to predict the combustion properties of the mixed fuel exhibited a high reliability

which can thus play an importantly guiding role in the application of the co-combustion technology of the oil sludge char and the brown coal.
