The thermal characteristics and kinetics of paper sludge, rice straw and their blends were evaluated under combustion condition. The paper sludge was blended with rice straw in the range of 10-95 wt.% to investigate their co-combustion behaviour. There was significant interaction between rice straw and paper sludge in high temperature. The combustion of paper sludge and rice straw could be divided into two stages. The value of the activation energy obtained by the Friedman and the Ozawa-Flynn-Wall (OFW) first decreased and then increased with the conversion degree rising. The average activation energy did not monotonically decrease with increasing the percentage of rice straw in the blends. When the percentage of rice straw in the blends was 80%, the value of the average activation energy was the smallest, which was 139 kJ/mol obtained by OFW and 132 kJ/mol obtained by Friedman, respectively.
在燃烧条件下,评估了纸污泥、稻草及其混合物的热特性和动力学。将纸污泥与稻草按 10-95wt.%的比例混合,研究其共燃烧行为。在高温下,稻草和纸污泥之间存在显著的相互作用。纸污泥和稻草的燃烧可以分为两个阶段。通过 Friedman 和 Ozawa-Flynn-Wall(OFW)方法得到的活化能值随转化率的升高先降低后升高。通过 OFW 和 Friedman 方法得到的平均活化能值并非随混合物中稻草比例的增加而单调降低。当混合物中稻草的比例为 80%时,平均活化能值最小,OFW 法为 139kJ/mol,Friedman 法为 132kJ/mol。
