摘要

利用热重分析仪对污泥在不同氧浓度下进行了热解和燃烧试验

分析了氧浓度对污泥燃烧特性的影响。研究结果表明

随着氧浓度的升高

整个燃烧过程的平均失重速率逐渐上升;低温段的失重速率随氧浓度升高而逐渐提高

失重极大值不断增大且出现时间提前;高温段的平均失重速率不断提高

在氧浓度50%时达到最大值

失重极大值逐渐减小而出现时间提前。污泥着火温度随氧浓度上升而有所降低。

Abstract

By using the thermogravimetric analyser

the pyrolysis and combustion test of sludge under different oxygen concentrations has been carried out

the influence of oxygen concentration upon the combustion characters of sludge being analysed.Results of study show that the average weight loss speed in the whole combustion process increases gradually as the oxygen concentration rises

the maximum value of weight loss increases continuously and appears earlier;the weight loss speed in high temperature stage continuouly increases and reaches maximum value when the oxygen concentration being 50%;the maximum value gradually reduces

and appears earlier.The ignition temperature decreases slightly as the oxygen concentration increases.
