利用同步热分析仪研究碱解污泥的燃烧特性
Investigation on the combustion characteristics of alkali-decomposed sludge using simultaneous thermal analyzer
摘要
Abstract
In this paper, the characteristics of combustion and dynamic characteristics of the alkali-decomposed sludge were investigated using TGA/DSC simultaneous thermal analyzer. The results show that the weight loss process of the alkali-decomposed sludge includes three stages. The addition of alkali results in the decrease of ignition temperature of sludge and the increase of the temperature of burnout. Along with the content of alkali increasing, the combustion heat of sludge increases at the second stage, and the combustion heat decreases at the third stage, as a result, the total combustion heat decreases. At the second stage of weight loss of sludge, when the content of alkali increases, the activation energy before the weight loss peak increases, and the activation energy after the weight loss peak decreases. This study provides some basic data for the resource utilization of the dewatered sewage in the urban sewage treatment plant, especially for the application of sludge as industrial fuel.关键词
