为模拟研究煤火燃烧污染物产出特征与燃烧工况的内在关联特性,设计并构建了一种煤加热氧化综合实验系统。该系统主要由炉体、热源装置、空压机、流量计、压差计及温度巡检系统等组成。基于该实验系统,采用COMSOL模拟分析了不同入口压力条件下炉体内温度分布及其随时间的变化趋势,其结果可为分析不同工况条件下煤氧化燃烧产物生成特征提供依据。
In order to simulate the inherent relationship between the output characteristics of coal-fired combustion pollutants and combustion conditions, a comprehensive experimental system of coal heating and oxidation was designed and constructed. The system mainly consists of furnace, heat source device, air compressor, flow meter, differential pressure gauge and temperature inspection system. Based on this experimental system, COMSOL simulation was used to analyze the temperature distribution and the trend over time under different inlet pressures. The results provide the basis for the analysis of the formation characteristics of coal oxidation combustion products under different operating conditions.
