摘要
将焚烧炉划分为加热干燥区、热解区、残炭燃烧区、挥发分燃烧区、辐射传热区 ,使建立的热力模型比 Essenhigh模型更接近实际过程。对各区域物理化学过程进行了较系统的分析 ,得到了稳定完全燃烧时 ,固体垃圾和可燃气在各区域所需的时间。结果表明 :加热和热解对整个焚烧过程起控制作用 ;保证挥发分的完全燃烧 ,是组织好燃烧工况的关键。
Some fields,such as drying by heating,devolatilization,char burning,volatiles burning,radiative heat transfer were divided in waste incinerator,thus making thermodynamic model more approaching to the actual process than Essenhigh model.The physical and chemical processes in these fields were analyzed respectively and systematically,the time of solid waste and fuel gases staying in furnace for wastes stable and complete combustion in these fields were obtained.The results showed that the heating and devolatilization played an important role in the total incineration process,and the volatiles complete combustion was the key of adjusting the burning conditions.
