摘要
为了描述双蓄热式环形加热炉在特殊结构下流动、传热和燃烧过程的特性,建立了非对称双蓄热式环形实验炉内流动、传热和燃烧过程的数学模型.湍流模型采用标准κ-ε双方程模型,燃烧模型采用平衡混合分数(PDF)模型,辐射传热模型采用离散坐标(DO)辐射模型.利用数值仿真软件进行了模拟计算,结果表明,炉膛内温度均匀性较好,一氧化碳的燃烧完全,二氧化碳的浓度在炉内分布均匀.
A comprehensive mathematical model of fluid flow, heat transfer and gas combustion in a reheating furnace was developed to describe the characteristics of double-regenerative rotary furnace with special structure. The standard κ-ε two-equation model was used for description of turbulent flow, the equilibrium mixture fraction probability density function （PDF） model for gas combustion,and the discrete ordinates （DO） model for radiation heat transfer. The numerical simulation showed that the hearth temperature was uniform, the combustion of carbon monoxide was adequate and the density distribution of carbon dioxide was even in the furnace.
