1)  subgrade filler
基床填料
2)  packed bed
填料床
1.

结合气固传热方程和热平衡方程,求得了竖炉在某个产量下所需的焙烧风量,并运用填料床阻力特性规律研究了如何能够将充足的焙烧风量鼓入球团料层这一问题。
2.
According to the dynamics of gas-solid packed beds, a mathematical model of gas flow in an air internal vertical chan-nels (IVAC)/drying bed pelletizing shaft furnace (PSF) is developed with certain boundary conditions.
根据气固填料床动力学,建立了“导风墙-烘干床式”球团竖炉内气体流动的数学模型·运用自编程序数值求解炉内速度场,研究炉内气体流动的基本规律,探讨竖炉操作参数对炉内气体流动的影响规律·结果表明:焙烧风和冷却风在进口处呈放射状,之后斜向上或斜向下分别流入焙烧-预热带和导风墙内;整个均热带内气流较为薄弱;炉内存在三种气流分流的可能,流入风量比是决定气流分流的最主要因素,其中,流入风量比增加,焙烧风下行趋势增大,而冷却风上行趋势减小;临界流入风量比主要取决于结构参数和料层情
3.
Based on the theory of gas/solid packed beds, the pelletizing shaft furnace(PSF) of Jinan Iron & Steel Co.
以济钢球团竖炉为背景,将气固填料床理论和实验相结合,系统研究了炉内粉矿的成因、危害及控制手段·结果表明:竖炉粉矿量为干球与成品球团流量之差,其三种表现形式为爆裂粉矿、落下粉矿及碰撞粉矿,沉积粉矿循环造成炉内部分粉矿难以排除炉外;从干燥带到均热带,粉矿生成速率逐渐减小,粉矿生成总量逐渐增加,但在导风墙下沿处,由于沉积粉矿循环造成此处的粉矿总量骤然下降;炉内粉矿增加,降低了竖炉利用系数,增加了球团工序能耗;控制炉内粉矿的有效措施是实施炉内除尘,即将含尘气体从导风墙下沿引出,经过重力除尘后返回炉内以强化生球干燥
