rear arch

Combining the layer momentum integral equations with the velocity distribution characteristics summarized from modeling experiment under the stoker arches, the theoretical formula of the friction resistance of rear arch surface is deduced and educed.

根据边界层动量积分方程结合拱区模化试验整理的拱区速度分布特性，对火床炉后拱面摩擦阻力进行了理论推导，得出了计算表达式。

The results of study indicate that the vortex arch can effectively increase the suction and transport quantity of gas flow from a rear arch to a front one, contributing to an increase in the front arch temperature.

结果表明，涡流拱能有效地增加后拱气流向前拱的卷吸输送量，有助于提高前拱温度。

Influence of Rear Arch of Grate Furnace on Agglomerating Coal

层燃炉后拱对煤结焦的影响

Note the sucked-in contour at the lower door ahead of the rear wheel arch; note also the eye-fooling black rocker panels ( the panels under the doors) that helps control spray and manage underbody aero without compromising that athletic waist.

请注意后轮拱罩前面车门下部的吸入式轮廓，也请注意给人错觉的黑色踏脚板（门下的踏板）。踏脚板控制溅水，控制车底气流，同时又不牺牲腰部的美感。

This paper synthetically analyses the reason of the tube explosion occured on rear arch by mean of P& C inspection, and puts forward improvement suggestion.

通过理化检验，综合分析水冷壁后拱管爆管原因，并提出改进意见。

Secondary air under arch turned upwards after it entered front wall region of the furnace. Then it flowed towards rear wall region under arch.

前墙拱下二次风喷入炉膛内即转折向上，冲向后墙拱下区域。

The experimental results show that the large size controllable vortex above the stock produced by dipole vortex device gets up the transfering ability of high temperature gas to the area of fuel ignition, and about 3~ 4 times than the conventional rear arch.

试验表明，偶极子涡流器在炉排上部产生的大尺度可控旋涡提高了向燃料着火区输送高温烟气能力，约比传统后拱的输送能力提高2～3倍。
