高温条件下的回火研究

Lightback at Elevated Temperature

本文介绍在高温条件下为获得使用第二族和第三族燃具检验测试燃气的实际火孔回火数据的试验设备及试验步骤。给出了在不同火孔长度与孔径比值条件下熄火孔径和极限孔径对试验结果使用计算机进行了处理,熄火孔径与温度之间关系的公式连同对进一步研究的方向的建议在文章中也给予介绍。

This paper describes the experimental equipment and precedure for obtaining lightback data representative of practical flamports for appropriate second and third-family appliance approval test gases at elevated temperatures. Quenching and limiting diameters are presented for a range of length/diameters ratios. Computer methods were applied to the results and the equations relating quenching diameter to temperature are given along with suggestions regarding the direction of future studies.
