摘要
在冷模试验台上利用热线风速仪对屏区中气流流动情况进行了详细的测量 ;分析了分隔屏和后屏在烟气偏差形成中所起的作用 ;还提出了 3个屏结构改进措施并进行了相应的试验 ,使水平烟道中烟气偏差状况得到了较大改善。图 6表 2参
The velocity fields in the panel zone and horizontal gas pass were carefully measured in an isothermal model with a 600MW tangentially fired boiler. The influence of the panel and rear panel superheaters on velocity distribution in the horizontal gas pass was researched. Three improving measures were provided and some experiments were done for decresing the coefficient of velocity deviation in the horizontal gas pass. The results of experiments showed that three improving measures were effective. Figs 6, tables 2 and refs 2.
