接触圈
切圆
Examples
- Conversely , if a person confined to the same circle of contacts , may be on the psychological development of a one - way and narrow - minded flaws
反之，如果人的交往局限于同性圈子，心理发展就可能会有某种单向性和狭隘性的缺陷。 - These measures are as follows : shorten the primary wind intervals to improve thermal load of the burner ; reduce the size of hypothetical circle of contact to prevent the flame from splashing ; use nozzles with larger height / width ratio to increase the effusive rigidity , so as to increase the jet flow depth of secondary wind into the main jet flow ; use a higher primary wind velocity to increase its jet flow rigidity ; use a special flame holder structure of the primary nozzle , so as to improve
这些技术措施主要有:缩小一次风间距以提高燃烧器区域热负荷;缩小假想切圆防止火焰刷墙;采用高宽比较大的二次风喷口以增加射流刚性,提高二次风射流进入主射流的深度;采用较高的一次风速来提高一次风射流刚性;一次风喷口采用特殊稳燃结构;提高下二次风的托粉能力。 - These results show that since the existent defects of combustion device structure and its hypothetical circle of contact , these make a poor primary and secondary wind rigidity in operation and a too big actual circle of contact . in addition , the coal used is extreme prone to burn and reside in boiler . under such a condition , the coal powder ignites earlier in a short time and short distance when it leave the jet - combustioning device , and splashes the water cooler , eventually this results in a burned coal residue in boiler
针对宏伟热电厂410t / h燃煤锅炉严重结渣问题,对燃煤的结渣性、炉内温度工况及空气动力工况等进行实验研究,由于燃烧器结构和假想切圆选择的缺陷,使得锅炉在正常运行时,一、二次风刚性较差,实际切圆过大,加上目前燃用煤质属于极易燃、易结渣煤质,致使煤粉在离开喷燃器很短的时间、较短的距离内开始着火,并冲刷水冷壁,最终造成炉膛结渣。
