The inner screening shall be cut on the scanner side and connected to ground at the flame controller. 内部的屏蔽层应该在扫描仪的一面切开,并且连接上火焰控制器的地线上。
Study of the influence regularity of inner and outer air amount of 3 channel burner on flame shape 三通道喷煤管内外风量对火焰形状影响规律的研究
From the results of experiments and theoretic analysis, it shows that the obstacle wrinkles flame front surface and enlarges the turbulence intension of unburned gas before flame and flame inner flow field. The flame acceleration is improved. 实验与理论分析表明,障碍物的存在引起火焰前锋褶皱度增大,提高了火焰前方未燃气体以及火焰内部流场的湍流强度,促进了火焰加速。
The high temperature zone is at inner side of OH zone for the diffusion flame, but both zones are approximately at the same position for the premixed flame. 对于扩散火焰,高温区在OH带内侧;而对于预混火焰,二者基本一致。
The flame-retardant, antistatic and high-strength plastics vane was prepared by the method of composite-reinforcement with mutiple layer of functional materials, with its inner core material having the functions of flame retardance and reinforcement, its outside lay material having flame retardance, antistatic and abrasion resistance. 采用多层功能材料复合增强方法制备了阻燃、抗静电、高强度尼龙叶片,其内芯材料具有阻燃、增强的功能,外层材料具有阻燃、抗静电及耐磨性。
Infrared thermal image devices currently available can only provide accumulative temperature images of a flame during the monitoring of the latter without the ability to present any information concerning the inner temperature distribution of the flame. 现有的红外线热像仪监测火焰时只能提供火焰累积温度图像,无法提供火焰内部温度分布信息。
Combustion efficiency is more influenced by inner/ outer secondary air vanes, but the influence of grade air which organize flow field and control flame is lower. 分级风对燃烧效率的影响较小,但对组织流场、控制火焰具有重要作用;内外叶片倾角对其燃烧效率的影响比较明显。
