| 摘 要： | 1前言旋流燃烧器依靠高温回流区做为稳定的热源，使煤粉气流及时着火并稳定燃烧，燃烧器单独组织燃烧，不互相影响，燃烧器区域的气固流动特性决定了燃烧器的性能。燃烧器的喷口结构对其气因流动特性有重要影响山。本文提出了齿形中心扩锥结构（如图l所示）。2实验方法及结果分析试验采用三维激光粒子动态分析仪（简称三维PDA），实验台系统主要由送风机、吸风机、给粉机、燃烧器模型、试验段、旋风分离器等组成，试验段为一竖直放置的筒体，直径为4800mm，燃烧器模型安装在简体上部中心位置，最外层扩口端部与筒体内壁平齐，沿射流流动方…

| Abstract: | Structure of gear-shape (GS) central baffle was put forward for the first time in pulverized coal swirl combustion technology. Profiles of air and particles velocities, particle concentration and particle diameter with a GS central bafle swirl burners had been measured with a three-component PDA system in a gas-particle two phase test facility, in contrast, so did a common baffle swirl burner. Effects of GS central baffle on gas-particle flows had been obtained, influences on burners' ability had been analysed, and results of the industry use had also been given. |
