齿形中心扩锥对旋流燃烧器气固流动影响的PDA试验研究

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.

径向浓淡旋流燃烧器用耐热抗磨中心扩锥试验研究

通过对中心扩锥采用各种材质对比分析，研究确定耐热抗磨中心扩锥材质。经过电厂运行实践表明，该中心扩锥高温氧化变形小、抗磨性好、使用寿命长。
