径向浓淡旋流燃烧器用耐热抗磨中心扩锥试验研究

Testing and Study of Heat-resisting, Anti-abrasion Center Expanding Cone Used in Radial Concentrated-thin whirl Burners

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。

Through contrast and analysis of various materials used in center expanding cones,the heat-resiting,antiabrasion materials for center expanding cones are studied and determined.The operating practice of such materials in coal-fired power plants indicates that, the high temperature oxidized defromation of center expanding cones if small, antiabrasion property is good and operating duration is long.
