摘　　要：介绍了国内石油焦煅烧回转窑三次风供风系统结构及发展现状,对风嘴保温材料脱落及烧损等问题进行了分析,进一步介绍了在引进METSO大型回转窑的风嘴锚固件上布设"龟甲网"的创新实践,对有效解决三次风嘴保温层脱落及延长风嘴使用寿命,提供了新的改良途径。The structure and development status of tertiary air supplying air system in domestic petroleum coking kiln were intro- duced, and the questions of falling insulation materials and burning in air nozzle were analyzed. Further innovation practice of laying shells network air nozzle anchoring parts of the kiln, which was introduced from METSO, was adopted in a domestic company. An improved approach which can effectively solve the tertiary air insulation layer off and prolong the life of the air nozzles was put forth.
