摘　　要：根据天然气冲天炉结构特点设计了一种富氧高燃烧强度的燃烧器并建立燃烧器燃烧的物理模型和数学模型,利用CFD软件Fluent模拟研究了不同预热温度以及不同空气预混比例对燃烧温度、火焰长度变化等的影响规律,为以后该类型燃烧器的设计提供了理论依据。A high-intensity oxygen-enriched natural gas burner was designed based on the structural characteristics of natural gas cupola,and its physical and mathematical models of flame were established.The CFD software fluent was used to study the influence of different preheating temperature and different air premixed ratio on the combustion temperature and flame length.The results provide theoretical basis for the design of this type of burner in the future.

关 键 词：富氧燃烧 火焰长度 数值模拟 天然气冲天炉
