| 摘 要： | 对大气式燃烧器，当燃烧器头部燃烧区产生负压时，其自动调节特性会受到影响。分析了燃烧器引射能力与燃烧区负压的关系，结合典型案例，量化分析了燃烧区负压对燃烧器一次空气系数的影响。大气式燃烧器引射的一次空气量对燃烧区负压非常敏感，负压会增大一次空气系数。

| Abstract: | The self-proportioning characteristics of atmospheric burners are affected when negative pressure occurs in the combustion zone of a burner. The relationship between the injection capacity of a burner and the negative pressure in combustion zone is analyzed. The influence of the negative pressure in combustion zone on the primary air coefficient of the burner is quantitatively investigated. The primary air injected by an atmospheric burner is sensitive to the negative pressure in combustion zone, and the negative pressure should increase the primary air coefficient. |
