焙烧炉燃烧器射流发散的分析与消除

THE CALCINER BURNER JET FLOW RADIATION'S ANALYSIS WITH ELIMINATES

通过将燃烧器喷嘴锥阀模拟为弹簧——质量——阻尼二阶系统,并分析燃烧器脉冲阀关闭时喷嘴锥阀关闭响应,从流体介质重油的稳态和瞬态两方面加以计算求解,通过建立流体介质的动量方程,伯努力方程,运动微分方程,得出喷嘴锥阀关闭响应时间与脉冲时间的关系,从而找出焙烧炉燃烧器射流发散的原因以及相应的措施。

Through the burner nozzle mushroom valve simulation is the spring- Quality --The damping second order system, and analyzes the burner pulse valve shuts down when the spray nozzle mushroom valve closure to respond, calculates from the fluid medium heavy oil＇s stable state and the transient state two aspects solves, through the establishment fluid medium＇s momentum equation, the primary equation, the movement time and the pulse time differential equation, obtains the spray nozzle mushroom valve closure response relations diligently, thus discovers the calciner burner jet flow radiation the reason as well as the corresponding measure.
