摘　　要：该文对弯管式浓淡煤粉燃烧器分离及阻力特性进行了实验研究，导出此种燃烧器冷态模化的相似准则。采用多元非线性回归理论，分析了大量的实验数据，得出了关于此种燃烧器分离及阻力特性的回归方程；得出的规律性是明显的。该文得出的方程和结论，完全可以在相应条件下供此种燃烧器的设计研究者作参考之用。Abstract: Based on experimental studies of the segragation and flow resistance properties of bent tube type dense/lean pulverised coal burners,the paper deduces a cold state modeling criterion.Making use of the regression theory of nonlinear multivariables and based on the analysis of multitudious experimental data,a regression formula showing clear functional relationships of these characteristics is obtained.The formula and conclusions presented in the paper may serve as a valuable reference for designing and researching such burners under relevant conditions.
