直立螺旋—气固喷射器小型给粉装置

Vertical Spiral-Gas Solid Injector Small Powder Feeder

简单介绍了几种复合式给粉装置的工作原理,针对其存在问题设计了一种新颖的为小型煤粉燃烧器可连续、稳定提供燃料的立式螺旋-气固喷射器给粉装置,通过实验数据分析,给出了该装置的关键设计参数粉料填充系数φ值、主要技术参数和结构尺寸等。

This article outlines the working principles of several types of combined powder feeders.And to solve the problems existing in such feeders,a new vertical spiral-gas solid injector powder feeder is designed,which can provide continuous and stable fuel to small coal powder burners.Through analysis of experimental data,it gives the key design parameter of the feeder,the powder packing factor φ,main technical parameters and structural dimensions,etc.
