Device for introducing dosed quantities of pulverized solid materials into a carrier gas stream |
摘要 |
A device for introducing dosed quantities of pulverized solid materials into a carrier gas stream is presented. The device is particularly suitable for injecting solid fuels into a shaft furnace during metal refining. The device comprises a housing having oppositely disposed inlet and outlet radial apertures therethrough. The inlet radial aperture is connected to a container holding pulverized materials. Coaxial inner and outer sleeves, at least one of which is capable of rotation, are located within the housing. Upon rotation of a sleeve, pairs of oppositely disposed slots provided on each sleeve will align and overlap with each other and with the pair of oppositely disposed apertures to define variable sized passages. A cheek positioned on one end of the housing has a cylindrical extension portion which extends axially into the inner sleeve and extends across the inlet and outlet apertures. The extension portion includes a channel therethrough which is axially aligned with the first and second aperture means and is also connected to a source of pressurized fluid.
