Abstract

Method and apparatus for use in a system which conducts a mixture of granular solids, such as preheated coal particles, and carrier gas, such as steam, to a plurality of enclosures, such as individual coke ovens of a coke oven battery. The mixture passes through a primary conduit and at least a portion of the mixture is diverted from the primary conduit by diverter means to a plurality of branch conduits. Each of the branch conduits leads to one of the enclosures. The method includes: removing a portion of the carrier gas from the mixture in the branch conduit prior to introducing the granular solids into the enclosure; and returning the removed portion of the carrier gas to the primary conduit downstream of the diverter means. The apparatus of the present invention includes a bleed-off conduit arranged between each of the branch conduits and a portion of the primary conduit downstream of the diverter means.
