Abstract

Small, pourable particles of comminuted coal for coking purposes are gravity-discharged into a stream of hot gas flowing upwardly in a flight stream tube, in a direction inclined and generally opposite to the gas flow direction. Just prior to entry into the gas stream the particles are fluidized so that, on being entrained by the gas stream, they will become uniformly distributed throughout the cross-section of the same. A method and an apparatus are disclosed.
