Abstract

A process and apparatus for the metered introduction of fine-grain materials, particularly pulverulent solid substances (i.e., coal dust) from a pressurized metering container which contains a supply of solid material, into an industrial furnace having a plurality of feed locations such as a blast furnace or cupola furnace is presented. The solid material is fed to the individual feed locations in a carrier gas stream through a conveying duct, the gas stream being highly charged with the solid material. The carrier gas is fed to the lower end section of the metering container in a flow which causes a local loosening in the lower section of the supply of solid material with the conveying ducts opening into the loosening region. The apparatus includes a metering container, which is designed as a pressure vessel and which is adapted to be filled at its upper end section with solid material to be fed to the furnace. The metering container includes at its lower end section a plurality of upwardly open chambers. At least one conveying duct leading to a feed location opens into each of the chambers. The conveying ducts are provided in each instance with a gas-permeable incident flow floor. Also, on the side of each conveying duct remote from the metering container a carrier gas duct for the carrier gas feed communicates therewith.
