    摘要: A method and an apparatus for making a mineral melt having a cyclone furnace and a separating cyclone, the apparatus having a device for supplying pre-heated particulate mineral material from a bottom of the separating cyclone to an inlet of the cyclone furnace. A material receiving conduit adapted for receiving the pre-heated particulate mineral material from the bottom outlet of the separating cyclone, in which the material receiving conduit has a first pressure. An outlet conduit supplying the particulate mineral material to the inlet of the cyclone furnace having a second pressure, wherein the second pressure is higher than the first pressure, and the particulate mineral material is fluidised and flows from the material receiving conduit to the outlet conduit. A gas-lock valve is provided between the material receiving conduit and the outlet conduit.

    摘要: An apparatus for the production of a mineral melt burns combustible material in the presence of inorganic material to form a melt. The apparatus includes a circulating combustion chamber which receives a fuel, pre-heated mineral material and a combustion gas so as to melt the mineral material and generate exhaust gases which are separated from the melt. The gases pass through an exhaust pipe to a conduit of a heat exchange system. The apparatus includes a quenching hood for quenching the exhaust gases by drafting a cooling fluid, such as ambient air, into the flow of exhaust gases around the exhaust pipe, and wherein the exhaust gases exit the exhaust pipe inside the hood.
