  • Patent number: 4544138
    Abstract: During the charging of a blast furnace with a new raw material, gas with a high dust content enters and pressurizes the storage bin. This pressurized gas is fed to one end of a temporary storage chamber in the form of an elongated tube having a discharge opening with a noise attenuator at the other end. When the storage tube is filled, it is connected to a low pressure suction device for removing the dust laden gas from the storage tube. The equipment is described with twin bins and alternating discharge therefrom using the same temporary storage tube.
