  • Melting tank with a closable batch loading channel
    Patent number: 6581652
    Abstract: A melting tank with a batch loading channel, with a channel covering having an exhaust gas flue and a loading opening that can be closed by a loading door or flap during operation of the melting tank and the loading opening can be opened for loading the batch. Emissions and service life improvements can be achieved because during operation of the melting tank, a constant air stream is introduced into the loading channel by nozzles in the closed loading door or flap. While loading the batch, the loading door or flap is moved sufficiently far so that the nozzles are moved out of the region of the loading channel, and the loading door or flap covers the region underneath the channel covering with a suction device. A region of the loading opening underneath the channel covering is opened for a loading device.
