    The hopper 8 is provided with a pneumatic vibrator 29 fixed in its lower part. In another embodiment, is also provided with a cylinder 30.
    The control unit 4 includes an indicator 31, a flow sensor 32, a powder supply controller 33 and a carrier gas flow rate controller 34 in the tubes 17, a control valve 35.
    The installation works as follows.
    Powder is poured into the cavity of the hopper when the cover is removed 11, the lid is closed
    Through pipelines 20 and 28, gas is supplied from the control unit to pipes 19 and 27. A vibrator 29 is turned on. Gas flows into the cavity of the hopper only when the valve is opened in pipe 27. Gas flows through
    into tubes 19, passes through sieve filters installed in tubes (not shown). In a limited area at the opening of the filter 13, the powder goes into a liquid state, allowing it to pass freely through the filter at a speed proportional to the gas flow. 13 are commensurate with the size of the powder particles for their passage.
    A single source of gas through the flow sensor pipe 32 supplies the carrier gas and the tubes 17 through the pipelines 2, and the gas supply control valve 35 to the tubes 27 is adjusted so that it only passes the carrier gas when the carrier gas stops flowing through the tubes 17.
    The powder entering the chamber 16 is captured by the tubes 17 and through their central channels 18 through the carrier gas lines 5 is supplied to the burners 6.
    The rate of powder drift in each individual carrier gas stream is directly proportional to the gas stream.
    Located on the panel of the control unit 4. The indicator 31 is intended for instantaneous depressurization of the carrier gas entering the gas supply lines 2 to the tubes 17.
    The powder feed regulator 33 is a manual means for installing a pressure control valve 35 in a carrier gas source on one or more conduits 20 to the pipes 19.
    3
    When the regulator 33 is installed in a position to permit the passage of gas to the tubes 19, the pressure on the indicator 31 increases almost directly in proportion to the speed of the powder feed through the tubes 17.
    The flow sensor 32 is designed for current readings of the flow of carrier gas in the lines of pipelines 2, to the inlets to the tubes 17,
    The regulator FOR the flow rate of the gas controls the change in the orifice and the choice of the flow rate of the carrier gas supplied to the tubes 17.
    The installation allows at least one of the carrier gas supply lines of one powder supply device, as well as at least one
