PURPOSE:To supply powder in a satisfactory state under high pressure by providing a piston which forces upward the powder supplied into an inclined tank and a vane for discharging said powder so that the sticking of the powder on the wall surface and the bridging thereof can be prevented. CONSTITUTION:A device is constituted of a tank 5 whch is provided inclinedly, a piston 17 which is provided freely slidably along the axial center direction of the tank and forces upward powder 9, a powder discharging vane 20 which discharges the powder 9, a powder supplying valve 10, a powder discharging valve 14, an steam lines 23, 24 for pressure equalization. A powder supplying pipe 6 and a powder discharging pipe 7 are connected to said tank 5. The lines 23, 24 are connected to the top and bottom ends of the tank 5 and steam for pressure equalization is introduced behind the vane 20 and the piston 17. |
