Title:
POWDER TRANSPORTING FACILITY AND POWDER TRANSPORTING METHOD
Document Type and Number:
Japanese Patent JP2020083569
Kind Code:
A
Abstract:
To prevent blockage of a transport pipe while reducing a gas used amount.SOLUTION: A powder transporting facility 10 includes: a storage tank 11; a powder cutting device 12; a gas supply source 15; a transport pipe 16; a solid-gas ratio setter 17 which sets a solid-gas ratio in a ratio of a limitation solid-gas ratio of gas transportation of powder of 10% or more and 90% or less; a solid-gas ratio controller 20 which controls a gas flow rate and/or powder flow rate so that a solid-gas ratio actual value becomes a solid-gas ratio set value; and first blockage prevention means which increases a transport gas flow rate and/or reduces a powder flow rate on the basis of blockage possibility of the transport pipe 16, and thereby reduces the solid-gas ratio in the transport pipe.SELECTED DRAWING: Figure 1
