Zusammenfassung:	A powder conveyance device and a char collection device are each provided with: conveyance piping (112) serving as a powder conveyance line which can convey char at a predetermined tilt angle by allowing the char to fall by gravity; a first porous plate (101) having a predetermined aperture ratio and disposed along the conveyance piping (112); a second porous plate (102) having a higher aperture ratio than the first porous plate (101) and disposed along the conveyance piping (112) at a position above the first porous plate (101); and an assist gas supply device (103) for supplying assist gas to the conveyance piping (112) through both the first porous plate (101) and the second porous plate (102). As a result of this configuration, powder and char can be efficiently and appropriately conveyed.
