Abstract

The present invention provides a powdered coal supply device with which the ratio between coal and an elution prevention agent for toxic trace elements can be uniform. This powdered carbon supply device (10) is provided with: a coal bunker (11) in which coal is stored; a coal feeder (12) that has therein a transportation conveyor (12c) that transports the coal supplied from the coal bunker (11); and a coal pulverizer (14) that pulverizes the coal charged from the coal feeder (12) and generates powdered coal. The coal feeder (12) is provided with a box-like frame (12f) and an elution suppression agent adding device (13). The frame (12f) has a coal dropping port (12s) from which the coal is discharged and which is open at a lower part of another end part. The elution suppression agent adding device (13) can drop, toward the coal dropping port (12s) in the frame (12s), an elution suppression agent Ea for suppressing the elution of toxic trace elements from combustion residue of the coal.
