Title:
POWDERED COAL SUPPLY DEVICE AND TOXIC TRACE ELEMENT ELUTION SUPPRESSION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/106796
Kind Code:
A1
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.
