Abrégé
A method for emptying a furnace floor from smelt in a black liquor recovery boiler when the black liquor recovery boiler is being shut down. The emptying can be started while smelt is still flowing in smelt spouts. The floor is emptied by sucking smelt from the furnace with a smelt eductor. A device for removing smelt and wash water from a furnace of a black liquor recovery boiler by means of suction. Negative pressure is generated in the device by conducting pressurized gas into a suction pipe of an eductor so that preheated pressurized gas is discharged in the discharge direction of smelt and wash water.
Classes IPC ?

The invention is also related to a device for removing smelt and wash water from a furnace of a black liquor recovery boiler by means of suction. Negative pressure is generated in the device by conducting pressurized gas into a suction pipe of an eductor so that preheated pressurized gas is discharged in the dis-charge direction of smelt and wash water.
