Abstract:
The invention is related to a method for emptying a furnace floor in a soda recovery boiler when the soda recovery boiler is being shut down. The emptying may be started while smelt is still flowing in smelt spouts. The floor is emptied by sucking smelt from the furnace with a smelt eductor. The invention is also related to a device for removing smelt and wash water from a furnace of a soda recovery boiler by means of suction. Negative pressure is generated in the device by conducting pressurized gas into a suction pipe of the eductor so that the pressurized gas is discharged in the discharge direction of smelt and wash water.
