| Claim: | 1. A cleaning unit for cleaning at least two smelt spouts of a recovery boiler one at a time, the cleaning unit comprising: a motorized cleaning member comprising a cleaning tool and configured to clean a first smelt spout of a recovery boiler; and a motorized transfer device configured to transfer the cleaning unit including the motorized cleaning member and cleaning tool from a location of the first smelt spout to a location of a next, second smelt spout of the recovery boiler, wherein the motorized cleaning member comprising the cleaning tool is further configured to clean the second smelt spout. |
| Claim: | 2. The cleaning unit according to claim 1 , wherein the transfer device is configured to transfer the cleaning unit parallel to a wall of the recovery boiler. |
| Claim: | 3. The cleaning unit according to claim 1 , further comprising: a monitoring device configured to identify a plugged smelt spout or a smelt spout about to be plugged. |
| Claim: | 4. The cleaning unit according to claim 1 , further comprising: an air nozzle cleaning device configured to clean air nozzles of the recovery boiler. |
| Claim: | 5. The cleaning unit according to claim 1 , wherein the cleaning unit is configured to travel along a guiding structure from the first smelt spout to the second smelt spout to clean the smelts spouts one at a time. |
| Claim: | 6. The cleaning unit according to claim 1 , wherein the recovery boiler comprises further smelt spouts, and wherein the cleaning unit is configured to travel along a guiding structure from one smelt spout to another smelt spout to clean the smelts spouts one at a time. |
| Claim: | 7. A cleaning apparatus for cleaning at least two smelt spouts of a recovery boiler one at a time, the cleaning apparatus comprising: a cleaning unit having a motorized cleaning member comprising a cleaning tool and configured to clean a first smelt spout of a recovery boiler; a motorized transfer device configured to transfer the cleaning unit including the motorized cleaning member comprising the cleaning tool from a location of the first smelt spout to a location of a next, second smelt spout, wherein the motorized cleaning member comprising the cleaning tool is further configured to clean the second smelt spout; and a guiding structure along which the cleaning unit is configured to travel to transfer from the first smelt spout to the second smelt spout to clean the smelts spouts one at a time. |
| Claim: | 8. The cleaning apparatus according to claim 7 , wherein the guiding structure is horizontal and parallel to a wall of the recovery boiler. |
| Claim: | 9. The cleaning apparatus according to claim 8 , wherein the guiding structure is connected to the recovery boiler. |
| Claim: | 10. The cleaning apparatus according to claim 7 , wherein the cleaning unit is suspended from the guiding structure. |
| Claim: | 11. The cleaning apparatus according to claim 7 , further comprising: a carriage configured to move the cleaning unit along the guiding structure, the carriage comprising at least a part of the motorized transfer device, wherein the cleaning unit is connected to the path via the carriage. |
| Claim: | 12. The cleaning apparatus according to claim 7 , wherein the recovery boiler comprises further smelt spouts, and wherein the cleaning unit is configured to travel along the guiding structure from one smelt spout to another smelt spout for cleaning the smelts spouts one at a time. |
| Claim: | 13. The cleaning apparatus according to claim 7 , wherein the guiding structure comprises a rail or a guide bar. |
| Claim: | 14. The cleaning apparatus according to claim 7 , wherein the recovery boiler further comprises a protective wall, wherein the protective wall and a wall of the recovery boiler define a smelt spout area therebetween, and wherein the cleaning apparatus is located in the smelt spout area. |
| Claim: | 15. An industrial robot for cleaning at least two smelt spouts of a recovery boiler one at a time, the industrial robot comprising: a motorized cleaning member comprising a cleaning tool and configured to clean a first smelt spout of a recovery boiler; and a motorized transfer device configured to transfer the cleaning unit including the motorized cleaning member comprising the cleaning tool from a location of the first smelt spout to a location of a next, second smelt spout, wherein the motorized cleaning member comprising the cleaning tool is further configured to clean the second smelt spout. |
| Claim: | 16. The industrial robot according to claim 15 , further comprising: a carriage configured to move the industrial robot along a guiding structure and comprising at least a part of the motorized transfer device, wherein the industrial robot is connected to the guiding structure via the carriage. |
| Claim: | 17. The industrial robot according to claim 15 , wherein the industrial robot is configured to travel along a guiding structure from one smelt spout to another smelt spout to clean the smelts spouts one at a time. |
| Claim: | 18. The industrial robot according to claim 15 , wherein the industrial robot is further configured to open a hatch, a door or a wall. |
