Challenges |
- Recovery boiler was operating with little to no bed, exposing the floor tubes and increasing the wear rate of floor tubes
- Excessive black liquor was present on the boiler walls, increasing the wear rate of the wall tubes
- Personnel changes in operations and maintenance roles created an increased demand for training
