The most common way to repair a hot spot involves high costs. Often the unit has to shut down (unplanned shutdown). An internal inspection and refractory repair of the unit is only possible after a cooling-down period. Usually a scaffolding is needed which has to be constructed and dismantled after the repair. All in all, an unplanned downtime of more than a week with high and unforeseen costs.
There are two different types of hot spots. The first type are relatively small hot spots due to irregularities in the refractory lining which causes damage to the lining. The second type are the hot spots which occur because the refractory lining is damaged over a larger area (or areas). Usually it is clear which type of hot spot it is. When in doubt, a thermal scan can be made to find out what the overall temperature and the size of the hot spot is. (See the picture on the right)
The second type of hot spots needs a different and more complicated approach. A special technique is used to completely fix the refractory lining.
