Resumo
The induration furnace is one of the most important devices in the pellet production
system. It is responsible for ensuring the quality of pellets produced, since a high
level of thermal energy is necessary to reach the physical properties needed. Therefore,
the refractory lining performance is important to guarantee the quality of pellets and
to avoid thermal losses. Minor failures in the refractory lining may result in serious
damage, if it not previously identified and repaired. This article was written to explain
a preventive technique to identify and repair such minor issues with the refractory lining
before escalation. The use of this technique in the proper frequency may result in
furnace life cycle extension.
