Recovery Boiler Leak Indication

Recovery boilers are a critical component in the economical and safe operation of a modern kraft paper mill. Unscheduled, unnecessary downtime puts severe pressure on other mill operations which can reduce overall mill profitability. However, the possibility for smelt/water interaction and resulting boiler explosion as a consequence of tube failure makes the operations staff likely to conduct an ESP (Emergency Shutdown Procedure) on a unit at the slightest sign of a leak.
