< 2011-5-3 · Several events can cause unplanned shutdowns of recovery boilers. One of the most extreme causes is the cracking of boiler tubes. When cracks in the boiler tubes extend deep enough to allow water and steam to leak into the recovered molten pulping chemicals (smelt) on the floor of the boiler, a large explosion can occur. Cracked tubes can take days to weeks to repair and result in significant
