Recovery Boiler Safety and Audits - TAPPI

Tube leaks are responsible for just over half of the smelt-water explosions and just under 40% of the total explosions. The common perception is this is by far the most important factor in recovery boiler safety, but the explosion problem is much broader than just tube leaks. Leak size matters. The likelihood and potential magnitude
