Six weeks later, the same boiler goes down again. Different tube, same bank, same story. This is usually the point where operators start asking the wrong question. They ask which tube failed. The question that actually stops the next outage is why this boiler keeps producing failures in the firs

The True Nature of Boiler Disasters Every experienced boiler engineer has seen the aftermath. The drum ruptured. Fragments travelled as projectiles. The pressure wave demolished the control room wall. Steam at temperatures well above the safe operating range for the tube material filled every adjacent space within seconds. And when the investigation team finally arrived days later, once the site was safe, the first thing they found was a tube wall that had thinned well below
