    Apr 06, 2015 · This theory hypothesized that low water allowed a boiler plate to be exposed to the fire, overheat and turn red hot. Then, when water struck the plate, it instantly turned to steam over pressurizing the boiler and resulting in an explosion. In addition, they believed that much of the energy was in the steam. An excess of steam was often cited.Learn More
