What Makes Water Tube Boilers Safer Than Fire Tube Boilers

When fire tube boilers run low on water, the metal in the boilers shrinks. In such an instance, if cold water is sent into the boiler, the metal could quickly expand, causing an explosion. However, with less water present in a water tube boiler, if anything goes wrong, the explosion won't be anywhere near as serious as it would be in a fire
