    Preventing Dry-firing in Boilers - PHCP Pros

    Mar 14, 2014 · Ironically, that’s the best outcome to this situation. The worst outcome occurs when a boiler operator sees that the boiler is out of water and then energizes another feedwater pump to restore water to the boiler. The water hits the glowing hot metal, flashes, and then expands 2,000 times its original volume, ripping apart the boiler tube sheet.

    Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or

    In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.
