  • Method of preventing vapor explosions caused by contact of two liquids having different temperatures
    Patent number: 4194124
    Abstract: Vapor explosions caused by contact of two liquids having differing temperatures, such as occurs in a chemical recovery furnace containing molten smelt when water accidentally contacts the molten smelt, are prevented by subjecting the water/molten smelt interface to sufficient radiation to prevent such explosions by creation of multiple bubble nuclei which result in non-explosive nucleate boiling.
