Improvements in the Heating of Fluids

11,062. Mond, R. L. May 14. Steam generation by molten metal.-Relates to the heating of fluids for generating steam or vapour, by passing through the fluid a heated molten metal or alloy. The metal or alloy, with a fusing point below the temperature to which the fluid has to be raised and a boiling point above that temperature, is heated by direct contact with flame or hot gases. When applied to a steam boiler, the heating-substance may be forced by automatic feeders into the boiler, and discharged at the bottom and raised to the heating-chamber to be again fed into the boiler.
