Title: Improvements in Boilers, Evaporators, or Heaters.
Filed: 1898-03-04
Granted: 1898-06-11
Abstract: 5325. Soc. Anonyme du Temple and BrilliÚ, H. March 4. Multitubular boilers; priming, preventing; steam separators.-Consists of a boiler or evaporator for heating water and other liquids to obtain a supply of distilled water, or dry steam, or for other purposes. The liquid is fed through holes in pipes 1 into a cylindrical casing 2, at the bottom 3 of which it is deflected upwards by a projecting part 4 into a casing 6 in which it is heated and evaporated by serpentine tubes 5 through which steam or other heating-agent passes. Priming is prevented by the shape of the upper part 10 of the casing 6, and by downwardly-projecting pieces 9, 11. The steam or other vapour emerges above the level of the liquid in the outer casing, and, after passing baffle-plates 13, enters a steam separator 14. This is in the shape of a spiral coil from which dry steam emerges through the pipe 17, while the separated liquid is returned through the pipe 18. Concentrated liquid may be drawn off through pipes 12.
