Abstract
Abstract A GROUP OF VERTICALLY DISPOSED HORIZAONTALLY ELONGATED HOLLOW HEATING PLATES DISPOSED IN THE BOTTOM PORTION OF A HORIZONTALLY ELONGATED VESSEL WHICH HAS AN END WALL PROVIDED WITH A STEAM CHEST AND WITH CONDENSATION COLLECTING MEANS. EACH HOLLOW HEATING PLATE IS PARTITIONED TO FORM AN UPPER COMPARTMENT IN COMMUNICATION WITH THE STEAM CHEST AND A LOWER COMPARTMENT IN COMMUNICATION WITH THE CONDENSATION COLLECTING MEANS, THE TWO COMPARTMENTS BEING CONNECTED BY A PASSAGE IN THE END PORTION OF THE HEATING PLATE REMOTE FROM THE END WALL OF THE VESSEL, SO THAT STEAM FLOWING THROUGH THE UPPER COMPARTMENT MAY ASSIST IN MOVING CONDENSATION IN THE LOWER COMPARTMENT TO THE COLLECTING MEANS. A CONDENSATION COLLECTING TROUGH IS PROVIDED IN THE LOWER COMPARTMENT, IN UPWARDLY SPACED RELATION FROM THE BOTTOM OF THE LATTER.
