Apparatus for drying and superheating steam

Claim 1

In an apparatus for drying and superheating steam, moistureseparating means of substantially slab form for separating moisture from steam flowing through the moisture-separating means, said moisture-separating means having a discharge face of relatively large area through which the steam flows perpendicularly with respect to said discharge face beyond said moisture-separating means after the steam has been dried thereby, and heat-exchanger means of substantially slab form coextensive with superposed to a fixed to said discharge face of said moisture-separating means for receiving the dried steam therefrom to provide a series-connection with said moisture-separating means and for providing for the dried steam a laminar flow beyond said moisture-separating means perpendicular with respect to said discharge face thereof so that the direction of flow of the dried steam does not change from said moisture-separating means to and through said heat-exchanger means, said heat-exchanger means acting on the dried steam to superheat the latter, and said heatexchanger means having a receiving face of substantially the same area as said discharge face of said moisture-separating means fixed to said discharge face for receiving the dried steam therefrom, said receiving face of said heat-exchanger means and said discharge face of said moisture-separating means being joined to each other at a common plane which is the interface of said slabs and said heat-exchanger means being formed with passages therethrough parallel to said faces and side edges of said heat exchanger slab for receiving a medium from which heat is extracted to heat the dried steam, and said heat-exchanger means being formed with narrow slit passages extending from the receiving face to the discharge face of same for the dried steam to provide laminar flow therethrough and situated between while extending perpendicularly to said passages for the medium from which heat is extracted.
