The present invention relates to a saltwater
evaporator (1) comprising a housing (10), which substantially encloses an inner space (11) having at least one steam outlet opening (12) and has at least a first saltwater feed (11a), wherein the surface of the inner space (11) and the first saltwater feed (11a) are designed to allow saltwater (A), as a saltwater film (B), to run off along the
vertical axis (Z) on the surface of the inner space (11), and comprising at least one heat source (16, 17), which is designed and arranged within the inner space (11) in order to contactlessly heat the side of the saltwater film (B) which faces away from the surface of the inner space (11) and faces the heat source (16, 17) in such a way that exactly one part of the
liquid phase of the saltwater film (B) is evaporated, wherein the housing (10) further comprises at least one saltwater outlet (11c) of the inner space (11), which is arranged and formed along the
vertical axis (Z) below the first saltwater feed (11a) to carry off the rest of the
liquid phase of the saltwater film (B) out of the inner space (11).
