Solar-thermal continuous steam generator for use in solar tower-power plant utilized to generate electricity, has steam generator pipe whose flow cross-section and passage area are varied in flow direction of medium to be evaporated

摘要

The generator (8) has a steam generator pipe (23) whose flow cross-section and passage area are varied in flow direction of medium to be evaporated. The flow cross section of the steam generator pipe in the flow direction of the medium is increased based on reduction of wall thickness of the steam generator pipe. The steam generator pipe is aerodynamically connected with an inlet header (24) and an outlet header (25) at an input side. A heating gas channel (20) is provided for heated air that flows in heating gas direction (19).
