A method and a device for the production of pure steam, wherein steam produced in downflow evaporation tubes is carried upwards in a spiraling path. In the outer wall of the spiral path, openings are provided for capturing droplets carried to the wall by centrifugal force. A radial flow through the openings is generated as steam condenses on a cooled surface outside the openings. Impurities are enriched in the water phase that forms on the cooled surface, and the water phase flows downwards by gravity to form a pool of reject water, a flow of which is constantly removed from the process. Pure steam is withdrawn from above the spiral path.
