The invention refers to a method for generating steam (V) that provides, in particular, to direct a solar radiation or another radiation (R) onto a planar structure (100), and specifically onto a support (2) of said planar structure (100) comprising a material (4) absorbent of said radiation (R), so that the thermal energy released by said radiation (R) causes the evaporation of a fluid (F) that flows as a thin film into a thin cavity (3) of said planar structure (100), with consequent production of steam (V); the invention also refers to the relevant system for generating steam (V) that uses said method and that comprises at least one planar structure (100) comprising, in turn, an upper element (1), a support (2) comprising a material (4) absorbent of solar radiation or another radiation (R), a thin cavity (3) between said upper element (1) and said support (2) inside which a fluid (F) flows as a thin film, onto said planar structure (100) being directed said radiation (R) reflected by at least one reflective device (16) facing said planar structure (100), said system further comprising at least a duct (13) through which is discharged the steam (V) produced by the evaporation of said fluid (F) due to the thermal energy released by said radiation (R). The method and the system according to the present invention are preferably and advantageously employed for generating steam and its subsequent condensation in purification and/ or desalination plants for sea, river, swamp or rain water; the present invention is particularly suitable for use in remote regions and for so-called "off-grid" applications. |
