The invention relates to a device (1) for generating steam. The device (1) comprises a water outlet arrangement (2) having an open end (3) to spray water onto a water receiving arrangement (4). The water receiving arrangement (4) comprises an interior surface (5) defining a chamber (6) in which the open end (3) is arranged so that water sprayed from the open end (3) is sprayed onto the interior surface (5). The device further comprises a heating element (7) for heating the interior surface (5) up to a temperature for generating steam from water sprayed on the interior surface (5). The interior surface (5) is formed by two separate cavities (14a, 14b), the open end (3) comprising a spray nozzle (2) received within each cavity (14a, 14b) so that each spray nozzle (2) sprays water onto a region of the interior surface (5), each region being defined by the cavity (14a,14b) in which a respective spray nozzle (2) is received. This allows the water sprayed by the water outlet arrangement (4) be more uniformly spread on the interior surface (5), leading to more effective heating and more steam may be generated per unit time.

Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.
