Abstract
A method and steam generator includes a steam generator container having a heated wall surface, an inlet for a liquid and an outlet for removing the vaporized liquid or steam, a rotor, which is mounted for rotation in the container and causes a rotational flow of the liquid outwardly against the heated wall to cause vaporization. During rotation of the rotor, outer edges of the blades of the rotor contact the wall surface to either abrade or wipe deposits, such as lime, from the wall surface.
Claims33
A method for generating steam comprising the steps of providing a steam generating vessel having an outer wall, a liquid inlet and an outlet, at least a first rotor mounted for rotation in the steam vessel, and a drive for rotating the rotor, heating the wall surface of the steam-generating vessel, adding liquid through the inlet, rotating the rotor to place the liquid in rotation and to press it against the heated wall surface, separating any entrapped drops in the steam before it exits the outlet and removing deposits on the wall surface of the steam-generating vessel by an outer edge of the rotor lightly engaging said wall surface.
An apparatus for generating steam, said apparatus comprising a steam-generating vessel having an inlet for receiving a liquid and an outlet through which steam can escape, a heating device for heating liquid in the steam-generating vessel, at least one first rotor being mounted in the steam-generating vessel, an arrangement for rotating said rotor so that liquid in the steam-generating vessel is placed into rotation and forced against a wall surface of the steam-generating vessel, said first rotor including a stripper device that at least regionally strips deposits from a wall surface of the steam-generating vessel during rotation thereof.
