Abstract:
A single shell boiler comprising:a closed vessel for containing a liquid heat transfer medium, the liquid heat transfer medium having a surface;a first bundle of heat source tubes located in the closed vessel which is adapted to be submerged within the liquid heat transfer medium for heating and vaporizing the liquid heat transfer medium;a second bundle of tubes located in the closed vessel in a position which is adapted to be above the surface of the liquid heat transfer medium within the vessel to receive heat by condensation of vaporized heat transfer medium on the second bundle of tubes;a condensate distribution plate positioned between the first and second bundles of tubes, said condensation distribution plate having a plurality of apertures therethrough, the apertures being arranged to approximately evenly distribute condensate droplets released by the second bundle of tubes to break-up froth on the surface of the liquid heat transfer medium to enhance vapor release from the medium; anda stripper located adjacent to each aperture to prevent bridging of condensate droplets across each said aperture.
