Definitions

  • the present invention refers to improve ments in connection with rotating steam boilers of the type comprising a central container communicating with a plurality of tubes mounted around the former in a squirrel-cage like formation, and wherein separate tubes are provided for admission of feed water to the steam generating tubes and for delivery of the generated steam therefrom.
  • the w, central container may also contribute to the steam generation, and may serve as a receiver for the steam generated within the tubes.
  • the invention has for its main object to eliminate the difliculty referred to in the foregoing by establishing a continuous flow of the feed water in the same direction throughout This is 'per' the entire length of. the tubes.
  • the efiiciency of the invention may be further increased by the arrangement of scraper chains within the steam generating tubes such chains effectively preventing the sludge from adhering to the interior walls of the tubes.
  • Another means adapted for still further improvement of the result is the provision of an injector for increasing the rapidity of water flow through the steam generating tubes, this injector acting under influence from the fresh feed water forcibly fed in and serving to convey an additional amount of water from the central container in circulation though the steam generating tubes together with the fresh feed water.
  • the Water is displaced from the left to the right in the drawing by means of the tubes 3, a part of the same being converted into the form of steam when passing the tubes 3, the remainder flowing further through the-return pipes 5 into the central container 4.
  • the tubes 3 are interiorly provided with scraper chains 3 which at the rotation will continually perform a scraping action against the inner face of the generating tubes so as to prevent any deposit of impurities on the tube walls, the impurities contained in the water being then conveyed by the flow of the same into the central container.
  • such container is also provided with a scraper chain e.
  • the generated steam is delivered through a fixedly mounted pipe 6 provided with an upwardly bent inner end positioned at a level above the surface of the bulk of water within the container 4.
  • a draining pipe 7 having a clown-bent inner end is also provided within the container 4 such pipe extending into the bottom portion of the container, and by means of the same a certain amount of water may be continually or periodically blown oif from the container, then conveying the impurities accelerate the flow of water through the generator, and especially through its' generating tubes.
  • an injector which consists of a tube 8 mounted coaxially around the steam delivery tube 6 and acts for the sucking in of additional feed water to the generating tubes 3 from the central container 4, such additional feed water forming a circulation feed water flow.
  • This injector means may for instance consist of a reduced or throttled portion 9 of the tubular feed water inlet pivot 1, in which the outlet end of the pipe 8 is mounted.
  • the feed pipes 2 must therefore be shaped in a manner permitting an easy deformation.
  • this may be arrived at by constructing the feed pipes 2 in the form of coils permitting the variation in length of the steam generating tubes 3., forinstance as shown'in the drawing.
  • the steam boiler body according to the invention may be mounted so as to rotate around a horizontal axis, or even the axis of rotation may take an inclining position.
  • a central container In a rotating steam boiler of the character described, a central container, a plurality of steam generating tubes positioned in a squirrel-cage like formation around the 3.
  • a central container In arotating steam boiler of the char acter described, a central container, a plurality of steam generating tubes positioned in a squirrel-cage like formation around the same, means for the force-feed admission of fresh feed water at one end of the said steam generating tubes, means for returning of additional feed water from the central container to the generating tubes at the same end of the latter, means for connecting the opposite ends of the said tubes with the cen-;
  • squirrel-cage like formation around the same means for the force-feed admission of fresh feed water at one end of the said steam generating tubes independently of the central container, injector means actuated by the fresh feed water forcibly fed in and adapted for returning of additional feed water fro-m the central container to the generating tubes at the same end of the latter, means for connecting the opposite ends of the said tubes with the central container, and means for delivery of the generated steam from said container.

  • a rotating steam boiler of the character described a central container, a plurality of steam generating tubes positioned in a squirrel-cage like formation around the same, an inlet adapted for the force-feed admission of fresh feed water to the tubes, aflexible pipe connection connecting each of the steam generating tubes at one end of the boiler with said feed water inlet independently of the central container, rigid tubular return pipe connections between the generating tubes and the central container at the opposite end of the boiler, such return pipes being adapted to form over-fiow means Within the steam generating tubes, injector means actuated by the fresh feed Water forcibly fed and in the central container, and means for blowing off the sludge from the bottom portion of the latter.
