  • Myinvention relates to vapor generators and specifically-to an arrangement of tubes for vapor generators Consisting of a heated system of tubes.
  • My invention has as its object to provide an arrangement of tubes for vapor generators consisting of a heated system of tubes, in which the mixing of the working medium heated in the individual parallel tubes can take place without interrupting the genera tion of vapor. It consists in alternately dividing the quantity of workinginedium to be evaporated into several parallel currents and re-uniting the individual currents into asingle main current,the partial currents and the re-united current flowing, each in their respective section, about the same distance. The mixing of the partial currents, into which the quantity of working medium was divided, then takes place in the tube, in which the quantity of working medium is reunited to a singlecurrent. In order to avoid an interruption in the generation of steam, the tube in which tne quantity of working medium is re-united to a single current, may also be exposed to'the influence of the heat-V mg gases. According to the invention, the invention, the

  • each layer consists of a plurality'in thiscase twoof banks of parallel tubes 3 and '8, the tubes?) being joined at one end by acommon distributor 2 and at the other end by a common collector 4.
  • the bank of tubes 8 is j oined at one end by distributor 7 and at theother end by collector-f9.
  • each bank has two superp'osed-rowsgof tubes.
  • the banks within each layer are arranged side by side in the plane of the layer, and have all distributors atone end of the layer and all collectors at the other end.
  • the collector, such a's 4, of one bank is connected with the distributor, such as 7, of the next adjacent bank by a mixing tube'5,*of sufficient size to carry the operating medium flowing through all tubes of its pertaining bank, suchias 3, this mixing tube running in parallel to the tubes andbeing exposed, the same as the tubes, to the heat of the combustion gases.
