Definitions

  • a heat exchanger of a standing type with a tube bundle held in two tube plates is known (AT-A-361 953), in which the upper tube plate arranged on the gas outlet side also has
  • the tube plate 6 is provided in the longitudinal direction of the heat exchanger with tube bores 8 through which tubes 9 are passed. There is an annular gap 10 between each tube 9 and the associated tube bore 8. The inlet ends of the tubes 9 are tightly welded into the tube plate 6 on the side against which the gas flows from the gas supply chamber 4.
  • each tube 9 is bent into a tube spiral, the end of which is connected to a connecting piece 11 which is guided through the jacket 1 just above the tube plate 6.
  • the gas from the gas supply chamber 4 flows through the tubes 9 and is thereby cooled by a cooling medium which is fed in the manner described later through a plurality of supply lines 12 into the interior 13 of the heat exchanger enclosed by the jacket 1.
  • Pressurized water serves as the cooling medium, which evaporates through the heat exchange with the hot gas and leaves the heat exchanger as steam via an outlet connection 14 in the dome 3.
  • the water fed through the supply lines 12 enters the cooling channels 15, flows through them, partly rises through the annular gaps 10 and enters the interior 13 of the heat exchanger.
  • the remaining part of the cooling medium flows through the open ends of the cooling channels 15 directly into the interior 13.
  • Solid particles that are still contained in the cooling medium despite careful preparation are flushed out of the cooling channels 15 with the cooling medium stream and settle in the lowest point of the heat exchanger from.
  • This lowest point lies below the tube plate 6 in the annular space between the cone 7 and the jacket 1.
  • This annular space is unheated since the cone 7 is provided with the refractory lining 5 on the gas side.
  • a suction line 17 opens into the annular space, via which the deposited solid particles can be removed from the heat exchanger.
