Definitions

  • the invention relates to a once-through steam generator with a gas flue for Connection to a hot gas dispensing device, in particular Gas turbine, at least with a first evaporator heating surface and one of these upstream on the exhaust gas flow side and downstream on the steam side second evaporator heating surface, the heating surfaces being constructed from pipes are and can be charged via collectors.
  • Such a continuous steam generator is known from EP-0 425 717 B1, at which the evaporator heating surfaces are arranged in a vertical gas flue and no collectors are arranged between the two heating surfaces.
  • evaporator heating surfaces are modular across the width of the throttle cable with one or more parallel water-steam paths are trained.
  • each module from at least a partial evaporator heating surface arranged in a vertical plane first evaporator and at least one in the same vertical plane arranged partial evaporator heating surface of the second evaporator with each assigned collectors exists, and the collectors via an external and in connecting line lying on the same vertical plane are.
  • a module having a depth as shown in the following FIGS. 2 and 4 can be seen.
  • the training of the collectors takes place in that the collectors in the two end sections of the connecting line by chamber formation are built up.
  • Feed water preheater 2 In a horizontally extending flue gas duct 1 with a rectangular one Cross section, floor 1a, ceiling 1b, side walls 1c-1d is initially a Feed water preheater 2 arranged.
  • the feed water S to be heated is fed via an entry collector 3, of which there are a variety of pipes 4 extending vertically through the flue gas duct 1
  • Outlet collector 5 is fed.
  • the outlet collector 5 becomes Feed water via connecting lines 6 to an inlet header 7 fed, from which it is also vertically through a variety of itself Lines 8 extending flue gas flue are fed to an outlet header 9 becomes.
  • the preheated is heated via one or more connecting lines 10 Water fed to an evaporator inlet header 11.
  • evaporator inlet header 11 As from the 1 and 2 can be seen is the Evaporator inlet header 11 with four evaporator modules 12a-12d connected.
  • Each evaporator module 12 consists of a first evaporator section 13 and a second evaporator section 14.
  • first evaporator section 13 and a second evaporator section 14.
  • the entry collector 11 two each through the Flue gas duct 1 connected pipes 16a and 16b connected to the Passage through the flue gas duct connected to a collector chamber 17 are.
  • two pipes 18a, 18b are connected, the Push the flue gas duct through to the other side and there into a U-shaped one Pass over sheets 19a, 19b.
  • At the arches 19a, 19b close the Flue gas channel in turn passing through pipe sections 20a and 20b, the are connected to a collector chamber 21.
  • a further partition wall 28 is welded into the rectilinear section 25e.
  • two each go from the connecting line Pipes 29a, 29b passing through the flue gas duct.
  • the over curved Sections 30a, 30b adjoining rectilinear sections 31a and 31b are connected to a collector chamber 32 which is above the sheet 28 in the connecting line is formed.
  • the Connection line is closed at its free ends 25f and 25g. From Chamber 32 in turn emanates from two tubes 33a, 33b, which become one Evaporator outlet header 34, the outlet header for all four Evaporator modules 12a-12c.
  • the outlet collector 34 is on the output side one or more separation vessels 35 connected.
  • the evaporator module 12 is not on the Two configuration of the pipes passing through the flue gas duct 1 are restricted is. Of course, in a practical embodiment, there are more than two Pipes provided.
  • the first Evaporator section 13 with tubes 16a, 16b, 18a, 18b / 20a, 20b / 22a, 22b / 24a, 24b on the steam side in cocurrent to the incoming exhaust gas AG flows through.
  • the second evaporator section 14 with the pipes Exhaust gas flows through 29a, 29b / 31a, 31b / 33a, 33b in cocurrent.
  • the connecting line 40 then consists of a first straight cylindrical Section 40a, in which the chambers 17 'and 21' are formed, from one Connection section 40b and an adjoining straight cylindrical portion 40c in which the chamber 32 'is formed.
  • FIGS. 1 and 2 are comparable elements from FIGS. 1 and 2 with provided apostrophized reference numerals.
  • the pipe sections 18, 20, 22, 24, 29, 31, 33, which are within the Flue gas flue can extend in a known manner with ribs 39th be provided.
