Definitions

  • the invention relates to a waste heat steam generator according to the preamble of claim 1.
  • the supercooled condensate can be pumped into the feed water tank 7 by means of a condensate pump 20, possibly via preheaters, not shown, and via a degasser 38, as indicated by dash-dotted lines.
  • the degassed feed water is conveyed on the one hand via a low-pressure feed water pump 10 and preferably an economizer 1 into a low-pressure drum 8 and on the other hand via a high-pressure feed water pump 13 and a high-pressure economizer 3 into a high-pressure drum 9.
  • a low-pressure feed water pump 10 and preferably an economizer 1 into a low-pressure drum 8 and on the other hand via a high-pressure feed water pump 13 and a high-pressure economizer 3 into a high-pressure drum 9.
  • the water is introduced via the low-pressure circulation pump 14 into a low-pressure evaporator 3, from which the low-pressure steam is fed to the low-pressure drum 8 on the dash-dotted path.
  • the steam is fed to the low-pressure part 18 of a steam turbine 39 via the low-pressure superheater 5.
  • the water is fed via the high-pressure circulation pump 11 to the high-pressure evaporator 4, from which the steam arrives in the high-pressure drum 9 by the dash-dotted path. Steam is then introduced from this drum via the dash-dotted path into the high-pressure superheater 6, from which the high-pressure steam reaches the high-pressure part 17 of the steam turbine 39.
  • the degassed water is conveyed through various heating surface systems by means of feed pumps.
  • the steam drum also has the function of a feed water container, from which steam is fed to the low-pressure part via a low-pressure superheater, the steam turbine and water via a high-pressure feed pump and a high-pressure preheater from a high-pressure drum, from which steam via a high-pressure superheater to the high-pressure part of the steam turbine and water via a High pressure circulation pump and a high pressure evaporator is fed to the steam section of the high pressure drum.
  • This system is a two-pressure system with an integrated feed water tank. The low pressure as well as the high pressure system works in forced circulation via a steam drum.
  • the invention has for its object to make the system much easier and more economical.
  • an exhaust gas duct is designated, through which the exhaust gas coming from a gas turbine or several gas turbines flows in the direction of arrow A. and from which, after the heat has been given off, the exhaust gas flows into the open through an exhaust gas chimney 40 in the direction of arrow B.
  • a high-pressure superheater 6, a low-pressure superheater 5, a high-pressure evaporator 4, a low-pressure evaporator 3, a high-pressure economizer 2 and a low-pressure economizer 1 are arranged one above the other in the exhaust gas duct 21 in the direction of the flow of the exhaust gas.
  • the arrangement can also be done in a different way.
  • the low-pressure economizer 1 is on the input side via a collector (not shown) and a line 22 with a condensate pump 20 in connection, which is connected on the input side via a line 23 to a condenser 19 which is connected to a steam turbine 39 which consists of a high-pressure part 17 and a low-pressure part 18.
  • a conduit 25 for supplying water for the water consumed in the system can open into the condenser 19.
  • the low-pressure economizer 1 is connected on the output side via at least one collector (not shown) and a riser pipe 26 to a degasser 27 of any system of a feed water tank or a low-pressure drum 12, which at the same time also has the function of a feed water tank.
  • the water space of the feed water container or steam drum, preferably the low pressure drum 12 is connected on the one hand via a down pipe 28 to a high pressure feed water pump 13 and on the other hand via a down pipe 29 to a low pressure circulation pump 14.
  • the high-pressure feed water pump 13 is connected via a line 30 and an inlet manifold, not shown, to the high-pressure economizer 2, which is connected to the high-pressure evaporator 4 via at least one outlet manifold, not shown, a line 31 and at least one inlet manifold, also not shown.
  • the latter is connected to a water separation system 15 via at least one outlet manifold, not shown, and a line 32, from which, on the one hand, a line 33 leads to the high-pressure superheater 6 via at least one inlet manifold, not shown. and which, on the other hand, is connected to at least one collector, not shown, from which a line 41 leads to a high-pressure part 17 of the steam turbine 39.
  • the low-pressure superheater 3 is connected on the outlet side to the feed water tank or the steam drum, preferably the low-pressure drum 12, via at least one outlet header (not shown) and at least one riser pipe 42.
  • the water separation system 15 is also connected to a relaxation system 16 via a line 35 connected to a shut-off device 34 and connected to the feed water tank or the low-pressure drum 12 and / or another system via a line 37 provided with a shut-off device 36.
  • the waste heat steam generator according to the invention works in the following way:
  • the steam coming from the steam turbine 39 condenses in the condenser 19, from which the condensate pump 20 feeds the condensate via line 22 to the low-pressure economizer 1, from which the condensate passes through the degasser 27 into the low-pressure drum 12, which functions as a feed water tank, in which the Separation of steam and water takes place.
  • the feed water is fed to the low-pressure evaporator 3 by means of a circulating pump 14 and passed via the riser pipe 42 into the feed water container or the low-pressure drum.
  • the feed water from the feed water tank or the low-pressure drum 12 is fed to the high-pressure economizer 2 via the downpipe 28, the high-pressure feed water pump 13, the line 30, and the inlet header (s).
  • steam reaches the high-pressure evaporator 4 via the line 31 and at least one inlet manifold (not shown), from which the steam passes through at least one outlet manifold (not shown) and the water separation system 15, the line 33 and the high-pressure superheater 6 into the high-pressure part 17 of the steam turbine 39 . arrives.
  • the feedwater tank 7 and the low-pressure drum 8 shown in dash-dotted lines are combined to form a common container 12, the other lines shown in dash-dotted lines making the low-pressure feed water pump 10, the high-pressure circulation pump 11 and the high-pressure drum 9 unnecessary compared to the known systems.
