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 invention has for its object to make the system much simpler and more economical by performing the function of the low pressure drum through the feed water tank 7.
  • the arrangement according to claim 3 makes it possible to simplify the water-steam system from the waste heat boiler without impairing the function of the system in any way.
  • 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 steam drum, preferably 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 via a line 37 provided with a shut-off device 36 to the feed water tank or steam drum, preferably low pressure drum 12 and / or another system.
  • 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 the line 22 to the low-pressure economizer 1, from which the condensate passes via the degasser 27 into the steam drum, preferably 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 is fed via the riser pipe 42 into the feed water container or the steam drum, preferably the low-pressure drum.
  • the feed water from the feed water container or the steam drum, preferably low-pressure drum 12 via the downpipe 28, the high-pressure feed water pump 13, the line 30, or the inlet manifold or the inlet header is fed to the high-pressure economizer 2.
  • the high-pressure economizer 2 steam reaches the high-pressure evaporator 4 via the line 31 and at least one inlet header (not shown), from which the steam passes through at least one outlet header 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 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 circulating pump 11 and the high-pressure drum 9 unnecessary compared to the known systems.
