Definitions

  • an enlarged low-pressure steam drum assumes the function of the feed water tank into which the entire feed water is conveyed (so-called full-flow feedwater tank).
  • the low-pressure drum then receives a feedwater degasser, whereby solutions are known in which the degasser is placed on the low-pressure drum (so-called integral degasser).
  • Heat recovery steam generator which is used in the relaxed working fluid of an associated gas turbine heat to generate steam for an associated steam turbine with at least one low pressure part and a high pressure part, wherein the low pressure part in the heat recovery steam generator is associated with a low pressure drum with a low pressure drum, dissolved in water or steam gases of substantially Steam for the low pressure part are degassed from the low pressure drum and the steam production in the low pressure drum for controlling the degassing is changed by that heat is shifted within the heat recovery steam generator by in a middle (42) or high pressure stage (22) of the gas turbine plant ( 1) less heat is removed from the working fluid.
  • the arrangement of the degasifier can also take place in an integrated form, i. the degasser can be fixedly connected to the low pressure drum, e.g. be based on it, but also be constructed as a separate container next to the low-pressure drum.
  • the degasser is dimensioned for a low-pressure steam, so that in contrast to the aforementioned plant, the low-pressure drum does not have to be sized larger than necessary for the low pressure stage.
  • the first and second Kondensatzweigtechnisch are connected to the condensate line via a condensate preheater arranged in the heat recovery steam generator and a Kondensatvormaschiner- Um arrangementstechnisch.
  • a feedwater preheater associated with the high pressure stage is associated with a feedwater preheater bypass line.
  • a feedwater preheater associated with a medium pressure stage is associated with a feedwater preheater bypass line.
  • the steam turbine 3 consists of a high-pressure part 7, a medium-pressure part 8 and a low-pressure part 9.
  • Kondensatzweig admir 13 connected to a low pressure part 9 of the steam turbine 3 associated low pressure stage 14 of the water-steam cycle and on the other hand connected via a second Kondensatzweig effet 15 to a feedwater pump 16.
  • the feedwater pump 16 is connected via a closable with a valve 17 recirculation line 18 with the
  • Condensate line 11 connected.
  • Condensate line 11 connected.
  • the branches off and flows into both the first 13 and the second Kondensatzweigtechnisch 15, a in the
  • Condensate preheater 10 preheated condensate are added.
  • the condensate under high pressure can be fed to the high-pressure stage 22 as feedwater via a high-pressure feedwater preheater 23, which is connected on the output side via a feedwater line 24 to a high-pressure drum 25.
  • the high-pressure drum 25 is connected to a high-pressure evaporator 28 arranged in the heat-recovery steam generator 6 to form a water-steam circulation.
  • the high-pressure drum 25 is connected to a high-pressure superheater 29 arranged in the heat-recovery steam generator 6, which is connected on the output side to the steam inlet 30 of the high-pressure part 7 of the steam turbine 3.
  • the steam outlet 31 of the high-pressure part 7 of the steam turbine 3 is connected via a reheater 32 to the steam inlet 33 of the medium-pressure part 8 of the steam turbine 3. Its steam outlet 34 is connected via an overflow line 35 to the steam inlet 36 of the low-pressure part 9 of the steam turbine 3.
  • the steam outlet 37 of the low pressure part 9 of the steam turbine 3 is connected to the condenser 5, so that a closed water-steam cycle is formed.
  • From the feedwater pump 16 also branches off at a point at which the condensate has reached a mean pressure, a feedwater line 38 from. This is connected to a medium-pressure feedwater preheater 39, which is connected on the output side via a feedwater line 40 to a medium-pressure drum 41 of the medium-pressure stage 42.
  • the medium-pressure extraction of the feedwater pump 16 can also be shut off via a valve 43 which can be shut off
  • the medium-pressure drum 41 is provided with an im
  • Heat recovery steam generator 6 arranged medium-pressure evaporator 45 connected to form a water-steam circulation.
  • the medium-pressure drum 41 is connected to a medium-pressure superheater 46, which in turn is connected on the output side via a steam line 47 to the reheater 32 and thus to the steam inlet 33 of the medium-pressure part 8 of the steam turbine 3.
  • Heat recovery steam generator 6 arranged low-pressure evaporator 49 is connected to form a water-steam circulation.
  • the low-pressure drum 48 For discharging low-pressure live steam, the low-pressure drum 48 via a low-pressure superheater 50 and a
  • a degasser 52 is connected in the feedwater flow to the low-pressure drum 48.
  • the arrangement of the degasser 52 can also be done in an integrated form, ie it can be fixedly connected to the low-pressure drum 48, z. B. on it be attached, but it can also be constructed as a separate container in addition to the low-pressure drum 48.
  • Heat recovery steam generator 6 is moved.
  • either the feedwater preheater bypass line 44 in the intermediate-pressure stage 42 or the feedwater preheater bypass line 27 in the high-pressure stage 22, or also both feedwater preheater bypass lines 44, 27 can be opened.
  • hotter flue gas reaches the condensate preheater 10 and thus allows a stronger heating of the condensate, whereby a larger amount of water or steam can be degassed.
