Definitions

  • the present invention in its most general aspect, refers to a heat recovery steam generator (which is also indicated with the acronym RSG - Recovery Steam Generator or HRSG - Heat Recovery Steam Generator or HRB - Heat Recovery Boiler) comprising a heat exchange unit in fluid communication with at least one water-steam separation chamber and is particularly but not exclusively intended for use in thermoelectric plants of the so-called gas/steam combined cycle type.
  • a heat recovery steam generator which is also indicated with the acronym RSG - Recovery Steam Generator or HRSG - Heat Recovery Steam Generator or HRB - Heat Recovery Boiler
  • thermoelectric plants i.e. plants in which two technological cycles are provided, one carried out by air and fuel (gas or Joule cycle) and the other carried out by water and steam (steam or Rankine cycle), both intended to produce electrical energy with high yield (typically greater than 55%) and/or electrical energy and thermal energy that may be intended for users such as, for example, teleheating networks, desalination plants, and steam distribution networks for industrial processes.
  • the gas cycle of a combined cycle thermoelectric plant of the type considered essentially comprises a compressor, a combustion chamber, a gas turbine and an alternator.
  • the compressor takes in air from the atmosphere taking it to a predetermined high pressure; the air thus compressed is injected into the combustion chamber together with a fuel, generally consisting of natural gas; the mixture that forms is ignited and the high pressure and high temperature gases produced are made to expand in the gas turbine that moves the alternator, which generates electrical energy.
  • the steam cycle of the aforementioned thermoelectric plant comprises a steam generator, a steam turbine and a further alternator.
  • the heat exchange unit of said steam generator generally comprising heat exchangers of the type with water tubes, is placed in a heat exchange relationship with the hot gases discharged by the gas turbine of the aforementioned gas cycle, with a consequent great and quick heating of the water and generation of steam.
  • the steam thus produced is sent to the steam turbine that makes the respective alternator operate to generate electrical energy.
  • a steam generator used in the aforementioned way is called heat recovery steam generator precisely because to generate steam the heat of the hot gases (at about 600°C) discharged by the gas turbine is "exploited".
  • the steam is preferably produced at different pressure levels in order to be able to optimize the energy recovery.
  • the most widely used plant configuration for high-power embodiments provides three pressure levels (high, medium and low) plus a re-superheating of the medium pressure steam returning from the steam turbine, i.e. of the so-called cold re-superheated steam.
  • the tube bundles that take care of the three different operations are structurally independent.
  • the recovery steam generator In the presence of several pressure levels, the recovery steam generator has several evaporation steps (two or three), at different pressures and as a consequence at different saturation temperatures.
  • a hot portion may always be defined, with high metal temperatures and high temperatures of the water/steam mixture enclosed there, and a relatively cool portion, with lower metal temperatures and lower temperatures of the water/steam mixture enclosed there, with respect to those of said hot portion.
  • metal temperatures is intended to indicate the mean temperature of the metal with which the components of the heat exchange unit itself are realized, in particular the mean temperature of the tubes through which the water/steam mixture passes.
  • the recovery steam generator described above has recognized drawbacks, including that of requiring relatively long time periods to be brought to normal pressure and temperature operative conditions. Such a drawback is particularly serious considering the present need to have available a great flexibility of operation of the thermoelectric plant.
  • the technical problem underlying the present invention is that of devising and providing a recovery steam generator of the type considered, capable of overcoming, in a simple and economic manner, the limitations and/or the drawbacks mentioned with reference to the known art; in particular reducing the time of restarting of the steam generator following a shutdown, i.e. the possibility to frequently carry out shutdowns and start-ups of the considered plant, with re-starting times as reduced as possible while respecting the admissible thermal gradients for the components of greater thickness.
  • a heat recovery steam generator comprising a heat exchange unit in which, in normal operative conditions, is defined a hot portion, with high metal temperatures and high temperatures of the water/steam mixture enclosed there, and a relatively cool portion, with lower metal temperatures and lower temperatures of the water/steam mixture enclosed there, with respect to those of said hot portion, and characterized in that substantially shutter-shaped means are interposed between said hot portion and said relatively cool portion in order to thermally insulate said hot portion from said relatively cool portion, said substantially shutter-shaped means being at least partially removable in order to put said hot portion and said relatively cool portion again in fluid communication with each other.
  • a heat recovery steam generator is shown in accordance with the present invention and globally indicated with 10.
  • the recovery steam generator 10 comprises a heat exchange unit 12, comprising a plurality of tube bundles in which, in normal operating conditions, is defined a hot portion, with high metal temperatures and high temperatures of the water/steam mixture enclosed there, and a relatively cool portion, with lower metal temperatures and lower temperatures of the water/steam mixture enclosed there, with respect to those of said hot portion.
  • the heat exchange unit 12 is in fluid communication with one (or more) water-steam separation chambers 14, in jargon also called cylindrical bodies (in figure 1 three cylindrical bodies are shown, operating at different pressures).
  • the heat exchange unit 12 is supported in a smoke flue 13, for example substantially parallelepiped, with a face or section 13a in fluid communication with the exhaust gases of a gas turbine and with an opposite face or section 13b in fluid communication with a chimney stack 13c.
  • the cylindrical bodies 14 are placed above said smoke flue 13.
  • the heat exchange unit 12 of figure 1 comprises a high pressure section 16, which realizes said hot portion, and sections at medium pressure 18 and at low pressure 20, which realize said relatively cool portion.
  • Exemplifying pressure values are 130 bar for the high pressure section, 30 bar for the medium pressure section, and 5 bar for that at low pressure.
  • the hot portion at high temperature, comprises a high pressure evaporator and several bundles of superheating/resuperheating tubes, and possibly a high pressure economizer.
  • the relatively cool portion at relatively low temperature, comprises the medium and low pressure levels, the preheater and possibly a part of the high pressure economizer.
  • substantially shutter-shaped means 32 are interposed between said hot portion and said relatively cool portion in order to thermally insulate said hot portion from said relatively cool portion.
  • Said substantially shutter-shaped means 32 are at least partially removable in order to put said hot portion and said relatively cool portion again in fluid communication with each other.
  • such means 32 comprise a rolling shutter 34, having width substantially equal to the width of the smoke flue 13.
  • the corresponding winding roller 36 of the rolling shutter 34 is arranged at the upper face, or side, or top 13e of the smoke flue 13.
  • the shutter 34 may descend, in substantially vertical manner, until at the lower face, or side, or base 13d of the substantially parallelepiped smoke flue 13, thus insulating the two said portions of said heat exchange unit 12 from each other.
  • FIG. 2 shows a second embodiment of a steam generator 110 according to the invention, in which the components analogous to those of the steam generator 10 are indicated with the same reference number.
  • substantially shutter-shaped means 132 are interposed between said hot portion and said relatively cool portion in order to thermally insulate said hot portion from said relatively cool portion.
  • Said substantially shutter-shaped means 132 are at least partially removable in order to put said hot portion and said relatively cool portion again in fluid communication with each other.
  • Such means 132 comprise a rolling shutter 134, having width substantially equal to the width of the smoke flue 13.
  • the corresponding winding roller 136 of the rolling shutter 134 is arranged at the lower face, or side, or base 13d of the substantially parallelepiped smoke flue 13.
  • the shutter 134 may rise, by means of an actuator 138 provided with cables 140, in substantially vertical manner, until at the upper face 13e of the substantially parallelepiped smoke flue 13, thus insulating said two portions of said heat exchange unit 12.
  • FIG. 3 shows a third embodiment of a steam generator 210 according to the invention, in which the components analogous to those of the steam generator 110 are indicated with the same reference number.
  • substantially shutter-shaped means 232 are interposed between said hot portion and said relatively cool portion in order to thermally insulate said hot portion from said relatively cool portion.
  • Said substantially shutter-shaped means 232 are at least partially removable in order to put said hot portion and said relatively cool portion again in fluid communication with each other.
  • Such means 232 comprise a folding shutter 234, having width substantially equal to the width of the smoke flue 13.
  • a lower end 236 of the folding shutter 234 is constrained to the lower face 13d of the substantially parallelepiped smoke flue 13.
  • the shutter 234 may rise, by means of an actuator 238 provided with cables 240, in substantially vertical manner, until at the upper face 13e of the substantially parallelepiped smoke flue 13, thus insulating said two portions of said heat exchange unit 12.
  • the shutters 34, 134 and 234, which may be automatically or manually operated, insulate said two portions of the heat exchange unit 12 preferably immediately after having begun the generator shutdown procedure, and after stopping the gas flow coming from the turbine.
  • the shutters must be in completely open position during the normal operation of the generators, so to not generate pressure drops and consequently energy dissipations.
  • the location of the shutter is preferably comprised between the high pressure evaporator inlet and medium pressure evaporator outlet for the generators illustrated in the figures (three-pressure level generators) or the low pressure evaporator inlet for two-pressure level generators (not illustrated).
  • the shutter may be situated in a position between the downstream of the high pressure evaporator and the downstream of the third pressure level evaporator.
  • the installation with more than one shutter may be provided.
  • the shutter may be situated downstream of the evaporator.
  • the shutter may be realized with metallic materials (stainless steel) or textile materials. Preferably the shutter is covered with thermally insulating materials.
  • metallic materials stainless steel
  • textile materials Preferably the shutter is covered with thermally insulating materials.
  • the substantially shutter-shaped means may comprise devices of bulkhead type.
  • the levers and/or motorizations for the actuators may be of different types and are arranged inside or outside of the smoke flue. In specifically contingent cases, there may also be provided a manual type actuation.
  • Another advantage of the steam generator according to the invention is that, during the shutdown, the flow of cool air inside the generator is limited, which, in the absence of the shutter, would occur due to the draft of the chimney stack, leading to an additional cooling of the generator during the shutdown.
