Definitions

  • the present invention relates to an integrated air-separating and water-heating apparatus intended for a boiler.
  • U.S. Pat. No. 4,461,154 discloses the use of an adiabatic compressor for compressing air and recovering the heat generated at the outlet of the compressor to heat the water which is supplied to a boiler, with the aim of improving the overall efficiency of the air-separating device fed by the compressed air and also of the boiler (for the purpose of reducing the fuel consumption of the boiler).
  • WO-A-2006/131283 describes a device in which the air from a compressor is heated by flue gases and is then used to heat the water in two separate exchangers.
  • DE-C-19837251 describes an air-separating device integrated with a gas turbine.
  • the steam is extracted from a turbine and is then used to preheat the water intended for a boiler.
  • the present invention enables the heat recovery from an air compressor to be optimized by preheating the boiler feed water.
  • the water supplied to a boiler is sent to a degasser to separate the oxygen dissolved in it, typically in order to reduce the oxygen content to less than 10 ppb by direct steam stripping of the water.
  • this degassing must take place at a pressure of less than 20 bar, and preferably less than 10 bar.
  • the air When a compressor is used to compress all the air intended for a cryogenic air-separating device, the air must typically be produced at 6 bar abs and therefore at a temperature of 230° C. to 300° C. for an adiabatic compressor.
  • the boiler feed water could be heated to between 220° C. and 295° C. (allowing for the fact that a temperature difference of less than 5° C. would entail significant additional costs).
  • the relation between the flow of water intended for the boiler (and obtained from the turbine condenser) and the flow of air is 380 kg of water per 1000 Nm 3 /h of air.
  • the air leaves the compressor at 273° C.
  • the water leaves the condenser at 45° C.
  • the minimum temperature difference in the exchanger where the water is heated by the air is 10° C.
  • the water can only be heated to 224° C., whereas a temperature of at least 250° C. would be desirable.
  • another heat source is used to complement the heat received from the air compressor, in order to raise the temperature of the water intended for the boiler.
  • the invention proposes an integrated apparatus, including an air compressor, a steam turbine which drives the air compressor, a first heat exchanger, means for feeding water to the first heat exchanger and from there to a boiler, means for feeding compressed air from the compressor to the first heat exchanger and an air-separating device supplied with air compressed in the compressor, heating means for heating the water downstream from the first exchanger, a second exchanger, means for feeding water from the first exchanger to the heating means, from the heating means to the second exchanger, and from the second exchanger to the boiler, and means for feeding air from the compressor to the second exchanger upstream from the first exchanger, without preheating means between the compressor and the second exchanger, and from the second exchanger to the first exchanger.
  • the air from the compressor heats the water without having been preheated by flue gases as in the prior art.
  • the invention also proposes a method of heating water intended for a boiler in which water is heated in a first heat exchanger by an exchange of heat with air from a compressor driven by a steam turbine, after which the air cooled in this first exchanger is fed to an air-separating device, characterized in that the water from the first exchanger is reheated and fed to a second exchanger, preferably without having been reheated, where it exchanges heat with air from the compressor, the air from the compressor not being preheated between the compressor and the second exchanger, the air cooled in the second exchanger is fed to the first exchanger, and the water heated in the second exchanger is fed to the boiler.
  • the air compressor produces air at a first pressure and the air is fed to the air-separating device at this first pressure, without compression downstream from the air compressor.
  • all the air from the compressor is fed to the air-separating device.
  • FIGS. 1 and 4 show apparatus according to the invention and FIGS. 2 and 3 are Q-T diagrams of an exchanger of the apparatus.
  • water 27 is extracted from a condenser 23 at 45° C. and is pumped to 15 bar by a pump 25 .
  • This pumped water is heated by indirect exchange in a first exchanger 29 to a first temperature of at least 100° C., preferably at least 130° C., possibly at least 150° C., or even at least 170° C., for example 175° C. in this case.
  • the water recovers heat from the air 35 from an air compressor 31 .
  • the compressor can be adiabatic or can have cooling means between the stages.
  • the hot water is fed to a degasser 3 which receives water vapor 5 at 14 bar from a boiler 1 . The water is thus heated from its first temperature to 196° C.
  • the water 7 at 196° C. is pumped by the pump 9 to 150 bar, creating the flow 11 , and is fed to a second exchanger 13 where it exchanges heat with air 33 from the air compressor 31 . After passing through the two exchangers, the air 37 is fed to an air-separating device which is illustrated in FIG. 4 .
  • the flow of water at high pressure 15 is fed to the boiler 1 .
  • the water vapor 19 from the boiler 1 is fed to a steam turbine 17 which drives the air compressor 31 .
  • the steam 21 is then fed to the condenser 23 .
  • the air is not compressed between the outlet of the compressor 31 and the inlet of the air-separating device 49 .
  • FIG. 2 illustrates the heat exchange in the two exchangers 13 and 29 . This configuration permits good utilization of the heat from the compressor and efficient degassing at medium pressure.
  • FIG. 4 is an illustration of a version of FIG. 1 , showing the air-separating device in greater detail.
  • the air 37 from the compressor 31 is fed to a purification device 41 , and from there to a cryogenic distillation air-separating device 49 .
  • a liquid product from the separating device 49 is vaporized in an auxiliary vaporizer 51 .
  • the purification device is regenerated by a flow of nitrogen 43 from the air-separating device 49 .
  • This nitrogen flow can be preheated by water vapor from the boiler 1 and/or by water vapor 55 from the degasser 3 and/or from the boiler blow-offs.
  • the water vapor from the boiler 1 is a fraction of the flow 5 to be sent to the degasser 3 .
  • a part 57 of the water heated to approximately 150° C. in the first exchanger 29 can be used to heat the regeneration nitrogen 43 .
  • This water can be drawn off continuously and stored in a thermally insulated store (not shown) and sent when required to heat the regeneration nitrogen.
  • Water vapor 53 from the degasser 3 can be used to vaporize a cryogenic liquid of the air-separating device in an auxiliary vaporizer 51 .
  • Part of the water vapor 5 and/or of the water 57 and/or of the water vapor 45 and/or of the water vapor 55 can also be used to heat an absorption cooling unit of the air-separating device 49 .
  • the air is not compressed by any compressor means between the air compressor 31 and the air-separating device 49 , and all the air from the air compressor 31 is fed to the air-separating device 49 .
