Definitions

  • Patent Nov. 11, 1975 BACKGROUND OF THE INVENTION There are many uses for boilers which can be put into operation in a relatively short time. An example is found in electric power plants where loads varry in the course ofa day due to a wide variation in the power requirements of consumers during the daily cycle. It is often desirable to have a boiler to provide power for all but the peak loads because such a boiler can be fairly large and run at high efficiency if the energy it must produce is not made to vary over a wide range. The peak loads can be met by using an auxiliary boiler to furnish additional power.
  • the furnace section and convection sections of a steam generator are placed within a pressure vessel and the exhaust gases from the steam generator are used to drive a turbine which in turn drives a compressor which forces hot air downward in the space between the furnace and convection sections and the pressure vessel to burners at the bottom of the steam generator, the air being mixed with fuel at the burners to serve as combustion air, the compressor being operable by means other than the turbine during start-up to pressurize and thus heat the air so that on its way to the burners the air will preheat the steam generator and thereby prevent the creation of large temperature gradients during start-up.
  • the drawing is a front view, partly in section, showing a steam generator made in accordance with the present invention.
  • the drawing shows a steam generator indicated generally as having a pressure vessel 12 which includes a generally cylindrical portion 14 and a top closure 16 which at its periphery is integral with the cylindrical portion 14 and a bottom closure 18 which at its periphery joins the bottom of the cylindrical portion 14.
  • Feedwater enters through a line 20 where it flows into a header 22 to flow into an economizer platen 24.
  • the evaporator tubes 36 are vertical and are either joined to each other or are joined by fins so that the evaporator tubes 36 define an hermetic cylindric furnance section 38.
  • the evaporator tubes 36 extend upward to a level 40 where they extend inward and upward for a short distance.
  • Connecting tubes 42 join to evaporator tubes 36 adjacent the ends thereof and lead to a header 44 which communicates through pipes 46 with a header 48.
  • the header 44 is circular in plan,.
  • header 48 is square in plan and therefore it is necessary to have two headers and to join them by the pipes 46.
  • the header 48 connects with a top header 50 through tubes 52 which pass from the header 48 directly upward to the header 50 which is placed within the pressure vessel 12 adjacent to the top of the cylindrical portion 14 thereof.
  • the tubes 52 are joined together or to fins so that they define a convection section 53 sur rounded by an insulation Wall 54 which is cylindrical generally but which has several portions of increased wall thickness as can be seen from the drawing.
  • the top header 50 is connected by a pipe 56 with a header 58 which is connected to a platen 60 which at its upper portion, exhausts into a header 62 which is connected through a pipe 64 to a header 66 which feeds into a platen 68.
  • the platen 68 extends upward to a header 70 which connects through a downward line 72 which passes through an annular space 74 between the insulation wall 54 and the pressure vessel 12 to a header 76.
  • the header 76 feeds a platen 78 which extends up to a header 80 which is just above the header 76 and which is connected to a steam line 82.
  • the platen 78 constitutes a superheater which is screened from the hot gases by the economizer platen 24. Since the economizer platen 24 is cooled by water which is at a much lower temperature than is the superheated steam within the superheater platen 78, the economizer platen 24 is much better able to withstand the hot gases than is the platen 78.
  • the feedwater which enters the line 20 flows through the header 22 to the platen 24 where it is heated within that platen.
  • the water flows from the header 26 through the pipe 28 and into the header 32 to the evaporator tubes 36 which envelop the furnace 38. While passing upward through the tubes 38, the water is heated with some of it becoming steam.
  • the water and/or steam passes up to the header 50 through the line 52 where it is further heated. Thereafter the water and/or steam flows down through the line 56 to the header 58 and then successisvely through the platen 60 and the headers 62 and 66 to the platen 68 where the steam is collected in the header 70 and then fed through the line 72 to the header 76. Thereafter the steam is led through the platen 78 where it is superheated to be collected at the platen 80 and then flowed out through the steam pipe 82.
  • Fuel is introduced through a fuel line which is connected through lines 92 and 94 to burners 96 and 98 respectively.
  • the fuel is burned within the furnace 38 so that the combustion gases pass upwardly over the platens 24, 78, 60 and 68.
  • the gases are collected under the top closure 16 and passed through an exhaust duct 100 to a turbine 102 which drives a compressor 104.
  • Exhaust gases are vented through a stack 106.
  • the turbine 104 compresses air from the atmosphere and forces it through the duct 108 to the annual air space 74 between the insulation wall 54 and the cylindrical portion 14 of the pressurized vessel 12. Thereafter the air passes down through an annular space 110 between the evaporator tubes 36 and the cylindrical portion 14, to the space 111 immediately above the bottom closure 18.
  • a burner wall 112 in which are mounted the burners 96 and 98 and which at its periphery is joined with the evaporator tubes 36 adjacent the lower ends thereof.
  • the air below the burner wall 112 passes through the burners 96 and 98 to mix with the fuel therein and provide combustion air.
  • the compressor 104 is driven by a motor 112 through a shaft 114 to compress air and feed it through the air duct 108 into the air space 74 and through the air space 110 to the burners 96 and 98. Passing the compressed air raises the temperature of the structure within the pressure vessel 12 so that within a very short time the burners 96 and 98 can be fired and the boiler started up without the creation of any large temperature gradients.
  • a supercharged steam generator comprising:
  • a generally cylindrical pressure vessel having a top closure and a bottom closure
  • a plurality of vertically extending evaporator tubes defining the wall of a furnace section within and at the lower portion of said pressure vessel for flowing water to be heated to steam;
  • said first, and second air spaces being sealed from said furnace section and said convection section;
  • a supercharger comprising:
