Definitions

  • the present invention refers to a header device for a heat exchanger system, for instance for a so called boiler for heating of water to be evaporated. More specifically, the present invention refers to a header device for a heat exchanger system comprising a tube arrangement configured to convey a fluid to be heated according to the preamble of claim 1.
  • the present invention also refers to a heat exchanger system comprising a header device.
  • the present invention refers to a method of heating a fluid in a heat exchanger system comprising a channel, a tube arrangement arranged inside the channel and a header having a header inlet and a header outlet connected to the tube arrangement, the method comprising conveying a high temperature fluid through the channel, and supplying a first fluid to the header via the header inlet.
  • US-4,351,277 discloses an economizer of the type having a vertically extending cylindrical casing in which is mounted a plurality of spiral coils arranged in parallel to each other in concentric relation with respect to the central vertical axis of the cylindrical casing.
  • the spiral coils are in the form of finned tubes.
  • a heat exchange fluid is conducted through the spiral coils whereby the coils can extract heat from exhaust gases passing upwardly through the economizer from a boiler.
  • the economizer comprises an inlet header comprising a pipe which receives the fluid to be heated.
  • the pipe has an outer wall and encloses an inner space. Seven outlet openings extend through the wall and are connected to a respective one of the spiral coils.
  • Steam systems with forced circulation may comprise a heat exchanger, for instance a boiler, for heating and evaporating water by means of a heat source, such as flue gases, solar energy, etc.
  • the heated and evaporated water may be conveyed from the heat exchanger to a so called steam drum, in which water is separated from the steam and collected in a lower part of the steam drum.
  • the steam may then be conveyed from the steam drum to a steam consumer, for instance a heat exchanger or steam turbine.
  • heat is recovered from the steam and condensed water may be collected in a so called hot well.
  • a feed water pump the water from the hot well may be conveyed back to the steam drum.
  • the water collected in the steam drum may be conveyed to a water inlet of the heat exchanger via an inlet conduit by means of a circulation pump.
  • the circulation pump may raise the pressure of the water by for instance about 1 bar, thereby forcing the water into the heat exchanger, where the water is again evaporated.
  • Steam systems with natural circulation may differ from the steam systems with forced circulation in that the circulation pump is replaced by a long vertical inlet conduit, a so called down comer.
  • the steam drum should then be arranged at a level well above the water inlet of the heat exchanger. For instance a height of the down comer of approximately 10 m may create a pressure increase of about 1 bar, which may be sufficient to force the water into the heat exchanger and maintain the circulation in the steam system.
  • US-4,072,182 discloses an apparatus for transferring heat energy from a high temperature fluid to a low temperature fluid comprising a liquid-vapor separator and a mixer for liquid-vapor remixing.
  • WO 2015/039158 discloses a device for temporary storage of thermal energy, comprising a housing for accommodating a heat storage medium, particularly a phase change material, with at least one heat transfer medium line which is arranged in the housing and is connected to a feed device for feeding a heat transfer medium in a heat-storage process.
  • the feed device has a double pipeline with an inner pipeline which conveys the heat transfer medium in the vapour state and with an outer pipeline which conveys the heat transfer medium in the liquid state.
  • the inner pipeline has, in the region of a passage opening between the outer pipeline and the heat transfer medium line, an exit opening so that a two-phase flow containing the heat transfer medium in the liquid state and in the vapour state can be fed into the heat transfer medium line.
  • the object of the present invention is to provide an alternative solution to the down comer and the circulation pump. Especially, it is aimed at an alternative solution, which maintain an efficient circulation without the need for a circulation pump and/or a down comer.
  • header device initially defined which is characterized by the features of the characterizing portion of claim 1.
  • the second fluid will operate to force the first fluid into the tube arrangement by means of an ejector action. Consequently, it may be dispensed with a circulation pump for the first fluid. Furthermore, there is no need for a long down comer, which means that the steam drum may be positioned relatively closely to the tube arrangement.
  • the tube arrangement comprises a number of tubes for the fluid to be heated, wherein the header outlet comprises a number of openings through the wall of the outlet portion, and wherein each opening is configured to be connected to a respective one of the tubes.
  • the wall of the outlet portion around the openings may be even, especially without any projecting parts extending into the inner space from the wall of the outlet portion.
  • the number of tubes of the tube arrangement may be one single tube or a plurality of tubes.
  • the number of tubes may be 2, 3, 4, 5, 6, 7, 8 or even more tubes.
  • the number of openings through the wall of the outlet portion may, or may not, be the same as the number of tubes. Thus, one or more of the openings may be connectable to a single one of the tubes and vice versa.
  • a first portion of the injector pipe comprises an injector outlet and extends inside the inner space of the header.
  • the injector pipe with the injector outlet in the inner space may further increase the circulation of the first and second fluids in the tube arrangement.
  • the injector outlet comprises a number of holes through a wall of the injector pipe.
  • the wall of the injector pipe around the holes may be even, especially without any projecting parts extending into the inner space from the wall of the injector pipe.
  • the holes may thus be just holes having no further elements defining the injector outlet.
  • the number of holes may be one single hole or a plurality of holes, for instance the injector outlet may comprise 2, 3, 4, 5, 6, 7, 8 or more holes through the wall of the feed pipe.
  • the holes of the injector outlet may have different areas, or equal areas. By selecting the area and position of each hole, it may be possible to control the flow to each tube of the tube arrangement, and to even out the flow distribution to the different tubes. This may be advantageous since the length, and thus the flow resistance, of the tubes may be different.
  • the number of holes through the wall of the injector pipe may differ from the number of openings through the wall of the outlet portion. Especially, the number of holes through the injector pipe may be less than the number of openings through the wall of the outlet portion.
  • the holes of the injector outlet face the openings of the outlet portion. Center axes of the holes and the openings may, or may not, coincide.
  • the first portion of the injector pipe is arranged separated from the wall of the inner space.
  • the header outlet has a first flow area and the injector outlet has a second flow area, wherein the first flow area is larger than the second flow area.
  • the area of each opening through the wall of the outlet portion may be larger than the area of each hole through the wall of the injector pipe.
  • the larger flow area of the header outlet in comparison with the flow area the injector outlet may permit the flow of the first fluid to be larger than the flow of the second fluid. A small flow of the second fluid may thus be used to circulate a large flow of the first fluid.
  • a longitudinal center axis of the first portion of the injector pipe extends in parallel to a longitudinal center axis of the outlet portion of the header.
  • the two parallel axes may permit holes and the openings to be aligned with each other.
  • the inlet portion extends to a first end of the header and the outlet portion extends to a second end of the header, wherein the second end is closed.
  • the fluid entering the header thus has to pass out through the header outlet, i.e. through any one of the openings through the wall of the outlet portion.
  • the injector pipe extends through the inlet portion into the inner space.
  • the injector pipe extends through a wall of the inlet portion.
  • the wall of the inlet portion may have the same transversal shape as, and be concentric with, the wall of the outlet portion.
  • the inlet extends through the first end.
  • the injector pipe has a bottom end in the inner space, wherein the bottom end is closed.
  • the tube arrangement comprises an outlet member and a number of tubes connected to and extending between the header outlet and the outlet member.
  • the number of tubes may be one single tube or a plurality of tubes, for instance 2, 3, 4, 5, 6, 7, 8 or even more tubes.
  • the heat exchanger system comprises an outlet conduit configured to discharge the fluid from the tubes via the outlet member, a steam drum connected to the tube arrangement via the outlet conduit and configured to receive steam and water of the fluid that has been heated from the tube arrangement, a steam consumer connected to the steam drum via a steam conduit, and configured to receive steam from the steam drum, a hot well connected to the steam consumer and configured to receive water from the steam consumer, an inlet conduit connecting the steam drum to the header inlet and configured to convey the first fluid from the steam drum to the header inlet, and a feed fluid conduit connecting the hot well to the injector pipe and configured to convey the second fluid from the hot well to the injection pipe.
  • the feed fluid conduit connected to the injector pipe of the header device may replace both the down comer and the circulation pump of the prior art.
  • the heat exchanger system comprises a feed water pump for forcing the second fluid from the hot well to the injector pipe.
  • the object is also achieved by the method initially defined, which comprises injecting a second fluid into the header via an injector pipe connected to the header, thereby forcing, by means of an ejector action, the first fluid through the header outlet and into the tube arrangement together with the second fluid, the fluid to be heated comprising the first and second fluids, and conveying the fluid to be heated through the tube arrangement in heat exchanging relation with the high temperature fluid in the channel.
  • the method further comprises conveying steam and water of the fluid that has been heated from the tube arrangement to a steam drum, conveying steam from the steam drum to a steam consumer, conveying water from the steam consumer to a hot well, conveying the first fluid from the steam drum to the header inlet, and conveying the second fluid from the hot well to the injector pipe.
