Definitions

  • the present invention relates to a tube heat exchanger placed in a high temperature fluid and comprising tubes connected to an inlet manifold and to an outlet manifold.
  • FR-A-2,449,845 discloses a heat recovery boiler comprising a plurality of exchange elements formed from tubes convoluted in vertical coils. This design poses problems in particular with regard to support.
  • the present invention as characterized in the claims aims to solve the problems of expansion and support for a bundle of tubes of the above type, placed in a fluid at a very high temperature, in particular in a flow of hot gas. or hot smoke or in the fluidized bed of a combustion appliance.
  • the adopted design allows to keep the pitch between the turns formed by the tubes and avoids the twist and the vibrations of these tubes. This design further limits the fouling phenomenon when the fumes are loaded with dust.
  • the exchanger according to the invention is characterized in that it comprises a plurality of panels made up of tubes extending under two inlet manifolds and two outlet manifolds to which they are connected upstream and downstream, forming two half-panels nested one inside the other, each half-panel consisting of a sub-collector tube connected to an input collector and to which is connected at least one tube circumvented in a lace so that the two tubes under -collectors extend vertically inside the envelope of said lace-up tubes and they support them by means of cantilever supports.
  • each turn of the lace tube rests on two supports fixed to the two sub-collector tubes.
  • the inlet and outlet collectors extend horizontally and the two outlet collectors are situated at the same height relative to each other and above the two inlet collectors which -same are located at the same height relative to each other.
  • the tubes in laces starting from a sub-collector tube are wound between the turns of the tubes, in laces starting from the second sub-collector tube, the directions of winding being the same.
  • the exchanger shown in particular in FIGS. 1 and 2 is placed in a fluid at an elevated temperature, in particular in a solid-gas mixture of the fluidized bed of a fluidized bed apparatus or also in a stream of hot gas or hot fumes coming from example of a gas turbine furnace or combustion chamber.
  • the fluid solid-gas, gas or smoke mixture
  • the gas or smoke stream flows vertically upward according to arrow 11.
  • the embodiment shown comprises two bundles of tubes referenced 6 and 7 respectively.
  • Each bundle comprises a pair of inlet manifolds 21, 22 which receive a relatively cold gas and a pair of outlet manifolds 31 and 32 which collect the hot gas after it has passed through the tubes 41 to 48.
  • the collectors 21, 22, 31, 32 pass through a wall of the enclosure or of the conduit and extend horizontally, substantially up to the opposite wall.
  • the inlet collectors 21 and 22 are located substantially at the same height relative to each other.
  • the outlet collectors 31 and 32 are located substantially at the same height relative to one another.
  • the outlet manifolds 31 and 32 are located above the inlet manifolds 21 and 22 (that is to say downstream relative to the direction of flow 11 of the hot gas).
  • the spacing between the outlet manifolds 31 and 32 is substantially equal to the spacing between the inlet manifolds 21 and 22.
  • the inlet collectors 21 and 22 are supported at their ends by the enclosure or the duct 1. They support, via spacers 51 and 52, the outlet manifolds 32 and 31 respectively, the entire beam being suspended.
  • the inlet manifolds 21 and 22 for the cold gas constitute the support structure for all of the bundles.
  • Each bundle consists of a plurality of tubular panels 4 extending vertically next to each other and which consist of tubes 41 to 48 extending under two inlet manifolds 21 and 22 and two outlet manifolds 31 and 32. These tubes are connected upstream to the pair of inlet collectors 21 and 22 and downstream to the pair of outlet collectors 31 and 32.
  • Each panel 4 consists of two half-panels nested one in the other and each connected to an inlet manifold 21 or 22 and to an outlet manifold 31 or 32.
  • Each half-panel comprises an inlet sub-collector tube 41 or 42 connected under the inlet collector 21 or 22 respectively and which branches out by tubes convoluted in laces 43, 44, 45 or 46, 47, 48 respectively, these lace-up tubes opening into the outlet collector 31 or 32 which is associated with the inlet collector.
  • An outlet manifold such as 31 associated with the inlet manifold 21 in a half-panel is located above the inlet manifold 22 of the other half-panel.
  • the lace tubes 43 to 45 or 46 to 48 are connected to the lower part of a sub-collector tube 41 or 42 which extends vertically under the inlet collector to which it is connected.
  • the lace-up tubes 43 to 48 are bypassed so that their axes form "flattened helices" centered on an axis constituting the vertical axis of symmetry of the two sub-collector tubes 41 and 42. These two sub-collector tubes 41 and 42 are located inside the fictitious cylinder enveloping the lace tubes 43 to 48 which therefore surround said sub-collector tubes.
  • the lace-up tubes such as 43 to 45 starting from a sub-collector tube 41 are wound in the interval extending between the turns of the lace tubes 46 to 48 starting from the second sub-collector tube 42 so that these tubes are nested one inside the other, the winding direction of the tubes 43 to 45 being the same as that of the tubes 46 to 48.
  • These lace-up tubes 43 to 48 are wound so as to present rectilinear parts connected by elbows. They form on each side of the sub-collector tubes 41 and 42 a series of rectilinear sections. They are wound with a pitch such that there is an interval between each tube and the neighboring tube.
  • Each lace tube 43 to 48 is, in an elbow, in contact with two opposite generatrices of a sub-collector tube. In each bend, the underside of the tube is separated from the sub-collector tube neighbor so as to allow for expansion.
  • Each sub-collector tube 41 or 42 has, along a generator, a series of cantilever supports 411 and 421 respectively. These cantilever supports are fixed at regular intervals along a generatrix of each sub-collector tube.
  • the lace tubes 43 to 48 are supported on these cantilever supports 411 and 421.
  • Each turn of a lace tube is supported by two supports 411 and 421 fixed to the two tubes under collectors.
  • the supports 411 and 421 are arranged in each of the intervals between two lace tubes. These supports are made of metal and are welded to the tubes under collectors. As a variant, these supports could be constituted by ceramic rings encircling the sub-collector tubes.
  • the exchanger is used to heat a relatively cold gas which is brought to the inlet manifolds 21 and 22.
  • the cold gas to be heated descends in the tubes under collectors 41 and 42 then circulates in the lace tubes 43 to 48 before being collected in the outlet collectors 31 and 32. During this course, the gas circulating in the tubes recovers the heat from the fluidized bed or hot gas outside the tubes.
  • the exchanger is placed within the bed 8 of a fluidized bed boiler.
  • This exchanger constitutes an air heater and is placed upstream of the steam production bundle.
  • the air which enters the exchanger comes from a compressor and the hot air which leaves is sent to a gas turbine.
  • the exchanger is placed in a duct 1 which channels the very high temperature fumes coming from a gas turbine 9.
  • the air which enters the exchanger comes from the compressor of the turbine and the hot air that leaves is sent to the combustion chamber of the turbine.
