Definitions

  • the present invention relates to a heat exchange bank suitable for realizing a heat exchange between at least two fluids at different temperatures. More specifically, the present invention relates to heat exchange banks as defined in the preamble of claim 1, and as illustrated in US 5 787 722 .
  • Exchange banks are typically used to transfer the energy possessed by a hot, i.e., higher temperature, gas flow, normally from an industrial process, to a cold, i.e., lower temperature, fluid circulating within heat exchange elements that make up the banks.
  • gases from industrial waste combustion plants are often used as the hot gas flow.
  • the cooling fluid contained within the elements is a subcooled liquid, a two-phase, saturated liquid-saturated steam mixture, or a superheated steam, in a pressure range generally between 10 and 80 bar and a temperature range between 120°C and 500°C.
  • Hot gases usually range in temperature from about 100°C to 1200°C and, since they come from industrial combustion processes of municipal and/or industrial waste, they contain diffuse ash in their mass, typically between 0.5 gr/Nm3 and 20 gr/Nm3.
  • a tube bundle that is simultaneously traversed internally by a first, lower temperature fluid, called a cooling fluid, and lapped externally by a second, higher temperature fluid, typically a gas.
  • the ash contained in the hot gases tends to foul the heat exchange surfaces of the heat exchange elements, i.e., the outer surfaces of the tubes in the tube bundle, undermining the heat exchange between the two fluids and irreparably compromising the performance of the banks.
  • Cleaning operations involve cooling the bank, replacing replaceable parts by destructive cutting, and removing dust from heat exchange surfaces by mechanical abrasion or shaking.
  • the object of the present invention is to make available a heat exchange bank capable of solving the problems mentioned in reference to the prior art.
  • 4' , 4' ' , 4' '' globally denote a heat exchange bank, suitable for realizing heat exchange between a first and second fluid at different temperatures.
  • 4' denotes a vaporizer heat exchange bank, 4" a superheater heat exchange bank, and 4′′′ an economizer heat exchange bank.
  • vaporizer, superheater, and economizer heat exchange banks apply depending on whether the fluid flowing through the tube bundle is a two-phase, saturated liquid-saturated steam mixture, superheated steam, or subcooled liquid, respectively.
  • the heat exchange bank 4 comprises a heat exchange apparatus 6 provided with a tube bundle 8 suitable to be traversed internally by said first fluid, support means 9 of the tube bundle 8 to the heat exchange apparatus 6, and containment means 10 of said second fluid suitable for accommodating said heat exchange apparatus 6 so that at least a portion of said tube bundle 8 is lapped externally by said second fluid.
  • the support means 9 are structurally distinct from said containment means 10, and an upper end 12 of said tube bundle 8 is operatively connected thereto.
  • the support means 9 comprise at least one chain 60 comprising a plurality of links 61 concatenated in series with each other, said chain extending parallel to the tubes of the tube bundle 8.
  • said at least one chain 60 is provided with an anti-rotation device 62 configured so as to prevent or at least limit a rotation of the chain 60 and of the tube bundle 8 about an axis of rotation parallel to said tubes.
  • said at least one chain 60 is provided with at least one threaded tie rod 63, at least partially fixed on an upper cross member 64.
  • Said threaded tie rod 63 allows an adjustment of the height of the various chains 60 in order to improve the flexibility characteristics of said heat exchange bank 4. It should be noted that said adjustment may advantageously be carried out externally to the flue gas loop. In other words, since the threaded tie rod 63 is external to the flue gas loop, an operator has free access to it from the outside.
  • said tube bundle 8 preferably extends along a prevailing direction Z.
  • said prevailing direction Z is substantially perpendicular to a support plane A on which said bank rests.
  • the support plane A is horizontal, and the prevailing direction Z is vertical.
  • the tube bundle 8 comprises a plurality of tubes parallel to each other, which, according to a possible embodiment, extend substantially in a vertical direction, i.e., perpendicular to said support plane A of the bank and parallel to said prevailing direction Z.
  • the tubes of the tube bundle 8 are suitable to be traversed internally by a first fluid such as a subcooled liquid (economizer bank) or a two-phase, saturated liquid-saturated steam mixture (vaporizer bank) or superheated steam (superheater bank), having a temperature between approximately 120°C and 500°C and a pressure between 10 bar and 80 bar in the normal operating ranges of heat banks.
  • a first fluid such as a subcooled liquid (economizer bank) or a two-phase, saturated liquid-saturated steam mixture (vaporizer bank) or superheated steam (superheater bank), having a temperature between approximately 120°C and 500°C and a pressure between 10 bar and 80 bar in the normal operating ranges of heat banks.
  • Said tubes are preferably made of metallic materials, which are able to ensure mechanical and thermal resistance of the tubes under normal operating conditions, but also an adequate heat transfer coefficient, without, however, requiring excessive wall thicknesses of the tubes, so as not to overburden the structure of the bundle.
  • said exchange apparatus 6 comprises at least one distribution manifold, fluidly connected to said tube bundle 8.
  • the at least one distribution manifold comprises an inlet suitable for receiving and conveying the first fluid within said manifold.
  • Each distribution manifold is fluidly connected to a plurality of tubes of the tube bundle so that a fluid in the tubes may be distributed through said inlets.
  • the fluid circulates within the tubes of the tube bundle 8 so that it enters through at least one inlet and exits through at least one outlet.
  • said at least one inlet and said at least one outlet are located on the same side of the tube bundle 8, that is, at said upper end 12.
  • outlets and inlets of the tube bundle 8 are preferably located at the upper end 12 of the tube bundle 8.
  • the tubes of the bundle 8 extend in a coil along said prevailing direction Z.
  • said tube bundle 8 extends at least in part along a broken line that forms a series of alternately protruding and receding angles.
  • the tubes extend predominantly in a direction parallel to the prevailing direction Z and perpendicular to the support plane A of the bank, for example, in a vertical direction from the upper end 12 to the lower end 22 of the tube bundle and vice versa.
  • the tubes comprise straight segments, according to an embodiment directed along the prevailing direction Z, connected to each other by curves or sines or circumferential arcs extending along a direction substantially perpendicular to said prevailing direction Z.
  • the first fluid inside said coil after traveling in one direction along a straight tube segment, having arrived at one end of the bundle, travels along a curved tube segment and reverses the motion, i.e., travels, in an opposite direction, along a subsequent straight segment of an adjacent tube, and so on.
  • each coil of said tube bundle extends in turn according to a curve forming a series of alternately protruding and receding angles, or according to a curve forming a series of alternately concave and convex arcs.
  • each tube of the tube bundle coil is offset with respect to the consecutive adjacent tube, in such a way, however, that the tubes are maintained in an aligned configuration.
  • said tube bundle 8 is structurally connected to a containment box 26 of the heat exchange apparatus 6.
  • Said containment box 26 is arranged at the upper end 12 of the tube bundle 8 operatively connected to the support means 9 and, according to a possible embodiment, is made according to a substantially box-like and hollow structure, so as to enclose and wrap around said upper end 12 of the heat exchange apparatus 6.
  • said containment box 26 encloses said support means 9.
  • the containment box 26 rests against said containment means 10.
  • the containment box 26 comprises a shell 28, which constitutes a side surface of the box, and a lid 30 that closes opposite ends of the shell 28.
  • Said lid 30 and said shell 28 are constrained to the frame 70 so as to form a closed box structure and extend substantially according to planes parallel to the support plane A and perpendicular to the prevailing direction Z of the tube bundle.
  • insulating means in the containment box 26, above the cooled canopy, insulating means and preferably panels of insulating material, such as ceramic material, are interposed.
  • Said cooled canopy is traversed by the tube bundle, and the interposition of the insulating means is such that gases are not able to leak into said canopy.
  • the tube bundle 8 is constrained to the heat exchange apparatus 6 exclusively at one end, i.e., outside of said end the bundle is not constrained to any structural element, i.e., the weight of said bundle rests entirely on the suspension systems present at an upper end 12 of the tube bundle 8.
  • the tube bundle is constrained at a single end so that it remains suspended, i.e., maintaining itself in a direction substantially parallel to the prevailing direction Z.
  • a frame 70 penetrated by cooling water is interposed between the containment box 26 and the tube bundle 8.
  • said frame 70 may be attached to the convective chamber frame 73 by a C-shaped centering structure 71.
  • the heat exchange apparatus 26 further comprises shaking means 51, better described below, suitable for striking the tube bundle 8 to carry out tube bundle cleaning operations.
  • said shaking means 51 are supported by the beams 64 by means of chains 60 and are associated with at least one shaking bar 52.
  • the sheet 53 is connected to the shell 28 and is mechanically independent of the shaking bar 52.
  • the tubes of the tube bundle 8 are connected to the shaking bar 52 by means of cantilever connections 54 arranged near the upper ends 12 of the tube bundle 8.
  • said cantilever connections 54 are welded to the tubes of the tube bundle 8 and to the shaking bar 52. In this way, the cantilever connections 54 are not affected by the elongation of the tubes of the tube bundle 8 due to the thermal stresses thereof.
  • the exchange apparatus 6 comprises coupling means 46 arranged at the end of the tube bundle 8 operatively connected to the support means 9.
  • said coupling means 46 comprise at least one lifting lug 47, suitable for coupling with suitable lifting means, to enable the handling of the tube bundle 8.
  • the heat exchange bank 4 comprises containment means 10 suitable for accommodating within them the exchange apparatus 6 so that at least a portion of the tube bundle 8 is lapped externally by the second fluid.
  • Said containment means 10 preferably extend according to the prevailing direction Z of the tube bundle 8 so as to surround and contain said bundle.
  • the heat exchange apparatus 6 is advantageously supported on said containment means 10.
  • the term "supported” means that the exchange apparatus 6 rests on a portion of the containment means by bearing thereon with its own weight, and thus is supported by them without further restraint.
  • said exchange apparatus 6 also comprises a cleaning system of the tube bundle 8.
  • said cleaning system is a shaking system, which realizes the cleaning of the surfaces of the tube bundle as a result of direct or indirect striking of said tube bundle.
  • said cleaning system is mounted near said upper end 12 of the tube bundle 8, preferably within said containment box 26, if provided.
  • the cleaning system comprises bars that are welded or otherwise made integral to the elements of the tube bundle.
  • said shaking bars 52 are made integral with or connected to each other.
  • a battery of shakers is suitable for striking said shaking bars 52 so as to vibrate the elements of the tube bundle 8.
  • At least one hopper 56 is arranged at the lower end 22 of the tube bundle 8, said hopper being provided with at least one septum 57 configured to avoid preferential gas paths within the containment means 10 of the second fluid.
  • the heat exchanger banks described are used in any type of partial or total recovery plant, in other words, they are heat exchange devices, or heat exchangers or heat transformers, adapted to utilize the residual heat content of a fluid discharged from a plant of any type.
  • the flue gas produced by the incinerator furnace constitutes the "hot" fluid, in other words, the second fluid having a residual heat content that is intended to be recovered, transferring it to the first fluid with a lower temperature, called the cooling fluid.
  • thermo-destruction of waste are rich in toxic or polluting dust and therefore must be purified in order to be released into the atmosphere.
  • the purifier filters may not filter said gases at high temperatures, because at such temperatures the toxic substances contained in the gases are extremely corrosive to the point of rapidly deteriorating the filters themselves.
  • the flue gases produced as a result of waste incineration are conveyed, according to a predetermined flue gas pathway, through the containment means, such as through properly insulated ducting systems to limit heat loss.
  • the heat exchange banks disclosed in the present invention are arranged along said path.
  • the conveyor systems extend according to a horizontal direction, i.e., parallel to the support plane or base of the plant, while the exchange banks are developed according to a vertical direction, i.e., perpendicular to the direction horizontal to the support plane of the plant.
  • Said banks thus allow heat exchange between the flue gases and a cooling fluid that flows, through natural or forced circulation, within the tube bundles.
  • the first fluid or cooling fluid used is water in different physical states, and specifically in the form of a saturated liquid-saturated steam mixture, superheated steam, or subcooled liquid, depending on whether they are vaporizer banks 4', superheaters 4", or economizers 4′′′, respectively.
  • the first fluid circulating within the tube bundle increases in temperature and may then be conveyed for a variety of uses, such as a motor fluid in steam turbine systems or to feed a thermal utility.
  • the heat exchange banks according to the invention make it possible to overcome the drawbacks presented in exchange banks of the prior art.
  • the heat exchange banks described are removable with very simple operations, and the removal operation does not require any destructive cutting of sheets or pressure parts in general, but rather the removal of threaded connections on the supporting flanges of the bank with the heat exchange fluids.
  • An additional advantage relates to cleaning operations, as shaking systems of the prior art may be used with an amplified technical effect in heat exchange banks of the prior art.
  • the tube bundle is constrained to the bank structure in a rigid manner so that, when subjected to a hammering action, the relevant tubes of the bundle vibrate modestly and the amount of dust removed is relatively little, for the same hammering action.
  • the disclosed tube bundle due to the described constraint systems, possesses considerable elasticity in operation without any need to be disconnected from the exchange bank.
  • the arrangement of the tubes which, with respect to a plane perpendicular to the preferential direction of the bundle, extend according to a curve that forms alternately protruding and receding angles, is particularly advantageous.
  • This configuration while giving the tube bundle high flexibility and thus an effective and rapid cleaning of the tube bundle by the shaking systems, is able to ensure proper relative positioning between the tubes of the bundle during the operation of the exchange bank, so as not to affect the proper heat exchange between the tubes and the external fluid.
  • the described tube bundle ensures high efficiency of the bank during all operating conditions, and enables rapid and accurate removal of the dust covering it, ensuring maximum cleaning efficiency.
