Definitions

  • the invention relates to a steam generator with fluidized bed combustion according to the preamble of claim 1.
  • Such a steam generator is known from FR-A 2 382 661, and the water and / or steam-carrying heating pipes arranged in the fluidized bed are designed as so-called flag heating surfaces, which consist of pipe coils or U-pipes bent back and forth in a meandering manner and by branch off the evaporator tubes of the combustion chamber and rejoin them. It has been shown that during the operation of the steam generator in these serpentine tubes of the flag heating surfaces, in particular when starting up and shutting down, very high stresses which can be attributed to uneven thermal expansion can occur, which the tubes cannot withstand in the long run. These voltages can become impermissibly high when a gas flows through the heater tubes.
  • the vertical legs have only a slight difference in elongation compared to the combustion chamber wall because of their short length; the long horizontal legs can therefore be easily supported.
  • the vertical legs bend, although they are short, by changing the length of the long legs in a still permissible frame. Since they carry their own weight, they do not have to be supported; rather, they still bear part of the weight of the horizontal legs.
  • the horizontal legs of the heater tubes are supported very simply and reliably by cooled support tubes according to claim 3.
  • Claim 5 specifies a solution in which minimal expansion differences occur between the support tubes and the combustion chamber wall.
  • Claim 6 teaches a particularly simple arrangement of support tubes, in which these tubes can form switched evaporator tubes of the steam generator in natural circulation.
  • the support tubes can be firmly connected to the horizontal legs of the heater tubes so that no sliding friction leading to wear and tear occurs at the support points.
  • the support tubes are expediently cooled here in a forced pass.
  • the U-pipes could be forked in the area of the deflection, so that a down pipe would communicate with several risers.
  • a slightly rising expansion loop could also be attached so that the support tubes could be drained when the steam generator was shut down.
  • air is heated from approximately 400 ° C. to approximately 800 ° C. in the heater tubes
  • the thermal expansion of the vertical legs remains closer to the thermal expansion of the combustion chamber wall; the distance between the heater tube crowns and the adjacent support points of the horizontal legs can thereby be selected to be shorter, so that the bending stresses in the area between the respective crown and the first support of the relevant horizontal leg are reduced.
  • the lower temperature of the vertical legs allows higher bending stresses in these.
  • combustion chamber 1 has a combustion chamber 1 with a rectangular plan, which is delimited by a front wall 2, a rear wall 3 and two side walls 4 and 5.
  • the base of the combustion chamber is formed by a bottom 6.
  • the walls 2 and 3 of the combustion chamber 1 are directly gas-tightly connected to walls 10 and 11 of a gas flue 14, whereas the walls 4 and 5 are gas-tightly connected to walls 12 and 13 of the gas flue via two inclined connecting wall surfaces 8 and 9, respectively.
  • the walls 2 to 5 of the combustion chamber 1, the connection wall surfaces 8 and 9 and the walls 10 to 13 of the gas flue 14 are formed from tubes 7 which are tightly welded to one another.
  • a main distributor 16 runs in the middle below the bottom 6 of the combustion chamber 1 and is supplied with water of almost full condition via two down pipes 17 and 18 from a drum 20.
  • a side wall distributor 22 and 23 is connected at the foot of the side walls 4 and 5.
  • the tubes 7 of the side walls 4 and 5 of the combustion chamber, of the connecting wall surfaces 8 and 9 and of the side walls 12 and 13 of the throttle cable 14 extend from the two side wall distributors and open into side wall collectors 27 and 28 respectively.
  • twelve curved connecting pipes 29 lead in pairs six support tube distributors 30, 30 ', 30 "located in the base 6.
  • Bottom tubes 32 are arranged between two support tube distributors 30 and between the side wall distributor 22 and 23 and the adjacent support tube distributor 30' and 30", which together and with the adjacent distributors 30 , 30 ', 30 "and 22, 23 are connected via passages 33 leaving free webs 34.
  • the bottom tubes 32 open into those tubes 7 which form the front wall 2 and the rear wall 3 of the combustion chamber. These tubes 7 sit in the walls 10 and 11 of the throttle cable and lead into a front collector 40 or rear collector 41; these two collectors are connected to the side wall collectors 27 and 28 en, of which the collector 27 is connected to the drum 20.
  • the bottom pipes 32 are each connected to the main distributor 16 via a K-piece 42 and two pipe bends 43 (FIG. 4). As can be seen from FIG.
  • support tubes 46 branch off from the support tube distributors 30 at equal distances from one another or from the front and rear wall 2. 3. These tubes 46 lead vertically upwards and open in the gas cable 14 in support tube collectors 48, which are connected to the drum 20 via transverse collectors 49 and 50 located outside the cable 14 and two connecting lines 51. The two outermost support tube distributors 30 'and 30 "lie below the connection wall surfaces 8 and 9. The support tubes 46 emanating from them open, as shown in FIG. 1 on the right, in a tube 7 of the connection wall surface 9. From the mouth of the support tube concerned from the top, the tubes 7 have a larger cross section than the other tubes 7 of the side walls 4, 5, 12, 13.
  • L-shaped heater tubes 52 and 53 extend in vertical planes, which start from distributors 54 and 55 and open into the collector 56 and 57, respectively.
  • the heater tubes penetrate the connection wall surfaces 8 and 9 with their short vertical legs 58 and 59 and the side walls 5 and 4 with their long, approximately horizontal legs 60 and 61.
  • At least one of the tubes 7 of the side walls is at the penetration points 4, 5 and the connecting wall surfaces 8, 9 are bent out of the wall plane in the usual way. Appropriately welded bars ensure the tightness of the walls at the penetration points.
  • the heater tubes 52 and 53 are each slidably supported on the support tubes 46 at five locations on their long legs 60 and 61, respectively, via U-shaped support loops 62 (FIG. 3).
  • the support tubes 46 are symmetrical about their axis by carrying loops.
  • An air box 63 is provided below the combustion chamber floor 6. It consists of a trough plate 64 of rectangular outline, which is connected to the periphery of the combustion chamber base 6 in a gas-tight manner via expansion elements 65. The air box 63 thus formed is connected via a nozzle 67 to a combustion air source, not shown.
  • a superheater tube bundle 70 is arranged above the combustion chamber 1, the upper end of which is connected to the steam chamber of the drum 20 via a distributor 72 and two connecting lines 71 and which is connected to a live steam line 80 at a lower end via a collector 79.
  • an economizer tube bundle 74 is provided in the throttle cable 14 and is connected to a feed line 76 via a distributor 75.
  • the outlet of the economiser tube bundle 74 is formed by a collector 77, which is connected via a line 78 to the water space of the drum 20.
  • a gas duct 39 leading to an air preheater (not shown) is connected to the collectors 27, 28, 40 and 41 which are arranged at the upper end of the throttle cable 14 and form a ring collector.
  • the steam generator is supplied with air via the nozzle 67 of the air box 63.
  • the air rises through the passage openings 33 provided in the combustion chamber floor 6 and through the fluidized layer of coal, lime and slag particles lying above it. Due to the contact of the glowing coal particles and the intense turbulence of the combustion gases, a very good heat transfer is achieved on the heating pipes 52 and 53.
  • the heater tubes can therefore also contain catalytes or be coated on the inside with such.
  • the heater tubes 52 and 53 can also be connected in series instead of in parallel, e.g. B.
  • the Collector 56 is connected to the distributor 55.
  • feed water is fed to the steam generator via the feed line 76. This is preheated to almost evaporation temperature in the economiser tube bundle 74 and introduced into the drum 20.
  • water passes from the drum 20 into the main distributor 16 below the floor 6.
  • a first part of the water flows via the side wall distributors 22 and 23 into the pipes 7 of the side walls 4 and 5 and then arrives as Steam / water mixture via the side wall collectors 27 and 28 into the drum 20.
  • a second part of the water flows from the main distributor 16 via the pipe bends 43, the K-pieces 42 and the bottom pipes 32 into the pipes 7 of the front and rear walls 2 and 3.
  • the water flows on the one hand over the inclined outer edges of the connecting wall surfaces 8 and 9 along collectors (not shown) and risers (also not shown) and on the other hand as steam / water mixture via the collectors 40 and 41 back into the drum 20.
  • a third part of the water flows from the main distributor 16 into the support pipes 46.
  • the steam / water mixture formed therein passes through the support pipe collectors 48, the cross collectors 49, 50 and the two connecting lines 51 into the drum 20.
  • Saturated steam from the steam chamber of the drum 20 then flows via the two connecting lines 71 into the superheater tube bundle 70, from which it reaches the live steam line 80 as superheated steam, which leads to a consumer (not shown).
  • air is heated in the heating tubes 52 and 53 from, for example, 400 ° C. to 800 ° C., which is fed to a gas turbine as a working medium.
  • the relatively high temperature of the air in the horizontal, long legs 60 and 61 of the heater tubes 52, 53 has the consequence that these legs expand relatively strongly during operation. They slide in the U-shaped loops 62, and it may be expedient to provide the inside of the loops 62 and / or the outside of the legs 60, 61 in the region of the sliding points with a means which prevents or reduces wear.
  • the agent can be applied, for example, by plasma spraying.
  • the vertical legs 58 and 59 of the heater tubes 52, 53 assume considerably lower temperatures than the horizontal legs because on the one hand they are traversed by colder air and on the other hand are only partially heated by flue gas, which results in a lower heat transfer on the heating medium side. Accordingly, the vertices between the short and long legs move almost only in the horizontal direction relative to the tubes of the side walls 4, 5. Since approximately the same temperatures occur in these tubes as in the support tubes 46, the support points of the heater tubes 52, 53 remain at approximately the same height relative to the penetration points. The suspension of the heater tubes can therefore be described as ideal.
  • heating tubes 52 and 53 are supported on the support tubes 46, on both sides at the same heights, which originate from the same distributor 54 and 55 and lead into the same collector 56 and 57.
  • Five such support tubes together with twelve heater tubes 52 or 53 attached to them form a tube sheet.
  • Successive tube sheets are alternately arranged in the combustion chamber 1 in such a way that the vertical legs 58 of the heater tubes 52 of the side wall 4 and the vertical legs 59 of the heater tubes 53 are adjacent to the side wall 5.
  • the support tubes can form simple U-tube loops or the loops can be branched; the latter is shown in FIGS. 5 and 6.
  • a down pipe 89 which carries twelve heater pipes 52 from the distributor 54, leads to a horizontal pipe 81, from which three risers 83 branch off, which also each carry twelve heater pipes 52 from the distributor 54.
  • the riser pipes 83 lead into the support pipe collector 48.
  • a down pipe 85 is arranged, from which twelve heater pipes 53 are carried out of the distributor 55 and which leads to three riser pipes 87 via a horizontal pipe 86 which are each supported by twelve heater tubes 53 from the distributor 55.
  • the support tubes 89, 83 and 85, 87 can perform opposite pendulum movements corresponding to the elongations of the long legs 60 and 61, respectively. Signs of friction are thus avoided.
  • Lichen vertical dividers which may also have the role of dividing the combustion chamber into compartments; such a subdivision would have significance for part-load operation.
  • the support tube collectors 48 are arranged between the economizer tube bundle 74 and the superheater tube bundle 70, they can also — as FIG. 5 shows — be arranged in the region of the superheater or even below it. In the latter case, it may be advisable to support these low-hanging support tube collectors from a few higher support tubes from higher-hanging collectors. This support can also be done from sloping draft tubes from high points of the throttle cable walls.
  • the heater tubes 52 and 53 are attached to the support tubes 89, 83 and 85, 87 in a staggered arrangement.
  • the steam generator contains, among other things, means for introducing the preferably granular fuel and optionally additives to form the fluidized bed and / or bind pollutants, e.g. B. Lime for binding sulfur. It also has means for discharging and / or recirculating fuel, additives and / or recirculation products, which means are also not shown here.
  • means for introducing the preferably granular fuel and optionally additives to form the fluidized bed and / or bind pollutants e.g. B. Lime for binding sulfur.
  • It also has means for discharging and / or recirculating fuel, additives and / or recirculation products, which means are also not shown here.
