Definitions

  • the invention relates to a gas cooler arrangement for cooling the reaction products of a coal gasification reactor according to the preamble of claim 1.
  • a North voltage is known from DOS 29 33 716th
  • a convective gas cooler shown there is flowed through from top to bottom in one go.
  • the quality and particle size of the coal to be gasified only a more or less large part of the ash particles are separated and discharged from the pressure vessel of the first gas cooler, while the rest of the ash particles reach the convective gas cooler.
  • Some of these ash particles settle on the tubes of the tube bundle and for the most part they are discharged from the convective gas cooler with the gas stream.
  • a special separator is required, which causes an additional pressure drop on the gas side.
  • connection of the heat-dissipating tubes to vertical tube panels that is to say in the direction of flow, prevents the flow cross sections from becoming clogged with ash particles.
  • Claim 3 takes into account the fact that the risk of clogging the flow cross-section is higher in the downward draft than in the upward draft because the gas contains more ash particles in the downward draft than in the upward draft.
  • Claim 6 shows a solution by means of which thermal stresses at connection points of the riser walls on the fall train walls are excluded by avoiding such connection points.
  • the drop channel through which the cooled medium flows brings about an evening of the temperatures in the pressure vessel shell.
  • Claim 8 is a structurally and technically particularly simple solution.
  • Claim 11 shows a solution with a good thermodynamic effect and an easy to maintain arrangement.
  • Claim 12 specifies a particularly easy to operate system.
  • FIG. 1 shows a coal gasification reactor 1, to which a circular cylindrical pressure vessel 4 is connected via two nozzles 2, 3 and has an axial drop chamber 6 within a circular cylindrical radiation cooling wall 5.
  • a water bath 8 is provided, which can be washed off via a discharge element 9.
  • cooling wall openings 5 provided in a limited by the back of the radiant cooling wall 5 and a further cylindrical cooling surface 11 S hausenraum lead 10th Details of such a pressure vessel with an axial drop space and with a water bath are shown, for example, in CH patent applications 7051 / 80-2 and 7052 / 80-4, both filed on September 19, 1980.
  • a line 14 penetrating the wall of the pressure vessel 4 is connected, which leads via flanges 15 to a convective gas cooler 20.
  • This gas cooler consists of a pressure vessel 21 which encloses a drop train 23 and - as can be seen in FIG. 2 - two risers 24, 25 and an annular space 26. Fall train 23 and ascent trains 24, 25 are connected to one another at their lower end by a funnel-like deflection space 28. The lower end 30 of the deflection space 28 leads to a closing element, not shown.
  • the drop train 23 is limited in horizontal section by two long side walls 32, 33 and two short walls 34, 35, which walls are formed from vertical fin tubes which are welded gas-tight.
  • the fall train is divided into three equal-width chambers by two partition walls 37 and 38, which are also formed from welded fin tubes.
  • the intermediate walls 37 and 38 consist, for example, of fin tubes which are only welded in places and which can each be bent out and welded to the side walls 32 and 33 for lateral support 1 , which is not shown.
  • the tubes of the side walls 32, 33 and the walls 34, 35 are connected to a lower distributor 40 and an upper header 41, while the tubes of the intermediate walls 37 and 38 start from a distributor 44 and lead to a collector 45.
  • the collector 41 and the pipes that open into it are spanned in an upper region, in which the pipes are not connected to one another in a gas-tight manner, by a gas-tight hood 47, which is tightly connected all around to the walls 32 to 35 at the level of the collector 45.
  • the hood 47 is of lines 48 and 49 leading from the collectors 41 and 45 to a drum 50 of a steam generator, penetrated (F ig. 1).
  • U-shaped wall plates 55, or 56 are approximately gas (Fig.2), tightly connected (Fig.2), whereby the risers 24, 25 are formed.
  • Three tube sheets 58, 59 are suspended in each of these risers, each of which is formed by five meandering tubes that span the entire, larger horizontal extent of the risers.
  • the line 14 connecting the pressure vessel 4 to the pressure vessel 21 is connected to the drop train 23 through the short wall 34.
  • the walls of these trains have funnel-shaped sheet metal walls along a cross-shaped contour, which enclose the deflection space 28.
  • pipe sockets 70, 71 lead to internally insulated outlet sockets 72, 74 of the pressure vessel 21.
  • the upper ends of the pipes forming the tube sheets 58, 59 are connected to a collector 75 which is connected to an axial socket 76 which sits on the pressure vessel 21.
  • the gas After flowing through the fall train 23, the gas is deflected at a temperature of about 450 ° C. into the risers 24, 25, while the majority of the ash 28 and slag particles still present are thrown into the funnel of the deflection chamber g .
  • the gas is then cooled further in the risers 24, 25. It then emerges from the convective gas cooler 20 through the connecting pieces 73, 74, be it for direct use as fuel gas or process gas or into a further cooler which can be connected upstream of the drum 50 as an economizer of the steam generator.
  • the working medium of the steam generator passes from the drum 50 through the lines 52 and 53 into the distributors 40 and 44 and flows from there through the tube walls 32 to 35, at least partially evaporating, and then into the collectors 41, 45 and from there into the Drum 50 back, in which water and steam are separated.
  • the working fluid then flows via lines 62, 63 to distributors 60 and 61, and from there via the meandering pipes of pipe panels 58 and 59, in which it is overheated , to collector 75. From this collector it flows to a reheater or di right for use, be it as motive steam in a thermal power plant or as process steam in a chemical plant.
  • the invention is not limited to the exemplary embodiment shown in the drawing.
  • the number of tubes of the individual heating surfaces, the ratio of the tubes to the fall train 23 or the risers 24, 25, the number of tube boards 58, 59, the number of chambers, etc. can vary from the values shown. It may also be expedient to connect the sheet metal walls 55, 56 to the side walls 32, 33 via sliding seals, to install expansion folds on the sheet metal walls mentioned, to connect the sheet metal walls 55, 56 to each other around the drop cable 23, so that no connections to the Side walls 32, 33 become necessary.
  • the application of insulation to the sheet metal walls 55, 56 can also be expedient.
  • the number of ascents is also not limited, although it is advisable to choose a symmetrical arrangement.
