Definitions

  • the invention relates to a device for the gasification of finely divided, in particular solid fuels with oxygen-containing gases under increased pressure, in which the gasification reactor is designed as a pipe wall construction which is exposed to cooling water and is surrounded by a pressure jacket at a distance.
  • Such a device is known from DE-AS 24 25 962.
  • This requires a large number of supply and discharge lines to and from the individual cooling circuits of the pipe wall construction which penetrate the pressure jacket.
  • the invention is therefore based on the object of cost-effectively simplifying the installation of the type described at the outset while increasing operational reliability.
  • the cooling water outlets of the cooling circuits of the pipe wall construction open into the water-filled space between the pipe wall construction and the pressure jacket, this room, which is provided with a cooling water discharge line passing through the pressure jacket, being separated from the interior of the pipe wall construction in a gas-tight and watertight manner.
  • Another advantage of the proposed embodiment of the gasification device is that only the cooling water supply lines to the individual cooling circuits of the tube wall construction and the common cooling water discharge line have to be provided as lines penetrating the pressure jacket and connecting these and the tube wall construction. Separate cooling water discharge lines from the individual cooling circuits, which also had to be led through the pressure jacket in conventional gasification devices, are eliminated.
  • the invention also proposes that the cooling circuits of the pipe wall construction be provided with forced circulation. This ensures reliable cooling at every point in the pipe wall construction.
  • the forced circulation enables any pipe routing and pipe reversals.
  • the water-filled space between the tube wall structure and the pressure jacket should preferably have a higher pressure than the interior of the tube wall structure. This creates additional security against the outflow of production gas from the gasification reactor in the direction of the pressure jacket if damage occurs.
  • the invention further provides that the cooling water supply lines of the cooling circuits of the pipe wall construction and the cooling water discharge line pass through the upper part of the pressure jacket, which can be detached by means of a flange connection, and this part of the pressure jacket can be lifted off from the lower part of the pressure jacket together with the complete pipe wall construction attached to it . This considerably simplifies repair and maintenance work on the pipe wall construction or on the inside of the pressure jacket.
  • the pipe wall construction is connected to the pressure jacket at its upper and / or lower end by means of compensators.
  • 1 designates the tube wall construction as a whole, the interior 2 of which is the gasification reactor.
  • Several burners 3 open into the gasification reactor, only one of which is shown in the drawing.
  • the tube wall construction 1 is surrounded at a distance by a pressure jacket 4, which is divided into an upper and a lower part 4a or 4b by the flange connection 5.
  • the lower part 4b of the pressure jacket has in the interior a plurality of supports 6 distributed over the circumference, on which the tube wall structure with brackets 7 fastened to it is locked and centered.
  • the tube wall structure 1 is connected to the upper part 4a by means of a suspension structure 8, which permits thermal expansion of the tube wall structure in the axial direction relative to the pressure jacket.
  • the tube wall construction 1 is composed of individual cooling circuits 1 a, 1 b, 1 c, 1 d and 1 e. Each of these cooling circuits has a separate cooling water supply line 9a, 9b, 9c, 9d and 9e, which in each case passes through the upper part 4a of the pressure jacket 4, as is shown in the case of line 9a.
  • the cooling water outlets 1oa, 1ob, 1 oc, 1 od or 1 oe open, as can be seen from the drawing, into the water-filled space 11 between the pipe wall construction 1 and the pressure jacket 4.
  • the space 11 has a cooling water discharge line 12 common to all cooling circuits on through the upper part 4a of the pressure jacket leads and is connected to a steam drum, not shown here.
  • the pressure in space 11 is preferably above the pressure of interior space 2.
  • the differential pressure should not be chosen too high in order to keep the load on the pipe wall construction low.
  • the pressure in the gasification reactor which is, for example, 4o bar, is thus essentially absorbed by the pressure jacket 4 with only a slight differential pressure, while the tube wall construction 1 is largely relieved of this.
  • a compensator is designated, which is connected on the one hand to part 1 of the tube wall construction and on the other hand to the upper part 4a of the pressure jacket in the region of the gas outlet 14.
  • Another compensator 15 connects part 1d of the pipe wall construction to the slag discharge shaft 16, which is attached to the lower part 4b of the pressure jacket.
