Definitions

  • the present invention relates to a tubular wall assembly comprising a plurality of tubular conduits in parallel arrangement interconnected to form a gastight structure, each tubular conduit being connected on one end to a common distributor and on another end to a common header, wherein through each conduit a flow path extends between the distributor and the header.
  • the invention also relates to an insertable flow restrictor for such a wall assembly and to a gasification reactor comprising such a wall assembly for the partial combustion of a carbonaceous feed, to a method of assembling such a reactor and to a method of operating such a reactor.
  • Such wall assemblies are particularly used as a wall for a burner unit in a gasifier for the production of synthetic gas or syngas by partial combustion of a carbonaceous feed, such as pulverized coal.
  • a carbonaceous feed such as pulverized coal.
  • An example of such a wall assembly is disclosed in GB 1 501 284 and WO 2008/110592.
  • water flows from the distributor into the parallel tubes and leaves the tubes as a mixture of water and steam when it flows into the header. This way, heat evolved in the gasification process is partly recovered in the gasification zone itself. For a safe cooling an even distribution of the cooling water over the parallel tubes is required.
  • the water distribution is improved by using strainer tubes having one end provided with an orifice.
  • the end with the orifice is inserted into an opening in the distributor line facing the inlet opening of the corresponding tubular line.
  • After inserting the strainer tube it is kept in place by a matching pin with a screw head forming a threaded connection with a threaded portion of the opening in the distributor wall.
  • This solution can only be used if the tubular lines are at sufficient distance from each other, since the screw heads are wider than the tubular lines and the openings in the distributor line would seriously weaken the wall of the distributor line.
  • the diameter of the openings in the distributor wall should be large enough to receive the screw threaded part, which is wider than the diameter of the strainer tube. This larger diameter further weakens the distributor wall.
  • the object of the invention is achieved with a tubular wall assembly comprising a plurality of tubular conduits in parallel arrangement interconnected to form a gastight structure,
  • each tubular conduit being connected on one end to a common distributor and on another end to a common header
  • each flow path passes a passage opening in a seat for an insertable flow restrictor
  • each conduit comprises an opening bordered by a collar with an open end in line with the seat
  • the parallel tubular conduits can for example be vertical or they can be helically wound.
  • the conduits are interconnected to form a gastight wall, e.g., as a tube-stay-tube or fin-tube construction.
  • the wall assembly can for example be cylindrical or it can have any other type of tubular geometry, e.g., being square or polygonal or elliptical in plan view.
  • the flow restrictors can for instance be provided with a strainer tube having one end provided with a nozzle with an outer surface matching the seat and with an opening or orifice, wherein the strainer tube is provided with a plurality of openings having in total a larger accumulated flow-through capacity than the orifice.
  • the orifice can for example be formed by an inwardly flanging end surface of the nozzle.
  • the strainer tube protects the orifice against plugging by foreign material.
  • the orifice can for example comprise a frusto-conical plug portion while the seat comprises a matching frusto-conical receptacle portion.
  • the orifice can be connected to the seat by a threaded connection.
  • a tensioned compression spring is arranged between the flow restrictor and the cap to push the flow restrictor against its seat.
  • the flow restrictor can be configured to maintain a desired pressure drop in the tubular wall assembly between the distributor and the header.
  • a pressure drop between 0.15 and 0.75 MPa has been found to be particularly advantageous for the process of steam generation.
  • the openings in the wall assembly for insertion of the flow restrictors can for example be arranged in the distributor opposite the proximal end of the corresponding conduit.
  • the openings can be arranged in the wall of the corresponding conduit.
  • the collar may have a longitudinal axis at an acute angle with the longitudinal axis of the conduit in flow direction.
  • the gastight tubular wall assembly is particularly suitable for use as a burner wall in a reactor for gasification of a carbonaceous feedstock.
  • a gasification reactor comprises a pressure vessel, at least one gasifier unit confined by the tubular burner wall assembly within the pressure vessel, wherein at least one burner is arranged to heat up the interior of the gasifier unit.
  • Such a carbonaceous feedstock gasification reactor can for example be built by first arranging the tubular wall assembly within the pressure vessel without the flow restrictors. Subsequently the open ended collars are closed off. After that, the distributor, the conduits and the header are flushed and/or boiled out. Then the caps are removed from the open ended collars, the flow restrictors are positioned, and the caps are put back to close off the open ended collars. Optionally, the caps are welded to the open ended collars.
  • the carbonaceous feedstock gasification reactor can for example be operated by providing water via the distributor to the tubular conduits, where it is heated to form steam. The steam is then discharged from the tubular conduits via the header.
  • the flow restrictor as described above, it is possible to maintain a pressure drop in the water between the distributor and the header between 0.15 and 0.75 MPa by adjusting its flow-through capacity.
