Definitions

  • the coat-welding of the RVS is carried out MIG welding and TIG disposed.
  • helical coat-welding means a.o., a weld bead extending continuous in radial circumferential direction in such a helical manner in axial direction, that succeeding windings of the weld bead mutually contact or (slightly) overlap with the adhacent longitudinal edges, such that a continuous coating of substantially constant thickness is provided.
  • the membrane wall is designed for a waste incinerator.
  • the membrane wall serves as sideway limit of the fire space, wherein a temperature in the range of e.g. 700-800°C can prevail.
  • the membrane wall is cooled by the steam running through the vertical upward extending steam pipes.
  • the membrane wall can however also be provided for other incinerators and possibly be cooled by another fluid flowing through the pipes, e.g. water.
  • the membrane wall can be provided as separator wall or as bulk head (at one or both sides exposed to the fire).
  • the same RVS-composition is used for both the coat-welding and the connection strip, having a high corrosion and abrasive strength in relation with the environment within the incinerator.
  • RVS welding material to weld the connection strip to the steam pipe, preferably with a composition substantially equal to that of the RVS applied in the coat-welded clad layer or the connection strip.
  • the coat-welding of the RVS clad layer and/or the attachment of the connection strip to the steam pipe by welding is preferably carried out in a protective environment, e.g. below a powder cover, to avoid environmental attack of the welding material or surrouding steel. This way of protection is known as such and needs therefor no further elaboration.
  • RVS strip The importance of a completely RVS strip is a.o. that therewith one can avoid that during fixing of the steam pipe to the connection strip by welding the carbon contents within the weld seal becomes to high due to diffusion of carbon from the surrouding steel.
  • RVS types contain Fe, C and alloy components and also Ni and Cr.
  • connection strip has a width of about 30 mm at the most. If the width is to large, the connection strip wil overheat and early collapse.
  • connection strip must suffice a predetermined straightness and the surface of the RVS welded onto the steam pipe must suffice a predetermined smoothness and layer thickness.
  • Said straightness is preferably within the following range:....
  • Said smoothness is preferably within the following range:...
  • the layer thickness is preferably between 1.8 and 2.5 mm.
  • the drawing shows in fig. 1 a part of a membrane wall 1 in perspective. It is made of mutual parallel extending steam pipes 2 of carbon steel, all around coated by clad-welding of RVS. Slod RVS connection strips 3 are welded to the mutually spaced steam pipers 2.
  • the weld connections are refered 4 (four in steam pipe longitudinal direction extending weld connections for each connecting strip 3 between two steam pipes).
  • Fig. 2 shows a steam pipe 2 in detail, showing the helical extending weld bead 5 of the clad-welded RVS coating.
  • the clad-welded coating provides a continuous smooth layer.
  • connection strip 3 contains a core of carbon steel.
  • the strip 3 is made of a composition according to Inconel 625 or 629 or others from the 600- or 700-series. This is also true for the coating or weld connection.
  • the coating of weld connection or strip contains iron (Fe) less than 10 wt%, preferably less than about 7.5 wt%, more preferably less than about 5.5 wt%, such as less than about 7 wt% or about 5 wt%.
  • the weld rod used for welding contains preferably Fe less than 3 wt%, e.g. less than about 1.5 wt%, such as less than about 1
