Definitions

  • the invention relates to a method for combustion of combustible material comprising carbonacious fuel and plastic material with an oxygen containing gas and also a moderator gas.
  • the invention also relates to a burner for preforming the method comprising a central channel and outlet for supplying a solid combustible material to the combustion zone and at least one first substantially annular channel disposed coaxially with said central channel and having an outlet to supply an oxidant gas flow to the combustion zone.
  • a second annular channel is provided disposed coaxially with said central channel and located outside said first annular channel, the central channel being connected to a supply of finely divided solid plastic material and the second annular channel being connected to a supply of carbonaceous fuel.
  • the transport problems can be overcome. Moreover it provides the possibility to introduce the different fuels at different temperatures thereby increasing this efficiency of the combustion.
  • EP-A 108425 there is disclosed a burner comprising a central channel and outlet for fuel, an annular channel disposes coaxially with said central channel for supplying fuel and intermediate supply means for an oxidant gas.
  • the burner according to the invention is different from this known burner as it does not possess three coaxial annular supplies for fuel, oxidant and fuel because the oxidant gas is supplied by a number of separate circular outlets.
  • the invention is basicly different from this known burner in that the two fuel channels are connected to the same supply of carbonaceous fuel.
  • a third annular channel is disposed coaxially between said central channel and said second annular channel and said third channel is connected with a supply of moderator gas.
  • the burner 10 has a central channel 11 with a circular cross-section disposed along a longitudinal axis 12 and having a discharge outlet 13 for supplying a finely divided solid fuel such as waste plastic, pulverized coal, mixed combustible waste material etc. to a combustion zone 15.
  • the channel 11 is limited by an annular wall 14. Parallel to the axis 12 and concentrically surrounding the annular wall 14 there is provided an annular wall 16.
  • the annular walls 14 and 16 together define an annular channel 17 having a discharge outlet 18 for supplying a moderator gas to the combustion zone 15.
  • moderator gas can be used steam, carbon dioxide or nitrogen or a mixture thereof.
  • annular wall 20 Concentrically arranged around the wall 16 is an annular wall 20, defining together with the annular wall 16 an annular channel 21.
  • the annular channel 21 has an outlet 22 for supplying an oxidant gas to the combustion zone 15.
  • the oxidant gas will be oxygen-containing gas, or optionally a mixture of oxygen-containing gas with a moderator gas such as e.g. steam or carbon dioxide.
  • the channels 11, 17 and 21 all have annular cross-sections, the surface of which gradually decreases as seen in the desertion of the combustion zone. In this way a speed increase towards the outlets will be the result.
  • a hollow wall number 25 Concentrically around the wall 20 there is arranged a hollow wall number 25, which defines together with the wall 20 an annular channel 26 having an outlet 27 for supplying a liquid fuel such as oil into the combustion zone 15.
  • the outer part of the wall 20 is near the outlet inclined so as to intersect the central axis 10 at a distance from the outlet 13.
  • the inner part of the wall number 25 is inclined in 00 as to form a part which is parallel thereto.
  • the hollow wall member 25 consists of an inner wall 30 and an outer wall 31 connected near the outlet by a frontwall portion 32.
  • the inner well 30 is substantially parallel to the wall 20 and firms one wall of the channel 26.
  • the front wall portion 32 is from the outer wall 31 curved gradually inwardly and is flushed with the outlet side wall of the burner 10, at the place when it is connected to the innerwall 30.
  • a dividing wall 34 is provided which extends to nearly to the frontwall portion 32 and is curved in accordance therewith.
  • two channels 36 and 37 are formed interconnected near the front wall position 32 by a passage 38 for a coolant liquid.
