Definitions

  • the present invention relates to fluidized bed apparatus, in particular to a so-called Circulating Fluidized Bed Apparatus (CFBA).
  • CFBA Circulating Fluidized Bed Apparatus
  • a CFBA typically comprises a fluidized bed apparatus, designed as a combustor, incineration reactor, boiler, gasifier, steam generator etc., hereinafter called fluidized bed combustor.
  • the combustor walls are made of tubes, through which water runs, wherein said tubes are either welded directly to each other to provide a wall structure or with fins/ribs between parallel running tube sections.
  • the separator serves to disengage the flue gases and solids. Thereafter the separated flue gases and solids are treated separately.
  • the solids are either directly returned into the combustor and/or may be fed into an after treatment apparatus such as an intermediate heat exchanger, in particular into at least one Fluidized Bed Heat Exchanger.
  • the general process engineering of this type of a fluidized bed combustor is more or less defined and includes:
  • the invention also suggests a method for replacing an outlet insert of a nozzle in a fluidized bed combustor in particular in an fluidized bed combustor according to the invention, comprising the following steps:
  • the outlet insert comprises a diverting element, with which the flow of the gaseous medium is diverted in two, three or more sub flows, wherein the main directions of the sub flows are inclined to each other.
  • the nozzle pipe is fixed to a wall of the fluidized bed combustor it is suggested that the nozzle pipe is arranged partly in an inner wall delimiting the reaction chamber, wherein the nozzle pipe protrudes into the reaction chamber and wherein the welded joint is arranged on a section of the nozzle pipe that extends into the reaction chamber.
  • the fluidized bed combustor comprises a reaction chamber 2 with a material inlet 1, through which particulate solid material can be introduced in the reaction chamber 2.
  • a fluidized bottom 3 is embodied, through which a primary gas is introduced into the reaction chamber 2.
  • the particulate material in the reaction chamber 2 is fluidized by the primary gas.
  • reaction gases produced in the reaction chamber 2 leave the reaction chamber through outlet 4, eventually comprising particulate material.
  • a separator Downstream of the outlet 4 a separator may be arranged for separating the reaction gases from the particulate material.
  • multiple nozzle may be arranged for providing secondary gaseous medium, such as secondary air into the fluidized particulate solid material.
  • the outlet insert 7 is inserted into the nozzle pipe 6, wherein the outlet insert 7 comprises a flange 9, which abuts against an end face of the nozzle pipe 6.
  • the outlet insert 7 can be easily exchanged by destroying the welded joint 8, so that afterwards the outlet insert 7 can be removed from the nozzle pipe 6. After inserting a new outlet insert 7, the new outlet insert 7 can be connected to the nozzle pipe 6 by welding.
