Definitions

  • the invention relates to a device for assembling and disassembling Canned tube registers in the combustion chamber of an olefin plant cracking furnace, each Canned tube register has vertical canned tubes and several canned tube registers in the assembled condition in the combustion chamber in at least one row next to each other are arranged and the firebox end walls, a firebox floor and a Has firebox ceiling.
  • the cracking furnace is used to split saturated hydrocarbons such as naphtha or ethane and is therefore a very important component in petrochemical plants.
  • the can Because of their high thermal load, the can has only one limited lifespan of around 3-5 years.
  • the canned tubes are serpentine complex structures made of a very expensive Material that can only be welded by special specialists.
  • the in and out Exits and the suspension of the cannula penetrate the firebox ceiling.
  • the exits are the shortest way with vertically arranged heat exchangers connected, so-called fission gas coolers. This cracked gas cooler and the connecting Pipelines largely fill the space above the firebox ceiling.
  • the worn canned tubes were either in individual parts disassembled and via entrance doors or dismantled end wall panels from the Firebox removed or they were in larger registers over the firebox ceiling away.
  • the installation of new canned pipes ran accordingly.
  • H. either Placement of individual parts via the Feuerraurn entrance doors with extensive Welding work in the furnace or introduction of larger registers through the Firebox ceiling with less welding work.
  • the object of the invention is therefore a device for assembling and disassembling Propose canned tube registers that avoid these disadvantages.
  • the assembly time can be reduced to half the previous time.
  • the dummy sleeves are the Fire chamber ceiling with plugs made of insulating material and lids closable.
  • the vertical slots can be insulated with the combustion chamber side Sheet metal elements can be made lockable. This leads to another Simplification of assembly.
  • the vertical slots can run continuously from the ceiling to the bottom of the Range. Damage to the front wall or the canned tube register this is largely avoided when inserting or removing the register.
  • the figure shows a side view of the device according to the invention for assembly and disassembly of canned tube registers 1 in the combustion chamber 2 of an olefin plant cracking furnace.
  • the canned tube registers 1 have vertical canned tubes 3.
  • In the assembled Condition are several canned tube registers 1 in the fire chamber 2 in at least one row installed next to each other, with the inlet and outlet pieces the firebox ceiling 4 penetrate; this is schematically summarized as a dash-dotted line 5 in the figure only hinted at.
  • an end wall 6 has at least one vertical slot extends from the firebox ceiling 4 to the firebox floor 7, opened.
  • the Firebox ceiling 4 is pierced by blind sleeves 8. Through the dummy sleeves 8 through trolley 9 with the help of winches 10 to the Firebox ceiling 4 raised so that they connect flush to the dummy sleeves 8 and by at least one register width from the vertical slot of the end wall 6 protrude.
  • the can 3 of the can register 1 to be (de) assembled in each case are fixed to each other and in a support frame 12 with clamping devices 11.
  • the support frame 12 is in turn via a lift system 13, which consists of hoists, Trolleys and reel bogies are suspended on the trolley track 9 and can be positioned horizontally and vertically via the lift system 13.
