Definitions

  • the invention relates to an oxygen lance according to the Features of the preamble of claim 1 and a method of operating the same in a high temperature reactor.
  • Oxygenation to the gasification bed for example in a high temperature reactor, with the help of oxygen lances to realize.
  • Oxygen lances in the the senses referred to here are water-cooled nozzles, with which usually oxygen or oxygen enriched Air in the internal combustion chamber of gasification reactors is injected.
  • German patent 195 12 249 C2 teaches oxygen lances to use with at least one permanently burning pilot flame with high flame temperature and high burning speed operated in this way be that the lance oxygen at least approximately Speed of sound is accelerated whereby the lance oxygen is also extremely heated becomes.
  • the high temperature of the oxygen increases the gasification rate, the strong acceleration of oxygen increases the area of influence the lance is crucial.
  • an oxygen lance is used for this used with a burner for generation the pilot flame is equipped.
  • This burner / oxygen lance combination stands out in particular from the fact that in addition to a first oxygen channel, the for the entry of oxygen in the Gasification bed of the reactor, a separate, second oxygen channel is provided, the supply the pilot flame generated by the burner concerned with oxygen.
  • the object of the present invention is to provide a burner / oxygen lance combination as well as a procedure to indicate their use, in burner operation can be used while doing the appraisal the prior art dangers mentioned above and disadvantages.
  • the channel for transporting reaction oxygen that is, the oxygen that is required to react Gasification bed of the reactor is introduced, identical is with the channel for supplying fuel oxygen, i.e. the oxygen to supply the burner or pilot flame, is particularly advantageous achieved that regardless of whether the burner / oxygen lance combination with always burning Pilot flame with or without oxygen supply the gasification bed of the reactor is always driven an oxygen flow is led through the oxygen channel is because at least the burner flame with the stoichiometric combustion necessary amount of Oxygen (fuel oxygen) is supplied.
  • fuel oxygen i.e. the oxygen to supply the burner or pilot flame
  • the device-like structure of the oxygen lance simplified overall with burner device, because connections and additional channels for the separate inflow of oxygen for pilot / burner flame on the one hand and the oxygen supply to the gasification bed of the reactor on the other hand.
  • a control device which is the amount of oxygen supplied in at least controls two different pass states, becomes burner flame for the two operating states and supplying reaction oxygen to the gasification bed on the one hand and burner flame without feed of reaction oxygen in the gasification bed on the other hand the amount of oxygen required in each case dosed fed.
  • Fuel in the sense of this entire application such as methane gas, in-process synthesis gas or individual Components of the same as well as liquid and / or pumpable, pollutant-containing substances his.
  • An advantageous embodiment for a control device which is the amount of oxygen supplied in at least two different pass states controls, is the realization as in the oxygen flow valves connected in parallel. hereby becomes a robust and technically particularly simple Path to the establishment of the required forward conditions with precisely adjustable and kept constant Passage reached.
  • Another development of the invention provides the reactor end of the burner / oxygen lance combination with a replaceable one To provide the burner head.
  • this is advantageous because the burner head of the hot atmosphere the high temperature reactor is exposed and thus as a wearing part only for a limited service life features, so that a quick and easy interchangeability the maintenance of the oxygen lance clearly simplified.
  • the interchangeability of such a burner head especially through the Property of the invention favors that by the saving of supply channels of the invention constructive construction of the oxygen lance on the reactor side final burner head and the connection between burner head and oxygen lance in their structure is significantly simplified. So he can Burner head through a plug or screw connection be realized, which in spatial agreement with the channels of the oxygen lance stands.
  • An advantageous development of the method for Operating the oxygen lance provides for the control device between the two operating states to switch pulsating. That way that through the oxygen lance into the gasification bed of the reactor entered reaction oxygen pulsating entered so that there is the advantage that channels in the gasification bed which are from the oxygen jet the lance may have been formed in the pulse breaks break down. Thus "bridging" avoided in the gasification bed.
  • Fig. 1 shows a schematic representation of an oxygen lance for high temperature gasification more heterogeneous Waste according to the state of the art (A) and as an exemplary embodiment of the present invention (B) in Juxtaposition.
  • B is the fuel supply channel I inside. It surrounds him a single oxygen channel II, to which the separate feed channels known from the prior art for fuel oxygen and reaction oxygen are summarized.
  • the burner / oxygen lance combination B only used in burner operation without oxygen as a reactant in the combustion bed of the reactor should be introduced, so the fuel channel I and the oxygen channel II each so much Fuel or oxygen, as for stoichiometric Burning in the pilot flame of the burner is needed, the pressure of oxygen for the burner is selected so that it is always above the partial pressure in the high temperature reactor, so that hot syngas enters the Oxygenation is excluded. Should be additional Oxygen as reactive oxygen in the Combustion bed of the reactor get, so will more oxygen is supplied in oxygen channel II.
  • the feed is from that in this figure Control device not shown provided.
  • Fig. 2 shows a longitudinal section through a more detailed Embodiment of an inventive Burner / oxygen lance combination.
  • the channel for supplying fuel gas I and the channel to supply oxygen II, which is the channel for Fuel surrounds, so that pipes inside each other arise. This becomes particularly clear in the cross section shown along the right Axis A-A.
  • connection valves which are separate here to the control valves and the flow connection between the valves and the feed channels shown.
  • water cooling system consisting of a supply nozzle 11 and feed-through channels 4 and 5 such that the water along the main axis of the oxygen lance first of all along the lance tube to the tip of the burner 1 inserted and then from the burner tip 1 in the opposite direction.
  • the burner tip 1 is through a plug connection attached to the lance tube 2 and has a funnel-shaped Sinking on which is from the reactor side End of the burner tip to the lower one Mouth of the feed pipe for fuel I tapered.
  • the burner tip is designed so that the cooling water channel that separates the water from the Spends reactor side facing the burner tip is connected in terms of flow to the cooling water channel, which the water in the opposite direction leads. This is achieved through an appropriate design the burner tip through small, with the cooling water channels tightly fitting when plugged in Channels with channel walls 31, 32.
  • Fig. 3 shows an embodiment for an inventive Control device, which by two in Valves IV and V connected in parallel with oxygen flow is realized and also a valve VI for control the separate fuel supply.
  • the oxygen flows into the left distributor and divides into a first and a second stream of oxygen.
  • the first flow of oxygen is in its flow rate from the valve controlled for the fuel oxygen V during the second flow of oxygen in its quantity through the valve is determined for the reaction oxygen IV. After passing the valves, they unite two oxygen flows back to a current that then exits the control device. It can by closing valve IV and that accordingly wide openings of the valve V the oxygen in of the amount to be dosed as for stoichiometric Burning in the pilot flame of the burner is required is, this pressure always above the partial pressure must be in the high temperature reactor. to Preservation of the stoichiometric combustion ratio must therefore open the valve VI, which Supply of fuel gas controls, set accordingly become.
  • Opening valve IV Additional oxygen, which is related to the Combustion in the pilot flame in superstoichiometric Amount supplied and thus as a reactant in the Gasification bed of the reactor should get through Opening valve IV can be added.
  • the pulsating Switch between the aforementioned first operating mode ("burner only”) and the second operating mode ("Burner and reaction oxygen supply”) can by pulsating opening and closing of the valve IV can be realized in the simplest way.
