Definitions

  • the present invention relates to a method for igniting a gasification reactor operated under increased pressure and producing a partial oxidation gas consisting essentially of carbon monoxide and hydrogen following an interruption in operation by means of a pilot burner provided with a high-voltage ignition device and a flame monitor.
  • a burner of the type mentioned above is described for example in EP-A 0 363 787. This burner can be used both as a support burner and as a normal gasification or service burner for the production of CO and H2-rich gases by partial oxidation in a pressurized reactor.
  • gasification reactors operating at elevated pressure are first relaxed after a failure or an operational shutdown by reducing the pressure and then flushed and evacuated several times with intergas. This is to remove partial oxidation gas residues, prevent the formation of an explosive residual gas atmosphere and form a sufficiently inert atmosphere in the gasification reactor, to enable a safe re-ignition after each flame extinguishes.
  • this process takes a long time and the inert purge gas must be kept available on the system at all times.
  • the temperature of the wash water is around 120 ° C, which corresponds to a saturated steam pressure of approx. 2 bar. When relaxing, this pressure can only be fallen below if the wash water has been cooled accordingly beforehand.
  • the invention is therefore based on the object To provide a method for igniting a gasification reactor which avoids the disadvantages described above.
  • the method of the type mentioned at the outset which is used to achieve this object is characterized in that the ignition process takes place in the gasification reactor which is not inertized and is under gasification pressure, the pilot burner having a defined ignition process from an upstream container for an ignition process which takes place without damage to the gasification reactor by means of explosions sufficient quantity of oxidizing agent is supplied, the quantity ratio of which to the fuel is adjusted so that the flame in the pilot burner is operated with a deficit of oxidizing agent, the ignition process being monitored by the flame monitor and, after the successful expiration thereof, the supply of further oxidizing agent for the normal operation of the gasification reactor is released.
  • the characteristic of the process according to the invention is that it does not relieve the gasification reactor or purge it with inert gas.
  • the gasification reactor is thus still under an increased pressure during the ignition process, which corresponds to or slightly below the gasification pressure.
  • Via the upstream container only an amount of oxidizing agent is supplied to the gasification reactor during the ignition process in such a way that the ignition process can take place without damage to the gasification reactor due to explosions.
  • the gasification reactor is initially switched off from further supply of oxidizing agent. Only when the ignition process, which is monitored with the help of a flame monitor, has been successful the supply of further oxidizing agent is released to the extent required for the normal operation of the pilot burners of the gasification reactor. From this point on, the conditions for resuming production of the gasification reactor are met.
  • the ignition device, pilot burner and flame monitor can be attached to the gasification reactor in a spatially separated manner. According to another arrangement, it is also possible to combine the ignition device and the flame monitor with the pilot burner to form one structural unit. According to a preferred embodiment, the ignition device, pilot burner and flame monitor can finally be integrated in one or more gasification burners of the gasification reactor.
  • the ignition device 1 is arranged in the gasification reactor 6. If necessary, it can be withdrawn into the lock 7 to protect it during normal gasification operation. As a result, it is also possible, if necessary, to repair or replace the ignition device 1 without having to relax the gasification reactor 6.
  • the flame monitor 2 and the pilot burner 8 are also arranged in the gasification reactor 61. In deviation from the schematic representation in the figure, these system parts can of course be integrated into structural units in the manner described above.
  • ignition sparks are generated in a manner known per se by high-voltage discharge.
  • the line 13 is used to supply current to the ignition device 1.
  • the lock 7 is covered by the line 14 in which the valve 15 is provided, and the relaxation takes place via the line 27 in which the valve 28 is provided.
  • the oxidizing agent required for the ignition process preferably air or air enriched with oxygen, is located in the container 3 upstream of the pilot burner 8.
  • the amount of oxidizing agent located there is dimensioned according to the invention so that it is sufficient for an ignition process taking place without damage to the gasification reactor 6 due to explosions.
