Definitions

  • the invention relates to a method for starting a gasifier for gasifying carbon-containing fuel with the aid of oxygen-containing gasifying agent in the fluidized bed.
  • HTW high temperature Winkler
  • the gasifier is heated without pressure to a temperature with normal gas burners, so-called bakeout burners, which corresponds at least to the later gasification temperature, for example between 800 and 1000 ° C. Reaching the heating temperature is determined by measuring the head of the carburetor.
  • the heating burners are dismantled while hot, while at the same time all supply of inert gas is switched off. At the points where the heating torches have been dismantled, the openings are then closed with blind covers. Because of the possibility of backflow of hot gases, the removal of the heating burner from the heated carburetor is only possible with great safety precautions.
  • the carburetor is flushed again with inert gas in order to expel oxygen-containing gases which may have penetrated into the carburetor when the heating burner was removed.
  • the new inert gas feed is still depressurized, but it is disadvantageous because the carburetor inevitably cools down.
  • the residual temperature of about 500 to 600 ° C is sufficient, however, to ignite pilot fuel, for example lignite coke, which is subsequently introduced into the gasifier and to start the gasification process while gradually adding oxygen-containing gasifying agent.
  • this object is achieved in that the carburetor is filled with an inert, gaseous medium and brought under an overpressure and, after determining the tightness, a combustible gas mixture in a combustion chamber connected to the lower part of the carburetor with the aid of an ignition device which works under pressure ignited and essentially burned while maintaining the excess pressure at least until the temperature inside the gasifier corresponds to the gasification temperature.
  • the implementation of the method is therefore dependent on the presence of an ignition device that works under pressure and is known, for example, from DE-PS 28 32 115 by the applicant.
  • the known ignition device is arranged according to the invention on a combustion chamber which is provided on the lower part of the carburetor and is used to mix an ignitable mixture z. B. to burn air and fuel gas. Since both the igniting of this combustible mixture and its combustion can take place under pressure, it is possible to initiate the combustion after inerting and the leak test of the carburetor without having to reduce the pressure in between. This ensures that further leaks can no longer occur due to the dismantling of parts, for example the known heating burners, and / or due to the interim lowering of the pressure on the carburetor.
  • the hot combustion gases generated in the combustion chamber are suitable for gradually heating the larger quantities of fuel within the carburettor to the ignition temperature in a reducing atmosphere and thus initiating final gasification reactions.
  • the gasifier is gradually supplied with an oxygen-containing gasifying agent. In this way, the carburetor is brought to performance in a relatively short time and with great operational reliability.
  • the amount of gas mixture burned in the combustion chamber is reduced.
  • the combustion in the combustion chamber can even be switched off completely. Since the ignition flame can be generated again using the ignition device, which can be switched on at any time, it is possible to switch the combustion on again if the gasification operation should be interrupted for a while.
  • a device for starting a gasifier for gasifying carbon-containing fuel with the aid of oxygen-containing gasifying agent in the fluidized bed under pressure is proposed, which is characterized in that a pressure-resistant combustion chamber for the combustion of a combustible gas mixture with a pressure-functioning ignition device with the lower one Part of the carburetor is at least temporarily connected.
  • the combustion chamber can be connected in two ways to the gasification chamber of the gasifier by means of an openable slide.
  • the combustion chamber is advantageously arranged at an acute angle to the longitudinal axis of the carburetor, because this inclination of the combustion chamber facilitates restarting.
  • the inclination of the combustion chamber is namely sure that fuel that has entered the combustion chamber from the fluidized bed and is intended for gasification can flow out of the combustion chamber again and again under the effect of gravity. If gravity alone is insufficient, the remainder is eliminated by the flow of the combustion gases that burn in the combustion chamber.
  • the figure shows the diagram of a carburetor in section.
  • the carburetor 1 is used to convert fuel 2, which is introduced into the lower part 4 of the carburetor 1 via an entry device 3 and there with the aid of oxygen-containing gasifying agent 5, which is fed to the carburetor 1 via a plurality of nozzles (not shown) Gas is implemented.
  • the conversion of the fuel 2 with the aid of the gasification agent 5 takes place within a fluidized bed 6.
  • temperatures between 800 and 1000 ° C. and pressures between 5 and 30 bar prevail within the gasifier 1.
  • a discharge 8 At the head 7 of the carburetor 1 there is the discharge 8, in the path of which a slide 9 is arranged, by means of which the gasification pressure inside the carburetor 1 can be set.
  • a discharge member 10 At the lower end of the lower part 4 of the carburetor 1, a discharge member 10 is provided, via which the non-convertible components 11 of the fuel 2 are drawn off.
  • a combustion chamber 13 is connected, which with the Carburetor 1 is permanently connected and is optionally separated from the carburetor 1 by a lockable slide 14.
  • a combustible gas mixture 15 is burned, which consists for example of natural gas, product gas or a mixture of CO / H2.
  • the combustion takes place under pressure with the help of oxygen 16 or air, and by adjusting the proportions between the gases 15 and 16 it is ensured that only a partial combustion of the fuel gas 15 can take place and an excess of oxygen is avoided.
  • the combustion in the connected combustion chamber 13 takes place continuously and the occurrence of explosive gas mixtures is thereby excluded.
  • An ignition device 17 such as is described in detail in DE-PS 28 32 115, is used to ignite the combustion within the combustion chamber 13. With the help of this ignition device 17 it is possible to keep the combustion in the combustion chamber 13 under pressure and to start it up again at any time.
  • the carburetor 1 For example 2000 m3 / h of fuel gas 15 are burned with 200 m3 / h of oxygen 16, ie in a ratio of 10: 1, in the combustion chamber 13.
  • the supply of carbon-containing fuel 2 and the gradually increased addition of oxygen-containing gasifying agent 5, for example air, steam or O2 takes place until the gasification is in progress.
  • the combustion chamber 13 is either separated from the effective area of the carburetor 1 via the lockable slide 14 or, when the connection 14 is open, an ignition flame 18 can be maintained on the ignition device 17 while the supply of combustible gas 15 and oxygen 16 is switched off.
  • a gas mixture is used which is characterized by a lack of oxygen and is therefore not explosive.
  • this fuel gas is burned, an unburned excess remains, which can be discharged at the outlet 8 of the gasifier 1 into a heating gas system or power plant (not shown) and can be completely burned there.
