METHOD AND DEVICE FOR IGNITING AND FOR OPERATING OF BURNERS IN THE GASIFICATION OF FUELS THAT CONTAIN CARBON

With a method and a device for igniting and operating burners when gasifying a carbon-containing fuel using at least two gasifying burners, the aim is to make it possible for the pressure gasification to be started at high pressures with short starting times without the gas space first being rendered inert, while at the same time avoiding continuous consumption of the fuel gas in the pilot burner or ignition burner and also protecting the ignition burners from becoming soiled when they are inoperative. This is achieved in terms of the method by one of the gasifying burners being designed as a start-up burner, for the ignition of which there is at least one pilot burner, which is ignited by means of an electrical ignition device, wherein a combustible gas mixture comprising a fuel gas and a gas containing oxygen is ignited in the start-up burner by the pilot burner, wherein, after the start-up burner has been ignited, at least one further gasifying burner is ignited by said start-up burner and, by changing the medium, the start-up burner is then operated as one of the burners gasifying the carbon-containing fuel.
