METHOD AND DEVICE FOR IGNITING AND OPERATING BURNERS WHEN GASIFYING CARBON-CONTAINING FUELS

With a method and a device for igniting and operating burners when gasifying a carbon-containing fuel using at least two gasification burners, start of the pressure gasification with short start times is made possible, at high pressures, without prior inertization of the gas space, while avoiding co...

Beschreibung
Zusammenfassung:	With a method and a device for igniting and operating burners when gasifying a carbon-containing fuel using at least two gasification burners, start of the pressure gasification with short start times is made possible, at high pressures, without prior inertization of the gas space, while avoiding continuous fuel gas consumption in the pilot burner or ignition burner and also protecting stationary ignition burners against contamination by configuring one gasification burner as a start-up burner, which is ignited by at least one pilot burner using an electrical ignition device. A combustible gas mixture including a fuel gas and oxygen-containing gas is ignited by the pilot burner, in the start-up burner. After ignition of the start-up burner, at least one further gasification burner is ignited by this burner. The start-up burner is operated further as one of the gasification burners of the carbon-containing fuel via a change in medium.
