Claim:
1. A method for starting up a gasifying reactor that includes a plurality of burners, wherein each burner is charged with combustible dust from a metering vessel via a dense flow conveyor line, which is assigned thereto, and with combustible gas via a gas conveyor line, wherein a fuel mixture of combustible dust and combustible gas is provided prior to a moment of ignition of a burner, the method comprising: charging a first one of the burners with a first fuel load having a first composition, the first composition being based on a combustible dust flow and a combustible gas flow to ignite the first burner; charging a second one of the burners with a second fuel load having a second composition, the second composition being based on a combustible dust flow and a combustible gas flow to ignite the second burner after igniting the first one of the burners; and decreasing the fuel load to the first burner in response to igniting of the second burner to generate synthesis gas gradually by modifying the first composition to obtain a modified first composition, the modified first composition including a combustible dust flow and a combustible gas flow and being modified based on the second fuel load supplied to the second burner for ignition and in response to the ignition of the second burner, the modified first composition being different than the first composition, wherein the combustible gas flow in the first composition is reduced when the second burner is ignited.
