METHOD AND DEVICE FOR STARTING UP GASIFYING REACTORS OPERATED WITH COMBUSTIBLE DUST

摘要

The invention relates to a method for starting up a gasifying reactor comprising a plurality of burners.  In this case, each burner is charged via a dense-stream delivery line (51, 52, 53, 54) assigned to it with combustible dust from a metering vessel (1) and charged via a gas delivery line (62, 63) with combustible gas, wherein a fuel mixture of combustible dust and combustible gas is provided before a point in time at which a burner is ignited, wherein a first composition of combustible dust and combustible gas with which a first burner is charged for ignition is controlled in dependence on the amount of fuel fed to the second burner for ignition, said second burner being charged with a second composition of combustible dust and combustible gas for ignition, after the ignition of a second burner following the ignition of the first burner, and so the starting up of each of the plurality of burners of the gasifying reactor takes place with a controlled supply of the fuel load.  The invention also relates to a gasifying reactor (7) for carrying out the method according to the invention.
