There is described a reactor for entrained flow gasification for operation with dust-type or liquid fuels, wherein a number of gasification burners are disposed away from the reactor axis, with the center line of a gasification burner having an oblique position that is other than parallel to the reactor axis, it being possible for said oblique position to extend at different angles up to an angle of 90°. The center line does not necessarily have to intersect the reactor axis; rather the center line can pass the reactor axis at a predetermined distance. This arrangement is associated with a significant reduction in the unwanted discharge of dust-type fine slag, which is difficult to utilize, in conjunction with the possibility of reducing the reactor diameter due to its structure.
