With a slag runner on burners or burner niches for protection against dripping slag, which occurs during the gasification of fine-particle fuels that contain ash, within a gasifier, reliable protection of the burner exits or the burner niches to prevent them from becoming clogged with slag is supposed to be made available. This is achieved in that the slag runner (8) is formed by a plurality of pipe elbows (9) through which cooling medium flows, which elbows, in the installed position, form a runner surface that faces into the interior of the gasifier, stands at a slant relative to the gasifier wall (1), and shields the burner (2) or the burner niche (7) at the upper region, in the direction of gravity, which surface configures an essentially acute angle (α) relative to the burner wall (1). |
