초록 ▼

A burner for the combustion of fine-grained to dusty solid fuels incorporates a central internal tube for supplying the solid fuels and an annular gap surrounding the internal tube and delimited by a cooled external tube, for supplying oxygen or oxygen-containing gas. The annular gap ends externally by an exhaust port directed obliquely relative to the longitudinal axis of the burner and peripherally surrounding the end of the central internal tube, or by a plurality of exhaust ports annularly disposed about the longitudinal axis of the burner. In order to ensure the complete combustion of the fine-grained to dusty fuels at a long service life of the burner, the inclination of the exhaust port(s) relative to the longitudinal axis of the burner is below 20°. The exhaust port(s) is/are arranged transverse to the longitudinal axis of the burner and in the radial direction relative to the same at a distance of between 5 and 30 mm from the inner wall of the internal tube. The inclination of the exhaust port(s) relative to the longitudinal axis of the burner and the radial distance of the exhaust port(s) relative to the inner wall of the central internal tube are coordinated in a manner that the intersection of the extensions of the exhaust port and of the inner wall of the internal tube outside of the burner lies 20 to 80 mm in front of the burner mouth.
