Abstract (en)
[origin: EP0619458A1] To provide a rotary furnace burner using solid fuels such as finely granulated coal dust, having a coal dust annular-gap nozzle (12) which is wear-resistant and guarantees a long service life of the burner, it is proposed according to the invention that the solid-fuel duct (10) has in the region of its annular-gap nozzle (12) which lets out the solid-fuel/transporting-air suspension, on at least one of the boundary walls of the annular-gap nozzle, a wear protection consisting of an inherently rigid sleeve-like ceramic body (21) which is detachably and exchangably fixed on a metallic carrying body (22) via an interposed flexible ceramic-fibre layer (23).
