Abstract (en)
[origin: US4457695A] A burner (1,29) for the combustion of powdery fuels, in particular coal-dust, comprises a central duct (9,37) to supply a jet of core-air (13,41), a fuel channel (12,40) to supply the fuel and a casing channel (5,6; 31) to supply secondary air (7,8; 36). In order to make such a burner (1,29) also suitable for lesser power ranges, a widened range of regulation and less sensitive to a wide coal-dust band, the discharge means of the fuel channel (12,40) is designed as an annular nozzle (23,53) of which at least one of the two circumferential walls (19,47) is rotatable and driven, and the discharge means of the central duct (13,41) being so designed that the jet of core-air (13,41) is directed at least in part outwardly against the discharging fuel for the purpose of deflection into the region of the secondary air (7,8; 36).
