Abstract

377,474. Pulverulent-fuel burners. ATELIERS, J. HANREZ SOC. ANON., Monceau-sur-Sambre, Belgium. Aug. 29, 1931, No. 24346. Convention date, Dec. 17, 1930. [Class 75 (i).] The mixture of powdered fuel and air is delivered by a bend 5 to a nozzle piece 7 containing a venturi choke tube 14 arranged between two sets of oppositely inclined helical vanes 12, 13. The bend 5 is secured to a spiral casing 1 terminating in a cone 10 which carries an annular support 8 surrounding the discharge end of the nozzle-piece 7. Secondary air is supplied to the casing 1 and its whirling movement is increased on discharge by helical vanes 9 provided in the cone 10. Additional air may be supplied to the flame through a tube 15 which projects centrally through the nozzle-piece 7 and is fitted with a valve 17. The nozzle-piece 7 and tube 15 may be adjusted relatively to the casing 1 by means of bolts 18 and nuts 20 engaging lugs 19 on the bend 5.
