Abstract

1,026,263. Burners. FOSTER WHEELER Ltd. Dec. 20, 1963 [Dec. 21, 19621, No. 50443/63. Heading F4T. Air is supplied to a burner burning liquid, gaseous or pulverized fuel by an annular passage 20 surrounding the burner nozzle 24 and having a circumferential inlet 56 for air and a discharge opening 58 for the fuel/air mixture, the ratio of the flow area of the air inlet 56 to the flow area of the discharge opening 68 being between 0À9: 1 and 1À8 : 1. The annular air passage 20 is formed by a flared baffle 46 and a washer-shaped plate 52 secured to the burner nozzle. Alternatively, the air passage may be defined by a pair of concentric baffles as shown in Specification 860,057. The air inlet 56 is radially directed towards the burner axis and may be provided with interconnected vanes 60 rotated by a hand wheel 66. The burner shown burns pulverized fuel supplied in a fuel/air mixture by a pipe 32 to a volute section 30 leading to the tapered annular space 38 between an outer casing 34 and an inner sleeve 36 of the nozzle. Ribs are provided on the casing and sleeve to rotate the mixture. An igniter 42 and an electrode tube 44 extend through the sleeve. In a modification, Fig. 4 (not shown), the unit comprising the flared baffle and the washershaped plate is secured to four rods extending to hand wheels at the front of the burner and by adjusting the hand wheels the unit can be tilted about a point in or in front of the nozzle outlet. The shaft for rotating the vanes in the air entrance to the unit is provided with a universal joint.
