Abstract

1,155,296. Pulverized fuel burner. BABCOCK & WILCOX CO. 13 Oct., 1966 [13 Oct., 1965], No. 45836/66. Heading F4T. A pulverized fuel burner comprises a burner head 5, situated in the throat 4 of a firing port 1 in a furnace wall 2, to which a pulverized coal and primary air mixture is supplied through a pipe 6, and which is surrounded by an annular stream of secondary air supplied by a cylindrical vaned air register 10, the burner also including a baffle arrangement 11 supported on a pipe 12 within pipe 6, an inner vane of said arrangement being apertured to direct a small proportion of the coal/air mixture to an axial region downstream of the burner where it may be viewed during ignition by radiation sensitive means 13 arranged in tube 12. The radiation sensitive means 13 are connected in an electrical circuit of a flame monitoring system. Air is passed down tube 12 to cool means 13 and assist combustion of the axial portion of the coal/air mixture. The baffle arrangement comprises three frusto-conical vanes which are concentric and diverge away from the burner head 5, and have successively smaller inner diameters. The apertures in the inner vanes may be circular or arcuate slits.
