Abstract (en)

[origin: EP0930462A2] The mixer (8) through which primary air (11) flows is positioned after the burner jet (2), and secondary air flows axially through the outer periphery. A fire pipe (16) is enclosed by a pipe element (27) to form an annular chamber (26) open on the burner side, and conveys and discharges extra secondary air via passages (17) into the fire pipe. The annular chamber has a sleeve-shaped partition (30) joined to the bottom, to form an outer annular chamber (32) and inner annular compartment (31), to feed secondary air via passages (12) into the fire pipe.
