Abstract

The burner has a secondary air tube (3) placed around the longitudinal axis (27) of the burner and closed by an end wall (38) at the end away from the burner mouth (2). The secondary air tube is enclosed by a primary mixer pipe (4) which introduces primary air or a mixture of gas and fuel and which has a flow stabilising area (49) placed upstream in the flow direction of the primary mixture. Secondary air (19) is brought in through an inlet housing (28) which encloses part of the primary mixer pipe and forms a radial channel (40) which is connected to the internal cross section of the secondary air tube through ducts (35) which cross the ring shaped cross section and feed secondary air from the channel into the secondary air pipe.
