Abstract
A burner for burning gaseous and/or liquid fuels in a combustion space (5), through the face (3) of which an oil lance (12) and/or several gas lances (13 and 14) extend. The oil lance and at least some of the gas lances are surrounded by an air pipe (4) that supplies primary air with its outer surface demarcating a flue-gas recirculation channel that opens toward the combustion space and surrounded by a source of secondary air. The air pipe and the source of secondary air extend into the combustion space. The air pipe is surrounded inside the combustion space by a baffle (20) that is axially separated from the face of the combustion space. Some of the gas lances surround the air pipe and are mounted on a sector with a diameter that is shorter than the longest diameter of the baffle.
