Abstract (en)
[origin: EP0699867A2] The burner has at least fuel and air supplies to a mixing zone (15), in which a spinning motion or vortex is generated in part of the combustion air. It has a tube (22) for stabilising the vortex, and a hollow lance (23) for supplying the fuel gas, and which is arranged substantially in the centre. The ID of the stabiliser tube is at least twice the OD of the lance, and the lance has at least one region (26,27) inside the stabilising tube for the lateral discharge of gas. The lance may also have at least two axially separated discharge regions, of which one may be inside the stabiliser tube, and one may be outside.
