Abstract
A burner is provided with a burner block having a recess formed in the back thereof for receiving a fuel atomiser and a plurality of oxygen inlets for creating a converging cone of oxygen for intersection with any fuel issuing from the atomiser. Such an arrangement also provides a protective wall for protecting the atomiser from the harsh environment to which the burner is exposed and simplifies the oxygen supply arrangements.
Claims12
An oxygen-fuel burner comprising:
- an outer jacket having a first inlet end, a second outlet end for combustion flame discharge, and a longitudinal axis X;
- fuel supply means for introducing a stream of fuel to a chamber;
- oxygen supply means for introducing an oxidant formed of one of air, oxygen, or both air and oxygen to the chamber;
- and
- a burner block for receiving said fuel and said oxidant and for directing said fuel and oxidant downstream thereof, and having rear and front surfaces the rear surface of the burner block including a recess in which is positioned a nozzle of a fuel atomiser;
- the front surface of the burner block including a central fuel outlet positioned at least near the longitudinal axis X and through which atomised fuel from said fuel atomiser is directed;
- said burner block further comprising a plurality of first oxygen outlets for supplying a first stream of oxygen to a position radially outward of said fuel stream, said first oxygen outlets being angled inwardly at an angle .theta. relative to longitudinal axis X thereby to create converging first streams of oxygen intersecting said longitudinal axis X and therefore atomised fuel from the central fuel outlet.
