Abstract

A burner 10 for a micromix combustor has a flow of oxidant along an axial passage 20, and at least one injector 50 arranged to feed at least one of a gaseous oxidant or a gaseous hydrogen fuel into the oxidant flow. The injector feed is in a direction 60 transverse to, and radially offset 70 with respect to the burner passage axis 30. The burner arrangement may include several injectors, spaced around a circumferential wall 25 of the burner, and where four injectors are use, two may feed oxidant and two may feed hydrogen. Injectors may also be arranged diametrically opposite relative to the burner axis, and the axial passage may include a swirler (100 Fig 2). The burners may be used in a micromix combustor (Fig 5A, 5B), and the burners may be arranged in at least one, but preferably several concentric rings (120, 121, 122, Fig 5B) with injectors being serviced by a manifold arrangement (130, 140, Fig 5B).
