Burner with adjustable radial fuel profile

Abstract

A burner (1) with a longitudinal burner axis (2) and a mixing channel (3, 4), formed in an annular manner around the longitudinal burner axis (2), for the mixing of fuel and air. Each mixing channel is bounded radially on the inside by a channel hub (5, 6) and radially on the outside by a channel outer wall (7, 8). A fuel concentration distribution in the mixing channel (3, 4) from the channel hub (5, 6) to the channel outer wall (7, 8) being adjustable by adjusting the introduction of fuel to provide an adjustable fuel concentration distribution at respective radial locations across each mixing claimed. Also a combustion system (20) with a burner (1) and to a method for operating a burner (1).

Dependencies are inferred from the claim text.
