Abstract
This invention relates to a burner () for burning a suspension of solid fuel in oxygen containing gas. A portion of the suspension is passed through a first conduit () which contains a bluff body () and helical vanes to impart turbulence and swirl to the suspension. A further portion of the suspension is passed through a second conduit () which is coaxial with the first conduit. Means for varying the relative sizes of each portion are provided. The arrangement allows improved fuel/air mixing, flame shape, heat transfer and control of NOx emissions.
