Abstract

A burner for introducing a suspension of solid fuel particles into a combustion chamber which includes a tubular conduit arranged to receive the suspension therethrough, and flow diverting means positioned at the discharge end of the conduit, and subdividing the cross section of the discharge end into a plurality of discharge openings. The burner may include a centrally disposed conduit which is coaxial with and surrounded by the tubular conduit, and an outer conduit surrounding the tubular conduit and coaxial therewith. The flow diverting means can be positioned at various positions between the respective conduits, to create a turbulent suspension of particles in the primary air stream, creating an aspirating effect for drawing secondary air into the burner along with the turbulent suspension of solid fuel particles.
