A burner unit has a fuel dispersion arrangement at a burner head leading to a flame region which distributed fuel from longitudinal slots extending along trailing edges of spinner vanes of a spinner vane assembly. The spinner vane assembly is disposed transversely across a flow channel of combustion air past the burner head and has a function of deflecting the axial flow of the combustion air radially outward into a conical flow. The deflective air flow pressure distribution over the spinner vanes contributes to induction and mixing of the fuel with the combustion air as the combustion air enters the flame region of the burner. Combustion gases resulting from a combustible mixture achieved in this manner have resulted in emission products with pollutant levels within currently specified limits.

A burner unit having a longitudinal axis; a burner head disposed along the longitudinal axis; a source of forced combustion air disposed upstream of the burner head, the source generating a stream of combustion air generally along the longitudinal axis past the burner head; a flame region disposed downstream of the burner head; a fuel source coupled to the burner head; a vane assembly having a plurality of fixed vanes disposed, spaced about, and extending substantially radially outward from the longitudinal axis; each of the vanes having the shape of an airfoil and being disposed at an angle with respect to the generally axial direction of the flow of the combustion air to direct the combustion air radially outward with respect to the longitudinal axis; each of the vanes having a hollow fuel distribution chamber, the fuel distribution chambers being coupled to the fuel source; and each of the vanes having at least one opening disposed to distribute fuel from the fuel source substantially uniformly over the length of the vane to the combustion air adjacent the respective vane as the combustion air passes the vane in its path to the flame region of the burner unit.
