ABSTRACT:
A pulverized fuel burner having lower emissions and lower unburned fuel losses by outwardly diverting and swirling pulverized fuel at the outlet of a fuel nozzle carrying the pulverized fuel. Diverting cone is positioned at the outlet of the fuel nozzle and include swirling plates connected there between for outwardly diverting some of the pulverized fuel and swirling a remainder of the pulverized fuel. Together these effects reduce the axial momentum of the fuel, shortening the flame and improving its emission and unburned fuel loss characteristics.
