ABSTRACT:
A burner assembly includes a register having a circular front wall and an annular side wall; a plurality of cylindrical bluff body elements circumferentially spaced about the annular side wall in a plurality of axially spaced rows for supplying air to the register; fuel supply assemblies which supply at least one of coal, gas and oil to the register for mixing with the air; and a plurality of bluff body discs, each positioned within a respective bluff body element for increasing the velocity and pressure drop of the air entering the register so as to enhance mixing of the fuel and the air within the register, and to reduce the NOx.
