Split nozzle tip for pulverized coal burner
A nozzle tip is described for a burner on a pulverized fuel fired furnace comprising: a. an open-ended inner shell having an inlet end and an outlet end and defining therebetween a flow passageway through which a mixture of pulverized fuel and transport air passes from the burner into the furnace; b. an open-ended outer shell spaced from and surrounding the inner shell thereby defining an annular flow passageway therebetween through which additional air passes from the burner into the furnace; and c. first and second splitter plates disposed within the inner shell, each having a leading edge portion disposed transversely across the flow passageway of the inner shell at the inlet end thereof and a trailing edge portion extending transversely across the flow passageway of the inner shell at the outlet end thereof. The first and second splitter plates converge at the inlet end of the inner shell and extend outwardly therefrom in a diverging manner toward the outlet end of the inner shell. The first and second splitter plates thereby divide the flow passageway through the inner shell into a first flow passage bounded by the first splitter plate and the inner shell and a second flow passage bounded by the second splitter plate and the inner shell.
