ABSTRACT:
An apparatus for improving mixing and uniformity of furnace combustion gases in a boiler includes a slag screen 50, slag screen baffle 62 with a plurality of wingwall sections 52 situated between cyclone burner riser sections 64. This arrangement improves overall distribution of the burner exit gases 56 and uniformity by reducing stratification of the gases 58 exiting the burner. Additionally, the present invention increases the heat transfer effectiveness and ash collecting capability.
