ABSTRACT:
A burner assembly cofires a primary solid fuel and a secondary solid fuel in a combustion zone of a boiler. The burner assembly includes a fuel injector that mixes the primary solid fuel and the secondary solid fuel prior to injection into the combustion zone of the boiler. The primary solid fuel may be pulverized coal, pulverized petroleum coke, or the like, while the secondary solid fuel may be a biomass fuel or refuse-derived fuel.
