A feeder assembly ( 28 ) for projecting solid fuel, such as coal ( 24 ), into a combustion chamber ( 11 ) of a furnace ( 10 ) includes a distributor ( 44 ) and a feeder ( 42 ) disposed in a housing ( 40 ). The distributor ( 44 ) includes a rotor ( 48 ) having blades ( 46 ) extending outwardly therefrom, and the rotor ( 48 ) is rotatable to project the solid fuel into the combustion chamber ( 11 ). The feeder ( 42 ) includes a conveyor assembly ( 50 ) for providing the solid fuel to the rotor ( 48 ). The housing ( 40 ) includes an aperture ( 41 ) disposed therein, through which the solid fuel is projected into the combustion chamber ( 11 ). The housing ( 40 ) also includes a portion ( 45 ) movable between: a first position wherein the aperture ( 41 ) is open to allow the solid fuel to be projected into the combustion chamber ( 11 ), and a second position wherein the movable portion ( 45 ) closes the aperture ( 41 ) to shield the rotor ( 48 ) from heat emitted from the combustion chamber ( 11 ) and allow maintenance and/or replacement of the distributor ( 44 ).
