• a firebox including a pair of laterally-spaced longitudinal side walls connected by a front wall and a rear wall to define a combustion chamber having an open bottom and an open top;
• and
• a frame for supporting the walls of the firebox, the frame including a skid assembly at a base of the frame, wherein the skid assembly includes a pair of laterally-spaced longitudinal skid members connected by a front portion and a rear portion to define an internal opening registering with the open bottom of the combustion chamber, and a pair of parallel guides fixed to at least one of the front portion and the rear portion for guiding the firebox apparatus as the firebox apparatus travels in a longitudinal direction relative to the roll-off track of the transport vehicle.
