Claim:
1. A method for thermally processing a solid fuel comprising: providing a heated gas from an external source; providing a bulk solids pump configured to move the solid fuel therein which includes a spool supported for rotational movement about an axis, and inlet, and outlet, a curved passage within the spool disposed in communication between said inlet and said outlet; providing a hoop surrounding at least an angular portion of the spool and mounting the hoop in fixed relationship to the axis of the spool whereby upon rotation of the spool there is relative motion between the spool and the hoop; providing one or more sleeve shaped chambers surrounding all or a portion of at least an axial extent of the said curved passage to permit containment of the heated gas within the sleeve shaped chamber(s); providing bulkheads at the axial extremities of a at least one of the sleeve shaped chambers; thermally processing said solid fuel within said pump into a thermally processed solid fuel; providing a plurality of passageways defined in said spool and or hoop; and providing a combustible gas to at least one of the sleeve shaped chambers and combusting the combustible gas within the sleeve shaped chamber.
