An apparatus for preventing ash build-up and clinker formation of a particulate fuel mass in a stove includes a grate having a plurality of openings therein and on which the particulate fuel mass resides. A bottomless container retains the particulate fuel mass on the grate. The grate is reciprocated with respect to the bottomless container and the particulate fuel mass such that the position of the grate openings is altered relative to the particulate fuel mass to channel stove air flow through various portions of the particulate fuel mass.
