Abstract

Portable camp stove, wherein solid-fuel, especially of dried tree and bush twigs, is burned upon a supporting fuel grate positioned at bottom of a combustion-chamber. Solid-fuel is added directly into the combustion-chamber during operation through alligned stoke holes in a chimney and a vented-fire-ring, and then dropped vertically downward through an exhaust vent. Air for primary combustion is drawn into the combustion-chamber through a ring of intake apertures adjacent to and above the stove's bottom plate. Stove's outer wall is spaced apart from the wall of the combustion-chamber and the two walls are joined together and sealed by a top plate, creating an adjacent confining airspace. Air enters into said airspace through a ring of secondary air intake apertures in stove's outer-wall. where it is heated by thermal communication, as heat emitted from combusting solid-fuel passes through the combustion-chamber wall. As air in confining airspace is heated, it expands and rises, and creates an environment of positive pressure. Thusly, heated air is propelled through a ring of aperture jets cut through the wall of the combustion-chamber. where said heated air mixes in the inner combustion-chamber with gases released and sent ascending with solid fuel combusting on the fuel grate. The stream of heated air, propelled directly into and mixing with ascending gases, induces a dramatic reignition of said gases. The heat and flames released first by combusted fuel and then by the reignited gases, can be focused on heating contents in a cook pot. Two cook pots joined together at rims encase stove for storage and transport.
