A portable field stove is adapted to assume a collapsed configuration for storage and a set-up configuration for supporting a utensil above a portable heat source. The stove includes self-locking features that wedge a bottom plate against a shoulder and against a front plate to lock the stove into the set-up configuration. The stove also includes cutouts, openings and holes which are arranged and configured to permit only the proper amount of air to flow into the stove and to direct that air so that it does not flow across the heat source. The cutouts, openings and holes are also arranged to establish an air flow pattern through the stove that efficiently uses the heat generated by the heat source. The stove can also be used in an inverted orientation.
