1. A system for burning a combustible fuel above a placement surface, the system comprising:
a body, comprising:
an upper portion;
a lower portion;
an outer wall extending between the upper portion and the lower portion;
an inner wall that is tubular in shape so as to at least partially define a fuel combustion chamber, the inner wall being spaced from the outer wall to:
form a gap between the inner wall and the outer wall, and
permit an upward flow of air in the gap between the inner wall and the outer wall;
and
one or more inner ventilation holes proximate the upper portion of the body, the one or more inner ventilation holes being configured to permit airflow from the gap between the inner wall and the outer wall in a manner that facilitates secondary combustion of compounds emitted by fuel combustion in the fuel combustion chamber;
and
a plurality of legs configured to support the body in a position spaced above the placement surface,
wherein each leg of the plurality of legs extends outwardly from beneath the body, and radially beyond the outer wall of the body, at least when the body is supported by the plurality of legs in the position spaced above the placement surface,
wherein the plurality of legs at least partially forms a stand, and
wherein the stand comprises the plurality of legs and a central intersection from which each leg of the plurality of legs radially extends.
