Firepit with plenum surrounding combustion chamber and a subterranean air intake port in an outer shell

Abstract

A firepit, having an outer shell having a first base and a first sidewall extending upwardly from the first base to a first top to define a first cavity; an inner shell disposed within the first cavity, defining a second base and a second sidewall extending upwardly from the second base to a second top of the inner shell that is level with the first top to define a second cavity, the second cavity defines a combustion chamber; a base spacer disposed between the first and second bases, a sidewall spacer between the first and second sidewalls, to define a plenum between the outer shell and the inner shell; a first air inlet port defined in the first sidewall; second air inlet ports defined in the second base so that an airflow through the first air inlet port flows through the second air inlet ports and into the combustion chamber.
