Non-gas fire pit

A fire pit comprising:

• an inner chamber wall circumscribing and defining an inner chamber;
• a plurality of primary air apertures defined through the inner chamber wall at a first, lower level;
• a plurality of secondary air apertures defined through the inner chamber wall at a second, upper level;
• a fuel grate supported within the inner chamber at a level between the lower level and the upper level;
• and
• an outer wall surrounding the inner chamber wall to define an air intake chamber therebetween;
• wherein solid fuel supported by the fuel grate, when combusted, is provided primary air from below the fuel grate by the primary air apertures and provided secondary air above the solid fuel by the secondary air apertures, the secondary air promoting combustion of unburned gasified combustibles rising within the inner chamber;
• wherein at least some air entering the inner chamber via the secondary air apertures is heated by passing in proximity to the inner chamber wall through the air intake chamber;
• and
• wherein the inner chamber wall is frustoconical with a smaller upper end and a larger lower end and the outer wall is frustoconical with a larger upper and a smaller lower end, the inner chamber wall and the outer wall joining at the lower ends thereof and being spaced apart at the upper ends thereof, the space being covered by a top panel to enclose the air intake chamber.
