Radiative fire pit

A fire pit, comprising:

• an inner wall having an interior surface defining a portion of a burn chamber;
• an outer wall extending circumferentially about, and radially spaced apart from, the inner wall such that an air passage is defined between the inner wall and the outer wall;
• a radiant opening in fluid communication with the air passage, the radiant opening extending radially through an intermediate portion of the outer wall and extending about a portion of a circumference of the outer wall, the radiant opening being defined by axially opposing first and second edges of the outer wall and exposing a portion of an exterior surface of the inner wall proximate the radiant opening, the portion of the exterior surface of the inner wall proximate the radiant opening having a high emissivity coating adapted to promote emission of radiant energy from the inner wall;
• and
• a fuel grate removably positioned within the inner wall and defining a bottom surface of the burn chamber, the fuel grate being positioned axially between the first and second edges of the outer wall and further defining an air chamber axially below the fuel grate.

A fire pit, comprising:

• an inner wall having an interior surface defining a burn chamber, the inner wall having a plurality of inner ventilation holes;
• a first outer wall portion extending about, and radially spaced apart from, the inner wall to form a first air passage therebetween, the first air passage being adapted to draw a first ambient air stream through an air intake;
• a fuel grate cooperating with the inner wall to further define the burn chamber, the fuel grate having a plurality of ventilation holes formed therein;
• and
• a second outer wall portion axially spaced apart from the first outer wall portion by the air intake and having a plurality of outer ventilation holes, the outer ventilation holes being in fluid communication with the plurality of ventilation holes in the fuel grate via a second air passage, the second air passage being adapted to draw a second ambient air stream through the plurality of outer ventilation holes.

A fire pit comprising:

• an inner wall having an interior surface defining a burn chamber;
• a first outer wall portion extending about, and radially spaced apart from, the inner wall to form a first air passage therebetween,
• an inner ventilation opening extending through the inner wall and fluidly coupling the first air passage and the burn chamber;
• a first air intake configured to draw a first ambient air stream into the first air passage;
• a fuel grate cooperating with the inner wall to further define the burn chamber, the fuel grate having at least one ventilation hole,
• a second outer wall portion axially spaced apart from the first outer wall portion by the first air intake;
• a second air intake in fluid communication with the at least one ventilation hole in the fuel grate via a second air passage, the second air intake configured to draw a second ambient air stream into the second air passage at an elevation different from the first air intake.
