A smoking device can include one or more walls defining, at least in part, a combustion cavity, a lower inlet connecting the combustion cavity to an air source, a first flange defining, at least in part, a first recirculation channel open to an upper side of the combustion cavity, a second flange defining, at least in part, a second recirculation channel open to the upper side of the combustion cavity, and an upper inlet connecting the upper side of the combustion cavity to the air source and disposed between the first recirculation channel and the second recirculation channel. While a flame is generated within the combustion cavity, a convection flow from the flame can be directed to the first recirculation channel and the second recirculation channel and past the upper inlet to reduce the upper flow of air from the upper inlet until the flame is reduced.
