Abstract
An air heating burner having improved CO emissions across a broad range of heat inputs. The burner incorporates wings which cover portions of mixing plates associated with low to medium-low fire. The wings reduce air flow velocity to eliminate quenching during such conditions, thereby increasing combustion temperature and reducing CO emissions. The wings also form pre-heat chambers which further increase combustion temperature. The burner produces a substantially consistent level of CO emissions across the range of inputs, regardless of the pressure drop across the burner.
