Hot combustion products flow downward from a combustion zone between a central pillar and the IR emitter, and then upward between the emitter and a tubular IR transparent window. The cell arrays are spaced outward from a convection barrier tube and a short pass filter. A burner assembly at the top of the pillar has an alternating arrangement of accelerating air channels with large openings to the air supply and slowing mixing channels with small openings to the air supply. Radial fuel channels connect the central fuel supply with the peripheral mixing channels. Release of accelerated air creates turbulence in the combustion zone where the air and fuel further mix and are ignited. A cavity in the pillar supplies liquid fuels which are atomized by ultrasonic energy from a central rod. The atomized liquids are released through small holes into the combustion zone. Exhaust gases preheat the air supply which is in an upward tubular extension of the IR emitter.Other References
