<p>Disclosed is an infrared radiation heater wherein a droplet of fuel formed at a lower part of a nozzle on the distal end side is prevented from falling, and thereby a dripping droplet of fuel is prevented from reaching the outside and furthermore abnormality of the nozzle can be identified. The infrared radiation heater comprisies a combustion chamber tubular body arranged substantially horizontally and defining a combustion chamber internally, a burner section provided on one end side of the combustion chamber tubular body and having nozzles arranged substantially horizontally, a combustion fan for pressure feeding combustion air toward the distal end sides of the nozzles, a swirl vane for swirling the combustion air pressure fed by the combustion fan on the distal end sides of the nozzles, an opening, for radiating heat in the combustion chamber, provided on the other end side of the combustion chamber tubular body, and a radiation body, for radiating infrared rays, provided in the opening for radiating heat, characterized in that the swirl vane is provided with an air outlet for blowing combustion air toward the lower parts of the nozzles on the distal end side.</p> |
