Abstract

Un générateur à feu direct approprié pour connexion à des gaines et conduits dair est décrit. Le générateur comporte une coque externe qui comprend une admission pour permettre le chauffage de lentrée dair et une sortie pour évacuer lair chauffé. Une pale de ventilateur est fonctionnellement reliée à un moteur de ventilateur pour actionner la pale de ventilateur. Le générateur comprend également une chambre de combustion définie par une paroi de chambre de combustion, une plaque chauffante à une extrémité à proximité de la pale de ventilateur et une plaque dévacuation à une extrémité opposée, la plaque chauffante possédant des ouvertures pour permettre un flux dair dans la chambre de combustion et la plaque dévacuation possédant une ouverture pour permettre la sortie de lair chauffé de la chambre de combustion, la paroi de la chambre de combustion sétendant au-delà de la plaque chauffante. Une première zone de flux dair existe entre la coque externe et la chambre de combustion, permettant un flux dair entre la pale de ventilateur et la sortie dans la coque externe. On utilise un injecteur pour injecter des gaz dans la chambre de combustion à proximité des ouvertures dans la plaque chauffante. Le générateur comprend également une coiffe entre la sortie dans la coque externe et la plaque dévacuation, la coiffe étant positionnée pour permettre un flux dair au travers la plaque dévacuation et la sortie. La plaque chauffante est située dans une position proximale de la pale de ventilateur appropriée pour générer une recirculation de lair soufflé par la pale de ventilateur pour refroidir linjecteur et la plaque chauffante pendant le fonctionnement du générateur.
