Title (EN) FIRE VORTEX DISPLAY
(FR) COLONNE DECORATIVE A TOURBILLON DE FEU
Abstract:
(EN) A fire vortex display for providing an interesting fire display for decorative and attention getting purposes. The display utilizes a burner (26) for burning a gaseous or liquid fuel, typically in a very fuel rich mixture. The burner is located at one end of a normally vertical transparent tube (20) such as a PyrexR tube, with a blower (30, 32) blowing air into the tube adjacent to the burner in a substantially circumferential manner to provide a swirling action for the flame given off by the burner as the flame proceeds upward into the tube. A second transparent tube (22) concentric with and somewhat larger than the first tube (20) is provided over the first tube, with the region between the two tubes (34) being ducted to form the inlet for the blower. This keeps the outer tube cool so that the fire vortex can be observed from a position close thereto and the outer tube even can be touched by an observer without danger thereto. Also disclosed are methods of controlling the fire vortex to control the direction and speed of spiraling thereof and the color of the flame.
(FR) Colonne à tourbillon de feu utile pour servir de décoration ou pour attirer l'attention. Le système utilise un brûleur (26) qui brûle un combustible gazeux ou liquide, comprenant un mélange trés riche. Le brûleur se situe à une extrémité d'un tube transparent (20) normalement vertical, comme un tube en PyrexR, et un ventilateur (30, 32) envoie de l'air dans le tube placé près du brûleur d'une manière pratiquement circonférentielle afin de produire un tourbillonnement au niveau de la flamme sortant du brûleur lorsque celle-ci monte dans le tube. Un deuxième tube transparent (22) qui est à la fois concentrique au premier tube (20) et légèrement plus large, vient recouvrir le premier tube, la zone située entre les deux tubes (34) étant équipée d'un conduit qui forme le canal d'admission du ventilateur. Grâce à cette configuration, le tube externe reste froid et on peut observer de près la colonne à tourbillon de feu, on peut même toucher le tube externe sans courir aucun danger. L'invention concerne également des procédés de régulation du tourbillon de feu qui permettent de commander la direction et la vitesse de l'enroulement à spirale de la flamme, ainsi que sa couleur.
