Title (EN) LOW-EMISSIONS INDUSTRIAL BURNER
(FR) BRULEUR INDUSTRIEL A EMISSIONS REDUITES
Abstract:
(EN) A burner (10) for use in both high O2 environments and low O2 environments comprises an outer tube (24) and an inner tube (26). The outer tube (24) defines a flow passage (53) and includes an inlet portion (42), an outlet portion (46), and a nozzle portion (44) interconnecting the inlet portion (42) and outlet portion (46). The inlet portion (42) has a larger effective cross-sectional area than the outlet portion (46) so that air (20) or an air-and-fuel mixture (35) moving through nozzle portion (44) is accelerated. The inner tube (26) is positioned to lie in the flow passage (53) of the outer tube (24) and is formed to include fuel-injection holes (78) to conduct fuel (33) into the flow passage (53).
(FR) Brûleur (10) convenant à la fois à une utilisation dans un environnement à haute teneur en O2 et dans une environnement à faible teneur en O2. Ce brûleur comprend un tube (24) externe et un tube (26) interne. Le tube externe (24) forme un passage (53) d'écoulement et comporte une partie (42) entrée, une partie (46) sortie et une partie ajutage (44) reliant la partie (42) entrée et la partie (46) sortie. La partie (42) entrée présente une surface effective en coupe plus importante que la partie (46) sortie de manière que l'air (20) ou le mélange (35) air-combustible traversant la partie (44) ajutage est accéléré. le tube (26) interne est placé dans le passage (53) d'écoulement du tube (24) externe et comprend des orifices (78) d'injection de combustible pour conduire le combustible (33) dans le passage d'écoulement (53).
