Premix flashback control

Commande de retour de flamme de pré-mélange

Abstract

La présente invention se rapporte à un appareil qui comprend une structure de four qui définit une zone de combustion, et un tube qui déverse un pré-mélange carburant-oxydant dans la zone de combustion à travers un orifice de sortie du tube. Un système d'alimentation en réactif utilise le tube comportant un carburant et un oxydant non mélangés pour former le pré-mélange. Un moyen de commande de retour de flamme empêche ou éteint le retour de flamme dans le tube.
An apparatus includes a furnace structure defining a combustion zone, and a tube that discharges fuel-oxidant premix into the combustion zone through an outlet from the tube. A reactant supply system provides the tube with unmixed fuel and oxidant for forming the premix. A flashback control means inhibits or extinguishes flashback in the tube.
