Abstract[English]
Burner (100) and method for inhibiting effects of flashback on the burner are disclosed. The burner includes a combustor can (102) and plurality of premixing tubes (104) circumferentially arranged about a longitudinal axis (106) of the combustor can. Each respective premixing tube extends to an outlet (108) of the respective premixing tube, where each premixing tube defines a respective gap (110) relative to an adjacent premixing tube, and where each premixing tube is arranged to form a jet flame in a combustion zone (114) disposed downstream from the outlet. A fluidic injection arrangement (120) is configured to form a fluidic barrier to inhibit ingestion of jet flames through the respective gaps and thereby inhibit effects of flashback on the burner.[French]
L'invention concerne un brûleur (100) et un procédé d'inhibition d'effets de retour de flamme sur le brûleur. Le brûleur comprend une enveloppe de chambre de combustion (102) et une pluralité de tubes de prémélange (104) agencés de manière circonférentielle autour d'un axe longitudinal (106) de l'enveloppe de combustion. Chaque tube de prémélange respectif s'étend jusqu'à une sortie (108) du tube de prémélange respectif, chaque tube de prémélange définissant un espace (110) respectif par rapport à un tube de prémélange adjacent, et chaque tube de prémélange étant agencé pour former un jet de flamme dans une zone de combustion (114) disposée en aval de la sortie. Un agencement d'injection fluidique (120) est configuré pour former une barrière fluidique pour empêcher l'ingestion de jets de flammes à travers les espaces respectifs et ainsi inhiber les effets de retour de flamme sur le brûleur.
