Title
(EN) COUNTER SWIRL DOUBLET COMBUSTOR
(FR) CHAMBRE DE COMBUSTION À DOUBLET DE CONTRE-TOURBILLON
Abstract
(EN)
An improved combustor for a gas turbine is operable to provide high combustion efficiency in a compact combustion chamber. The combustor includes a counter swirl doublet for improved fuel/air mixing. The enhanced combustor assembly and method of operation improves operation of the turbine.
(FR)
La présente invention se rapporte à une chambre de combustion perfectionnée pour une turbine à gaz, ladite chambre de combustion étant destinée à fournir une efficacité de combustion élevée dans une chambre de combustion compacte. La chambre de combustion comprend un doublet de contre-tourbillon pour permettre un meilleur mélange combustible/air. L'ensemble chambre de combustion perfectionnée et son procédé de fonctionnement améliorent le fonctionnement de la turbine.
