摘要： Brûleur comportant des canaux circulaires sensiblement concentriques (2, 3, 9, 13) servant à amener divers fluides combustibles (B, C, E, F), ainsi qu'une canalisation d'air circulaire et extérieure sensiblement conique (4), dans lequel un combustible gazeux (B) ou un combustible liquide (C), arrivant par une pluralité de tuyères de sortie (11, 14) peut être mélangé intimement avec le courant d'air (A) traversant la canalisation circulaire (4). Au-dessus des tuyères de sortie (11, 14), côté arrivée, un autre canal circulaire (16) débouche dans la canalisation d'air circulaire (4). Cet autre canal circulaire (16) sert à amener un gaz de combustion à faible pouvoir calorifique, par exemple du gaz de houille, tandis que le brûleur selon l'état de la technique peut, en outre, être exploité comme brûleur à prémélange avec du gaz et/ou de l'huile. Pour tous les combustibles et modes de fonctionnement, l'émission de NOX vers l'environnement peut être minimisée.

摘要： The present invention relates to a combustion system for a gas turbine. The combustion system comprises a combustion chamber (100) having an end section (101) and a pre-combustion section (102) extending from the end section (101) along a centre axis (103) of the combustion chamber (100), a swirler device (110), an optional pilot burner device (120) and a light emitting arrangement (130). The swirler device (110) is mounted to the pre-combustion section (102) such that a main fuel (111) is injectable by or through the swirler device (110) into an inner volume (104) of the pre- combustion section (102). The main flame (108) using the main fuel (111) is producible inside the inner volume (104). The optional pilot burner device (120) is mounted to the end section (101) of the combustion chamber (100) such that a pilot fuel (121) is injectable by or through the pilot burner device (120) into the inner volume (104) of the pre-combustion section (102), wherein a pilot flame (122) using the pilot fuel (121) is producible inside the inner volume (104) for stabilizing the main flame (108). The light emitting arrangement (130) emits an electromagnetic radiation (131) into the inner volume (104), wherein the light emitting arrangement (130) is arranged to the combustion chamber (100) such that an energy input to the pilot flame (122) and/or the main flame (108) is generatable by the electromagnetic radiation (131) for stabilizing the pilot flame (122) and/or the main flame (108), particularly to reduce the fuel required by the pilot flame and hence the emissions. The light emitting arrangement could also be used to replace the function of the pilot flame and be used to stabilise the main flame instead of using a pilot flame.
