Title
(EN) BURNER AND COMBUSTION DEVICE COMPRISING SAID BURNER
(FR) BRÛLEUR ET DISPOSITIF DE COMBUSTION COMPRENANT LEDIT BRÛLEUR
Abstract
(EN) The burner (1) according to the invention comprises a main body (10) provided with an operating cavity (11) open at least on a first side. The burner also comprises first feed means (20) arranged to introduce a flow of a first reagent (for example combustion air) into said cavity and second feed means (31) are arranged to introduce a flow of a second reagent (for example fuel) into the same operating cavity. The first means are configured so as to introduce the first reagent according to a tangential direction, while the second means are configured to introduce the second reagent according to a direction parallel to the direction in which the cavity extends. According to the invention the operating cavity comprises a first portion between the intake position of the first reagent and the intake position of the second reagent. This first portion defines a stabilization chamber of the flow of the first reagent. The operating cavity also comprises a second portion defining a combustion chamber downstream of the intake position of the second reagent.
(FR) L'invention porte sur un brûleur (1) qui comprend un corps principal (10) qui comporte une cavité de fonctionnement (11) ouverte sur au moins un premier côté. Le brûleur comprend également des premiers moyens d'alimentation (20) conçus pour introduire un écoulement d'un premier réactif (par exemple de l'air de combustion) dans ladite cavité et des seconds moyens d'alimentation (31) sont conçus pour introduire un écoulement d'un second réactif (par exemple un combustible) dans cette même cavité de fonctionnement. Les premiers moyens sont configurés de façon à introduire le premier réactif selon une direction tangentielle, tandis que les seconds moyens sont configurés pour introduire le second réactif selon une direction parallèle à la direction dans laquelle s'étend la cavité. Selon l'invention, la cavité de fonctionnement comprend une première partie entre la position d'admission du premier réactif et la position d'admission du second réactif. Cette première partie définit une chambre de stabilisation de l'écoulement du premier réactif. La cavité de fonctionnement comprend également une seconde partie définissant une chambre de combustion en aval de la position d'admission du second réactif.
