Title (EN) COAL NOZZLE WITH A FLOW CONSTRICTION
(FR) BUSE À CHARBON DOTÉE D'UN ÉTRANGLEMENT D'ÉCOULEMENT
Abstract:
(EN) The invention concerns a pulverized solid fuel, in particular coal, nozzle (10) comprising an inlet opening (12) for receiving a stream of coal/air mixture (16) and an outlet opening (14) for discharging said stream (16) into a burner. The inlet opening (12) and the outlet opening (14) are fluidically connected by a flow section (18), and a flow cross section (20) of the flow section (18) varies along a flow direction (22) of the stream of coal/air mixture (16). The flow section (18) comprises a flow constriction (24) with a, preferentially globally, minimal flow cross section (26). The flow constriction (24) is fluidically located between the inlet opening (12) and the outlet opening (14) and the flow section (18) has a flow cross section (20) that, in particular continuously, increases from the flow constriction (24) to the outlet opening (14).
(FR) L'invention concerne une buse (10) pour combustible solide pulvérisé, en particulier du charbon comprenant une ouverture d'entrée (12) pour recevoir un courant de mélange charbon/air (16) et une ouverture de sortie (14) permettant d’évacuer ledit courant (16) dans un brûleur. L'ouverture d'entrée (12) et l'ouverture de sortie (14) sont raccordées fluidiquement par une section d'écoulement (18), et une section transversale d'écoulement (20) de la section d'écoulement (18) varie le long d'une direction d'écoulement (22) du courant de mélange charbon/air (16). La section d'écoulement (18) comprend un étranglement d'écoulement (24) avec une section transversale d'écoulement (26), qui est de préférence globalement minimale. L'étranglement d'écoulement (24) est fluidiquement situé entre l'ouverture d'entrée (12) et l'ouverture de sortie (14) et la section d'écoulement (18) a une section transversale d'écoulement (20) qui augmente, en particulier de façon continue, de l'étranglement d'écoulement (24) à l'ouverture de sortie (14).
