Title (EN) COAL NOZZLE ASSEMBLY FOR A STEAM GENERATION APPARATUS
(FR) ENSEMBLE BUSE À CHARBON DESTINÉ À UN APPAREIL DE PRODUCTION DE VAPEUR
Abstract:
(EN) A steam generating system includes a nozzle assembly for pulverized coal and air, the coal nozzle assembly comprises an inner housing (3) for conveying primary air and coal and an outer housing (5) for conveying secondary air to an exit face (13) of a nozzle tip (1), wherein the outer housing (3) and the inner housing (5) are arranged coaxially and limit a channel (15) for the secondary air, wherein the cross-sectional area (AIH) of the inner housing (3) increases towards the exit face (13) of the nozzle tip (1), wherein the cross-sectional area (AOH) of the outer housing (5) decreases towards the exit face (13), and wherein bars (11) are located in the inner housing (3) near the exit face (13) that accelerate the velocity of the primary air and coal particles.
(FR) L'invention concerne un système de production de vapeur comprenant un ensemble buse pour du charbon pulvérisé et de l'air, l'ensemble buse à charbon comprenant une enveloppe interne (3) destinée à transporter de l'air primaire et du charbon et une enveloppe externe (5) destinée à transporter de l'air secondaire vers une face de sortie (13) d'un embout de buse (1), l'enveloppe externe (3) et l'enveloppe interne (5) étant agencées de manière coaxiale et limitant un canal (15) pour l'air secondaire. L'aire en section transversale (AIH) de l'enveloppe interne (3) augmente vers la face de sortie (13) de l'embout de buse (1), l'aire en section transversale (AOH) de l'enveloppe externe (5) diminue vers la face de sortie (13), et des barres (11) sont situées dans l'enveloppe interne (3) à proximité de la face de sortie (13) afin d'accélérer la vitesse de l'air primaire et des particules de charbon.
