Title (EN) METHOD AND APPARATUS FOR INTRODUCING SOLID MATERIAL INTO A COMBUSTION OR GASIFICATION REACTOR
(FR) PROCEDE ET APPAREIL SERVANT A INTRODUIRE UN MATERIAU SOLIDE DANS UN REACTEUR DE COMBUSTION OU DE GAZEIFICATION
Abstract:
(EN) A method and apparatus for introducing fuel or some other solid material into a combustion or gasification boiler. The blowdown water from the steam drum of the boiler is used as the medium for moistening the solid material to be fed into the boiler prior to the feed and/or as the medium, in the feed nozzles, for dispersing and distributing the material into the boiler.
(FR) Procédé et appareil servant à introduire un combustible ou un autre matériau solide dans une chaudière de combustion ou de gazéification. L'eau purgée de la chaudière supérieure sert de milieu pour humecter le matériau solide avant qu'il ne soit introduit dans la chaudière, et/ou de milieu, placé dans les ajutages d'alimentation, destiné à disperser et à distribuer le matériau dans la chaudière.
