Title
(EN) FUEL DISTRIBUTION DEVICE AND BURNER
(FR) DISPOSITIF DE DISTRIBUTION DE COMBUSTIBLE ET BRÛLEUR
(ZH) 一种燃料分配装置和燃烧器
Abstract
(EN)
A fuel distribution device (9) for a burner is provided, which includes an inlet end (9a), an outlet end (9b), a distribution channel (9c) extending between the two ends, and n feed pipes extending from the inlet end (9a) to the distribution channel (9c). N groups of distribution ports are provided at the outlet end (9b), and each group includes m distribution ports uniformly distributed around the circumference of the outlet end (9b). Each fuel feed pipe (5) is branched into m feed branch pipes which are connected with the m distribution ports of each group respectively. M and n are positive integers which are larger than or equal to 2. The fuel distribution device (9) ensures that the fuel can be uniformly distributed from the outlet end (9b) when one or more of the feed pipes (5) is out of order.
(FR)
La présente invention se rapporte à un dispositif de distribution de combustible (9) pour un brûleur. Le dispositif selon l'invention comprend un côté d'amenée (9a), un côté de sortie (9b), un canal de distribution (9c) qui s'étend entre un côté et l'autre, et n tuyaux d'alimentation qui s'étendent entre le côté d'amenée (9a) et le canal de distribution (9c). N groupes d'orifices de distribution sont prévus sur le côté de sortie (9b) et chaque groupe comprend m orifices de distribution uniformément répartis autour de la circonférence du côté de sortie (9b). Chaque tuyau d'alimentation en combustible (5) se ramifie en m tuyaux d'alimentation ramifiés qui sont raccordés, respectivement, aux m orifices de distribution de chaque groupe. M et n sont des nombres entiers positifs qui sont supérieurs ou égaux à 2. Le dispositif de distribution de combustible selon l'invention (9) garantit une distribution uniforme du combustible depuis le côté de sortie (9b) quand un ou plusieurs des tuyaux d'alimentation (5) est hors service.
