Title
(EN) GASIFICATION BURNER
(FR) BRÛLEUR DE GAZÉIFICATION
(ZH) 一种气化烧嘴
Abstract
(EN)
A gasification burner, comprising: a parent burner (1), wherein an inner side of the parent burner is provided with N levels of child burners (2), N being an integer which is greater than or equal to 1; the parent burner (1) and each level of child burners (2) are provided with an independent fuel passage and an oxidizing agent passage, respectively; the parent burner (1) and each level of child burners (2) are configured as a structure which is coaxially sleeved in sequence from outside to inside, the inner diameter of the parent burner (1) being greater than the outer diameter of a first level of child burners, and the inner diameter of each level of child burners being greater than the outer diameter of a level of child burners therebelow, which may ensure that fuel and an oxidizing agent are sufficiently and uniformly mixed within a limited reaction space and retention time, accelerating the combustion reaction rate, and thereby improving the fuel conversion rate and gasification performance of the device; at the same time, by means of adjusting the loads of the parent burner and each level of child burners, flame shape may be flexibly adjusted without reducing the load of a gasifier, thereby effectively preventing a furnace of the gasifier from overheating; the present invention may adapt to different production load requirements of project sites.
(FR)
La présente invention concerne un brûleur de gazéification, comprenant un brûleur parent (1), un côté interne du brûleur parent étant pourvu de N niveaux de brûleurs fils (2), N étant un nombre entier supérieur ou égal à 1. Le brûleur parent (1) et chaque niveau de brûleurs fils (2) sont pourvus respectivement d'un passage de combustible indépendant et d'un passage de comburant; le brûleur parent (1) et chaque niveau de brûleurs fils (2) sont configurés sous la forme d'une structure qui est emmanchée de manière coaxiale séquentiellement de l'extérieur vers l'intérieur, le diamètre interne du brûleur parent (1) étant supérieur au diamètre externe d'un premier niveau de brûleurs fils, et le diamètre interne de chaque niveau de brûleurs fils étant supérieur au diamètre externe d'un niveau de brûleurs fils inférieur. Une telle construction peut assurer un mélange suffisant et homogène de combustible et de comburant dans un espace de réaction et pendant un temps de séjour limités, ce qui accélère le taux de réaction de combustion et permet d'améliorer le taux de conversion du combustible et les performances de gazéification du dispositif. La forme de la flamme peut dans le même temps être ajustée de manière souple sans réduire la charge d'un gazéifieur, par réglage des charges du brûleur parent et de chaque niveau de brûleurs fils, ce qui permet d'empêcher efficacement un four du gazéifieur de surchauffer. La présente invention peut s'adapter à différentes exigences de charge de production de sites projets.
