Title
(EN) TWO-STAGE FUEL BURNING ROW BURNER
(FR) BRÛLEUR DE RANGÉE DE COMBUSTION DE COMBUSTIBLE À DEUX ÉTAGES
(ZH) 一种两级燃烧式火排燃烧器
Abstract
(EN)
A two-stage fuel burning row burner comprises a base (10) and a plurality of flame sheet members (20) provided at the base (10). The base (10) is provided with fuel gas jets (11) aligned with the flame sheet members (20). The fuel gas jet (11) injects a fuel gas into the flame sheet member (20). The injected fuel gas can bring air into the interior of the flame sheet member (20) and mix with the same to form a pre-mixed gas. The pre-mixed gas can be discharged from a hole (21) arranged at an upper portion of the flame sheet member (20) and burn. Since the pre-mixed gas inside the flame sheet member (20) can undergo incomplete combustion, a secondary air supply channel (30) is arranged between every two adjacent flame sheet members (20) to supply air to a flame at the hole (21). The burner enables full combustion of a fuel gas, produces a more uniform flame, and can further reduce emissions of nitrogen oxide and carbon monoxide.
(FR)
La présente invention concerne un brûleur de rangée de combustion de combustible à deux étages comprenant une base (10) et une pluralité d'éléments plats de flamme (20) disposés au niveau de la base (10). La base (10) est dotée de jets de gaz combustible (11) alignés avec les éléments plats de flamme (20). Le jet de gaz combustible (11) injecte un gaz combustible dans l'élément plat de flamme (20). Le gaz combustible injecté peut apporter de l'air à l'intérieur de l'élément plat de flamme (20) et se mélanger à celui-ci pour former un gaz pré-mélangé. Le gaz pré-mélangé peut être évacué d'un trou (21) agencé au niveau d'une partie supérieure de l'élément plat de flamme (20) et subir une combustion. Comme le gaz pré-mélangé à l'intérieur de l'élément plat de flamme (20) peut subir une combustion incomplète, un canal d'alimentation en air secondaire (30) est agencé entre chaque paire d'éléments plats de flamme adjacents (20) pour fournir de l'air à une flamme au niveau du trou (21). Le brûleur permet la combustion complète d'un gaz combustible, produit une flamme plus uniforme et peut en outre réduire les émissions d'oxyde d'azote et de monoxyde de carbone.

一种两级燃烧式火排燃烧器,包括底座(10)和设置在底座(10)上的若干火片(20),底座(10)上设置有与火片(20)对齐的燃气喷嘴(11),燃气喷嘴(11)用于向火片(20)内喷射燃气,喷射的燃气能够带动空气进入到火片(20)内而形成预混气体,预混气体能够自火片(20)上部的火孔(21)排出和燃烧,火片(20)内的预混气体能够进行缺氧燃烧,各两相邻火片(20)之间具有用于给火孔(21)处火焰补充空气的二次空气补充通道(30),该燃烧器燃烧更加充分、火焰更为均匀,能进一步降低氮氧化物和一氧化碳的排放量。
