Title
(EN) GRADUAL COMBUSTION TYPE FIRE PLATE COMBUSTOR
(FR) CHAMBRE DE COMBUSTION À PLAQUE D'ALLUMAGE DE TYPE À COMBUSTION PROGRESSIVE
(ZH) 一种冉燃式火排燃烧器
Abstract
(EN)
A gradual combustion type fire plate combustor, comprising a base (10) and fire plates (20) provided on the base (10), wherein the interior of each fire plate (20) comprises a gas channel (21); fire holes (22) communicated with the gas channel (21) are provided on the top plate of the fire plate (20); the left and right side of the top plate both comprise guide parts (23) that are inclined upwards from inside to outside; the fire holes (22) are provided on the guide parts (23); each fire hole (22) is lateral elongated and laterally extends to the side plate of the fire plate (20) to form a gradual combustion hole (24). The combustor can form high-temperature microcirculation, reduce the emission of nitrogen oxide and carbon monoxide, and have no heat energy loss.
(FR)
L'invention concerne une chambre de combustion à plaque d'allumage de type à combustion progressive, comprenant une base (10) et des plaques d'allumage (20) disposées sur la base (10), l'intérieur de chaque plaque d'allumage (20) comprenant un canal à gaz (21) ; des orifices d'allumage (22) en communication avec le canal à gaz (21) sont disposés sur la plaque supérieure de la plaque d'allumage (20) ; les côtés gauche et droit de la plaque supérieure comprennent tous deux des parties de guidage (23) qui sont inclinées vers le haut depuis l'intérieur vers l'extérieur ; les orifices d'allumage (22) sont disposés sur les parties de guidage (23) ; chaque orifice d'allumage (22) est allongé latéralement et s'étend latéralement vers la plaque latérale de la plaque d'allumage (20) pour former un orifice de combustion progressive (24). La chambre de combustion peut former une microcirculation à haute température, réduire l'émission d'oxyde d'azote et de monoxyde de carbone et peut ne pas présenter de perte d'énergie thermique.
(ZH)
一种冉燃式火排燃烧器,包括底座(10)和设置在底座(10)上的火片(20),火片(20)的内部具有燃气通道(21),火片(20)的顶板上设置有与燃气通道(21)相连通的火孔(22),顶板的左部和右部均具有自内侧向外侧朝上倾斜的导引部(23),火孔(22)设置在导引部(23)上,火孔(22)呈侧向的长条形并侧向延伸至火片(20)的侧板上而形成冉燃孔(24),该燃烧器可以形成高温微循环,减少氮氧化物和一氧化碳排放量,没有热能损失。
