Abstract

一种锅炉燃气用矩环形烧嘴,由2n层矩形套管 构成,n为1~5间正整数,各层套管间用筋板固定支 撑。可燃气体和助燃气体间层射出,可燃气体为助燃 气体所包围。由于矩环形烧嘴结构合理,形状最佳, 所以具有混气均匀、燃烧稳定、不易变形、使用寿命长 等特点。实施中不存在回火现象,寿命可达5万小时 以上。

Description

本实用新型涉及一种矩环型烧嘴,特别适用于锅炉用燃气燃烧器,具有烧气量大、混合均匀、燃烧稳定和使用寿命长等特点。
在现有的锅炉燃气燃烧器中,采用的烧嘴多为横向缝隙式,其喷口为多层扁细状,且煤气与助燃气体间层射出。由于其喷口形状的缘故,使其在受高温和喷嘴内外压差的作用下,极易变形,从而造成气体配比变化,喷嘴烧损等现象。使用寿命较短。
本实用新型的目的就是要提供一种混合效果好,使用寿命长的矩环型烧嘴。
本实用新型的短环型烧嘴结构及其特点结合附图说明如下:
附图1为矩环型烧嘴结构剖面图。
附图2是矩环型烧嘴喷口断面图。
如图1所示,本实用新型的短环型烧嘴为矩形套管结构,主要由可燃气体接口(1)、助燃气体接口(2)、可燃气体导管(3)、助燃气体导管(4)和筋板(5)等组成。可燃气体和助燃气体分别从烧嘴的端头和侧面进入烧嘴,再经各自的导管最后从喷口射出。图2示出了矩环型烧嘴喷口断面,矩型套管共分为2n层,n为1~5间的正整数,其中心管和最外层套管及其隔层管为助燃气体导管,其余为可燃气体导管。各层套管间分别用筋板(5)固定,以防变形。各层套管的断面积可根据可燃气体和助燃气体成分以及供气量的大小而设定。
本实用新型的矩环型烧嘴,由于可燃气体被助燃气体所包围,且两种气体均以矩环形间层气流射出,所以混合效果好,燃烧充分。各层套管间用筋板(5)固定支撑,不易变形,使用寿命长。实施例中不存在回火现象,寿命达5万小时以上。

Claims (2)
