一种负压高温气燃烧器

Abstract

本实用新型公开了一种负压高温气燃烧器，具体涉及气燃烧器技术领域，包括主气枪和点火气枪，所述点火气枪设在主气枪一侧，所述主气枪后端连通有配风管，所述点火气枪后端贯穿配风管并与配风管内部连通，所述配风管内部设有过滤组件，所述主气枪内部设有导热空心管，所述导热空心管外壁固定设有多个呈环形阵列分布的导热限位板，所述主气枪内壁和配风管内壁均开设有与导热限位板相适配的限位槽。本实用新型通过导热空心管及多个导热限位板可将主气枪产生的部分热量传导至配风管内部，实现对气源的预热，从而提升燃烧效果，同时，套筒内的过滤网能对气源中的杂质进行过滤，避免杂质阻碍气源在主气枪和点火气枪内的流动，保证流速稳定。
