Description

蓄热式双旋流平焰烧嘴
技术领域：
本实用新型涉及一种把蓄热、双旋流、平焰三项技术合为一体使用的蓄热式双旋流平焰烧嘴。
背景技术：
蓄热式烧嘴是近代高温火焰炉先进节能的燃烧设备；旋流烧嘴有利于控制空燃气的不同混合程度、适合不同炉型和加热工艺要求，能形成各种形状的火焰：直焰、扩散焰、平焰，故扩大蓄热烧嘴的使用，特别是蓄热式平焰烧嘴，对均匀炉温提高加热炉效率和加热能力，尤其对众多的高温台车式加热炉减少垫铁高度，均匀炉温的效果更显著；但是它们单独使用都会存在一些不足之处，把它们的技术综合起来，结合为一体，集蓄热、双螺旋和平焰诸多优点成为一种多功能的新型烧嘴。
发明内容：
为了解决上述问题，本实用新型提供一种蓄热式双旋流平焰烧嘴，它把蓄热、双旋流、平焰三项技术合为一体，进一步提高工业炉加热质量，降低能耗，更有利环保。
技术方案：一种蓄热式双旋流平焰烧嘴，圆形保温蓄热箱体内设有蓄热体，圆形保温蓄热箱体的壁上设有装卸蓄热体盖、进冷空气管和排烟管，圆形保温蓄热箱体的顶端与喇叭型烧嘴砖连通，空气冷却、热风和燃气双旋流烧嘴设置在喇叭型烧嘴砖内，检测与点火烧嘴设在圆形保温蓄热箱体的侧壁上，且检测与点火烧嘴的点火口设在空气冷却、热风和燃气双旋流烧嘴的出气口处。
本实用新型的有益效果，一种蓄热式双旋流平焰烧嘴，它把蓄热、双旋流、平焰三项技术合为一体，进一步提高工业炉加热质量，降低能耗，更有利环保；它通过空、燃气的不同旋流角可形成不同形状火焰-直焰、扩张焰、平焰；它通过空、燃气不同旋流角可控制空燃气的混合，延迟其混合时间，解决一般蓄热式高温燃烧炉温不均，NOx过高的弊病。对蓄热式平焰烧嘴空燃气旋流角的范围分别为：α空＝45°～60°；α燃＝35°～50°；空燃气的旋流角关系，为燃气角比空气的旋流角始终少5°～10°，此旋流燃气烧嘴其管外为冷风管保护，冷风套管又用耐火保温材料保护，防止燃气管被高温烟气或预热空气烧坏。
附图说明：
图1：为本实用新型的结构示意图；
图2：为A-A剖视图；
图3：为B-B剖视图。
具体实施方式：
如图1-3所示，一种蓄热式双旋流平焰烧嘴，圆形保温蓄热箱体1内设有刚玉质￠20mm蓄热体2，圆形保温蓄热箱体1的壁上设有装卸蓄热体盖8、进冷空气管9和排烟管7，圆形保温蓄热箱体1的顶端与喇叭型烧嘴砖6连通，双旋流烧嘴3设置在喇叭型烧嘴砖6内，双旋流烧嘴3的一端设有冷风管5和进冷空气口4；检测与点火烧嘴10设在圆形保温蓄热箱体1的侧壁上，且检测与点火烧嘴10的点火口设在双旋流烧嘴3的出气口处；本实用新型将蓄热式换热器与双旋流及平焰三项技术合为一体，形成蓄热式双旋流平焰烧嘴；对蓄热式平焰烧嘴空燃气旋流角的范围分别为：α空＝45°～60°；α燃＝35°～50°；空燃气的旋流角关系，为燃气角比空气的旋流角始终少5°～10°，此旋流燃气烧嘴其管外为冷风管保护，冷风套管又用耐火保温材料保护，防止燃气管被高温烟气或预热空气烧坏。
