Description

预混式可调节燃气烧嘴及方法
技术领域：
本发明具体涉及一种预混式可调节燃气烧嘴及方法，属于窑炉的燃烧技术领域，适应于耐火材料的燃烧应用。 
背景技术：
就发明人所知，目前国内用于耐火材料烧结过程中使用的燃烧装置是固定位置安装的，调节燃烧器时经常调节各种阀门，这样操作不利窑炉内气氛稳定，主要是空气和天然气混合不好造成天然气的浪费。 
发明内容：
本发明的目的就是为了克服上述缺陷，提供一种能够使窑炉内气氛稳定，空气和天燃气充分混合可以使空气和天燃气合理利用而且燃烧效率高的预混式可调节燃气烧嘴及方法。 
本发明是按照以下技术方案实现的，所述的预混式可调节燃气烧嘴及方法，其特征在于设置一条燃气管5，燃气管5与混合管4固定链接，混合管4套设在燃气管5的外面，混合管4上设置有次风口3，混合管4与空气管1之间留有一定间隙，空气管1套设在混合管4的外面，空气进气管1上设置有主风口2。 
本发明的预混式可调节燃气烧嘴及方法，是天燃气通过燃气管，使天燃气和空气在混合管充份混合，然后使混合气从混合管喷出，混合气火焰向隧道窑内喷火，实现了隧道窑对烧制物的烧结，包括；空气管，混合管，燃气管。 
本发明的预混式可调节燃气烧嘴及方法，具有明显地提高了烧结质量和烧结速度，可以正确满足窑炉温度恒定，实施在耐火材料烧结过程中。有效利用混合气火焰，减少燃料的用量，节能高效的优点。 
附图说明：
附图1为预混式可调节燃气烧嘴及方法结构图 
其中：1.空气管，2.主风口，3.次风口，4.混合管，5.燃气管。 
具体实施方式；
如图1所示本发明预混式压力调节二次燃气烧嘴及方法具体实施方式，其特征在于设置一条燃气管5，燃气管5与混合管4固定链接，混合管4套设在燃气管5的外面，混合管4上设置有次风口3，混合管4与空气管1之间留有一定间隙，空气管1套设在混合管4的外面，空气进气管1上设置有主风口2。 
本发明中，通过调节混合管使燃气混合气火焰有效的利用，天燃气和空气在混合管充份混合，调节主风口和次风口进气量合理对燃气进行混合可以减少燃气的用量。
