　　在广义的燃烧器概念中，家用的热水器、煤气灶，乃至打火机等都可以认为是燃烧器的一种。

燃气燃烧器工作原理 燃气燃烧器的特点

　　一、燃气燃烧器工作原理

　　当可燃气体（城市煤气、天然气、液化石油气）由微电脑控制系统按程序控制进入燃烧器的燃烧头内，由一次风与可燃气体混合，点火燃烧，二次风助燃，实现充分燃烧。燃烧状况由火焰自动跟踪系统检测控制燃烧，当燃烧出现故障（燃烧室缺氧、可燃气体欠压、可燃烧气体断流、气量不足等），控制系统发出指令，供气系统的电磁阀迅速关闭，切断气电源，燃烧器自动吹扫后停机，指示故障。

　　二、燃气燃烧器的特点

　　（ 1 ）热效率高 ：能适应压力波动，自行调节一次配风 （ 即燃气压力大，吸入一次风多；燃气压力小，吸入一次风少 ） ，燃烧充分，热效率高；

　　（ 2 ） 安全性高 ：该燃烧器配备小火。锅炉启动时，先点小火，当小火正常稳定燃烧时，自控系统才打开主燃气阀门，燃料才能进入锅炉正常燃烧，不会产生爆燃现象；

　　（ 3 ） 燃料适应性强：该种燃烧器只需更换少量部件就能适用于天然气、液化石油气、煤气、液化石油混合气以及其它类燃气。
