電蒸汽鍋爐廠(chǎng)家http://www.hbyuandong.com.cn/介紹說(shuō)燃用發(fā)熱量高的燃氣，要使燃氣能充分燃燒，需要大量的空氣與之混合。電蒸汽鍋爐的燃燒方法可歸類(lèi)為以下三種：
1、擴散燃燒即不預先混合，而是在燃氣噴嘴口相互擴散，并燃燒。其優(yōu)點(diǎn)燃燒穩定，燃具結構簡(jiǎn)單，但火焰較長(cháng)，易產(chǎn)生不完全燃燒，使受熱面積碳化。
Diffusion combustion that is not pre-mixed, but the mutual diffusion of the gas nozzle orifice, and burning. The advantage combustion stability, simple gas appliance structure, but the flame is longer, easy to produce incomplete combustion, heated area carbonation.
2、預混部分空氣燃燒即燃燒前預先將一部分空氣與燃氣混合，然后進(jìn)行燃燒。其優(yōu)點(diǎn)是燃燒火焰清晰，燃燒強化，熱效率高。但燃燒不穩定，對一次空氣的控制及燃燒成分要求較高。燃氣燃燒器一般多用此種燃燒方式。
That part of the air premixed combustion air prior to combustion in advance is mixed with a portion of the gas, and then combusted. The advantage is clear burning flame, burning strengthen, high thermal efficiency. But unstable combustion and combustion control components require a higher primary air. Gas burners generally burn more such manner.
3、無(wú)焰燃燒即燃氣所需空氣在燃燒之前已與燃氣均勻混合。一次空氣過(guò)剩系數等于燃料完全燃燒時(shí)的空氣過(guò)剩系數，在燃燒過(guò)程中不需要從周?chē)諝庵腥〉醚鯕?。當燃氣與空氣混合物達到燃燒區后能在瞬間燃燒完畢。
Flameless combustion air that is required prior to combustion gas has been uniformly mixed with the gas. Once the excess air coefficient is equal to the excess air ratio for complete combustion of the fuel required to obtain oxygen from the ambient air in the combustion process. When a mixture of gas and air to reach the combustion zone to burn is completed in an instant.
