電蒸汽鍋爐廠家http://www.akcaya.com/介紹說燃用發(fā)熱量高的燃?xì)?，要使燃?xì)饽艹浞秩紵枰罅康目諝馀c之混合。電蒸汽鍋爐的燃燒方法可歸類為以下三種：
1、擴(kuò)散燃燒即不預(yù)先混合，而是在燃?xì)鈬娮炜谙嗷U(kuò)散，并燃燒。其優(yōu)點(diǎn)燃燒穩(wěn)定，燃具結(jié)構(gòu)簡(jiǎn)單，但火焰較長(zhǎng)，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(yù)混部分空氣燃燒即燃燒前預(yù)先將一部分空氣與燃?xì)饣旌?，然后進(jìn)行燃燒。其優(yōu)點(diǎn)是燃燒火焰清晰，燃燒強(qiáng)化，熱效率高。但燃燒不穩(wěn)定，對(duì)一次空氣的控制及燃燒成分要求較高。燃?xì)馊紵饕话愣嘤么朔N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、無焰燃燒即燃?xì)馑杩諝庠谌紵耙雅c燃?xì)饩鶆蚧旌?。一次空氣過剩系數(shù)等于燃料完全燃燒時(shí)的空氣過剩系數(shù)，在燃燒過程中不需要從周圍空氣中取得氧氣。當(dāng)燃?xì)馀c空氣混合物達(dá)到燃燒區(qū)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.
