style="text-indent:25px">工業(yè)爐氣體燃料燃燒裝置：通常稱燒嘴，它的主要作用是按一定比例和一定的混合條件將煤氣和空氣送到爐內(nèi)燃燒（也有在燒嘴內(nèi)部燃燒的），并滿足爐內(nèi)加熱過(guò)程對(duì)火焰的要求。根據(jù)煤氣和空氣在燒嘴內(nèi)的混合情況，分為有焰和無(wú)焰燒嘴。有焰燒嘴的特點(diǎn)是：煤氣和空氣在燒嘴內(nèi)不進(jìn)行混合或*部分混合，噴到爐內(nèi)后再邊混合邊燃燒，因而火焰較長(zhǎng)并有明顯的輪廓。采用有焰燒嘴時(shí)，強(qiáng)化燃燒和組織火焰的主要手段是改變煤氣和空氣的混合條件，如將煤氣和空氣分成許多細(xì)流，使煤氣流和空氣流按一定角度相交，或利用旋流裝置促使氣流加速混合等。圖1就是一種帶單管式煤氣燒嘴。無(wú)焰燒嘴的特點(diǎn)是：煤氣和空氣在燒嘴內(nèi)部即達(dá)到均勻混合，噴出燒嘴后能立即著火燃燒，火焰很短，沒(méi)有明顯的火焰輪廓。工業(yè)爐中常用的無(wú)焰燒嘴是噴射式燒嘴（圖2）, 它是靠煤氣的噴射作用直接從大氣中按比例吸入所需要的助燃空氣，在混合管內(nèi)混合均勻后再在耐火材料制成的燃燒道中完成燃燒反應(yīng)。根據(jù)不同的用途設(shè)計(jì)相適應(yīng)的工業(yè)爐。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
