自身預(yù)熱燒嘴又稱換熱式燒嘴，它是將燃?xì)馊肟?、助燃風(fēng)入口、點(diǎn)火電極、燃燒室、換熱器和排煙口組合成一個(gè)整體的燃燒裝置。自身預(yù)熱式燒嘴的使用替代了煙道熱交換器，無(wú)需額外占地面積且熱利用效率更高。但自身預(yù)熱式燒嘴由于其應(yīng)用的特殊性和結(jié)構(gòu)復(fù)雜性，在使用過(guò)程中有很多需要注意的地方，掌握了這些注意事項(xiàng)，會(huì)在使用過(guò)程中避免很多不必要的麻煩。明火直接加熱應(yīng)用中要安裝煙氣導(dǎo)流套：在間接加熱應(yīng)用時(shí)，煙氣可以通過(guò)換熱器與輻射管的間隙排出爐膛，從而實(shí)現(xiàn)熱量的交換。在明火加熱時(shí)，我們也需要加裝煙氣導(dǎo)流套來(lái)強(qiáng)制煙氣在這個(gè)環(huán)形間隙中通過(guò)，實(shí)現(xiàn)很大程度的熱交換。換熱器與輻射管縫隙較大時(shí)安裝煙氣導(dǎo)流套：跟上一條相似，在輻射管直徑較大而燒嘴功率較小的情況下，由于換熱器與輻射管直徑的縫隙過(guò)大會(huì)造成煙氣不能貼近換熱器，影響換熱效率。所以需要加裝尺寸合適的煙氣導(dǎo)流套。 </p><p style="text-indent:25px">碳化硅燒嘴具有以下優(yōu)點(diǎn)： 1、硬度更好，燒嘴，耐沖刷性能更好，使用壽命更長(zhǎng)，成本較低。 2、材料彈性更好，噴嘴的壁厚更加薄，外形更加緊湊，同等規(guī)格的噴嘴重量更輕。而且運(yùn)輸木箱也不容易碎裂 3、材料表面光滑無(wú)氣孔，內(nèi)部流道更加光滑，不容易結(jié)垢，霧化更加均勻。 4、傳熱更好，燒嘴不容易因?yàn)槔錈峤惶娑a(chǎn)生開(kāi)裂變形。 5、另外，反應(yīng)燒結(jié)碳化硅燒嘴可以做全尺寸的螺旋燒嘴和切向空心錐燒嘴，碳化硅燒嘴套，但是氮連接碳化硅只能做2英寸以上的大流量切向空心錐燒嘴。燒嘴操作靈活,能實(shí)現(xiàn)自動(dòng)化流水線生產(chǎn)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
