style="text-indent:25px">按照燒嘴前天然氣的壓力高低：低壓天然氣燒嘴：天然氣壓力在5kpa以下。高中壓天然氣燒嘴：天然氣壓力在5kpa以上。按照火焰的形狀類型：直焰燒嘴：又稱長焰燒嘴，火焰較長，一般窯爐上采用較多。短焰燒嘴：火焰短而有剛性。平焰燒嘴：火焰緊貼爐墻或是爐頂內(nèi)部向四周均勻伸展的圓盤形狀噴出。按照空氣供給方式分類：自吸式燒嘴：燒嘴不需要借助外力配風(fēng)，自身文丘里式結(jié)構(gòu)，可吸入外界空氣，一般燒嘴功率較小。配風(fēng)式燒嘴：依靠鼓風(fēng)機強制配助燃風(fēng)，風(fēng)機通常為高壓離心風(fēng)機。按照空燃混合方式：擴散式燒嘴：燃燒所需要的空氣不預(yù)先和天然氣混合。大氣式燒嘴：又稱半預(yù)混合天然氣燒嘴。燃燒所需要的空氣部分與天然氣混合。完全預(yù)混合式燒嘴：燃燒所需要的空氣預(yù)先和天然氣混合，一般多用在無焰燃燒類型的燒嘴上。特殊功能分類：可分為蓄熱式燒嘴、輻射管燒嘴、可調(diào)溫?zé)?、低氮燒嘴等多種新型節(jié)能燒嘴。燒嘴的燃燒方式是煤氣與空氣不預(yù)先混合，而是分別送入燃燒室或窯內(nèi)進行混合燃燒。</p><div

style="text-indent:25px">小編為您介紹燒嘴性能供大家參考：（1）霧化效果根據(jù)燒嘴的原理利用高速噴出原料氣體與其它原料物流混合均勻，達到理想的混合。通過對燒嘴的液霧平均粒徑、霧粒直徑分布、霧炬張角和液霧流量密度分布等指標(biāo)的測定，獲得設(shè)計條件下比較優(yōu)良的數(shù)據(jù)，并比較終經(jīng)過實際生產(chǎn)的工藝指標(biāo)的驗證。（2）氣化爐的高度和直徑在設(shè)計參數(shù)狀態(tài)下，噴射出來的反應(yīng)物氣流的張角應(yīng)該有一個合理的開度，不宜直接沖刷到耐火磚的墻面。其工作狀態(tài)下的火焰長短（反應(yīng)高溫區(qū)位置）應(yīng)該合理，長短合適，以避免對耐火磚及燒嘴本身帶來不利的影響。因此，氣化爐的設(shè)計應(yīng)該有一個合理的高度和直徑，使燒嘴的比較佳工作狀態(tài)與氣化爐相匹配，并留有一定的余地。（3）操作彈性要有一個合適的操作彈性，使其能夠滿足系統(tǒng)開車時的低負荷、正常生產(chǎn)時的滿負荷以及單爐運行時的超負荷（50%～130%）能力，在上述操作彈性范圍內(nèi)應(yīng)保證其正常的工作性能。（4）使用壽命在保證其工作性能的前提下，較大限度地延長其使用壽命，以確保裝置的長周期穩(wěn)定運行及經(jīng)濟運行效能。確切地說，一個無維修運轉(zhuǎn)周期應(yīng)該在一年以上，建議為5～10年。燃氣燒嘴主要特點：燃燒充份、不污染環(huán)境、加熱質(zhì)量好、操作方便、節(jié)能降耗明顯等特點。深圳燃氣燒嘴哪家便宜</p><p style="text-indent:25px">燒嘴的結(jié)構(gòu)是兩個同心的套管，煤氣一般由內(nèi)套管流出，空氣自外套管流出。廣東燒嘴</p><p style="text-indent:25px">再來說一下千瓦的概念，早期它是作為電的功率單位，后來延伸到了整個物理領(lǐng)域功率的單位。在單位換算中1KW=1000W，1W的定義是1J/s，相對應(yīng)的1KW=1000J/s=3600KJ/h，到這里再來看一下熱負荷的概念，就不難想明白燒嘴中熱負荷和千瓦的聯(lián)系了。焦耳作為國際通用單位在全世界都在使用，致誠熱能經(jīng)常碰到一些老工程師些喜歡使用卡作為能量單位，所以有些工程師提高燒嘴的功率時經(jīng)常說多少多少大卡的設(shè)備。也有直接說單位時間燒嘴的耗氣量的，這種表達一般都能理解。如以230KW天然氣燒嘴為例，它的熱負荷是230KW，即每小時熱負荷82.8萬千焦熱量，用大卡的單位表示是每小時約20萬大卡熱量，相應(yīng)的每小時消耗的天然氣約23立方。了解完這些，對燃燒器功率單位方面的問題應(yīng)該就能解決了，再進行設(shè)備選型及咨詢時不至于一頭霧水了。廣東燒嘴</p><p
