style="text-indent:25px">工業(yè)爐脈沖燃燒控制的優(yōu)勢：脈沖燃燒則不然，無論在何種情況下，燒嘴只有兩種工作狀態(tài)，一種是滿負荷工作，另一種是不工作，只是通過調(diào)整兩種狀態(tài)的時間比進行溫度調(diào)節(jié)，所以采用脈沖燃燒可彌補燒嘴調(diào)節(jié)比低的缺陷，需要低溫控制時仍能保證燒嘴工作在較佳燃燒狀態(tài)。在使用高速燒嘴時，燃氣噴出速度快，使周圍形成負壓，將大量窯內(nèi)煙氣吸人主燃氣內(nèi)，進行充分攪拌混合，延長了煙氣在窯內(nèi)的滯流時間，增加了煙氣與制品的接觸時間，從而提高了對流傳熱效率，另外，窯內(nèi)煙氣與燃氣充分攪拌混合，使燃氣溫度與窯內(nèi)煙氣溫度接近，提高窯內(nèi)溫度場的均勻性，減少高溫燃氣對被加熱體的直接熱沖擊。</p><p style="text-indent:25px">工業(yè)爐脈沖燃燒控制的優(yōu)勢：脈沖燃燒控制采用的是一種間斷燃燒的方式，使用脈寬調(diào)制技術(shù)，通過調(diào)節(jié)燃燒時間的占空比（通斷比）實現(xiàn)窯爐的溫度控制。燃料流量可通過壓力調(diào)整預(yù)先設(shè)定，燒嘴一旦工作，就處于滿負荷狀態(tài)，保證燒嘴燃燒時的燃氣出口速度不變。當(dāng)需要升溫時，燒嘴燃燒時間加長，間斷時間減?。恍枰禍貢r，燒嘴燃燒時間減小，間斷時間加長。脈沖燃燒控制的主要優(yōu)點為傳熱效率高，降低能耗?？商岣郀t內(nèi)溫度場的均勻性。無需在線調(diào)整，即可實現(xiàn)燃燒氣氛的精確控制?？商岣邿斓呢摵烧{(diào)節(jié)比。系統(tǒng)簡單可靠，造價低。減少NOx的生成。普通燒嘴的調(diào)節(jié)比一般為1：4左右，當(dāng)燒嘴在滿負荷工作時，燃氣流速、火焰形狀、熱效率均可達到較佳狀態(tài)，但當(dāng)燒嘴流量接近其較小流量時，熱負荷較小，燃氣流速降低，火焰形狀達不到要求，熱效率急劇下降，高速燒嘴工作在滿負荷流量50%以下時，上述各項指標(biāo)距設(shè)計要求就有了較大的差距。工業(yè)爐的環(huán)保等級是否滿足國家的需要，如果不滿足估計的需要，是不能審核通過的。</p><div

style="text-indent:25px">工業(yè)爐液體燃料燃燒裝置：通常稱油嘴，或噴嘴。燃料油需要經(jīng)過霧化后再燃燒，因此油嘴除具有一般燃燒裝置的基本性能外，還應(yīng)具有良好的霧化能力，以保證燃料的完全燃燒。根據(jù)霧化方法，油嘴可分為低壓油嘴、高壓油嘴、機械油嘴和轉(zhuǎn)杯油嘴，其中低壓油嘴和高壓油嘴應(yīng)用較廣。低壓油嘴是用全部助燃空氣作為霧化介質(zhì)，靠氣流的動量將油霧化，霧化粒徑80～100微米,空氣壓力一般為2940～7840帕，燃燒時的火焰一般為 600～1400毫米。高壓油嘴是用蒸汽或壓縮空氣作霧化介質(zhì)，壓力一般高達(3～12)×105帕，由于霧化介質(zhì)壓力高，噴出速度能達到或超過聲速，所以高壓油嘴的霧化能力比低壓油嘴強，霧化粒徑可達20～30微米，但需要附加一條輸送助燃空氣用的通道和相應(yīng)的氣流導(dǎo)向設(shè)施。工業(yè)爐具備要求：操作簡單，機械化、自動化程度較高，環(huán)境污染少，勞動條件好。重慶工業(yè)爐安裝多少錢</p><p
