在使用一些爐溫較高的高溫設(shè)備時(shí)，控制器對(duì)火焰的監(jiān)測(cè)可能會(huì)受到這樣那樣的影響，比如：火焰監(jiān)測(cè)器接收到由爐壁反射來(lái)的紫外光而非來(lái)自所監(jiān)測(cè)燒嘴的火焰。從而導(dǎo)致系統(tǒng)誤判，影響系統(tǒng)正常運(yùn)行。 </p> <p> 所以，為了解決這個(gè)問(wèn)題，高溫模式因此誕生！ </p> <p> <p> 高溫模式工作原理：<span style="font-size:12px;">燒嘴控制器的高溫模式是將火焰監(jiān)測(cè)回路脫開，而不再對(duì)火焰進(jìn)行實(shí)時(shí)監(jiān)測(cè)的一種工作方式。</span> </p> <p> 這種操作模式的先決條件是必須要有其他手段（如溫度監(jiān)測(cè)）來(lái)確保爐膛內(nèi)火焰的存在。 </p> <p> 這種工作方式使得燒嘴控制器避免了干擾，減少誤判，高溫下保持穩(wěn)定工作。 </p> <p> <br /> </p> <p> <br /> </p>

style="text-indent:25px">燒嘴也叫燃燒器，是工業(yè)燃料爐上用的燃燒裝置的俗稱，可理解為“燒火的噴嘴”的簡(jiǎn)稱。通常指的是燃燒裝置本體部分，有燃料入口、空氣入口和噴出孔，起到分配燃料和助燃空氣并以一定方式噴出后燃燒的作用。燒嘴磚是燃燒裝置的重要組成部分。燒嘴磚的作用有： 1）將燃料在燒嘴磚內(nèi)加熱至著火溫度，使其易于點(diǎn)火并迅速燃燒。 2）在燒嘴磚內(nèi)保持一定的高溫，使燃燒過(guò)程穩(wěn)定，避免產(chǎn)生脈動(dòng)或燃燒中斷現(xiàn)象。 3）組織火焰形狀，滿足加熱工藝的要求。 4）使燃料和空氣進(jìn)一步混合。燒嘴按所用材質(zhì)分為：鉻剛玉質(zhì)燒嘴磚，剛玉莫來(lái)石燒嘴磚，高鋁莫來(lái)石燒嘴磚，粘土質(zhì)燒嘴磚，碳化硅燒嘴磚。</p><p style="text-indent:25px">碳化硅是一種單相、無(wú)壓燒結(jié)碳化硅陶瓷，西安碳化硅燒嘴，具有高純度、細(xì)晶和極低氣孔率等優(yōu)良特性。可以作為石墨、不銹鋼、金屬鉭、哈氏金、氟塑料和其他傳統(tǒng)材料的比較好替代品。在化工、冶金等行業(yè)的高溫、高壓、強(qiáng)腐蝕、高磨損的極端環(huán)境中。高性能碳化硅換熱器具有碳化硅陶瓷的**度、耐高溫、高導(dǎo)熱和面的耐酸堿腐蝕特性，特別適用于高溫、高壓、強(qiáng)酸強(qiáng)堿腐蝕、高速氣流沖刷、顆粒磨損等苛刻工況條件。其優(yōu)良的熱交換效率可滿足節(jié)能減排和環(huán)保的迫切需求。低壓天然氣燒嘴：天然氣壓力在5kpa以下。</p><div

壓力霧化燒嘴壓力霧化燒嘴是靠燃油自身的壓力轉(zhuǎn)化為噴射動(dòng)能，通過(guò)液膜或液柱受空氣的剪切擾動(dòng)而使燃油霧化。這種燒嘴的優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單、運(yùn)行成本低。缺點(diǎn)是當(dāng)負(fù)荷變小時(shí)霧化顆粒度及平均尺寸迅速增加燃燒效率降低且小流量燒嘴易堵賽和結(jié)焦。 1.1.2 機(jī)械霧化燒嘴機(jī)械霧化燒嘴是將燃油的機(jī)械能轉(zhuǎn)化為霧化能量，常見(jiàn)機(jī)械霧化燒嘴是轉(zhuǎn)杯式霧化燒嘴。此類燒嘴對(duì)機(jī)械能要求較高，一般要求非常高的轉(zhuǎn)速才能霧化所需的剪切力。 1.1.3 氣動(dòng)霧化燒嘴氣動(dòng)霧化燒嘴是利用空氣或蒸氣的高速運(yùn)動(dòng)對(duì)液膜或液柱進(jìn)行撞擊、剪切、旋轉(zhuǎn)。氣液兩相產(chǎn)生相對(duì)高的相對(duì)速度來(lái)實(shí)現(xiàn)破碎霧化。氣動(dòng)霧化燒嘴的優(yōu)點(diǎn)是調(diào)節(jié)范圍廣、霧化性能好。特征是燒嘴出口采用了喇叭口形狀的燒嘴磚(見(jiàn)圖)，使火焰形成厚100~200mn 直徑600- 2000mm 的貼壁圓盤形火焰。碳化硅燒嘴廠商哪家好</p><p style="text-indent:25px">鍋爐點(diǎn)火燒嘴的工作條件比較惡劣，長(zhǎng)期受爐膛高溫輻射和火焰沖刷，容易造成蠕變、高溫變形和損壞。四川工業(yè)燒嘴怎么樣</p><p style="text-indent:25px"> 再來(lái)說(shuō)一下千瓦的概念，早期它是作為電的功率單位，后來(lái)延伸到了整個(gè)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(duì)應(yīng)的1KW=1000J/s=3600KJ/h，到這里再來(lái)看一下熱負(fù)荷的概念，就不難想明白燒嘴中熱負(fù)荷和千瓦的聯(lián)系了。焦耳作為國(guó)際通用單位在全世界都在使用，致誠(chéng)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(shí)經(jīng)常說(shuō)多少多少大卡的設(shè)備。也有直接說(shuō)單位時(shí)間燒嘴的耗氣量的，這種表達(dá)一般都能理解。如以230KW天然氣燒嘴為例，它的熱負(fù)荷是230KW，即每小時(shí)熱負(fù)荷82.8萬(wàn)千焦熱量，用大卡的單位表示是每小時(shí)約20萬(wàn)大卡熱量，相應(yīng)的每小時(shí)消耗的天然氣約23立方。了解完這些，對(duì)燃燒器功率單位方面的問(wèn)題應(yīng)該就能解決了，再進(jìn)行設(shè)備選型及咨詢時(shí)不至于一頭霧水了。四川工業(yè)燒嘴怎么樣</p><p
