style="text-indent:25px">工業(yè)爐可以采用的一些節(jié)能措施：（1）采用圓形爐膛替代箱形爐膛，可強(qiáng)化爐膛對工件均勻傳熱的效果，減少爐壁散熱量，使?fàn)t膛形成一個(gè)熱交換系統(tǒng)，在加熱元件，爐襯和工件3者之間進(jìn)行熱交換。通過采用合理的爐膛空間和在不增大爐膛空間容積的前提下，加大爐內(nèi)壁面積，以增大熱交換面積的方式提高爐膛熱交換從而提高熱效率。（2）在爐膛內(nèi)安設(shè)風(fēng)扇，加強(qiáng)爐內(nèi)對流傳熱。特別是小型加熱爐，高速氣流可破壞停滯在工件表面阻礙傳熱和界面反應(yīng)爐氣邊界底層，起到縮短加熱時(shí)間和加快提高工件溫度的作用。（3）爐體密封，包括爐膛內(nèi)各引出構(gòu)件，爐殼，爐門等處的密封。爐體密封不嚴(yán)，將會(huì)造成到處跑火、漏火，造成能源大量浪費(fèi)、設(shè)備燒壞、環(huán)境惡劣等狀況，因此爐體密封直接影響工件品質(zhì)和能耗，同時(shí)密封也是爐內(nèi)氣氛控制的關(guān)鍵。而耐火纖維制品的出現(xiàn)，為解決爐體密封創(chuàng)造了條件，實(shí)現(xiàn)了軟密封。</p><p style="text-indent:25px">工業(yè)爐的燃料消耗量、原材料的消耗總量、能源消耗量和產(chǎn)品質(zhì)量都影響著工業(yè)爐的質(zhì)量。燃燒系統(tǒng)自動(dòng)控制技術(shù)是工業(yè)爐運(yùn)行的中心技術(shù)。但由于很多原因，我國的工業(yè)爐大多存在投入高、能耗高的劣勢。在人工控制方面和燃燒自動(dòng)化控制技術(shù)與工業(yè)發(fā)達(dá)國家相比還是存在很大的差距。在很長一段時(shí)間內(nèi)，國內(nèi)的工業(yè)爐新技術(shù)依然處于開發(fā)研究階段，很多企業(yè)并不重視燃燒系統(tǒng)的研究，從而也就忽視了工業(yè)爐燃燒系統(tǒng)改造的關(guān)鍵技術(shù)。很多企業(yè)只是根據(jù)燃燒能力的需要來設(shè)計(jì)并生產(chǎn)工業(yè)爐，忽視了工業(yè)爐的研究和開發(fā)。工業(yè)爐的生產(chǎn)、運(yùn)行和控制將浪費(fèi)大量的人力物力。所以現(xiàn)階段我國的工業(yè)爐燃燒系統(tǒng)還有許多問題，不僅在爐的性能方面有待提高，有的還存在一定的安全生產(chǎn)隱患。工業(yè)爐的結(jié)構(gòu)和性能特點(diǎn)，一般都是按照客戶要求，為客戶設(shè)計(jì)制造的。</p><div

style="text-indent:25px">熱工檢測與控制：目前我國工業(yè)爐的能源消耗大，浪費(fèi)嚴(yán)重，普遍存在空氣過剩系數(shù)過大的問題，這主要是由于調(diào)節(jié)手段的落后，工人的勞動(dòng)強(qiáng)度較大，難以保證理想的燃燒工況。因此提高熱工檢測與控制水平，具有很大的節(jié)能潛力。采用先進(jìn)的自動(dòng)控制技術(shù)，特別是采用微機(jī)控制系統(tǒng)，已經(jīng)成為工業(yè)爐自動(dòng)控制的發(fā)展方向。通過設(shè)置自動(dòng)控制系統(tǒng)，以各相關(guān)系統(tǒng)的及時(shí)精確配合和控制來實(shí)現(xiàn)節(jié)能。諸如加熱爐各主要過程變量的定量控制，爐溫與燃料流量的串級控制，燃料與助燃空氣的比值控制以及煙道廢氣的含氧量控制等。能源管理：工業(yè)爐節(jié)能除了從設(shè)備和技術(shù)方面挖掘潛力外，還應(yīng)從能源管理方面人手。從組織、生產(chǎn)、操作3方面著手，加強(qiáng)能源管理工作。高效組織生產(chǎn)，加強(qiáng)設(shè)備維護(hù)，發(fā)揮設(shè)備的能力，使?fàn)t子高效運(yùn)行。提高操作水平，加強(qiáng)計(jì)劃調(diào)度，并對能源使用過程中造成的跑、冒、滴、漏等能源浪費(fèi)現(xiàn)象進(jìn)行檢查和處理，有效杜絕各種有形損失。在工業(yè)爐循環(huán)操作過程中，及時(shí)調(diào)整熱負(fù)荷，對于工業(yè)爐正常工作具有重要的影響。北京工業(yè)爐價(jià)格</p><p style="text-indent:25px">在工業(yè)爐上裝設(shè)預(yù)熱器以后，由于回收了熱量，可以節(jié)約燃料并易于提高爐溫以加快升溫速度。上海小型工業(yè)爐供應(yīng)</p><p style="text-indent:25px">市場上的工業(yè)爐盡管應(yīng)用的行業(yè)普遍，種類繁多，但它們還是有許多相同之處，下面我們就來研究一下具體有哪些。 1、熱工的基礎(chǔ)理論相同，均以熱力學(xué)幾大定律為基礎(chǔ)。燃料燃燒、氣體流動(dòng)和爐內(nèi)傳熱過程基本相同。 2、基本組成部分雷同，不論何種爐子，一般均由以下幾個(gè)部分組成： ① 產(chǎn)生熱能裝置部分(如燃燒室、燒嘴、電熱元件等)。 ② 放置物料部分(如爐膛、爐缸、臺(tái)車等)。 ③ 排煙系統(tǒng)(對于燃料爐要有煙道、煙囪等)。 ④ 輔助裝置(如爐門、預(yù)熱器、輸送鏈等)。 3、熱效率低，耗能大。工業(yè)爐是工業(yè)生產(chǎn)中的主要用能設(shè)備，每年耗一次能源約占全國總能耗的1/4。尤其在冶金、機(jī)電等企業(yè)的熱加工生產(chǎn)中，爐子耗能約占工序能耗的70%以上，是生產(chǎn)中的較大用能戶。上海小型工業(yè)爐供應(yīng)</p></p><br /><p>文章來源地址:
