3、考慮經(jīng)濟(jì)價(jià)值，維修成本及操作工人的素質(zhì)水平等。多方面的因素共同影響控制器的選型，在注重經(jīng)濟(jì)價(jià)值的同時(shí)也需要考慮使用價(jià)值。新型點(diǎn)火器結(jié)構(gòu)特點(diǎn)：耐火內(nèi)襯采用預(yù)制塊結(jié)構(gòu)、無(wú)水冷結(jié)構(gòu)；爐體鋼結(jié)構(gòu)采用分段、組合框架、滾輪行走結(jié)構(gòu)；爐前管道與點(diǎn)火爐燒嘴采用鋼管硬連接結(jié)構(gòu)，爐前煤氣管道設(shè)雙球閥。其拋棄耐材澆筑后逐步升溫烘爐工藝，采用預(yù)制組裝邊生產(chǎn)邊烘爐新工藝，新型點(diǎn)火器前排10

目前燒嘴上配套的自動(dòng)點(diǎn)火控制器分為很多類(lèi)型，眾多類(lèi)型中各自有其適用的工況，各個(gè)型號(hào)本身不存在好壞之分，但選型不當(dāng)，可能導(dǎo)致無(wú)法正常工作，甚至導(dǎo)致整個(gè)系統(tǒng)紊亂，本文簡(jiǎn)單介紹點(diǎn)火控制器在選型配套上的常見(jiàn)問(wèn)題。燒嘴的自動(dòng)點(diǎn)火過(guò)程屬于一個(gè)簡(jiǎn)易閉環(huán)系統(tǒng)，以大科自動(dòng)點(diǎn)火控制系統(tǒng)來(lái)講分為控制分析系統(tǒng)、檢測(cè)系統(tǒng)、執(zhí)行系統(tǒng)?？刂品治鱿到y(tǒng)由控制器及火焰檢測(cè)器組成；檢測(cè)系統(tǒng)由離子針或火焰光敏探頭組成；執(zhí)行結(jié)構(gòu)由電動(dòng)閥門(mén)、點(diǎn)火線圈組成。不同的場(chǎng)合每個(gè)系統(tǒng)中的配件會(huì)有所不同，但基本配置都是大同小異的。</p><p style="text-indent:25px">其中一種由熱電偶和安全電磁閥組成。燃?xì)馊紵螅瑹犭娕嫉亩它c(diǎn)因在高溫火焰中而產(chǎn)生電動(dòng)勢(shì)，電動(dòng)勢(shì)通過(guò)導(dǎo)線加到安全電磁閥的線圈上，產(chǎn)生的吸力吸住電磁閥的銜鐵，使燃?xì)饨?jīng)氣閥持續(xù)流向噴嘴，維持燃燒。因熱電偶的電動(dòng)勢(shì)比較弱（幾毫伏），電流比較小（幾十毫安），所以產(chǎn)生的吸力有限，一般要在點(diǎn)火瞬間給銜鐵一個(gè)外力，使銜鐵被吸住。當(dāng)火焰意外熄滅，熱電偶的溫度降低，產(chǎn)生的電動(dòng)勢(shì)接近消失，電磁閥的吸力也減弱而無(wú)法吸住銜鐵，這樣銜鐵在彈簧作用下被釋放，頭部的橡膠塊堵住燃?xì)饪?，氣閥被關(guān)閉。出現(xiàn)燒嘴頻繁點(diǎn)火問(wèn)題主要原因是廠家提供的點(diǎn)火控制器穩(wěn)定性不好，但也不排除其他因素。</p><div

style="text-indent:25px">天然氣正逐步被應(yīng)用在工業(yè)窯爐上，雖然天然氣不是一種新生能源，但之前大規(guī)模的應(yīng)用在工業(yè)窯爐上并不普遍，這與很多方面原因有關(guān)。燒嘴作為天然氣窯爐上的燃燒裝置是必不可少的設(shè)備，隨著自動(dòng)化要求的提高，現(xiàn)在的燒嘴一般都帶有自動(dòng)點(diǎn)火系統(tǒng)，由于天然氣易燃易爆的特性，因點(diǎn)火系統(tǒng)失靈導(dǎo)致燃?xì)獗Q的危險(xiǎn)可能會(huì)發(fā)生，所以我們更應(yīng)該了解點(diǎn)火系統(tǒng)的特性。完整的點(diǎn)火系統(tǒng)基本的結(jié)構(gòu)是點(diǎn)火控制器和熄火保護(hù)裝置。燒嘴的點(diǎn)火控制器一般包括點(diǎn)火電極和點(diǎn)火器（內(nèi)配有變壓器也有的是外配型），通過(guò)變壓器后的電壓達(dá)10kv以上，點(diǎn)火電極對(duì)點(diǎn)火柱高壓放電產(chǎn)生電火花來(lái)引燃天然氣。點(diǎn)火控制器的高溫模式是將火焰監(jiān)測(cè)回路脫開(kāi)，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。湛江點(diǎn)火器工廠</p><p style="text-indent:25px">一般燒嘴都配備有點(diǎn)火控制器及通常所說(shuō)的火花塞。湛江點(diǎn)火器工廠</p><p style="text-indent:25px">電極是燒嘴點(diǎn)火中常用的設(shè)備，在更換電極或是初次使用燒嘴時(shí)，需要特別注意觀察火花間隙，過(guò)大過(guò)小都對(duì)成功點(diǎn)火不利。電極檢測(cè)火焰時(shí)一定要將控制器中的地線有效接地，否則可能導(dǎo)致檢測(cè)失敗。正確選擇點(diǎn)火控制器及點(diǎn)火高壓包非常重要，控制器應(yīng)選擇性能穩(wěn)定的設(shè)備，這樣可以降低點(diǎn)火失敗的頻率。無(wú)論任何類(lèi)型的燒嘴都有一個(gè)點(diǎn)火過(guò)程，由于對(duì)產(chǎn)品性能的不熟悉，或者不了解基本的點(diǎn)火操作流程，可能在燒嘴初期點(diǎn)火時(shí)遇到點(diǎn)火故障，這往往影響整個(gè)工程項(xiàng)目的進(jìn)度。湛江點(diǎn)火器工廠</p><p
