加熱管廠家介紹熱輻射管的加熱效率-上海雄雷環(huán)?？萍加邢薰?/title> <meta name="keywords" content="加熱管價格,加熱管批發(fā),加熱管制造商" /> <meta name="description" content="加熱管廠家介紹熱輻射管的加熱效率加熱爐的熱能一般采用天然氣等可燃氣體燃燒來提供，但是可燃氣體在燃燒的過程中產(chǎn)生的有害氣體會破壞爐內(nèi)熱處理所需要的環(huán)境，因此發(fā)明了輻射管使可燃氣體在輻射管內(nèi)燃燒，其熱能由輻射管輻射到爐內(nèi)，這樣有害氣體就不會破壞..." /> <link rel="shortcut icon"

16px;">加熱爐的熱能一般采用天然氣等可燃氣體燃燒來提供，但是可燃氣體在燃燒的過程中產(chǎn)生的有害氣體會破壞爐內(nèi)熱處理所需要的環(huán)境，因此發(fā)明了輻射管使可燃氣體在輻射管內(nèi)燃燒，其熱能由輻射管輻射到爐內(nèi)，這樣有害氣體就不會破壞爐內(nèi)環(huán)境。但是由于輻射管通過管壁輻射加熱工件，其加熱效率關(guān)系到熱處理的效率，因此輻射管的加熱效率是輻射管的主要特性之一。最早的輻射管是由德國在20 世紀(jì)30 年代發(fā)明并使用的，其結(jié)構(gòu)為單層直管式，水平或垂直穿過爐膛; 直到50 年代初U 型輻射管才問世; 為了提高提高輻射管的加熱效率，在U 型輻射管的基礎(chǔ)上發(fā)明了W 型輻射管; 隨著技術(shù)的進步又出現(xiàn)了P 型輻射管，輻射管的典型型式。為了進一步提高輻射管的加熱效率，在各種型號輻射管的基礎(chǔ)上又發(fā)明了麻面輻射管，其加熱面積比光面輻射管增加30%以上，大大提高了輻射管的加熱效率。這一過程基本上沿著兩條技術(shù)進化路線發(fā)展:</span></p><p style="line-height: 2em; text-indent: 2em; text-align:

曲線以提高輻射管的加熱效率，如將輻射管設(shè)計成波紋管。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">2) 表面形狀的進化路線:
