風道(dao)式電(dian)加熱器(qi)的(de)雙(shuang)重保(bao)護設計，使(shi)其(qi)設備運行過程中的(de)安全性能比較(jiao)好；另外(wai)恒溫器(qi)，熔(rong)斷器(qi)安裝在加熱器(qi)可用(yong)于控(kong)制空氣管(guan)道(dao)工(gong)作溫度，使(shi)得風道(dao)式電(dian)加熱器(qi)的(de)也能夠有范(fan)圍有了進一步的(de)擴大。

在風道式電加(jia)熱器系統的制作中，焊接(jie)是十分重要的步(bu)驟(zou)，吉(ji)林鍋爐電熱管(guan)，因為(wei)系統大部(bu)分是由管(guan)道進(jin)行輸送的，所以(yi)管(guan)道和管(guan)道間、管(guan)道和其(qi)他(ta)部(bu)件之間的連接(jie)，除了螺栓連接(jie)外(wai)就(jiu)是采(cai)用焊接(jie)的。

應用(yong)(yong)(yong)領域：氣體(ti)電(dian)加(jia)(jia)熱(re)(re)(re)器(qi)主(zhu)要(yao)(yao)(yao)是用(yong)(yong)(yong)來將(jiang)所需要(yao)(yao)(yao)的(de)空(kong)(kong)氣流從(cong)初(chu)始溫度(du)加(jia)(jia)熱(re)(re)(re)到(dao)所需要(yao)(yao)(yao)的(de)空(kong)(kong)氣溫度(du)，可(ke)達(da)850℃。已被(bei)廣泛的(de)應用(yong)(yong)(yong)到(dao)航(hang)空(kong)(kong)航(hang)天(tian)、工(gong)業、化工(gong)工(gong)業和高等院校(xiao)等許多(duo)科(ke)研生產試驗室。特別適合于自動控溫和大流量高溫聯合系統和附件試驗。氣體(ti)電(dian)加(jia)(jia)熱(re)(re)(re)器(qi)使用(yong)(yong)(yong)的(de)范(fan)圍寬(kuan)：可(ke)以對任何氣體(ti)加(jia)(jia)熱(re)(re)(re)，產生的(de)熱(re)(re)(re)空(kong)(kong)氣干燥無(wu)水份(fen)、無(wu)化學(xue)腐(fu)蝕性、無(wu)污染、不(bu)導電(dian)、不(bu)燃(ran)燒、、被(bei)加(jia)(jia)熱(re)(re)(re)空(kong)(kong)間升溫快(可(ke)控)。

利用紅外線輻射(she)物(wu)體(ti)，物(wu)體(ti)吸收(shou)紅外線后，將輻射(she)能(neng)轉(zhuan)變為熱(re)能(neng)而被加熱(re)。

紅(hong)(hong)外(wai)(wai)線(xian)(xian)是一種電磁波(bo)。在(zai)(zai)(zai)太陽(yang)光(guang)譜中(zhong)(zhong)(zhong)，鍋(guo)爐電熱管(guan)價(jia)格，處在(zai)(zai)(zai)可見光(guang)的(de)紅(hong)(hong)端以外(wai)(wai)，鍋(guo)爐電熱管(guan)批發，是一種看不見的(de)輻射能(neng)。在(zai)(zai)(zai)電磁波(bo)譜中(zhong)(zhong)(zhong)，紅(hong)(hong)外(wai)(wai)線(xian)(xian)的(de)波(bo)長范(fan)圍在(zai)(zai)(zai)0.75～1000微(wei)(wei)米(mi)(mi)之間，鍋(guo)爐電熱管(guan)采(cai)購，頻率范(fan)圍在(zai)(zai)(zai)3×10～4×10赫之間。在(zai)(zai)(zai)工業應用中(zhong)(zhong)(zhong)，常將紅(hong)(hong)外(wai)(wai)光(guang)譜劃分為(wei)(wei)幾個波(bo)段：0.75～3.0微(wei)(wei)米(mi)(mi)為(wei)(wei)近紅(hong)(hong)外(wai)(wai)線(xian)(xian)區(qu)；3.0～6.0微(wei)(wei)米(mi)(mi)為(wei)(wei)中(zhong)(zhong)(zhong)紅(hong)(hong)外(wai)(wai)線(xian)(xian)區(qu)；6.0～15.0微(wei)(wei)米(mi)(mi)為(wei)(wei)遠紅(hong)(hong)外(wai)(wai)線(xian)(xian)區(qu)；15.0～1000微(wei)(wei)米(mi)(mi)為(wei)(wei)極遠紅(hong)(hong)外(wai)(wai)線(xian)(xian)區(qu)。不同(tong)物(wu)體(ti)對紅(hong)(hong)外(wai)(wai)線(xian)(xian)吸(xi)收的(de)能(neng)力不同(tong)，即使(shi)同(tong)一物(wu)體(ti)，對不同(tong)波(bo)長的(de)紅(hong)(hong)外(wai)(wai)線(xian)(xian)吸(xi)收的(de)能(neng)力也不一樣。
