了解蒸汽加熱器的(de)什么是間接加熱？間接加熱就是通過一種(zhong)稱為(wei)“換熱器”的(de)設備進行加熱的(de)方(fang)法。

蒸(zheng)汽(qi)(qi)從換熱(re)器(qi)壁表(biao)面流過，蒸(zheng)汽(qi)(qi)的(de)熱(re)量就轉移到被加熱(re)的(de)物(wu)質(zhi)一(yi)側(ce)。通(tong)過這種(zhong)方(fang)式，蒸(zheng)汽(qi)(qi)不會和被加熱(re)的(de)物(wu)質(zhi)接觸(chu)。典型的(de)使(shi)用蒸(zheng)汽(qi)(qi)加熱(re)的(de)換熱(re)器(qi)如(ru)夾套鍋、管加熱(re)、翅(chi)(chi)(chi)片(pian)式換熱(re)器(qi)（薄板翅(chi)(chi)(chi)片(pian)、空氣翅(chi)(chi)(chi)片(pian)）。這種(zhong)使(shi)用換熱(re)器(qi)進行加熱(re)的(de)方(fang)法不于使(shi)用蒸(zheng)汽(qi)(qi)作為熱(re)煤，其它(ta)的(de)熱(re)煤還包括熱(re)水或(huo)熱(re)油等(deng)。
