導(dao)熱(re)油(you)(you)(you)加熱(re)器的也叫有機(ji)熱(re)載體(ti)爐，俗稱(cheng)導(dao)熱(re)油(you)(you)(you)爐鍋(guo)爐，官(guan)方名(ming)稱(cheng)為熱(re)油(you)(you)(you)爐。其是以(yi)煤、油(you)(you)(you)、氣(qi)為燃料，以(yi)導(dao)熱(re)油(you)(you)(you)爐為循環(huan)介(jie)質供熱(re)的新(xin)型熱(re)能設備，導(dao)熱(re)油(you)(you)(you)爐指載熱(re)工質為高溫導(dao)熱(re)油(you)(you)(you)爐（也稱(cheng)熱(re)煤體(ti)、熱(re)載體(ti)）的新(xin)型熱(re)能轉換設備，通常也用(yong)“MW”（兆瓦）表示(shi)爐的容量，舊單位也用(yong)“萬千(qian)瓦/時”或“萬大卡/時”，即(ji)“104kcal/h”表示(shi)，導(dao)熱(re)油(you)(you)(you)爐的優勢在于“高溫低壓“、運行平穩而被廣泛運用(yong)。

導(dao)熱(re)(re)(re)(re)油爐(lu)的原理(li)：是(shi)以煤、重油、輕(qing)油、可(ke)燃(ran)氣體(ti)其他可(ke)燃(ran)材料為(wei)(wei)燃(ran)料，導(dao)熱(re)(re)(re)(re)油爐(lu)為(wei)(wei)熱(re)(re)(re)(re)載(zai)體(ti)。利用循(xun)環油泵強(qiang)制(zhi)液相循(xun)環，將熱(re)(re)(re)(re)能輸送給用熱(re)(re)(re)(re)設(she)備后，繼(ji)而返回重新(xin)加熱(re)(re)(re)(re)的直流(liu)式特種(zhong)工(gong)(gong)業爐(lu)。廣泛用于如石(shi)化、紡(fang)織、印染、塑(su)料、橡(xiang)膠、食(shi)品加工(gong)(gong)、木材加工(gong)(gong)、瀝青加熱(re)(re)(re)(re)、紙箱生產(chan)、蔬菜脫(tuo)水(shui)、烤漆、鑄造砂(sha)模烘干等。導(dao)熱(re)(re)(re)(re)油爐(lu)是(shi)一種(zhong)以熱(re)(re)(re)(re)傳導(dao)液為(wei)(wei)加熱(re)(re)(re)(re)介質的新(xin)型特種(zhong)鍋爐(lu)。具(ju)有低壓高溫工(gong)(gong)作特性。隨著工(gong)(gong)業生產(chan)的發(fa)展和科學技術的進(jin)步，導(dao)熱(re)(re)(re)(re)油爐(lu)得到了不斷(duan)的發(fa)展和應用。
