style="text-indent:25px">當(dāng)換熱器用于制程操作時(shí)，使用過(guò)熱蒸汽由于低的傳熱系數(shù)而降低效率，使用飽和蒸汽更加適合。另外當(dāng)高壓的干飽和蒸汽減壓至低壓時(shí)，在下游出口會(huì)產(chǎn)生過(guò)熱度。這樣都需要將過(guò)熱的蒸汽降溫至所需的接近飽和的溫度，這就需要減溫器。在很多情況下需要對(duì)高壓過(guò)熱的蒸汽同時(shí)進(jìn)行減溫和減壓。減溫減壓裝置是節(jié)能環(huán)保產(chǎn)品。減溫減壓裝置配上相應(yīng)的工業(yè)自動(dòng)化儀表（即熱控柜），可對(duì)電站或工業(yè)鍋爐及熱電廠等處輸送來(lái)的一次（新）蒸汽壓力P1、溫度T1進(jìn)行減溫減壓，使其二次蒸汽壓力P2、溫度T2達(dá)到生產(chǎn)工藝所需的要求。用于熱電廠、集中供熱、食品工業(yè)、石化工業(yè)、紡織工業(yè)、橡膠工業(yè)、造紙和紙漿工業(yè)和制藥等其它很多行業(yè)。崇明區(qū)減溫減壓裝置工作原理</p></p><br
