按照換熱器的工(gong)藝用途來分的話主要就是(shi)分為：板(ban)(ban)(ban)式(shi)(shi)加熱(re)器、板(ban)(ban)(ban)式(shi)(shi)冷卻器、板(ban)(ban)(ban)式(shi)(shi)冷凝器、板(ban)(ban)(ban)式(shi)(shi)預(yu)熱(re)器。根據(ju)組合(he)流程來看是(shi)分為：單(dan)程板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器和多程板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器。當然了我們還可(ke)(ke)以根據(ju)兩種(zhong)介質的流動方向可(ke)(ke)以分為：順流板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器、逆流板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器、交叉流板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器。如(ru)果按(an)照流道的堿洗的大小來分的話就可(ke)(ke)以分為常規間隙(xi)板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器和寬間隙(xi)板(ban)(ban)(ban)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)器了。

無頭除氧器是一臺典型的圓筒形臥式容器，內置噴頭、蒸汽分配裝置，貯存需求除氧的凝結水和排出已除氧的凝結水到鍋爐給水泵。高效換熱器采用滑壓運行方式,四段抽汽和輔汽兩路汽源,在四抽管路上只設防止汽輪機進水的截止閥和逆止門，不設調節閥，為滑壓運行；而輔汽供汽管路上設壓力調節閥，用于除氧器定壓運行時的壓力調節。換熱器汽源：除(chu)氧器(qi)的加熱蒸汽有兩(liang)路汽源，分別為四抽和輔(fu)汽.

管殼式換熱器(shell tube heat exchanger)又稱列管式換熱器。是以封閉在殼體中管束的壁面作為傳熱面的間壁式換熱器。這種高效換熱器結構較簡單，操作可靠，可用各種結構材料（主要是金屬材料）制造，能在高溫、高壓下使用，是目前應用zui廣的類型。管殼式換熱器由殼體、傳熱管束、管板、折流板（擋板）和管箱等部件組成。換熱器價格殼體(ti)(ti)(ti)多(duo)為(wei)(wei)圓筒(tong)形，內(nei)(nei)部(bu)裝有管(guan)(guan)束(shu)，管(guan)(guan)束(shu)兩端固定在(zai)管(guan)(guan)板(ban)上。進(jin)行換熱(re)的冷熱(re)兩種流體(ti)(ti)(ti)，一種在(zai)管(guan)(guan)內(nei)(nei)流動，稱為(wei)(wei)管(guan)(guan)程(cheng)流體(ti)(ti)(ti)；另一種在(zai)管(guan)(guan)外流動，稱為(wei)(wei)殼程(cheng)流體(ti)(ti)(ti)。為(wei)(wei)提高管(guan)(guan)外流體(ti)(ti)(ti)的傳熱(re)分系數，通常在(zai)殼體(ti)(ti)(ti)內(nei)(nei)安(an)裝若干擋板(ban)。

一、清洗類型。換熱器設備清洗主要有在線清洗和離線清洗兩種。在線清洗。在線清洗可以理解為就地清洗或稱為原位清洗，其定義為：不拆卸設備或元件，在密閉的條件下，用一定溫度和濃度的清洗液對清洗裝置加以強力作用，使換熱器設備的表面洗凈和殺菌的方法。優點是設備不用停機，不影響正常生產使用。缺點是換熱器價格清(qing)洗效果(guo)相對于離線清(qing)洗來說(shuo)還不是很好。若清(qing)洗時(shi)間(jian)較長(chang)，會影(ying)響設備(bei)運轉的穩定性。
