空氣預(yù)熱器漏風(fēng)主要可以分為以下兩類:(1)攜帶漏風(fēng)。攜帶漏風(fēng)主要是因為空氣預(yù)熱器在轉(zhuǎn)動過程中,一部分駐留在換熱元件中的空氣被攜帶到煙氣中去,一部分駐留在換熱元件中的煙氣被攜帶到空氣中去。這種情況造成的漏風(fēng)量很小,但這種漏風(fēng)是空氣預(yù)熱器的構(gòu)造無法避免的。(2)直接漏風(fēng)。直接漏風(fēng)主要是由于空氣預(yù)熱器結(jié)構(gòu)本身為保證安全運行而使煙氣與空氣之間存在一定的間隙;同時,由于煙氣和空氣之間存在壓差也會產(chǎn)生漏風(fēng)。對于三分倉空氣預(yù)熱器，它不但有空氣區(qū)與煙氣區(qū)之間的間隙漏風(fēng)，還有一次風(fēng)倉與二次風(fēng)倉之間漏風(fēng)。此外，外界的空氣也可以通過轉(zhuǎn)軸和機殼之間的間隙漏入煙氣區(qū)。直接漏風(fēng)主要包括徑向漏風(fēng)、軸向漏風(fēng)、環(huán)向漏風(fēng)。徑向漏風(fēng)占直接漏風(fēng)量的2/3左右,主要是因為轉(zhuǎn)子上、下端溫度差異而發(fā)生蘑菇狀變形,進而造成密封間隙的增大和漏風(fēng)率的增加；其次環(huán)向的密封間隙漏風(fēng)，**小的是軸向風(fēng)。在間隙及漏風(fēng)通流面積相同條件下冷端漏風(fēng)量較熱端大。為了減小漏風(fēng)，回轉(zhuǎn)式空氣預(yù)熱器均裝有密封裝置，主要有徑向密封、軸向密封、和環(huán)向密封。徑向密封：用以防止和減少空預(yù)器中空氣沿轉(zhuǎn)子的上、下端面通過徑向間隙漏到煙氣區(qū)的漏風(fēng)量。西藏空氣預(yù)熱器加盟板式空氣預(yù)熱器是全焊接密封結(jié)構(gòu)。</p><div

轉(zhuǎn)子隔倉由中心筒和外部分倉組成。轉(zhuǎn)子中心筒包括中心筒輪轂和內(nèi)部分倉，其中轉(zhuǎn)子主徑向隔板與中心筒輪轂連為一體。從中心筒向外延伸的主徑向隔板將轉(zhuǎn)子分為24倉，這些分倉又被二次徑向隔板分隔呈48倉。主徑向隔板和二次徑向隔板之間的環(huán)向隔板起加強轉(zhuǎn)子結(jié)構(gòu)和支撐換熱元件盒的作用。轉(zhuǎn)子與換熱元件等轉(zhuǎn)動件的全部重量由底部的球面滾子軸承支撐，而位于頂部的球面滾子導(dǎo)向軸承則用來承受徑向水平載荷。三分倉設(shè)計的空預(yù)器通過有三種不同的氣流，即煙氣、二次風(fēng)和一次風(fēng)。煙氣位于轉(zhuǎn)子的一側(cè)，而相對的另一側(cè)為二次風(fēng)側(cè)和一次風(fēng)側(cè)。上述三種氣流之間各由三組扇形板和軸向密封板相互隔開。煙氣和空氣流向相反，即煙氣向下、一次風(fēng)和二次風(fēng)向上。通過改變扇形板和軸向密封板的寬度可以實現(xiàn)雙密封和三密封，以滿足對空預(yù)器總漏風(fēng)率和一次風(fēng)漏風(fēng)率的要求。3、轉(zhuǎn)子外殼轉(zhuǎn)子外殼封閉轉(zhuǎn)子并構(gòu)成空預(yù)器的一部分，由低碳鋼板制成。轉(zhuǎn)子外殼由六個部分現(xiàn)場組裝而成正八面**于兩個端柱之間。端柱兩側(cè)的轉(zhuǎn)子外殼由四套鉸鏈側(cè)柱支撐在用戶鋼架上，鉸鏈側(cè)柱的布置角考慮到了轉(zhuǎn)子外殼和鉸鏈側(cè)柱能沿空預(yù)器中心向外自由、均勻膨脹。</p><p> 技術(shù)領(lǐng)域本實用新型涉及電站鍋爐空預(yù)器運行安全技術(shù)領(lǐng)域，特別涉及一種有效緩解空預(yù)器***氫銨堵塞的聯(lián)合系統(tǒng)。背景技術(shù)：目前，部分燃煤鍋爐排煙溫度低于設(shè)計值，導(dǎo)致空氣預(yù)熱器冷端綜合溫度降低、***氫銨腐蝕及堵塞加劇、煙氣余熱的能級降低、引風(fēng)機電耗增大等問題。尤其針對裝設(shè)有mggh系統(tǒng)的機組，單純利用空氣預(yù)熱器出口的煙氣余熱，不足以將脫硫塔出口的煙氣溫度提升至設(shè)計值，需另外投入大量的輔助蒸汽來維持煙囪入口煙氣溫度。（三）技術(shù)實現(xiàn)要素：本實用新型為了彌補現(xiàn)有技術(shù)的不足，提供了一種結(jié)構(gòu)簡單、設(shè)計合理的有效緩解空預(yù)器***氫銨堵塞的聯(lián)合系統(tǒng)。本實用新型是通過如下技術(shù)方案實現(xiàn)的：一種有效緩解空預(yù)器***氫銨堵塞的聯(lián)合系統(tǒng)，包括安裝在空氣預(yù)熱器出口至mggh煙氣冷卻器進口煙道之間的前置煙冷器，用來吸收煙氣余熱；安裝在送風(fēng)機出口冷風(fēng)道內(nèi)的蒸汽暖風(fēng)器，用來加熱鍋爐送風(fēng)；安裝在蒸汽暖風(fēng)器出口至空氣預(yù)熱器入口風(fēng)道之間的水媒式暖風(fēng)器，用來進一步提高鍋爐送風(fēng)溫度。本實用新型采用前置煙冷器聯(lián)合水媒式暖風(fēng)器和蒸汽暖風(fēng)器共同加熱鍋爐送風(fēng)。蒸汽暖風(fēng)器采用旋轉(zhuǎn)式，可根據(jù)環(huán)境溫度和機組負(fù)荷進行調(diào)整，減少風(fēng)機電耗。前置煙冷器回收部分煙氣余熱。板式空氣預(yù)熱器的作用是降低能源消耗。</p><div
