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?yàn)榭諝忸A(yù)熱器在轉(zhuǎn)動(dòng)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(yùn)行而使煙氣與空氣之間存在一定的間隙;同時(shí),由于煙氣和空氣之間存在壓差也會(huì)產(chǎn)生漏風(fēng)。對(duì)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(jī)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?yàn)檗D(zhuǎn)子上、下端溫度差異而發(fā)生蘑菇狀變形,進(jìn)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。</p><p>
