正常輸(shu)送狀態下(xia)，隨著輸(shu)送管(guan)(guan)道(dao)距離的(de)(de)增(zeng)長，物(wu)(wu)(wu)料(liao)紊流(liu)流(liu)動狀態被(bei)破(po)壞，并積(ji)聚(ju)于管(guan)(guan)道(dao)底(di)面，雙(shuang)套(tao)管(guan)(guan)母管(guan)(guan)因物(wu)(wu)(wu)料(liao)發(fa)生積(ji)聚(ju)而趨(qu)于堵(du)管(guan)(guan)，局部壓阻增(zeng)加，產生局部高(gao)氣(qi)壓，使得(de)旁(pang)路(lu)進入雙(shuang)套(tao)管(guan)(guan)內(nei)助(zhu)推(tui)管(guan)(guan)的(de)(de)空氣(qi)流(liu)量增(zeng)加，在(zai)飛(fei)灰堆前后(hou)開口處，形成更強的(de)(de)紊流(liu)，從而疏松堆積(ji)的(de)(de)飛(fei)灰堆，消除堵(du)塞。這樣料(liao)段不斷分割(ge)、移動、吹散，將(jiang)(jiang)物(wu)(wu)(wu)料(liao)不斷向前輸(shu)送。雙(shuang)套(tao)管(guan)(guan)濃相正壓氣(qi)力(li)輸(shu)送系統的(de)(de)輸(shu)送機(ji)理基于一個非(fei)常簡單的(de)(de)物(wu)(wu)(wu)理原理實現(xian)：空氣(qi)將(jiang)(jiang)向阻力(li)小的(de)(de)方(fang)向流(liu)動。發(fa)電廠輸(shu)灰管(guan)(guan)道(dao)氣(qi)力(li)雙(shuang)套(tao)管(guan)(guan)，雙(shuang)套(tao)管(guan)(guan)氣(qi)力(li)輸(shu)灰管(guan)(guan)道(dao)
