A: Umsila womsila wejenereyitha yomphunga uya kuba neengxaki ezahlukeneyo emva kokusetyenziswa ixesha elide, owona monakalo ucacileyo. Izizathu zokulahleka kwendawo yokufudumala kumsila womsila zihlalutywa ngokubanzi ngezantsi.
Umlotha kunye ne-slag engena kwi-flue ekupheleni inobunzima obuthile ngenxa yokushisa kwayo okuphantsi. Xa ikhutshwe kunye ne-primary heat surface ye-flue gas, iya kubangela umonakalo eludongeni lombhobho. Ngokukodwa kwi-heat exchanger, ukushisa kwegesi ye-flue kwi-inlet kuye kwehla malunga ne-450 ° C, iinqununu zomlotha zinobunzima, kwaye umbhobho we-carbon steel owenziwe ngodonga oluncinci lusetyenziswa, olunokuthi lonakaliswe.
Kwangaxeshanye, umonakalo sesinye sezizathu zokuba i-akhawunti yokutshintshiselana kobushushu ibangela umlinganiselo omkhulu weengxaki zokuqhekeka kwe-steam generator ezine.
Xa kuthelekiswa nokuhamba kodonga lombhobho, i-flue gas equlethe uthuthu oluqinileyo luya kubangela umonakalo kudonga lombhobho, olubizwa ngokuba yi-rosion corrosion, eyaziwa ngokuba yi-rosion.
Kukho iintlobo ezimbini ezisisiseko zokunxitywa kwe-erosive kunye nomonakalo wempembelelo. I-morphology ye-microscopic ye-antifriction metals ezimbini ayifani.
Umonakalo wokhukuliseko kukuba i-engile yempembelelo yamasuntswana othuli kumphezulu wodonga lombhobho ohambelanayo incinci kakhulu, isondele kwi-parallel. Amasuntswana othuthu ahlukaniswe perpendicular kumphezulu wodonga lombhobho, ezenza ukuba zifakwe kudonga lombhobho ochaphazelekayo, kunye namandla ecandelo lokuhlangana kwamasuntswana othuthu kunye nomphezulu wodonga lombhobho wenza ukuba amasuntswana othuthu aqengqeleke ecaleni komphezulu wodonga lombhobho. ityhubhu eludongeni. Indima yokusika ubuso. Ukuba udonga lombhobho alukwazi ukumelana nesenzo sokusika samandla asiphumo, kuya kubakho iinqununu zetsimbi ezikhutshiweyo kumzimba wombhobho kwaye zincitshiswe. Ngaphantsi kwesenzo sokusika ngokuphindaphindiweyo kwexesha elide lomlotha, umphezulu wodonga lombhobho uya konakaliswa.
Umonakalo wempembelelo kuthetha ukuba i-angle yempembelelo phakathi kwamasuntswana othuli kunye nomphezulu wodonga lombhobho mkhulu kakhulu, okanye usondele ngokuthe nkqo, kwaye umphezulu wodonga lombhobho ufakwe kwisantya sokunyakaza esihambelanayo, ukwenzela ukuba udonga lombhobho womphezulu wenze utshintsho oluncinci lwemilo okanye iintanda ezincinci. Ngaphantsi kwempembelelo ephindaphindiweyo yexesha elide lenani elikhulu leengqungquthela zothuli, i-flat denatured layer yahlutha ngokukhawuleza kwaye yonakaliswa.
