A: I-tail flue ye-steam generator izoba nezinkinga ezihlukahlukene ngemva kokusetshenziswa isikhathi eside, okusobala kakhulu umonakalo. Izizathu zokulahlekelwa kwendawo yokushisa ekugcineni komsila zihlaziywa ngokuningiliziwe ngezansi.
Umlotha kanye ne-slag engena ku-flue ekugcineni inobunzima obuthile ngenxa yokushisa kwayo okuphansi. Uma ikhishwa kanye nendawo yokushisa eyinhloko ye-flue gas, izodala umonakalo odongeni lwamapayipi. Ikakhulukazi emshinini wokushisisa ukushisa, izinga lokushisa legesi ye-flue endaweni yokungena liye lehla laya cishe ku-450 ° C, izinhlayiya zomlotha zinzima kakhulu, futhi ipayipi yensimbi yensimbi enobubanzi obuncane obuncane isetshenziswa, okungenzeka ukuthi yonakale.
Ngesikhathi esifanayo, umonakalo ungenye yezizathu zokuthi kungani i-heat exchanger iqhekeka i-akhawunti yengxenye ephezulu yezinkinga zokuqhekeka kwe-steam generator.
Uma kuqhathaniswa nokugeleza kodonga lwamapayipi, igesi ewuketshezi equkethe umlotha wezinhlayiyana eziqinile izodala umonakalo odongeni lwamapayipi, okubizwa ngokuthi ukugqwala kokuguguleka, okwaziwa nangokuthi ukuguguleka.
Kunezinhlobo ezimbili eziyisisekelo zokuguga okugugulekayo kanye nomonakalo womthelela. I-microscopic morphology yezinsimbi ezimbili ze-antifriction ayifani.
Ukulimala kokuguguleka ukuthi i-engeli yomthelela yezinhlayiya zothuli endaweni ehambisanayo yodonga lwamapayipi incane kakhulu, iseduze nokuhambisana. Izinhlayiya zomlotha zihlukaniswe nge-perpendicular ebusweni bodonga lwamapayipi, okwenza ukuba zifakwe odongeni lwamapayipi oluthintekayo, futhi amandla engxenye ye-intersection yezinhlayiya zomlotha kanye nodonga lwamapayipi kwenza izinhlayiya zomlotha zigoqe eduze kwendawo yodonga lwamapayipi. i-tube wall. Indima yokusika ubuso. Uma udonga lwamapayipi lungakwazi ukumelana nesenzo sokusika samandla omphumela, kuzoba nezinhlayiya zensimbi ezikhishwe emzimbeni wepayipi futhi zinciphise. Ngaphansi kwesenzo sokusika esiphindaphindiwe senani elikhulu lomlotha, ubuso bodonga lwamapayipi buzolimala.
Ukulimala komthelela kusho ukuthi i-engeli yomthelela phakathi kwezinhlayiya zothuli kanye nobuso bodonga lwamapayipi bukhulu ngokuqhathaniswa, noma eduze nokuma mpo, futhi ingaphezulu lodonga lwamapayipi lufakwe ngesivinini esihambisanayo sokunyakaza, ukuze udonga lwamapayipi angaphezulu lwenze izinguquko zomumo omncane noma imifantu emincane. Ngaphansi komthelela ophindaphindiwe wesikhathi eside wenani elikhulu lezinhlayiya zothuli, isendlalelo esiyisicaba esine-denatured saxebuka kancane futhi sonakaliswa.
