Ipayipi le-boiler
Amashubhu e-boiler angelinye lamapayipi angenamthungo.Izindlela zokukhiqiza ziyafana neshubhu engenamthungo, kodwa inezidingo eziqinile zokwenziwa kwamapayipi ensimbi.Ngokwezinga lokushisa, ishubhu le-boiler lihlukaniswe ngamashubhu abhayela ajwayelekile kanye neshubhu lebhayela elinomfutho omkhulu.
Izindlela zokukhiqiza:
① izinga lokushisa elivamile leshubhu likabhayela lingaphansi kuka-450 ℃, kusetshenziswa ipayipi eligoqwe elishisayo noma ipayipi elidonswa ngokubanda elikhiqiza ipayipi lensimbi.
② high-pressure boiler tube isetshenziswa kaningi ezimeni lokushisa eliphezulu kanye nepayipi lokucindezela okukhulu, umphumela we-high-temperature flue gas nomhwamuko wamanzi, i-oxidation nokugqwala.Ipayipi lensimbi elinamandla amakhulu okuphuka, ukumelana okuphezulu nokugqwala kwe-oxygen futhi libe nokuzinza okuhle kwenhlangano.
Izinhloso zamashubhu e-boiler:
① amashubhu abhayela ajwayelekile asetshenziswa kakhulu ukwenza amashubhu odongeni lwamanzi, amashubhu emanzini abilayo kanye nepayipi lesitimu esishisisa kakhulu, amashubhu kabhayela wesitimu esishisayo, ipayipi lentuthu elikhulu nelincane kanye nezitini ze-arch.
② ishubhu likabhayela elinomfutho ophezulu wengcindezi lisetshenziswa ikakhulukazi ukwenza umfutho ophezulu kanye namashubhu okushisa okushisa aphezulu, amashubhu okushisa kabusha, umzila womoya, ipayipi lesitimu esikhulu.
Isigaba:
Amashubhu e-boiler ajwayelekile kanye namashubhu kabhayela we-boiler onengcindezi ephezulu avezwa ekusebenzeni okuphezulu kwezinga lokushisa.Amashubhu e-boiler ngokuvamile, noma amashubhu okushisa okucindezelayo aphezulu ngokusho kokusetshenziswa kwawo angahlukaniswa abe amapayipi ensimbi ahlukahlukene.
Amazinga kanye nempahla yepayipi lensimbi iyatholakala ku-carbon, i-alloy, nensimbi engagqwali.
