Chii chinonzi boiler yakaderera tembiricha corroson?
Sulfac acid Corrosion iyo inoitika pane kumashure kwekudziya kweiyo boiler Mushure mekudziya-tembiricha corrosurs mune iyo Economizer tube, kubhururuka kunogona kuitika mukati menguva pfupi yenguva, kutumira njodzi dzekuchengetedza. Kuvharira vira yekugadziriswa kuchikonzera zvakare kurasikirwa kwehupfumi.
Chikonzero chikuru chekudziya-tembiricha corros of boilers
Sarufa muMafuta inopiswa kuti aumbe Sulfur dioxide (s + 02 = so2). Iyo sarufa dioxide inoenderera mberi oxidized pasi pechiitiko cheCATALYST kuumba Sulfuli Trioxide (2So2 + 02 = 2S03). So3 uye iyo Mvura Vapori mune flue gasi gadzira sulfutic acid vapor (so3 + h2o = h2so4). Kuvapo kweSulfutic acid mupros zvakanyanya inowedzera iyo dova poindi yefesi gasi. Sezvo tembiricha yemhepo mumhepo preheater yakaderera, iyo flue gasi tembiricha mune chikamu chepamutemo hachisi chakakwirira, uye tembiricha yemadziro inowanzo kuve yakaderera pane iyo flue gasi dova dew. Nenzira iyi, sulfuric acid muprines ichakanda mapfumo pasi peyemhepo preheater, ichikonzera sulfutic acid corrosion. Kwakadzika-tembiricha kujairika kunowanzoitika muzvimedu zvekupedza, asi kana iyo sarufa inokatyamadza, iyo turbine yekushambadzira yakakwira.
Boiler yakaderera tembiricha corrostion kesi
Kambani inotenderera-kambani yemubhedha mubhedha yakaiswa mukushanda kwemari kwenguva isingasviki gore, uye mapepa mazhinji mune yepazasi yehupfumi pombi yakatambura nekutsvagira uye kubhururuka. Iyo boiler mafuta musanganiswa weiyo bituminous Coal uye sludge, iyo yehupfumi tube zvinhu ndeye 20 Simbi (GB / T 3087-2008), uye iyo Economizer Inlet tembiricha kazhinji yakadzika kupfuura zana ° C.
Zvikonzero zveSerforongwa uye kubhururuka kwehupfumi tube kwakaongororwa kuburikidza nekuongororwa kwezvinhu, ethylographic quewiser, uye kuongorora kweChinorita Iyo yekunze madziro ehupfumi tube inotambura kubva kune yakaderera-tembiricha corroson pasi peyakaderera-tembiricha yekushandisa uye acid corrosion panguva yekuvhara, iyo pakupedzisira inotungamira kuchengetedzwa kwemarasha. Iyo pombi yakagadziriswa, yakakora uye inodonha.
Yakadzika tembiricha corroson yekudzivirira matanho
1. Wedzera tembiricha yemadziro eyemhepo preheater tube kuitira kuti tembiricha yemadziro yakakwira kupfuura iyo flue gasi dew.
2. 3
4
5. Nekuona iyo acid dow ponto tembiricha, iyo acid dow pfambi iri pasi pemamwe mamiriro ekushanda anogona kunyatsozivikanwa, nekudaro achichinja tembiricha yekudziya kuti uwane mamiriro ekuchengetedza simba uye achiwedzera hupenyu hwemubhoti.
