Iyo boiler yekutanga kumhanya inodzorwa sei? Sei kutadza kuwedzera kukurumidza kukurumidza kukurumidza?
Dzvinyiriro inowedzera kukurumidza padanho rekutanga rekutanga boiler-up uye panguva yese yekutanga-up process inofanirwa kunonoka, kunyangwe, uye yakanyatso kudzorwa mukati meiyo yakatarwa. Kune yekutanga maitiro e-high-pressure uye ultra-high-pressure steam drum boilers, iyo yekumanikidza kuwedzera kumhanya inowanzodzorwa kuve 0.02 ~ 0.03 MPa/min; kune kunze kwenyika 300MW mayunitsi, iyo yekumanikidza kuwedzera kumhanya haifanire kunge yakakura kupfuura 0.07MPa/min pamberi pegidhi yekubatanidza, uye haifanirwe kunge yakakura kupfuura 0.07 MPa/min mushure mekubatanidza grid. 0.13MPa/min.
Muchikamu chekutanga chekusimudzira, nokuti zvishoma chete zvinopisa zvinoiswa mukushanda, kupisa hakuna simba, murazvo wechoto hauna kunyatsozadzwa, uye kupisa kwemhepo inopisa inopisa haina kuenzana; kune rumwe rutivi, nokuti tembiricha yekudziya kwepamusoro uye madziro echoto yakaderera kwazvo, Naizvozvo, pakati pekupisa kunoburitswa nekupisa kwemafuta, hapana kupisa kwakawanda kunoshandiswa kufambisa mvura yevira. Iyo yakadzikira kudzvanywa, ndiko kukura kwakadzikama kupisa kwemhupo, saka hapana chiutsi chakawanda chinogadzirwa pane evaporation pamusoro. Kutenderera kwemvura hakugadzirwe zvakajairika, uye kupisa hakugone kusimudzirwa kubva mukati. Nzvimbo yacho inopisa zvakaenzana. Nenzira iyi, zviri nyore kukonzera kushushikana kwakanyanya kwemafuta mumidziyo yekubuda, kunyanya dhiramu rehutsi. Nokudaro, kuwedzera kwekushisa kunofanira kunonoka pakutanga kwekuwedzera kwekumanikidza.
Mukuwedzera, maererano nekuchinja pakati pekushisa kwekuzara uye kumanikidzwa kwemvura uye mhepo, zvinogona kuonekwa kuti iyo yakakwirira kudzvinyirira, kuduku kukosha kwekupisa kwekupisa kunoshanduka nekumanikidzwa; iyo yakaderera kudzvinyirira, iyo yakakura kukosha kwekushisa kwesaturation kushanduka nekumanikidzwa, nokudaro zvichikonzera kusiyana kwekushisa Kunyanya kupisa kunetseka kuchaitika. Saka kudzivirira mamiriro ezvinhu aya, nguva yekuwedzera inofanira kunge yakareba.
Muchikamu chekupedzisira chekuwedzera kwekumanikidza, kunyangwe mutsauko wekushisa pakati pekumusoro nepasi madziro edhiramu uye emukati nekunze madziro akaderedzwa zvakanyanya, iyo yekumanikidza kuwedzera kukurumidza inogona kukurumidza kupfuura iyo yakaderera nhanho yekumanikidza, asi iyo mechanic. kushushikana kunokonzerwa nekuwedzera kwekushanda kwekushanda kwakakura, saka kumanikidzika mumashure ekupedzisira Kuwedzera kwekukurumidza hakufaniri kudarika kukurumidza kunotaurwa mumitemo.
Zvinogona kuoneka kubva pane zviri pamusoro apa kuti panguva yeboiler pressure yekusimudzira maitiro, kana iyo yekumanikidza inosimudzira kumhanya ichimhanya zvakanyanya, inokanganisa kuchengetedzeka kwedhiramu reutsi uye zvinhu zvakasiyana-siyana, saka iyo yekumanikidza inowedzera kumhanya haigone kukurumidza.
Ndedzipi nyaya dzinofanirwa kutariswa kana iyo unit inotanga kupisa uye kumanikidza?
(1) Mushure mekunge bhailer yabatidzwa, kuvhuvhuta soot kwemhepo preheater kunofanirwa kusimbiswa.
(2) Nyatsodzora kukwira kwetembiricha uye kukurumidza kusimuka zvinoenderana neyuniti yekutanga curve, uye tarisa musiyano wetembiricha pakati pemadhiramu epamusoro neakadzika uye madziro emukati nekunze kuti asapfuure 40°C.
(3) Kana iyo reheater yakatsva-yakapiswa, tembiricha yehutsi yekubuda muchoto inofanirwa kudzorwa zvakanyanya kuti isapfuure tembiricha inobvumidzwa yechubhu madziro, uye superheater uye reheater chubhu madziro anofanirwa kutariswa zvakanyanya kudzivirira kupisa.
(4) Nyatsotarisisa mwero wemvura yedhiramu uye vhura iyo economizer recirculation valve kana mvura yamiswa.
(5) Nyatsodzora kunaka kwezvinwiwa zvesoda.
(6) Vhara gonhi remhepo uye dhizavha yemhepo yemhepo panguva.
(7) Nguva dzose chengetedza moto wechoto uye pfuti yemafuta, simbisa kuchengetedza uye kugadziriswa kwepfuti yemafuta, uye kuchengetedza zvakanaka atomization uye kupisa.
8 Musiyano wetembiricha pakati pemativi maviri emupfuti wakapisa nemhepo inodziya zvakare haifanire kunge yakakura kupfuura 20°C. Shandisa mvura inopisa nekuchenjerera kudzivirira kuchinja kukuru mukupisa kweutsi.
(9) Gara uchitarisa uye nyora mirairo yekuwedzera yechikamu chimwe nechimwe kudzivirira kuvhiringidza.
(10) Kana kukanganisa kunowanikwa mumichina inobata zvakananga kushanda kwemaitiro, kukosha kunofanira kuziviswa, kuwedzera kwekumanikidza kunofanira kumira, uye kuwedzera kwekumanikidza kunofanira kuenderera mberi mushure mokunge zvikanganiso zvabviswa.
