Iri bepa rinounza tekinoroji nyowani yekupisa moto muindasitiri, uye tekinoroji inounza kuvandudzwa kwakakosha mukuchengetedza simba uye kuderedza kubuda.
Industrial furnaces inonyanya kukamurwa kuita smelting kukanda uye kupisa kurapwa muchoto mhando mbiri.Iyo yekutanga inoshandiswa pakunatsa uye kunyunguduka kukanda, nepo iyo yekupedzisira inoshandiswa pakudziya uye kupisa kurapwa kwemabhiriti isati yagadziriswa.Mafuta mazhinji anoshandiswa pakudziisa simbi igasi rechisikigo kana gasi remuguta, rinofanirwa kupihwa mumhepo nemhepo inofuridza kuti itsigire.Sezvatinoziva tose, mhepo inoumbwa nenitrogen, iyo inotora 78%, uye oksijeni, iyo inotora 21% (uye inenge 1% yemagasi akanaka).Nitrogen, iyo isina simba rinopisa, inova kudhonza, iyo isingangononoki kupisa kwekupisa, asiwo inobvisa kupisa mumhepo inopisa, kuwedzera kumatambudziko ezvakatipoteredza.Mushure memakore ekutsvagisa nekusimudzira, The Linde Group yekuGermany yakagadzira The low-temperature pure oxygen combustion technology (LTOF), iyo yakakodzera kunyungudusa, kunyunguduka kukanda uye kupisa kurapa kwesimbi dzisina-ferrous sesimbi, mhangura nealuminium.
- Kuunzwa kweyakadzika tembiricha yakachena okisijeni combustion tekinoroji (LTOF) muchoto cheindasitiri
Mhedzisiro mikuru yeiyo pure oxygen combustion tekinoroji ndeiyi:
(1) hapana nitrogen inopinda muchoto;
(2) hapana nitrogen inobvisa kupisa muflue gasi;
(3) kuwedzera kushanda kwemwaranzi kupisa kupisa;
(4) iyo flue gasi inogara kwenguva yakareba muchoto, kuitira kuti ivandudze kupisa kwekuita;
(5) sezvo pasina nitrogen mukupisa inotsigira gasi, haina kukanganisa pakuchengetedza kwezvakatipoteredza kana yaburitswa;
(6) iyo inopisa inotsigira mhedzisiro yeokisijeni yakachena inosvika 77%, nepo kupisa kwemhepo kunotsigira mwero ingori 23%.
- Zvakanakira zveyakadzika tembiricha yakachena okisijeni burner (LTOF) murazvo muchoto cheindasitiri
Chinangwa cheyakadzika tembiricha yakachena okisijeni combustion (LTOF) kuvandudza tekinoroji ndeyekuvandudza kugona kunyunguduka uye kugona kwekuratidzira.Iyo yakasarudzika LTOF burner inobvumira iyo flue gasi kubva muchoto chekupinza kupinda munzvimbo yekupisa yekupisa, ichidzikisa huwandu hweokisijeni kumberi kwemoto uye kudzikisa chiyero chekupisa, zvichikonzera kudzikira kwemoto tembiricha iri padyo nemurazvo. yekupisa kwemhepo-mafuta.Iyi LTOF yakachena okisijeni inopisa moto maitiro anoita kuti tembiricha muchoto iwedzere yunifomu, inobvisa nzvimbo dzinopisa dzemuno, kuderedza kushandiswa kwemafuta, kuderedza kuburitsa gasi nekuvandudza simbi yekudzoreredza.Kuenzanisa pakati pemhepo inopisa uye yakaderera-tembiricha yakachena okisijeni kupisa, pakati payo, kupisa kwemhepo, kupisa simba i311kW, kutonhora kwemvura ndeye 231kW, avhareji inogara ichiyerwa muakanyungudutswa aruminiyamu i1131 ℃, uye kupisa kunoyerera ndiko 79kW/m2.Low-temperature. kupisa kweokisijeni yakachena, simba rinopisa 257kW, kutonhora kwemvura 66kW, chiyero chinopfuurira chealuminium muvhareji inokosha ye1152 ℃, kupisa kwemhepo 79kW/m2.
- Flame fomu yeLTOF yakaderera-tembiricha yakachena okisijeni inopisa mukatiindasitiri choto, kupisa kwemoto kusina moto ndiko kunonyanya kushanda
(1) inogona kuderedza NOx emission ne90%;
(2) kana ichienzaniswa neyakagadziridzwa kana yakajairwa yakachena kupisa okisijeni, kupisa kusina murazvo ndiko kusinganzwisisike pakubuda kwemhepo, uye hapana shanduko yakakosha mukugadzirwa kweNOx.Avhareji mashandisirwo esimba uye chiyero chekupisa cheLTOF pure oxygen combustion tekinoroji mu28t aluminium alloy melting reflector.
