Innovation ya teknoloji yoyaka moto ya mafakitale

Pepalali likubweretsa ukadaulo watsopano woyaka ng'anjo ya mafakitale, ndipo ukadaulo umabweretsa kusintha kwakukulu pakusunga mphamvu ndi kuchepetsa utsi.

ng'anjo Industrial makamaka ogaŵikana smelting kuponyera ndi kutentha mankhwala ng'anjo mitundu iwiri.Zakale zimagwiritsidwa ntchito poyenga ndi kusungunula, pamene zotsirizirazi zimagwiritsidwa ntchito kutentha ndi kutentha kwa billets musanayambe kukonza.Mafuta ambiri omwe amagwiritsidwa ntchito potenthetsera zitsulo ndi gasi wachilengedwe kapena gasi wamumzinda, womwe umayenera kuperekedwa mumlengalenga ndi chowuzira mpweya kuti uyake.Monga tonse tikudziwira, mpweya umapangidwa ndi nayitrogeni, yomwe imapanga 78%, ndi mpweya, womwe umakhala 21% (ndi pafupifupi 1% ya mpweya wabwino).Nayitrogeni, yomwe ilibe mphamvu yoyaka, imakhala yokoka, yomwe simangochedwetsa liwiro la kutentha, komanso imachotsa kutentha kwa mpweya wa flue, ndikuwonjezera mavuto a chilengedwe.Pambuyo pazakafukufuku ndi chitukuko, Gulu la Linde la ku Germany linatulukira teknoloji yotchedwa low-temperature pure oxygen combustion technology (LTOF), yomwe ndi yoyenera kusungunula, kusungunula komanso kutentha kwazitsulo zopanda chitsulo monga chitsulo, mkuwa ndi aluminiyamu.

1. Kuyambitsa ukadaulo wocheperako kutentha kwa oxygen (LTOF) mu ng'anjo ya mafakitale

Zotsatira zazikulu zaukadaulo wowotcha mpweya wabwino ndi:

(1) palibe nayitrogeni amene amalowa m’ng’anjo;

(2) palibe nayitrogeni amene amachotsa kutentha mu mpweya wa flue;

(3) kuonjezera mphamvu ya ma radiation kutentha kutengerapo;

(4) mpweya wa chitoliro amakhala nthawi yaitali mu ng'anjo, kuti kusintha kutentha kutengerapo kwenikweni;

(5) popeza kulibe nayitrogeni pakuyaka kwa gasi wothandizira, imakhala ndi mphamvu zochepa pakuteteza chilengedwe ikatulutsidwa;

(6) kuyaka kothandizira kwa okosijeni koyera kumafika 77%, pomwe kutentha kwamlengalenga ndi 23% yokha.

2. Ubwino wa moto wochepa wamoto wa oxygen burner (LTOF) mu ng'anjo ya mafakitale

Cholinga cha chitukuko cha teknoloji ya low temperature pure oxygen combustion (LTOF) ndi kupititsa patsogolo mphamvu yosungunuka ndi mphamvu yowunikira.Chowotcha chapadera cha LTOF chimalola mpweya wotuluka mu ng'anjo kuti ulowe m'malo osakanikirana, ndikuchepetsa kuchuluka kwa okosijeni kutsogolo kwa chowotcha ndikuchepetsa kuchuluka kwa kuyaka, zomwe zimapangitsa kutentha kwa lawi lotsika lomwe lili pafupi ndi lawi lamoto. ya kuyaka kwa mpweya.Izi LTOF koyera mpweya kuyaka malawi makhalidwe amapangitsa kutentha mu ng'anjo yunifolomu, kuthetsa malo otentha m'deralo, kuchepetsa mafuta, kuchepetsa mpweya wotuluka ndi kuwongolera zitsulo kuchira.Kuyerekeza pakati pa kuyaka kwa mpweya ndi kutentha kochepa koyera kwa okosijeni, pakati pawo, kuyaka kwa mpweya, mphamvu yoyaka moto ndi 311kW, kuzirala kwa madzi ndi 231kW, pafupifupi nthawi zonse kuyeza mu aluminiyamu yosungunuka ndi 1131 ℃, ndi kutentha kwa kutentha ndi 79kW / m2.Low-kutentha koyera mpweya kuyaka, burner mphamvu 257kW, madzi kuzirala 66kW, mosalekeza muyeso wa zotayidwa mu mtengo pafupifupi 1152 ℃, kutentha flux 79kW/m2.

3. Flame mawonekedwe a LTOF otsika kutentha koyera mpweya woyaka mkating'anjo ya mafakitale, kuyaka kopanda moto ndikothandiza kwambiri

(1) ikhoza kuchepetsa kutulutsa kwa NOx ndi 90%;

(2) poyerekeza ndi kuyaka kwa okosijeni wamba kapena wamba, kuyaka kopanda lawi ndikosavuta kwambiri pakutha kwa mpweya, ndipo palibe kusintha kwakukulu pakupanga NOx.Avereji yogwiritsa ntchito mphamvu komanso kutentha kwa LTOF kopanda mpweya wabwino mu 28t aluminium alloy melting reflector.
