Ni gute ingano y'uduce twa coke mbisi bigira ingaruka ku buryo urwego rw'ibikoresho rushobora kwinjira neza no ku buryo calcination iba imwe mu itanura rizunguruka?

Ingaruka z'ingano y'ibice by'umusemburo bya coke ku buryo ibintu bisohoka mu buryo butangaje ndetse n'uburyo calcination ingana mu itanura rizunguruka zishobora gusesengurwa binyuze mu isano iri hagati y'ibipimo by'ingano y'ibice n'ibipimo by'imikorere nk'ibi bikurikira:

I. Ingaruka z'ingano y'uduce duto ku buryo urwego rw'ibikoresho rugumaho

Ingano y'uduce duto (Agaciro ka PDI)

• Ibisobanuro: Igipimo cy'ingano y'uduce duto dukwirakwira (PDI = D90/D10, aho D90 ari ingano y'agace gashyirwamo uduce duto aho 90% by'uduce dunyura, naho D10 ikaba ingano y'agace gashyirwamo uduce duto 10%.
• Ishusho y'ingaruka:
  Agaciro gato ka PDI (kerekana ingano y’uduce duto) gatuma urwego rw’ibikoresho rugira porosity nyinshi, aho igipimo cy’impinduka (agaciro ka K) kiyongeraho hafi 15% kugeza 20%.
• Amakuru y'igerageza:
  Iyo PDI igabanutse kuva kuri 2.0 kugera kuri 1.3, igabanuka ry'umuvuduko mu itanura rigabanukaho 22%, kandi igipimo cy'umuvuduko wa gazi kiyongeraho 18%, bigaragaza ko hari iterambere rikomeye mu bijyanye no kwinjira mu kirere.
• Uburyo:
  Ingano y'uduce duto igabanya imiterere y'uduce duto twuzuza icyuho kiri hagati y'uduce duto, birinda ingaruka z'"uduce duto" bityo bigagabanya ubudahangarwa bw'umwuka.

Ibice Bito by'Uduce (<0.5 mm)

• Ingano y'ingenzi:
  Iyo igipimo cy'uduce duto kirenze 10%, ubushobozi bwo kwinjira mu kirere burushaho kugabanuka cyane.
• Isano y'ingano:
  Kuri buri kwiyongera kwa 5% by'uduce duto, kugabanuka k'umuvuduko mu itanura kwiyongeraho hafi 30%, kandi umuvuduko w'umwuka ugabanukaho 25%.
• Inyigo y'Urubanza:
  Mu itanura rya peteroli rikoresha calcium ya coke, iyo ingano y’utunyangingo tw’amavuta yiyongereye kuva kuri 8% kugeza kuri 15%, igitutu kibi ku mutwe w’itanura kizamuka kuva kuri -200 Pa kugeza kuri -350 Pa, bigasaba kongera imbaraga z’umufana utera ingufu kugira ngo akomeze gukora, bigatuma ingufu zikoreshwa ziyongeraho 12%.

Ingano mpuzandengo y'uduce duto (D50)

• Ingano nziza:
  Uburyo bwiza bwo kwinjira buboneka iyo D50 iri hagati ya mm 8 na 15.
• Ingaruka zo kuyobya:
  Iyo D50 iri munsi ya mm 5, ubwiyongere bw'urwego rw'ibikoresho bugabanuka bukagera munsi ya 35%, kandi igipimo cy'ubwiyongere kigabanukaho 40%;
  Iyo D50 irenze mm 20, nubwo imyenge iba myinshi, agace k'aho utwo duce duhurira kagabanuka, bigabanya ubushobozi bwo kohereza ubushyuhe ho 15% kandi bikagira ingaruka ku buryo butaziguye ku buryo bwo gukaraba.

II. Ingaruka z'ingano y'uduce duto ku buryo bumwe bwo gukaranga

Ihindagurika ry'Ubushyuhe (σT)

• Ibisobanuro:
  Ikimenyetso cy'imibare kigaragaza ubwiyongere bw'ubushyuhe bw'umurambararo mu itanura, hamwe na σT ntoya igaragaza calcination imwe.
• Ingaruka z'ingano y'uduce duto:
  Iyo ingano y'uduce duto ingana (PDI < 1.5), σT ishobora kugenzurwa muri ± 15℃;
  Iyo ingano y'uduce tudahuje (PDI > 2.5), σT irakura ikagera kuri ± 40℃, bigatuma ishyuha cyane cyangwa igatwika buhoro buhoro.
• Inyigo y'Urubanza:
  Mu itanura rizunguruka rya aluminium carbone, binyuze mu kunoza ingano y'uduce kugira ngo tugabanye PDI kuva kuri 2.8 kugeza kuri 1.4, ihindagurika ry'ibipimo by'ihindagurika mu bicuruzwa rigabanuka kuva kuri 0.8% kugeza kuri 0.3%, bikongera cyane ubwiza bwa calcination.

Umuvuduko w'Iterambere ry'Inzira yo Guhangana (Vr)

• Ibisobanuro:
  Umuvuduko wo kwihuta kw'uburyo bwo gukora calcination mu gice cy'ibikoresho, bigaragaza imikorere myiza ya calcination.
• Isano n'ingano y'uduce:
  Kuri buri kwiyongera kwa 10% mu gipimo cy'uduce duto (<3 mm), Vr yiyongeraho hafi 25%, ariko ishobora gutera ingaruka zihuse cyane no gushyuha cyane mu gace runaka;
  Kuri buri kwiyongera kwa 10% mu gipimo cy'uduce duto (> mm 20), Vr igabanukaho 15% bitewe no kwiyongera k'ubushyuhe.
• Aho kuringaniza:
  Iyo ingano y'uduce dukwirakwira mu buryo bubiri (urugero, uruvange rwa mm 3-8 na mm 15-20), Vr ishobora kuguma mu rugero rwiza (0.5-1.0 mm/min) mu gihe igenzura ko ibintu byose bingana.

Igipimo cy'ibizamini by'ibicuruzwa (Q)

• Isano y'ingano:
  Kuri buri ngano y’ibice 0.5 byiyongereyeho ubunini bw’ibice (ni ukuvuga kugabanuka kw’agaciro ka PDI), igipimo cy’ubuziranenge bw’ibicuruzwa cyiyongeraho hafi 8%;
  Ku igabanuka rya 5% ry'ibice bito by'udukoko, igipimo cy'imyanda iterwa no gutwika cyangwa gutwika cyane kigabanukaho 12%.
• Amakuru y'inganda:
  Mu itanura rizunguruka rya titanium dioxide, binyuze mu kugenzura ingano y'uduce twa coke y'ibikoresho fatizo (D50 = 12 mm, PDI = 1.6), ihindagurika ry'ubuziranenge bw'ibicuruzwa rigabanuka kuva kuri 1.2 kugeza kuri 0.5, kandi igipimo cy'ibicuruzwa byo mu rwego rwa mbere kiriyongera kuva kuri 75% kugeza kuri 92%.

III. Inama zuzuye zo kunoza imikorere

Intego zo kugenzura ingano y'uduce duto:

• D50: mm 8-15 (ishobora guhindurwa hakurikijwe imiterere y'ibikoresho);
• PDI: <1.5;
• Ibipimo by'uduce duto (<0.5 mm): <8%.

Ingamba zo Kuvugurura Imikorere:

• Koresha inzira zo gusya no gusuzuma mu byiciro byinshi kugira ngo urebe ko ingano y'uduce twinshi ikwirakwira;
• Kora isuzuma mbere yo gukora (urugero, gukoresha briquet) ku duce duto kugira ngo ugabanye igihombo cyo mu kirere;
• Ongera ingano y'uduce duto ukurikije ubwoko bw'itanura (uburebure n'umurambararo, umuvuduko wo kuzenguruka), urugero, ukoresheje uduce duto nk'igice cy'ingenzi cy'amatanura maremare kandi wongereho uduce duto tw'amatanura magufi.

Gukurikirana no gutanga ibitekerezo:

• Shyiramo ibikoresho byo gusesengura ingano y'uduce kuri interineti kugira ngo bigenzure uko uduce tw'uduce twinjira mu itanura dukwirakwira mu buryo nyabwo;
• Huza hamwe n'uburyo bwo gushushanya ubushyuhe buri mu itanura (CFD) kugira ngo uhindure ingano y'uduce duto n'uburyo bwo gukaraba.
