Daim ntawv no qhia txog lub tshuab hluav taws xob ua hluav taws xob tshiab, thiab cov thev naus laus zis coj kev txhim kho tseem ceeb rau kev txuag hluav taws xob thiab txo qis emission.
Kev lag luam furnaces feem ntau muab faib ua smelting casting thiab kho cua sov rauv ob hom.Lub qub yog siv rau refining thiab smelting casting, thaum lub tom kawg yog siv rau cua sov thiab cua sov kho ntawm billets ua ntej ua.Feem ntau ntawm cov roj uas siv rau cov cua sov hlau yog cov nkev lossis cov pa hauv nroog, uas yuav tsum tau muab tso rau hauv cov huab cua los ntawm cov cua tshuab cua los txhawb kev sib txuas.Raws li peb txhua tus paub, huab cua yog tsim los ntawm nitrogen, uas suav nrog 78%, thiab cov pa oxygen, uas suav nrog 21% (thiab li 1% ntawm noble gases).Nitrogen, uas tsis muaj combustion nyhuv, yuav luag, uas tsis tsuas yog ncua lub cua sov ceev, tab sis kuj yuav tshem tawm cov cua sov nyob rau hauv lub flue roj, ntxiv rau ib puag ncig teeb meem.Tom qab xyoo ntawm kev tshawb fawb thiab kev loj hlob, Linde Group ntawm lub teb chaws Yelemees tau tsim Lub tshuab hluav taws xob tsis tshua muaj hluav taws xob ntshiab oxygen combustion (LTOF), uas yog tsim rau smelting, melting casting thiab kev kho cua sov ntawm cov hlau tsis muaj hlau xws li hlau, tooj liab thiab txhuas.
- Taw qhia ntawm qhov kub tsis tshua muaj siab ntshiab oxygen combustion technology (LTOF) hauv kev lag luam rauv
Cov teebmeem tseem ceeb ntawm cov pa ntshiab oxygen combustion technology yog:
(1) tsis muaj nitrogen nkag rau hauv qhov cub;
(2) tsis muaj nitrogen tshem tawm cov cua sov hauv cov pa roj;
(3) nce kev ua haujlwm ntawm hluav taws xob hloov hluav taws xob;
(4) cov roj flue nyob twj ywm ntev dua nyob rau hauv lub cub tawg, thiaj li txhim kho cov cua sov hloov pauv;
(5) txij li thaum tsis muaj nitrogen hauv combustion txhawb nqa roj, nws muaj kev cuam tshuam me ntsis ntawm kev tiv thaiv ib puag ncig thaum tso tawm;
(6) combustion txhawb cov nyhuv ntawm cov pa ntshiab mus txog 77%, thaum lub atmospheric combustion txhawb tus nqi tsuas yog 23%.
- Qhov zoo ntawm qhov kub tsis tshua muaj siab ntshiab oxygen burner (LTOF) nplaim taws nyob rau hauv qhov cub muaj
Lub hom phiaj ntawm qhov kub tsis tshua muaj siab ntshiab oxygen combustion (LTOF) thev naus laus zis kev txhim kho yog txhawm rau txhim kho lub peev xwm melting thiab kev ua haujlwm ntawm cov reflector.Qhov tshwj xeeb LTOF burner tso cai rau cov roj flue los ntawm lub qhov cub nkag mus rau hauv qhov sib xyaw ntawm qhov sib xyaw ua ke, diluting oxygen concentration nyob rau pem hauv ntej ntawm lub qhov cub thiab ua kom qis qis ntawm cov tshuaj tiv thaiv combustion, ua rau cov nplaim hluav taws kub qis dua uas nyob ze ntawm cov nplaim taws. ntawm huab cua-roj combustion.Qhov no LTOF ntshiab pa combustion nplaim cov yam ntxwv ua rau qhov kub thiab txias nyob rau hauv lub cub tawg zoo ib yam, tshem tawm cov chaw kub hauv zos, txo cov roj noj, txo cov cua kub emissions thiab txhim kho hlau rov qab tus nqi.Kev sib piv ntawm huab cua combustion thiab low-temperature ntshiab oxygen combustion, cov uas, huab cua combustion, burner hwj chim yog 311kW, dej txias yog 231kW, qhov nruab nrab tas li ntsuas nyob rau hauv molten txhuas yog 1131 ℃, thiab kub flux yog 79kW / m2.Low-temperature ntshiab oxygen combustion, burner hwj chim 257kW, dej txias 66kW, nruam ntsuas ntawm txhuas nyob rau hauv tus nqi nruab nrab ntawm 1152 ℃, kub flux 79kW/m2.
- Nplaim daim ntawv ntawm LTOF low-temperature ntshiab oxygen burner nyob rau hauvindustrial cub, nplaim dawb combustion yog qhov zoo tshaj plaws
(1) tuaj yeem txo NOx emission los ntawm 90%;
(2) piv nrog cov pa hluav taws xob zoo tib yam los yog cov pa ntshiab ntshiab combustion, flameless combustion yog qhov tsawg rhiab heev rau huab cua to, thiab tsis muaj kev hloov pauv tseem ceeb hauv NOx ntau lawm.Qhov nruab nrab lub zog noj thiab thermal tshuav nyiaj li cas ntawm LTOF ntshiab oxygen combustion tshuab nyob rau hauv 28t aluminium alloy melting reflector.
