Lub Siab-Velocity Burner (feem ntau hu ua siab- nrawm nozzle) yog cov khoom siv hluav taws xob tshwj xeeb uas tsim los tsis yog rau kev siv roj combustion nkaus xwb tab sis, qhov tseem ceeb tshaj, tsim kom muaj qhov siab - kub, siab - dav hlau ceev kwj (feem ntau ncav cuag speeds ntawm 100-300 m). Lub dav hlau muaj zog no tau siv dav los txhim kho cov cua sov hloov pauv, ua rau lub tshuab cua sov cua sov, thiab tsim cov dej ntws tshwj xeeb, ua rau nws yog ib qho tseem ceeb rau kev txhim kho cov khoom siv niaj hnub no.
I. Txoj Cai Ua Haujlwm Tseem Ceeb & Kev Tsim Kho Tshiab
Tsis zoo li cov tsoos burners uas tsom ntsoov rau cov nplaim taws ruaj khov, siab - cov hluav taws kub ceev siv lub tswv yim tsim tshwj xeeb raws li "kev sib cais ntawm combustion thiab kinetic zog hloov."
1. Theem 1: Siab -Efficiency combustion Zone
Roj thiab huab cua ua tiav sai, sib tov sib xyaw thiab khaus combustion nyob rau hauv lub compact chamber ntawm muaj zog swirl los yog premixing technology. Lub combustion chamber no muaj qhov tso tawm cov cua kub siab heev thiab yog tsim los ntawm siab - cov ntaub ntawv kub zoo li ceramics lossis cov alloys tshwj xeeb.
2. Theem 2: Kinetic Energy Transfer Zone (Mixing/Expansion Chamber)
Qhov tshwm sim kub combustion gases nkag mus rau hauv ib lub raj sib tov los yog expansion chamber. Ntawm no, "tempering cua" tuaj yeem qhia tau meej meej tswj qhov kawg qhov hluav taws xob qhov hluav taws xob kub thiab ntws tus nqi. Lub geometry ntawm cheeb tsam no (piv txwv li, Laval nozzle qauv los yog cov yeeb nkab ncaj) ua tau zoo hloov lub thermal thiab siab zog ntawm cov roj rau hauv lub zog kinetic.
3. Qhov hluav taws xob: Siab -Speed Jet
Thaum kawg, cov kwj ntawm cov khoom sib xws - kub, siab heev - cov pa tawm nrawm tau tawm ntawm lub nozzle, ua rau lub siab - nplaim taws ceev (siab- dav hlau kub). Ntau qhov kev tsim qauv siv lub dav hlau qhov kev nkag mus rau hauv lub qhov cub kom rov ua kom cov pa taws ua pa, ua kom cov nplaim taws kub hnyiab tau zoo.
II. Cov yam ntxwv tseem ceeb & Cov txiaj ntsig zoo
- Exceptionally High Heat Transfer Efficiency:Lub siab - cov pa roj nrawm ncaj qha cuam tshuam rau cov khoom ua haujlwm, cuam tshuam rau txheej txheej ciam teb. Qhov no ua rau lub convective tshav kub hloov coefficient ob peb zaug rau qhov kev txiav txim ntawm qhov loj dua li cov tsoos radiant tshav kub hloov, txo cov sij hawm cua sov.
- Superior Furnace Temperature Uniformity: Lub dav hlau siab - nrawm nrawm nrawm nrawm rau qhov cua sov cua, kom ntseeg tau tias muaj qhov sib txawv ntawm qhov kub thiab txias ntawm huab cua, tshem tawm cov chaw kub lossis txias hauv zos.
- Compact Structure: Lub siab combustion siv tau tso cai rau lub cev me me piv rau cov tsoos burners ntawm lub zog sib npaug.
- Flexible Control: Qhov kub thiab qhov nrawm ntawm qhov hluav taws xob qhov hluav taws xob tuaj yeem hloov kho tau yooj yim los ntawm kev hloov pauv roj, thawj huab cua, thiab theem nrab (tempering) cua ntws.
- Tsawg Nitrogen Oxide (NOx) Emissions:Flue gas recirculation thiab tsim ib qho chaw ntsuas kub zoo tiv thaiv kev tsim ntawm thermal NOx, muab kev ua haujlwm zoo ib puag ncig.
III. Thawj daim ntawv thov teb
Tus nqi tseem ceeb ntawm siab - cov hluav taws kub ceev yog nyob rau hauv "siv roj ntws hloov cov nplaim taws zoo li qub" kom ua tau zoo cua sov thiab kev kub ntxhov. Lawv yog dav siv nyob rau hauv:
- Thaum tshav kub kub kho Industrial Furnaces: Cov ntawv thov kom muaj cua sov sai, xws li hlau strip annealing kab, aluminium aging furnaces, thiab steel quenching / tempering furnaces.
- Chemical & Materials Processing:Cov tshuaj tsuag kom qhuav, cov txaj fluidized, rotary kilns, thiab cua riam hauv cov hlau galvanizing / aluminizing kab.
- Khoom noj khoom haus & Textile Industries: Loj- nplai cov kab ziab zaub mov thiab tsis yog- ntaub npuag kub- cov kab ntau lawm kab.
- Khib nyiab Gas & Liquid Incineration: Cov xwm txheej yuav tsum muaj kev sib xyaw ua ke kom muaj kev puas tsuaj tag nrho.
- Kev Tshawb Fawb & Kev Ntsuas:Cov khoom siv uas yuav tsum tau muaj siab -enthalpy, siab - cov pa roj nrawm, xws li cua qhov cua sov.
Cov ntsiab lus
Los ntawm nws cov qauv tsim tshwj xeeb, lub siab -v taws kub burner zoo kawg nkaus integrates efficiency combustion nrog kinetic zog tso zis, daws qhov mob cov ntsiab lus ntawm low heat transfer efficiency thiab tsis zoo kub uniformity pom nyob rau hauv ib txwm cua sov txoj kev. Nws ua ke cov txiaj ntsig zoo hauv kev txhim kho cov khoom lag luam zoo, txuag hluav taws xob, thiab txo qis emissions ua rau nws yog ib qho tseem ceeb ntawm kev siv tshuab rau kev tsim kho tshiab thoob plaws ntau qhov chaw ua cua sov.
