Steel siamchhuah hi "temperature" dik taka chhut a ni. 950℃charged billet atanga 1180℃discharge leh furnace-a extreme limit 1300℃thlengin, heat℃tin hian fuel cost sang tak a keng tel a ni. Mahse, bawlhhlawh lumna tam tak chu workshop chhungah direct-in a paih chhuak fo thin – hei hi professional bawlhhlawh lumna recovery heat exchanger a awm loh thu chiang tak a ni. Hei hian hnathawhna boruak a tichhe mai bakah hlawkna a tichhe zel bawk.
Tun hnaiah Vietnamese steel company lian tak QSP hot rolling line atanga internal report chuan retrofit plan hmantlak, quantifiable, leh return-clear{0}}clear tak a tarlang a: steel tunnel furnace heat exchanger system awmsa chu tihchangtlun a, tuna recovery unit awm mek hmunah recovery unit dah belh a ni. He ruahmanna hian "zero-carbon" tih thupui a zawm lo va, direct-a teh theih fuel savings leh investment returns a ngaihtuah zawk a ni – Ukada heat exchanger siamna hian thiamna thuk tak a thlenna field a ni.
I. Natna hmun: Temperature Drop leh "Naked" Heat Discharge
He steel plant-a tunnel furnace hian a tir chuan heat exchanger (recuperator) set thum a nei a, Zone 7 hian combustion air preheating hna a thawk a ni. Operating data tak takah chuan Zone 7 steel tunnel furnace heat exchanger hnua combustion air temperature chu a vaiin 450–460℃chauh a ni a , hei hi design value 530℃aiin a hniam hle a ni Heat exchange efficiency hniam zawk avangin heat deficit phuhruk nan system hian LPG extra a dah belh a ngai ta a ni.
Chu aia pawi zawk chu Shuttle zone pahnih (Zone 6)-ah hian heat exchange hmanrua an nei lo tak zet a ni. 1000℃vel exhaust gas chu workshop chhungah direct-in a paih chhuak a, hei hian heat wave leh thawm nasa tak a siam a – kut khatah LPG man to tak tak lei a ni a, a kut lehlamah boruakah lumna a paih bawk. Hei hi a ni chiang hle a, high-performance waste heat recovery heat exchanger chu a pawimawh lo hle.
II. A chinfel dan tur: High Temperature Recuperator (HTR) + Modular Additions te a awm bawk
Zone 7 tan: Recuperator pangngai chu High Temperature Recuperator (HTR) ah upgrade tur a ni. Thiltih bikte chu:
Material upgrade: Carbon steel heat exchange tube (1.4512 / S275JHD) zawng zawng chu high-grade stainless steel hmangin thlak la, heat transfer efficiency tihchangtlun nan internal flow path cross-section chu redesign rawh. Ukada heat exchanger siamtu professional kan nih angin, sustained 620℃+ operation atan metallurgical robustness kan dah pawimawh ber a ni.
Auxiliary system tihchangtlunna: Carbon steel combustion air piping awmsa hian hun rei tak-hun rei tak chhung temperature sang 500–550℃aia sang a tuar thei lo va, chuvangin high{3}}temperature stainless steel piping hmanga thlak a ngai a associated valve, seal, sensor, pressure transmitter, etc. te chu 620℃aia sang emaw, a tlukpui emaw tuar thei grade-ah tihsan vek a ni.
Fan capacity check: Upgrade hnuah pawh combustion fan awmsa chuan system air volume a la tawk thei em tih finfiah la, system hnathawh tikhawtlai thei tur fan capacity tling lo chu pumpelh rawh.
Revamp a nih hnuah Zone 7-a combustion air temperature chu 450℃aṭangin target 620 degree-ah a zuang chho dawn a ni. He leap hian thermodynamic hlawkna bulpui ber a keng tel a – flame stability tha zawk, fuel consumption tlem zawk, leh furnace temperature distribution inang tlang zawk. Chutiang performance upgrade chu Ukada heat exchanger siamtute design leh supply premium steel tunnel furnace heat exchanger atanga i beisei ang chiah a ni.
Shuttle zone-te tan: Exhaust gas system awm tawha inzawmkhawm, compact modular waste heat recovery heat exchanger hman. Flue gas hi furnace chung lama damper awmsa atang hian lakchhuah a ni a, heat exchanger thar kaltlangin heat chu combustion air-ah a transfer a, chu chu piping hmangin burner-ah thawn a ni. He design hian Shuttle zone-a moving load characteristics – compact, vibration-resistant, leh enkawl awlsam tak chu a ngaihtuah kim vek a ni.
III. Hlawkna: LPG Savings 10% aia tam, Kum 2–3 chhung Payback
Project-in a beisei angin, siamṭhat a nih hnuah tunnel furnace system pumpui hian LPG fuel 10% aia tam a humhim thei a ni. LPG man sang leh a inthlak danglam zel avangin kum khata economic lama hlawkna a tam hle a, kum 2–3 chhungin investment zawng zawng chu a let leh theih beisei a ni. He payback rang tak hi Ukada heat exchanger siamtu rintlak tak atanga waste heat recovery heat exchanger engineered tha tak-a chhinchhiahna a ni.
Direct fuel cost savings bakah hian hlawkna thup tam tak a awm a:
Carbon deposit tihtlem: Combustion efficiency sang zawk hian carbon black siamchhuahna nasa takin a tihtlem a, chu chuan sensor leh observation windows chhiatna rate a tihhniam a, hmanrua dam chhung a ti rei hle.
Hnathawh boruak tha zawk: Shuttle zone-te hian high{0}}temperature flue gas chu workshop-ah direct-in an paih chhuak tawh lo a, hei hian summer workshop temperature leh air quality nasa takin a tisang a ni.
Carbon emission tlahniam: LPG 10% humhim tih awmzia chu CO2 emission percentage inang vek a tihtlem tihna a ni – khawvel pum huapa carbon constraint khauh zual zel hnuaiah "green competitiveness" hmuh theih a ni.
IV. A awmzia: Steel Energy Saving hian "Deep Waste Heat Recovery" Hun a rawn lut ta.
Vietnamese steel company atanga he technical document hian a takah chuan industry pumpui tan replicable model a pe a ni. Chu chuan main process tihdanglam emaw, siamthatna lian tham atana production tihtawp emaw loh chuan, steel tunnel furnace heat exchanger system tihchangtlun leh tihpun mai mai hmangin energy efficiency lama hmasawnna nasa tak a awm thei tih a tilang a ni.
Zone 7-a carbon steel aṭanga stainless steel tube-a upgrade emaw, Shuttle zone-a heat exchange module awm lo dah belh emaw pawh ni se, a bulpui ber chu logic inang a ni – exhaust gas stream aṭanga bawlhhlawh lumna man a, combustion system-a thawn kir leh a ni. He "on-site recovery, on-site reuse" model hi a direct zawk a, hlohna a nei tlem zawk a, long-distance district heating emaw waste heat power generation aiin return a rang zawk bawk.
Engvangin Nge Ukada Heat Exchanger Siamna hi kan thlan?
Suzhou Ukada Energy Saving Technology Co., Ltd. , hian Ukada heat exchanger siamna lama kum tam tak technical experience nei tawh, steel tunnel furnace leh high{2}}temperature industrial application dangte tan bawlhhlawh heat recovery heat exchanger solutions customized a pe a ni. Project tin investment return logic chu chiang zawk leh hmuh theih zawkin kan siam a – material thlan atanga lifetime cost analysis thlengin. I bawlhhlawh lumna chu hlawkna teh theihah chantir turin Ukada biak rawh.
