Recently, the oxidati長東on furnace, the core equipment of ca老費rbon fiber production請在 line with independent intellec明綠tual property rights ind短多ependently developed 從雨and manufactured by JGST, ha區飛s been installed 笑匠and commissione朋理d in Hyosung (HYOSUNG ADVANCED MAT對為ERIALS) factory in J姐請eonju, South Kor少土ea. The acceptance was successfully co姐器mpleted, and the two家笑 key technical ind會路icators of the o自匠xidation furnace, the uniformity of w坐得ind speed and the uni煙員formity of temp謝弟erature, reached th讀也e international advan年樂ced level. This cross-border cooper請懂ation is the seco是農nd cooperation between the t司外wo parties since the first oxid體好ation furnace cooperation in 2船拿019. It is anothe筆器r major milestone in the history of i刀多n the history of JGST eq報那uipment manufacturing, 作小and the national brand in國分 the field of carbon f暗線iber equipment shines again on術玩 the international stage.
As one of the seven major corporations見相 in South Korea, Hyosun火可g Group started to independen東書tly develop carbon fibers問什 in the early 200低化0s. In 2011, Hyosung co亮還operated with research ins朋市titutes such as Korea Carbon Fusio樹文n Technology Insti林年tute in Jeonju, North Je她慢olla to develop樂西 TANSOME carbon fiber for制關 the first time in Korea. So far理業, Hyosung has put into operation t身舊hree high-performance carbon fiber prod藍唱uction lines at間吃 its plant in Jeonju, North J匠姐eolla Province. The products are mai刀放nly T700/T800 grade car要數bon fibers. As an oxidation furnace su新一pplier, JGST is ve習輛ry honored to participate in the co森件nstruction of the 件對second and third carbon fiber producti開爸on lines.
Based on the solid foundation la章紅id by the previous cooperation and和他 the stable and ef地美ficient operation of the oxidation靜地 furnace, Hyosung r火人ecently confirmed道器 the order for the oxidation furn商做ace required for the fourth pr厭雜oduction line to JG校聽ST. According to public reports, the 坐又new line will be put into oper中匠ation in April 2023.下海 The expansion is aimed at mee事老ting the growing demand for st照文orage of eco-friendly vehicle 請錯fuels such as hydrogen and natural gas物北, especially the revitalization o冷唱f the hydrogen energy econo弟來my is expected to drive the de章錯mand for pressure vessels for s可媽toring gases, w物低hile the application of c行空arbon fiber pressure城能 vessels mainly for hydrogen fu內慢el vehicles, hydrogen refueling stat影數ions and hydrogen transportation.爸很
As the core equipme問兵nt in the carbon fiber厭請 production line, 用訊the oxidation fu科要rnace plays a pivotal role in the e兵和ntire production可兒 and product quality. Th笑問e oxidation furnace de話跳livered by Jinggong Technol在友ogy this time and the oxi見還dation furnace for th店在e next 4th line are呢時 different from the current m湖雜ainstream electric heating外這 type oxidation furnace in雪睡 China. For the first t放明ime, a natural gas heater is used 高木as the heat source of the o生服xidation furnace. The RHT 東路Indirect Air Heater features an分站 industry leading burn喝朋er, combustion chamber an歌海d exhaust duct i金南nto a self-contained uni內到t for easy installation and optim船村um performance. At 店媽the same time, the RHT indirect air hea新文ter is also a fully integrated科低 system, including: h關那eat exchanger, combus化看tion chamber, burner, combustion fa但答n, gas valve gr醫美oup and combustion control sys制身tem. The heater body is made 我學of superalloy. 熱說Its basic working principle is國票: according to the set temperature of通愛 the oxidation 話開furnace and the actual temperature 花議of the furnace body, to adjus厭子t the opening of the 服城natural gas inlet valve, so as to ad麗理just the consumption of natural gas, an河服d to adjust the heat out了房put of the heater. 森吃After the natural冷小 gas is combusted in the com金作bustion chamber,山錢 the high-temperature gas prod分小uced will exchange hea笑熱t energy with the proces志得s air through the heat e司拍xchanger composed of厭動 tube bundles, and finally be dis開資charged from the waste outlet. 男會The combustion cham讀她ber and the heat exchanger are l很一ocated in the circulating air duct of 子明the oxidation f相如urnace. The air in the furn我國ace continuously flows t會媽hrough the surface of th爸媽e combustion chamber and the heat exch風月anger to absorb the heat en懂錢ergy generated by the h服子eater to heat the air in the furnace. T人但he circulating air duct where the拍不 heater is located has undergone accu老年rate calculation and 能子professional CFD simulat視友ion to obtain th湖大e optimized air d少窗uct structure, which can ma文拿ke the circulating舞志 air evenly distribu鄉低ted on the surface of the combus離現tion chamber and the heat e資哥xchanger, and ensure that t工高he combustion chamber and the heat能又 exchanger can be友門 evenly distributed. It avoi林拍ds local high temperature caused by uns頻一table airflow, which leads t為熱o damage to the c木煙ombustion chamber and hea離鄉t exchanger. At the same time, it has家上 the lowest process air press理道ure drop and reduces system losses.但水
l RHT indirect air heaters also have the用跳 following features:
l Isolation of combustion exhaust gas fro就機m process air
l Furnace over temperature pr些說otection
l Process air volume detec雨小tion
l Thermal expansion free floa媽劇ting design
l Thermal efficiency 60-75%
l Low process air pressure dr外有op

In addition, the combusti可動on system can have the f裡坐ollowing safety functions u風技nder the premise of satisf和美ying the application:
Gas high pressure友大 protection, gas low pressure 視村protection, dou你了ble-valve internal leakage detection媽工, automatic purging, fu討用rnace over-temperature pr劇間otection, combustion-長路supporting air detection又靜, circulating air 著畫detection, self-ch說報ecking UV flame detector, 農的dual-fire detection automati少雪c flame detection, 如站etc.
At present, under the natio店都nal general policy of energy cons算快ervation and emissio畫如n reduction, it is imper知公ative to reduce the energy年店 consumption per unit of industri坐玩al added value. At this st體線age, the oxidation furnaces used in d要快omestic industrialization月刀 are basically mainly electric heat錯場ing. The installed p西藍ower of the oxidatio冷機n furnaces in most producti師水on lines has exceeded 50% of多做 the total power of the entire li船窗ne, which is a complete energy 報熱consumption. At the moment when 開煙the market is chasing high-efficiency 廠工and low-energy-consumption equipmen離花t, JGST started from討西 the oxidation furnace. After ne區哥arly 2 years of continuous雪房 testing and optimi我地zation, it has succ我舊essfully developed a natural gas-heate到年d oxidation furnace 信現and completed its industrial ap光友plication.
l Compared with the electric heating體外 type oxidation furnace, the natura請坐l gas heating type oxidation furnace ha土長s the following a動人dvantages:
l 1) Project invest那河ment
l Substantially reduce the input of high 這說and low allocation of public w森拿orks of the project
l Reduce equipment elect木匠rical control and cable investment
l 2) In terms of operating energy con的相sumption
l Taking a convent愛但ional 3-meter oxidation fu裡外rnace as an example, und場快er no-load 250°C, the temperature of 外她a single temperature拿房 zone is controlled for one ho內花ur. 19.6 cubic meters. A sin白劇gle carbon fiber 畫科production line is generally configur林醫ed with 8-12 temperature zones, and t姐他he production line runs f唱煙or more than 7,玩快200 hours per year, and the知吧 reduction in operati喝玩ng costs within a year will be c藍上onsiderable.
Apparently, under the a東暗ctual full load condi很問tion, the operat動熱ing costs of electric heating and natu鐵聽ral gas heating will be adju子業sted accordingly according討體 to different raw wires, pr睡要ocess temperatures,物現 electricity pric請很es and natural gas pr舞市ices in different region用西s, and the cost reducti現外on advantage of natural gas will also 身冷be reduced or enlar大她ged accordingly. But the advan說司tages are always the拿兵re, especially in 跳筆areas where industrial el友照ectricity is expensive.
In recent years, c開工arbon fiber, as an 她妹indispensable strategic new materi可著al for our country's eco信這nomic development an風電d national defense construct村花ion, is in strong deman去都d in the fields of wind power錯刀 generation, pressure vessels, aerosp窗光ace, sports and le唱商isure, photovoltaic carbon and carbon p做雪roducts, as well as ever increasing d雜近emand for projects鄉土 under construction and announ議機ced to be built in China. Mo購一st industries, fro外訊m the large expansion還著 of production capacity to the b工靜alance of supply and demand, 媽化have experienced the baptism of prod土什uct quality and cost. In the futur就件e, among hundreds of companies,輛信 the main competition of carbon fiber司紅 will also be produc上畫t quality and cost. We ha機跳ve reason to belie紙業ve that the application of natural河姐 gas heating type oxidation fu得笑rnace will become more 體下and more popular.
