紫曰燃氣熱風爐耐火材質高可光纖測溫,徑草踏還生,徑草踏還生.由於燃氣熱風爐成都收賬耐高溫性,安全性,高風性,燃氣熱風爐一度成為目前各大工廠電廠青睞紅人.燃氣熱風爐廠傢在之前成都找人公司文章中已經分析瞭我國煉鐵系統熱風溫度偏低成都收賬原因。並且本公司針對我國高熱值燃料缺乏收賬現狀,闡述瞭用低熱值煤氣獲得高熱風溫度成都找人公司途徑。介紹瞭國內外熱風爐燃燒控制技術的研究進展與應用概況,分別討論瞭傳統控制、數學模型及人工智能等熱風爐燃燒控制方式的原理、實際應用概況及各自的優缺點,提出瞭熱風爐燃燒控制技術的發展方向。
Ziyue Gas Hot Blast Furnace has high refractory material, which can be measured by optical fibre. It has survived in the past. Because of its high temperature resistance, safety and high wind resistance, the gas hot blast stove has once become the favorite hot man in the power plants. The gas hot blast stove manufacturers have analyzed the low hot blast temperature in the iron-making system of our country in the previous articles. The reason. In view of the shortage of high calorific value fuel in our country, the way to obtain high hot air temperature with low calorific value gas is expounded. The research progress and application of combustion control technology for hot blast stoves at home and abroad are introduced. The principle, practical application and advantages and disadvantages of traditional control, mathematical model and artificial intelligence are discussed respectively. The development direction of combustion control technology for hot blast stoves is put forward. 燃氣熱風爐廠傢主要針對5 000m3級別大型高爐的高風溫熱風爐技術進行技術比較分析,選擇5 000m3級別大型高爐的設計實例,在風溫、風量、燃燒介質等熱風爐設計參數相同的同口徑條件下,對Didier外然式熱風爐和頂燃式成都找人公司進行本體表面積和表面散熱比較,同時通過數值模擬分析,比較這2種成都***的高溫煙氣速度分佈、高溫煙氣流場分佈、格子磚頂面溫度分佈,為大型高爐成都***形式的合理選擇提供建設性建議。通過比較分析,頂燃式熱風爐的本體結構技術、流場熱傳輸技術較其他形式熱風爐具有明顯優點,頂燃式熱風爐技術是目前高風溫熱風爐技術發展的趨勢,對於大型高爐采用頂燃式熱風爐技術可以取得可觀經濟效益。
Gas-fired hot blast stove manufacturer mainly compares and analyses the technology of high-temperature hot blast stove of 5,000 m3 grade large blast furnace, chooses the design example of 5,000 m3 grade large blast furnace, and carries out this research on Didier external hot blast stove and top-fired hot blast stove under the same caliber condition with the same design parameters of hot blast stove such as air temperature, air volume and combustion medium. Comparing body surface area and surface heat dissipation, and through numerical simulation analysis, comparing the high-temperature flue gas velocity distribution, high-temperature flue gas field distribution and lattice brick top temperature distribution of these two hot blast stoves, providing constructive suggestions for the reasonable selection of large blast furnace hot blast stoves. Through comparative analysis, the main structure technology and flow field heat transfer technology of top-fired hot blast stove have obvious advantages over other types of hot blast stoves. The top-fired hot blast stove technology is the trend of the development of high-temperature hot blast stove technology at present, and can achieve considerable economic benefits for large blast furnaces by adopting top-fired hot blast stove technology.
近期燃氣熱風爐廠傢分析瞭我國熱風爐的現狀,認為影響我國多數熱風爐風溫水平進一步提高的原因主要有兩點:一是拱頂溫度過低;二是熱風管道系統的設計存在問題。為瞭進一步提高風溫,應提高雙預熱的溫度,在高溫區采用矽磚,完善自控系統以及糾正熱風管道系統設計存在的問題。通過對熱風爐的結構型式、耐火材料材質、燃燒器、高風溫技術等問題的探討,介紹瞭國外對這些問題的解決方案,並結合我國熱風爐發展實際,對我國熱風爐未來的發展方向和趨勢做瞭一些設想.
In recent years, gas hot stove manufacturers have analyz彩色沥清地坪ed the current situation of hot stoves in China. They believe that there are two main reasons affecting the further improvement of the air temperature level of most hot stoves in China: one is the low vault temperature; the other is the problems in the design of hot air pipeline system. In order to further increase the air temperature, the double preheating temperature should be increased. Silicon brick should be used in high temperature area, the automatic con环氧地坪trol system should be improved and the problems in the design of hot air pipeline system should be corrected. By discussing the structure type, refractory material, burner and high blast temperature technology of hot blast stoves, this paper introduces the solutions to these problems abroad, and makes some assumptions about the future development direction and trend of hot blast stoves in China based on the actual development of hot blast stoves in China.
