紫曰燃气热风炉耐火材质高可光纤测温,径草踏还生,径草踏还生.由于燃气热风炉的耐高温性,安全性,高风性,燃气热风炉一度成为目前各大工厂电厂青睐红人.燃气热风炉厂家在之前的文章中已经分析了我国炼铁系统热风温度偏低的原因。并且本企业针对我国高热值燃料缺乏的现状,阐述了用低热值煤气获得高热风温度的途径。先容了国内外热风炉燃烧控制技术的研究进展与应用概述,分别讨论了传统控制、数学模型及人工智能等热风炉燃烧控制方式的原理、实际应用概述及各自的优缺点,提出了热风炉燃烧控制技术的发展方向。
The refractory material of Ziyue Gas Hot Blast Furnace is high, which can be measured by optical fiber. The hot blast temperature of our country's iron-making system is low. Because of its high temperature resistance, safety and high wind resistance, the gas hot blast stove once became the favorite hot man in the power plants at present. The gas hot blast furnace manufacturer has analyzed the low hot blast temperature of our country's iron-making system in the previous articles. Reasons. In view of the shortage of high calorific value fuel in our country, the way to obtain high hot air temperature by using low calorific value gas is expounded. The research progress and application of combustion control technology for hot blast stove 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 stove is put forward. 燃气热风炉厂家主要针对5 000m3级别大型高炉的高风温热风炉技术进行技术比较分析,选择5 000m3级别大型高炉的设计实例,在风温、风量、燃烧介质等热风炉设计参数相同的同口径条件下,对Didier外然式热风炉和顶燃式热风炉进行本体表面积和表面散热比较,同时通过数值模拟分析,比较这2种热风炉的高温烟气速度分布、高温烟气流场分布、格子砖顶面温度分布,为大型高炉热风炉形式的合理选择提供建设性建议。通过比较分析,顶燃式热风炉的本体结构技术、流场热传输技术较其他形式热风炉具有明显优点,顶燃式热风炉技术是目前高风温热风炉技术发展的趋势,对于大型高炉采用顶燃式热风炉技术可以取得可观经济效益。
Gas-fired hot blast stove manufacturer mainly compares and analyses the technology of high-temperature hot blast stove for 5 000 m3 grade large blast furnace, chooses the design example of 5 000 m3 grade large blast furnace, and carries out the design of 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 stove. The top-fired hot blast stove technology is the trend of development of high-temperature hot blast stove technology at present. It can obtain considerable economic benefits for large blast furnace to adopt top-fired hot blast stove technology.

近期燃气热风炉厂家分析了我国热风炉的现状,认为影响我国多数热风炉风温水平进一步提高的原因主要有两点:一是拱顶温度过低;二是热风管道系统的设计存在问题。为了进一步提高风温,应提高双预热的温度,在高温区采用硅砖,完善自控系统以及纠正热风管道系统设计存在的问题。通过对热风炉的结构型式、耐火材料材质、燃烧器、高风温技术等问题的探讨,先容了国外对这些问题的解决方案,并结合我国热风炉发展实际,对我国热风炉未来的发展方向和趋势做了一些设想.
Recent gas hot blast stove manufacturers have analyzed the current situation of hot blast stoves in China. They believe that there are two main reasons affecting the further improvement of the air temperature level of most hot blast stoves in China: one is the low vault temperature; the other is the problems in the design of hot blast 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 control 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.
