More and more Chengdu billing industry now introduces gas hot stove equipment in large quantities, including iron and steel industry. Manufacturing industry uses gas hot stove with Chengdu company's unique advantages: convenient and efficient, high conversion rate, high intelligence, high safety and low consumption. Chengdu billing waste gas is absorbed and converted into heat energy in production process. Manufacturers collect bills for new research and development and production. In the process of using high temperature and high efficiency gas hot blast stove, we should pay attention to Chengdu Finding Company and the process of R&D and exploration and share with you one by one. 养殖专用锅炉厂家说新型顶燃气热风炉燃烧技术势需要有一定技巧的。在公司引进、消化俄罗斯卡卢金顶燃气热风炉技术基础上,分析其技术优点和存在的不足,自行设计热风炉炉型、燃烧器结构多种方案,采用仿真、试验等手段研究了煤气、空气旋角、位置和布置方式变化的基本规律,并优选了一种可行方案,厂家在高炉预热炉上进行应用试验。仿真和冷态试验结果表明,新开发的热风炉具有结构紧凑,工艺设计简单,炉顶、炉墙温度较低,燃烧完全等优点。厂家投产应用表明,该热风炉运行良好,风温达到预期目标,满足了高炉炼铁生产需要。
The manufacturer of special boilers for aquaculture said that the combustion technology potential of the new top gas hot blast stove needs certain skills. On the basis of introducing and digesting the technology of Kalu Golden Top Gas Hot Blast Furnace in Russia, the company analyzed its technical advantages and shortcomings, designed various schemes of hot blast furnace type and burner structure by itself, studied the basic law of the change of gas, air rotation angle, position and layout mode by means of simulation and experiment, and optimized a feasible scheme. The manufacturer responded on the preheating furnace of blast furnace. Use the experiment. The results of simulation and cold test show that the newly developed hot blast stove has the advantages of compact structure, simple process design, lower temperature of furnace top and wall and complete combustion. The application in production shows that the hot blast stove runs well, the air temperature reaches the expected target, and meets the needs of blast furnace ironmaking production.
燃气热风炉对宝钢高炉热风炉实际生产数据进行了测试与收集,在此基础上进行了热平衡计算,并对计算结果进行了对比分析。结果表明:四高炉热风炉热效率较高,处于国内先进水平,但一高炉热风炉热效率较低。主要原因是一高炉热风炉燃烧不充分,散热损失大,烟气余热回收装置利用水平较低。可采用合理的空气过剩系数或富氧燃烧方式,增强保温措施,改造或更换烟气余热回收装置,提高一高炉热风炉热效率。

The actual production data of Baosteel BF hot blast stove were tested and collected by gas hot blast stove. On this basis, the heat balance calculation was carried out, and the calculation results were compared and analyzed. The results show that the thermal efficiency of the hot blast stove of No. 4 BF is higher than that of the domestic advanced level, but the thermal efficiency of the hot blast stove of No. 4 BF is lower. The main reason is that the hot blast stove of a blast furnace has insufficient combustion, large heat loss, and low utilization level of waste heat recovery device of flue gas. Reasonable excess air coefficient or oxygen-enriched combustion mode can be adopted to enhance thermal insulation measures, and the flue gas waste heat recovery device can be reformed or replaced to improve the thermal efficiency of a blast furnace hot blast stove.
