More and more industrial industries are now introducing gas-fired hot-blast stoves in large quantities, including iron and steel industries. Manufacturing industries use the unique advantages of gas-fired hot-blast stoves: convenient and efficient, high conversion rate, high intelligence, high safety and low consumption. The exhaust gas generated in the production process can be absorbed through and converted into heat energy. Research and development of high temperature and high efficiency gas hot blast stove, in the use of the process should pay attention to and research and development process and share with you one by one. 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 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 Stove in Russia, the company analyzed its technical advantages and shortcomings, designed various schemes of hot stove 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 one. Feasible plan, the manufacturer carries on the application test in the blast furnace preheating furnace. 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.
In view of the problem of using single blast furnace gas to realize the air temperature above 1250 C in hot blast stove, the manufacturer compares and analyses various domestic air gas preheating technologies, and considers that the combination of high temperature preheating furnace and separate heat pipe heat exchanger technology is a better scheme to achieve high air temperature. For this reason, by means of simulation and experiment, the uniformity of distribution of flow field and temperature field in preheated hot blast stove, gas hot blast stove and mixed blast stove is systematically studied.
According to the characteristics of hot blast stove combustion control, the manufacturer combines the fuzzy control technology with the neural network technology, and puts forward a kind of hot blast stove combustion control method based on the fuzzy neural network. This method takes full account of the characteristics of non-linearity, difficulty in modeling and strong coupling of the system. Fuzzy neural network is used to extract the fuzzy rules quickly. Through fuzzy learning, the problem that the rules are difficult to obtain in the application of fuzzy control is solved.
The manufacturer said that the combustion chamber of the new biomass briquette hot blast stove was mainly designed to adapt to the combustion of bulk and rod briquette fuels. It can also be used for the combustion of partially Granular Briquette fuels. It mainly consists of feeding mechanism, combustor part and ash removal mechanism. It realizes the automatic feeding of bulk and rod briquette fuels and also can be used for the combustion of partially Granular Briquette fuels. Automatic removal of ash. The combustion chamber of the biomass briquette fuel hot blast stove can effectively reduce the insufficient combustion of solid fuel and volatile gas, control the temperature of the furnace within a certain range, reduce the generation of ash and slag, and effectively remove ash and slag.
