宝钢一号高炉热风炉数学模型分燃烧管理和设备管理两部份,由煤气流量计算、拱顶温度控制、废气温度控制三个子模型构成。在高炉投产前后,经模拟试运转和在线调试,实现了热风炉燃烧的计算机闭环控制。一年来生产实践表明,此模型可靠性好,操作简便,有利于提高热效率,经济效益明显。同时指出,当燃烧和送风工艺改变时,如对燃烧气体进行预热、应用转炉煤气作为燃料和并联送风时完全不混入冷风等技术采用的情况下,需将数学模型作相应的修改和进一步的开发。
Baosteel Blast furnace mathematical models of combustion stoves and equipment management two parts, from the gas flow calculation, vault temperature control, exhaust gas temperature control of three sub-models. Before and after the blast furnace put into operation, the computer closed-loop control of the combustion of the hot blast stove has been realized through the simulation test operation and on-line debugging. A year of production practice shows that the reliability of this model, easy to operate, is conducive to improving thermal efficiency, economic benefits. Also pointed out that when the combustion and blowing process changes, such as the preheating of combustion gases, the use of converter gas as a fuel and parallel air supply is not mixed with cold air and other technology used in the case, the mathematical model to be modified accordingly and Further development.
