摘要： 对详细化学反应机理的简化是高炉煤气燃烧模拟的一个重要步骤.使用CHEMKIN软件,针对一维稳态层流预混燃烧模型,通过分析高炉煤气内主要组分在各个基元反应中对燃烧速率的影响,将详细化学反应机理简化为高炉煤气燃烧的基干机理.将化学反应简化机理与详细机理的计算结果进行对比验证,用详细反应机理计算高炉煤气燃烧反应的时间为18s,而使用简化反应机理的计算时间则不到1s.组分摩尔分数差值不超过0.4%,验证了简化机理的可靠性.

Abstract: Simplifying of the complex reaction mechanism is of importance to the numerical simulation of the combustion of BFG (blast furnace gas). The software CHEMKIN was used to solve a one-dimensional mathematical model of steady-state pre-mixing laminar combustion. By analyzing the effects of basic components of BFG on the combustion rate in all elementary reactions, the simplified reaction mechanism was obtained and becomes the basic mechanism of BFG combustion. Compared the computed result by the simplified mechanism with that by complex mechanism, the time required for the former was less than 1 s but that for the latter was about 18 s. The differences between molar fractions of the BFG components computed by the two mechanisms were less than 0.4%. The reliability of the simplified reaction mechanism is therefore verified.
