摘要
针对可燃混合气体自燃着火极限设定的问题,运用控制体模型构建了可燃混合气体在热环境中的自燃模型,求解出不同热环境条件下的可燃混合气体上下限质量分数,并通过标准试验方法验证。试验分析表明,构建的可燃混合气体着火极限模型较好地反映出在不同环境条件下的可燃气体着火极限,并可为相关领域提供基础依据和求解方法。
As for the problem of setting combustible gas mixture spontaneous ignition limit,using the control volume model,the spontaneous ignition model of combustible gas mixture in the thermal environment was constructed,and the upper and lower limits of combustible gas mixture mass fraction in the different thermal environment had been obtained.The result had been validated by standard experiment.Experimental analysis showed that the model can reflect the combustible gases ignition limit in the different environmental conditions,and the solution method can provide the basis for related areas.
