简介：exergy分析就在葡萄牙(修剪的森林残余和藤)生产的甲烷和agro工业的残余的燃烧而言被执行。关于一个热力学的过程的不能反逆的性能是路径依赖者，燃烧过程作为各源于不同假想路径正在认为一个人由四主要子进程描绘了：混合的反应物，燃料氧化，内部热精力交换(热转移)，并且产品混合。exergetic效率用使用可视化Basic家代码开发的零个维的模型被计算。exergy损失主要由于内部热精力交换子进程，这被结束。当没有以前的燃料氧化，反应物被预热直到点火温度时，从这子进程的exergy损失更高。在另一方面，全球exergy破坏能是在氧化剂溪流上增加压力，反应物温度和氧内容的minored。这方法论允许有更大的exergy损失的现象和进程的鉴定，这些损失为什么并且怎么发生的理解有联系到对关键的每个系统的参数的exergy变化作为一种竞争技术从生物资源产品实现syngas燃烧。

简介：点火的分叉分析和催化燃烧在的扑灭一突然微隧道被执行，laminar模型作为流动模型合并了。横向的Thiele模量和滞留时间的平方被用作分叉参数。点火和扑灭行为上的不同参数的影响被调查。所有这些参数在点火和扑灭的分叉行为上有大效果在，这被显示出突然微隧道。燃烧的分叉行为上的流动模型的效果也被分析。结果证明与扁平的速度侧面模型比较，为laminar模型的案例，点火的温度和燃烧的扑灭更高，不稳定的多重答案区域更大。
