Manure is a rich organic waste which, apart from its traditional use as a fertilizer, could be used as a bioenergy feedstock. In this sense, its utilization as a sole fuel or its co-combustion together with coal would be a choice for the management of this sort of biowaste. However, little is known about the behavior of this biowaste when submitted to high-temperature energy-conversion processes. Thus, the separate combustion of swine manure and coal and their co-combustion (10% dried weight of manure) were studied by simultaneous TG/MS dynamic runs. TG-MS analysis was successfully used as an easy rapid tool to assess the combustion of manure, alone or together with coal. Furthermore, non-isothermal kinetic analysis showed that the Arrhenius activation energy corresponding to the combustion of the blend (125.8-138.9 kJ/mol) was only slightly higher than that of manure (106.4-114.4 kJ/mol) or coal (107.0-119.6 kJ/mol).
粪便作为一种富含有机物的废弃物，除了传统的肥料用途外，还可以用作生物能源的原料。从这个意义上说，将其作为单一燃料使用，或与煤混合燃烧，是处理这种生物废物的一种选择。然而，对于这种生物废物在高温能源转化过程中的行为，人们知之甚少。因此，通过同步 TG/MS 动态运行，分别研究了猪粪和煤的单独燃烧及其共燃烧（粪便干重的 10%）。TG-MS 分析成功地用作评估粪便单独或与煤共燃烧的简单快速工具。此外，非等温热动力学分析表明，混合物燃烧的阿累尼乌斯活化能（125.8-138.9 kJ/mol）仅略高于粪便（106.4-114.4 kJ/mol）或煤（107.0-119.6 kJ/mol）的燃烧活化能。
