Self-ignition of solid fuels storage is one of the main causes of human and economic losses. Additionally, each fire caused by this phenomenon emits an amount of toxic gases that contributes on the development of climate change. Nowadays, several methodologies are used in order to detect the self-ignition tendency of solid fuels, but they have as main disadvantages the amount of money and time that they require. The aim of this study is to propose a methodology of detection of incipient self-ignition of solid fuels through the measurement of gas emissions. This study compares existing methodologies to detect self-ignition tendency, such as TG, DSC or susceptibility, and to combustion related gas emission results. Different methods have been used to evaluate the results from the gas emission test, showing that interval and inflexion methods provide early detection of the self-heating process. With this methodology, it is possible to determine this process in advance with the equipment currently available in every industrial facility, reducing costs and improving efficiency.

固体燃料存储的自燃是造成人员和经济损失的主要原因之一。此外，由该现象引起的每场火灾都会散发出一定数量的有毒气体，这些气体有助于气候变化的发展。如今，使用了几种方法来检测固体燃料的自燃趋势，但它们的主要缺点是所需的金钱和时间。这项研究的目的是提出一种通过测量气体排放来检测固体燃料初期自燃的方法。这项研究比较了检测自燃趋势（例如TG，DSC或磁化率）以及与燃烧相关的气体排放结果的现有方法。已经使用了不同的方法来评估气体排放测试的结果，表明间隔和屈曲方法可提供对自热过程的早期检测。使用这种方法，可以使用每个工业设施中当前可用的设备预先确定此过程，从而降低成本并提高效率。
