Abstract:
Energy generation from renewable resources has grown in recent years due to the need to reduce the use of petroleum derivatives for economic and environmental reasons. Solid biofuels have proven to be an alternative for both electricity production and the transportation sector. To efficiently utilize these materials in their various applications, their characteristics must be understood. This study aims to map the melting temperature of ash in biomass samples. The methodology applied was based on the physical-chemical analysis of sugarcane bagasse and wood chips samples, using standardized methods. These materials were selected because they are the most widely used as a sustainable energy source. Ash is a solid residue formed in boilers during the combustion of materials and must have suitable properties, such as a melting temperature compatible with the process. The melting characteristics of ash are directly related to its chemical composition, since the presence of certain elements can impact the melting behavior of materials. A lack of information on this parameter can result in problems such as incrustations and unexpected interruptions in generation unit operations. Despite the importance of this topic, there is still a lack of scientific literature on the fusibility of ash from solid biofuels.
