In a context where the depletion of traditional energy sources together with the emission reduction question reached a dead end, increasing attention is posed towards emerging technologies. Among such technologies, those for which energy is produced locally by residual biomass have gained in the last decades a role of first relevance. Today, different technologies can be successfully applied for distributed energy production from biomass. Gasification is the most promising because offers the possibility to achieve the highest net efficiency. Nevertheless, several questions need to be addressed to get this technology ready to market. The major drawback is related to the presence, in the produced gas, of tars and condensables that still greatly inhibits the application of this technology. The most common configuration for small scale applications is that where the syngas produced in a downdraft gasifier is feed, after its purification, in an internal combustion engine (ICE) for power production. In this work, a new configuration where syngas produced by downdraft gasifier is feed directly in an externally fired air turbine is discussed and numerically analysed. A numerical model of the whole process was built using an in-house code and results were evaluated in terms of first law efficiency. © 2018 AMSE Press. All rights reserved.
