Behavior of torrefied versus fresh woody pellets in a fixed-grate reactor: Comparison of combustion parameters and fouling and slagging tendency 2019 This study analyzes the conversion characteristics of two agricultural residues (vineyard and olive pruning) in form of pellets and draws a comparison with the same fuels submitted to a thermal treatment, i.e., torrefaction. The combustion characteristics are measured through the burning rate and temperatures reached. Afterwards, ash and its sintered fractions are studied to determine problems related to fouling and sintering that may cause clogging of mechanical parts in conversion equipment. The torrefied fuels have shown some improvement regarding ash behavior, especially, a reduction of sintered fractions. However, the behavior of both biomasses can be very diverse in some regards. Additionally, the results of predictive indices have proven inconclusive regarding the prediction of sintering and fouling problems. This highlights the complexity of agricultural biomass respect to forest biomass (e.g., pine) and the necessity to evaluate fuels from agricultural residues. info:eu-repo/grantAgreement/EC/H2020/636865/EU/Flexible Superheated Steam Torrefaction and Grinding of Indigenous Biomass from Remote Rural Sources to Produce Stable Densified Feedstocks for Chemical and Energy Applications/SteamBio This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 636865-SteamBio info:eu-repo/grantAgreement/ES/MINECO-FEDER/ENE2015-68809-R info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.155 2019 Engineering (miscellaneous) 2019 Computer Science Applications 2019 Computer Networks and Communications 2019 info:eu-repo/semantics/conferenceObject info:eu-repo/semantics/publishedVersion Zapata, S.
