Ignition and combustion characteristics of n-butanol and FPBO/n-butanol blends with addition of ignition improver

This is the dataset for the paper "Ignition and combustion characteristics of n-butanol and FPBO/n-butanol blends with addition of ignition improver." This research is supported by the European Union’s Horizon 2020 Research and Innovation programme (SmartCHP project, Grant Agreement No. 815259). In this study, the ignition and combustion characteristics of fast pyrolysis bio-oil (FPBO) are investigated in a combustion research unit (CRU), which mainly consists of a constant-volume combustion chamber. To fuel CRU with FPBO, n-butanol and 2-ethylhexyl nitrate (EHN) are used to improve the atomization and ignition properties of the fuel blends, respectively. In the first part of this study, an appropriate proportion of EHN additive into n-butanol is determined based on the balance between the ignition improvement and the amount of EHN addition. Then, the effects of FPBO content in FPBO/n-butanol blends with the same EHN addition are investigated. The effects of chamber wall temperature on the combustion are also studied.
