AB  - Low-rank coal, characterized by its high moisture, ash, and volatile matter content, besides the significant contribution to GHG emission, can be challenging to combust efficiently. Biomass, on the other hand, is a renewable energy source that can enhance combustion performance and reduce emissions. The transition from fossil fuels to renewables should involve the co-combustion of coal and biomass which requires a detailed understanding of their individual and combined combustion kinetics. In this paper, the model-based kinetic modelling approach is applied to studying the thermal decomposition of coal and biomass using a combination of experimental data and mathematical models. By quantifying the rates at which various components of these fuels degraded and release heat, the optimization of process parameters, enhanced energy efficiency, and minimized environmental impacts could be achieved. The obtained results presented in the manuscript offers several advantages in comparison with the standard fuel characterization techniques. For example, the non-additive issues for different fuel characteristics could be overcome. Furthermore, the ability to predict combustion behaviour under different operating conditions, optimize burner designs, and develop cleaner combustion technologies could be enabled. In that sense, performed research in this paper could further supports the transition towards sustainable and carbon-neutral energy systems by harnessing the energy potential of low-rank coal while utilizing biomass as a clean and renewable co-fuel.

AB  - The fuel-NOx emissions during the conversion of carbon-based feedstock into energy and chemicals are on a global level in focus last decades due to environmental issues. The emission of nitrogen oxides is recognized among the other pollutants, as one of the key environmental problems related to energy production by various types of feedstocks. In this paper, the effect of fuel-based nitrogen delivery on the development of NOx precursors (HCN and NH3) during the devolatilization process of properly selected samples (coal, sawdust, wheat straw, and ground coffee waste) has been examined. TG-DTG thermal analysis techniques, coupled with mass spectrometry (MS) were used for the assessment of nitrogen distribution for HCN and NH3 gases, as intermediate species during feedstocks devolatilization, which directly influences the NOx emission during thermochemical conversion processes (pyrolysis and combustion). The mass balance of nitrogen together with performed EGA (evolved gas analysis), and the distribution of nitrogen between volatiles and formed char were also determined. The obtained data for investigated samples could be exploited for further thermochemical process optimization, in regard to NOx emissions. The presented results could be used as the experimentally determined input parameters for the mathematical modeling of indicated processes, and with further analysis can be transferred to large-scale industrial plant applications.
