AB  - The actual paper analyses the performance of different energy crop biomasses, Miscanthus x giganteus Greef et Deu (EC-1) and Arundo donax L. (EC-2) stems, during slow pyrolysis process monitored by simultaneous TG-DTG-MS techniques, through chemical exergy analysis. In addition to considering the physical and chemical characteristics of given feedstocks for their efficient thermo-chemical conversion into pyrolytic gas, in this study, a theoretical simulation for their implementation use in the gasification process was also performed. The performed thermodynamic study with detailed exergy analysis showed that the large contribution of exergy in syngas components such as CO and H2 originates primarily from cellulose pyrolysis of EC-1, while large exergy contribution in syngas component as CH4 originates from lignin pyrolysis of EC-2. It was founded that the exergy efficiency of syngas for EC-1 equals 19.04%, which is lower than the exergy efficiency of syngas for EC-2 (20.46%), as a result of higher ash content in EC-1. Also, it was reported that higher carbon (C) and hydrogen (H) contents present in the EC-2 sample generate higher gaseous energy and exergy values, i.e. the increment of exergy efficiency of syngas, by both approaches (pyrolysis and gasification exergy analysis), but results in a lower biomass chemical exergy (18.28 MJ kg−1). The methodology applied to the gasification process was shown a higher exergy efficiency for EC-2 (∼36 – 42%) than for EC-1 (∼33 – 39%), dependant on the equivalence ratio (ER).

AB  - Pollutants originating from pulverised solid fuel combustion systems are investigated with a combination of
numerical simulations augmented by data from the fundamental experimental research. Nitrogen oxides formation
model, with fuel nitrogen as a main pathway mechanism, was implemented in the computational fluid dynamics model
for coal combustion. Partitioning of nitrogen contained in fuel is among the main characteristics influencing the final
production of pollutants, but it is highly dependent on fuel type and combustion parameters. The experimental
determination of intermediate chemical species during the pyrolysis of a coal sample was performed on a
thermogravimetric analysis-mass spectrometry system. The obtained results on the ratio of ammonia to hydrogen
cyanide during fuel nitrogen devolatilisation were used as input parameters in numerical simulations. The improved
model shows good results in simulating pyrolysis, making it suitable for modelling and optimisation of thermal
utilisation processes on industrial scales.
