The article directly and indirectly refers to anthropological and philosophical texts which strive to discover and present the gender factor as important in the light of the humanities. The author refers to “Literackie nie-nazywanie. Onomastykon polskiej prozy współczesnej” (Literary Not-naming. Onomasticon of the modern Polish prose) by Magdalena Graf and indicates the femininity factor as a relevant one also in onomastics.

The motivation of this work was to define the reburning potential of sewage sludge gasification gas (syngas). Numerical simulation of co-combustion process of syngas in hard coal-fired boiler has been done. All the calculations were performed using the Chemkin program. Plug-Flow Reactor model was used. The calculations were modelled using GRI-Mech 2.11 mechanism. The highest NO conversions are obtained at the temperature of about 1000-1200 K. The highest reduction efficiency was achieved for the molar flow ratio of syngas equal to 15%. The combustion of hard coal with sewage sludge - derived syngas reduces NO emissions and the amount of coal needed to produce electricity and heat. Advanced reburning, which is a more complicated process gives efficiency of up to 80%. The calculations show that the analyzed syngas can yield better results.
