“…Namely, Bondrea et al [17] reported the necessary pressure for atomization at the level of 14 bar. The lowest energy demand (i.e., Etotal 320 kJ/kg) was observed by Lasek et al during micro wax combustion [22]. Except for the Bondrea et al [17] study, the power loss is less than 2% (i.e., in the range of 0.73-1.94%).…”

“…The combustion tests were carried out using a technical-scale combustion chamber (height of 3.4 m and internal diameter of 0.6 m), which was used in previous research [22]. The three main parts of the installation are the combustion chamber with burners, a high-temperature precipitator, and an exhaust gas cooling system.…”

“…The average specific heat of crude oil is in a similar range of 2.2 kJ/kgK [40]. The properties of micro wax were taken from [22,41,42] (heat capacity [41,42] c p at a level of 2.5 kJ/kgK). The specific heat of HFO was assumed on a similar level.…”

Liquid biofuels are of special interest due to the possibility of their application as a substitute for fossil liquid fuels. The necessary step is to investigate the possibility of bio-fuel application in terms of its properties and similarities to fossil liquid fuels (e.g., crude oil, heavy fuel oil, diesel). The properties and combustion performance of heavy fuel oil (HFO) and products of the fatty acids distillation residues (FADR) were analyzed in this study. The application of animal-fat-delivered fuels is fully suggested in the literature. Nevertheless, the investigations focused on the raw materials or their transformation into diesel. The novelty of this paper is the utilization of FADR as a substitute for HFO. The utilization of FADR allows the use of this material as a feedstock to obtain valuable products (fuel) and avoids generating waste after animal fat processing. The experimental investigations were carried out using a technical-scale 150 kWth combustion chamber. FADR can be recognized as a substitute for HFO due to its beneficial calorific properties and viscosity. Other beneficial effects are the significantly lower emission of SO2 (lower than 1 ppm) and PAHs (i.e., 355 µg/m3n) during the combustion of FADR. Finally, the application of FADR requires less energy demand for fuel heating and pressurization.

“…(Urbaniak et al 2007). Waxes are long-chain hydrocarbons heavier than C 20 , and those have between 20 and 36 carbon atoms are considered as light waxes (the boiling point between 300 °C and 500 °C) and those with more than 36 carbon atoms are heavy waxes (Lasek 2018). Several authors reported the oil and wax mixture existed jointly because waxes usually contain liquid hydrocarbons dissolved or vice versa the liquid hydrocarbons contain waxes (Lopez et al 2017).…”

Background In this study, pyrolysis of low-density polyethylene (LDPE) and LDPE with aluminum (C/LDPE) wastes was carried out with different heating rates (5-10-20°C/min) at different temperatures (400-600-800°C). The effect of temperature and heating rate on liquid product yield was investigated. Product yields of LDPE and C/LDPE wastes were compared, and optimum liquid products were analyzed to utilize as commercial waxes for future use. Methods To determine the parameters of pyrolysis wastes was investigated with proximate, elemental analysis, and TGA. The as-produced liquid from pyrolysis of wastes was characterized by different characteristic tools, such as elemental analyses, GC-MS analyzes, 1H-NMR tests, FT-IR spectra, the density, melting point, and carbon residue to compare commercial waxes. The characterization process was continued for the parameters with the optimum liquid products. Results As a result of pyrolysis, the highest liquid product yield was achieved at 800°C with 5°C/min heating rate (85.87 %), and at 600°C with 5°C/min heating rate (71.3 %) for LDPE and C/LDPE, respectively. The results indicated that the derived liquid products are similar to commercial heavy wax.
