This study is aimed at the possibility of the fallen (waste) beech leaves usage as material for briquettes production. The main purpose of beech leaves briquetting in this study is the possibility of using it in small home combustion units, as partial substitute of wood. From the briquetting point of view, it is necessary to dry the leaves to approximately 15% of water content (it takes more than a month by free (natural) drying in an approximately 10 cm high layer inside a heated room). Beech leaves briquetting by automatic press is an easy process, but with diverse lengths of briquettes at the output (2-20 cm). Proximate and ultimate analyses of collected beech leaves were done. A briquette sample was subjected to thermogravimetric analysis, which shows the temperature ranges of drying and hemicellulose, cellulose and lignin decomposition. The determined temperature ranges correspond to those from other literature sources. Combustion tests proved the possibility of beech leaves briquettes usage as fuel in a small combustion unit. All limit values of the actual European standard EN 13240:2001 were met and some limit values of future European Standard Commission regulation (EU) 2015/1185 were met as well. Results of energy efficiency and mass concentrations of pollutants in the flue gas will differ with different stove and different stove settings. Due to the properties of the beech leaves briquettes (high mass fraction of ash and fast disintegration on the grate during the combustion process), it is appropriate, especially for long term use, to combine this kind of fuel with a conventional one.

Biomass stoves are not only popular, widespread and important sources of heat but are also not negligible sources of pollutants. The present study had two objectives in this field of research. The first one was to determine the difference between standard wooden and beech leaves briquettes flue gas composition during similar, standard home combustion conditions. The second objective was to determine the possibility of decreasing the mass concentration of pollutants contained in the flue gas produced by standard and alternative fuel combustion, i.e. wooden briquettes and beech leaves briquettes, by an oxidation catalyst. Significantly higher mass concentration of nitrogen oxides (NO x ), almost 2.5 times higher, in the flue gas was observed during the beech leaves combustion. Both fuels reached the edge of actual legislation limit (European Standard Commission regulation [EU] 2015/1185) in case of mass concentration of carbon monoxide (CO). This issue was solved by a palladium-based catalyst with average degree of conversion around 82%. The catalyst also influences flue gas composition from mass concentration of propane point of view with average degree of conversion around 15%. The mass fraction of sulphur, occurring in the beech leaves briquettes, did not cause any issue to the catalyst in terms of its degree of CO conversion. Due to the test results from the beech leaves briquettes, i.e. high mass fraction of ash and high mass concentration of NO x in the flue gas, it is appropriate to use this kind of fuel as secondary fuel during the co-combustion process.

Wood has the ash content below 1 wt% and the heating value is normally between 18 MJ/ kg and 20 MJ/kg (Ushakov et al, 2017). Any increase of the ash content with 1% determines the decrease of the heating value with 0.20 MJ/kg, since the ash does not substantially contribute to the heat developed during combustion, even if some mineral elements from the ash may represent catalysts for the thermal decomposition of the fuel (Ushakov et al, 2017).…”

IntroductionCurrently, fossil fuels, such as oil, coal or natural gas are the main energy sources, which is approximately 80% of the annual total energy consumption (Krajnc, 2015). As estimated, these energy sources will deplete in the coming next 40-50 years; that is why new energy sources need to be discovered and employed. Among new energy sources there are the renewable energy sources such as geothermal energy, wind energy, solar energy, and the energy of lignocellulosic biomass. Biomass is the generic name for any organic substance, derived from plants, being the result of photosynthesis. The general category of biomass includes wood from forests, agricultural crops, marine algae, leftover from agricultural and forestry processes, industrial, human and animal residues and organic manure etc.Wood biomass is a part of renewable energy sources and generally comprises remains of wood in different forms and dimensions. Wood has the ash content below 1 wt% and the heating value is normally between 18 MJ/ kg and 20 MJ/kg (Ushakov et al., 2017). Any increase of the ash content with 1% determines the decrease of the heating value with 0.20 MJ/kg, since the ash does not substantially contribute to the heat developed during combustion, even if some mineral elements from the ash may represent catalysts for the thermal decomposition of the fuel (Ushakov et al., 2017). In addition, the increase of the ash content has an effect on the proportional decrease of the carbon content, the latter being the chemical element that determines the increase of the heating value of wood. Furthermore, they reported that any increase of the carbon content with 1% increased the heating value (0.39 MJ/kg). This result was obtained for the fuel wood from heavy species, such as beech and hornbeam. The cellulose has a lower heating value (17.3 MJ/kg) than lignin (26.7 MJ/kg) because of the higher degree of oxidation (Ushakov et al., 2017). As compared to the fossil coal, the carbon dioxide emissions coming from the combustion of biomass are decreased by 93%. Moreover, the alkaline ash derived from biomass retains a part of the sulfur dioxide and carbon
