“…Bioenergy accounts for up to two-thirds of all RES in Europe, and it grows at a rate similar to that of all the other sources combined (AEBIOM, 2015). Another consequence of this is an increased scientific interest in lignocellulosis biomass, resulting in abundant literature on the subject (Mitsui et al, 2010;Weger et al, 2013;Sabatti et al, 2014;Manzone et al, 2015;Stolarski et al, 2015b;Matyka and Kuś, 2016).…”

A b s t r a c t. Perennial energy crops are a source of the biomass used to generate energy. The aim of this study was to determine the chemical and thermophysical parameters of short rotation woody crops (black locust, poplar and willow), depending on soil enrichment practice (mineral fertilisation, lignin and mycorrhiza), in three-and four-year harvest cycles. In the study, the thermophysical properties and elemental composition of the biomass were determined. All analyses were performed in triplicate according to the standards. The fresh black locust biomass had the lowest moisture content, which resulted in the best lower heating value (10.16 MJ kg -1

“…[3], eucalyptus (Eucalyptus spp.) [4] and, to a lesser extension, black locust (Robinia pseudoacacia) [5]. All of them are a fast-growing tree plantations and therefore, a promising source of biofuel with a large potential to feed the demand of raw materials from the energy sector and other conventional industrial purposes [6].…”

“…The lack of knowledge about the expectable combustion behavior of energy crops is even more important for willow and black locust. Although their agronomic characteristics have been widely studied [3,5,14,17,23,24], there is yet a lack of information regarding their physical and thermochemical combustion-related properties.…”

Abstract:The physical and thermochemical properties of three short rotation forestry crops (poplar, willow and black locust) have been determined and compared in order to evaluate their suitability (energy potential and combustion-related operation problems) to be used in energy devices. The planting density was 6666 in a rotation of four years and the analysis were performed at the end of the first rotation. The three species showed significant differences regarding production, moisture and ash content, heating value and bulk density. The results obtained allow to establish priorities between species according to the expectable combustion behavior, willow being the most appropriate. Results indicate no problems related to SO x and NO x emissions. Moreover, the alkali metals determined in the fuel together with the chlorine content suggest no operation problems related with fouling or harmful corrosion.

“…Heat transfer coefficient is actually the inverse of the thermal resistance (Table 1). Therefore, the higher its value, the better thermal insulation properties material or structure has (Sharma et al 2015;Manzone et al 2015). External cladding of housing units is also formed by windows and doors.…”

Jobbágy J., Krištof K., Andacký M. (2016): The effectiveness of heating of housing unit by renewable energy source. Res. Agr. Eng., 62 (Special Issue): S34-S43.The paper is aimed at pointing out possibilities of using of dendromass for heating. The object of interest was heating of housing units with 75.27 m 2 of total area. The average value of dendromass moisture was 17.71%. The inserted fireplace Nordica Focolare 70 with a nominal output of 9 kW was used as a heat source. For temperature measurement, a non-contact infrared thermometer GM 900 was used. The total heat loss transferred through walls of housing unit (heat loss through thermal bridges and ventilation losses) were calculated at the value of 176.26 W/K. Based on the results of samples moisture the net calorific value of one kilogram of burned fuel wood was determined (14.791 MJ kg). The amount of thermal energy which is necessary to supply by the heating system for the whole heating period was 14,199.18 kWh. The weight of raw fuel wood was 5,450.97 kg (at moisture of 30%), dried at 17.71% (4,636.87 kg). Price of raw fuel wood of acacia for the year under evaluation was 64.80 €/m 3 (the required amount of raw fuel wood for heating period was 10 m 3 ). Total costs for the heating season was thus 648 €. The price of heat transmitted by the fireplace inset Nordica Focolare 70 inserted into heating system using fuel wood (white acacia) with 17.71% of absolute moisture was 0.045636 €/kWh.
