“…An ideal fuel wood species should have high calorific value coupled with high wood density and low ash content. The results of the present investigation are in conformity with the earlier findings of Kumar et al, (2011), Purohit andNautiyal (1987) and Bhatt and Todaria (1992b).…”

“…To estimate the energy of wood samples, pellets of known weight (1gm) of plant material were burned in an oxygen bomb calorimeter (Bhatt and Bhadoni, 1990). For the estimation of ash content (%), 2 gm of ground sample was burned in a muffle furnace at 600 0 C for 3 hrs following the method given by Purohit and Nautiyal (1987) and Bhatt and Todaria (1992a).…”

“…Wood moisture content (%) was determined after drying it at 100±5 0 C for 48 hr (Bhatt and Badoni, 1990). Wood density (g/cc) was calculated using the water displacement technique (Purohit and Nautiyal, 1987). Wood samples were ground in a mechanical grinderand pelleted to determine their calorific values.…”

“…This parameter was a measure of the global properties of biomass as solid biofuel. FVI was related to important properties, such as the heating value, bulk density, and ash and moisture contents (Purohit and Nautiyal 1987;Cuvilas 2015;Ojelel et al 2015). The FVI is a more accurate volumetric energy density, because it quantifies the effect of the moisture and ash contents on the energy density of biomass (Díez and Pérez 2017 Figure 2 shows the mass yield of patula pine for the different torrefaction conditions.…”

The effects of torrefaction under an oxidizing atmosphere on the physicochemical properties of patula pine wood chips were studied. Raw and torrefied pine were characterized to evaluate the effect of temperature and residence time on biofuel properties, such as bulk density, equivalent Hardgrove grindability index (HGIeq), ultimate and proximate analyses, heating value, and fuel value index (FVI). In contrast, the torrefaction process was characterized by mass and energy yields, and by the energymass co-benefit index (EMCI). Torrefaction was performed in a rotary kiln at temperatures between 180 °C and 240 °C during residence times between 30 min and 120 min. The torrefaction process under an oxidizing atmosphere tended to increase the fixed carbon/volatile matter ratio (from 0.19 to 2.5), while the H/C and O/C atomic ratios decreased 73% and 55%, respectively. The best properties of wood reached in the experimental plan were obtained at 210 °C during 75 min. For this torrefaction condition, energy yield, FVI, and EMCI were 85.91%, 1.91 MJ/cm 3 , and 4.41%, respectively. Additionally, the lower heating value for torrefied pine (18.65 MJ/kg) was higher than for the raw material (17.76 MJ/kg), and the HGIeq was 17% greater, which resulted in a better grindability behavior.

“…The AGB was calculated in the parcel and the value was extrapolated to hectare. In order to compare the fuel characteristics of the four species, the Fuelwood Value Index (FVI) was estimated (see Table 1), following to Purohit and Nautiyal (1987). The basic density values of the species were determined from available literature (Vita et al, 1998;Bravo et al, 2006;INTI-CITEMA, 2007).…”

Argentina plans to reach from 3% to 10% biomass participation for the internal supply of primary energy for 2015. However, biomass exploitation requires detailed studies at a local level for territorial energy planning, to achieve the expected energy and environmental benefits. This study, performed in the north of Argentina (Lerma Valley, province of Salta) is a step in this direction. The objective was to identify, characterize and quantify biomass feedstock availability in the region and its energy supply, studying the demand and utilization alternatives; and building different methodologies of quantification. The feedstock examined includes agricultural waste (AWB), municipal solid waste (MSW), and woody biomass (three main ecosystems and four species of Acacias spp.). They are annually producing 17,800 t.yr -1 (equivalent to 206,000 GJ.yr -1 ) of AWB; 24,100 t.yr -1 (around 34,000 GJ.yr -1 as biogas) of MSW (wet weight) and 213,000 t.yr -1 (or 3.1 million of GJ.yr -1 ) of woody biomass. The Acacias constitute 74% of the Shrubland's potential bioenergy (213,000 GJ.yr -1 ). This report will make possible the application of realistic energy projects for the area, promoting efficient exploitation of resources and generating positive local impact. The main bottlenecks for the implementation of such projects and some possible strategic solutions are identified. The proposed methodologies might be used to other geographical regions, within programs of territorial energy planning. In addition, the new data set of available worldwide biomass resources and the scientific knowledge in the field of bioenergy that has been generated, both constitute fundamental contributions for bioenergy promotion.
