L’applicazione della fire protection engineering nell’analisi antincendio del complesso monumentale del S. Maria della Scala in Siena
No full textIn contesti architettonici complessi può risultare estremamente difficile, specialmente nel caso di realizzazione di nuove attività, l'applicazione di normative antincendio di tipo deterministico, che rischiano, di fatto, di limitare le posibilità di recupero. Una corretta applicazione della fire engineering, in particolare per complessi monumentali estremamente articolati come quello in esame (Santa Maria della Scala in Siena) permette di avvalorare e verificare le ipotesi progettuali. Il lavoro presenta un'applicazione innovativa della fire engineering che oltre a fornire un supporto alle richeiste di deroga normativa offre importanti indicazioni progettuali per il recupero
Influence of fertilisation and harvest time on fuel quality of giant reed (Arundo donax L.) in central Italy
No full textThe perennial grass giant reed (Arundo donax L.) has been proposed as a promising biomass energy
crop in southern Europe. The aim of this study was to investigate the effects of two fertilisation levels
(F = 200–80–200 N–P–K kg ha−1; UF = 0–0–0 N–P–K kg ha−1) and two harvest times (A: autumn, W: winter)
on the biomass quality of giant reed as a solid fuel for combustion. Different aged crops grown in
central Italy (latitude 43◦40N, and longitude10◦19E) in the period of 1996–2005 were collected and
analysed. Our results confirmed that giant reed biomass is characterized by a high content of ash and
silicon. Giant reed showed an increase in ash content from F to UF and from A to W. The production
of biomass from fertilised crops harvested in the autumn may thus be a good method for reducing the
ash content by about 20%. The results also showed an improvement in biomass combustion quality in
10-year-old crops due to a lower ash content and higher SiO2/K2O and CaO/K2O ratios, which could contribute
to a lower slagging tendency. This research should help to improve our knowledge of the chemical
composition of giant reed and presents possible agronomic strategies to combine a high biomass yield
with good combustion quality
Comparison of Arundo donax L.. and Miscanthus x giganteus in a long-term field experiment in central Italy. Analysis of productive characteristics and energy balance
No full textMiscanthus x giganteus (miscanthus) and Arundo donax L. (giant reed) are two perennial crops which have been received particular attention during the last decade as bioenergy crops. The main aim of the present study was to compare the above-ground biomass production and the energy balance of these perennial rhizomatous grasses in a long-term field experiment. The crops were cultivated from 1992 to 2003 in the temperate climate of Central Italy with 20,000 plants ha-1, 100–100–100 kg N, P2O5, K2O per hectare, and without irrigation supply. For each year of trial, biomass was harvested in autumn to estimate biometric characteristics and productive parameters. Besides, energy analysis of biomass production was carried out determining energy output, energy input, energy efficiency (output/input) and net energy yield (output–input). Results showed high above-ground biomass yields over a period of 10 years for both species, with better productive performances in giant reed than in miscanthus (37.7 t DM ha-1 year-1 vs 28.7 t DM ha-1 year-1 averaged from 2 to 12 years of growth). Such high yields resulted positively correlated to number of stalks (miscanthus), plant height and stalk diameter (giant reed). Moreover, these perennial species are characterised by a favourable energy balance with a net energy yield of 467 and 637 GJ ha-1 (1–12 year mean) for miscanthus and giant reed respectively. With such characteristics, both grasses could be proposed as biomass energy crops in Southern Europe with a significant and environmentally compatible contribution to energy needs
Long term evaluation of biomass production and quality of two cardoon (Cynara cardunculus L.) cultivars for energy use
No full textCardoon (Cynara cardunculus L.) is an herbaceous species indicated as one of the most suitable energy crop for southern European countries. The aim of this work was to outline the productivity of two cardoon cultivars, Bianco Avorio (BA) and Gigante di Romagna (GR), over 11 years of cultivation in rain fed field conditions in the temperate climate of Central Italy. The quantitative and qualitative aspects of its biomass (calorific value, ultimate and proximate analyses, ash composition) as well as its energy balance (energy efficiency, net energy yield) have been determined. Crop dry yield was not different between the two cultivars and it was rather stable with a mean value (averaged from year 3 to 11) of 14 and 13 t ha-1 for GR and BA respectively. Furthermore the biomass dry matter content was higher in BA than GR (51% vs 42%). The chemical analysis of cardoon biomass showed a similar composition in both cultivars with good calorific value (15 MJ kg-1) but with an ash content (13.9% d.w.) higher than other herbaceous energy crops. The total energy input was higher in the establishing than in the following years, however from the planting year onward, both cardoon crops were characterised by a positive energy balance. Even if its mean net energy is lower than other perennial energy crops (182 GJ ha-1 year-1), cardoon can be easily propagated by seed with important advantages for crop management and production costs.
The results confirmed cardoon’s good biomass yield and favourable energy balance even in cultivation systems characterised by limited water input. Moreover, future works are necessary in order to improve cardoon biomass quality and to evaluate the possibility of using it in blends with other biomass sources
