Biomass gasifiers convert the solid biomass to Producer gas that can be used for thermal, mechanical and electricity production. This paper deals with proximate and ultimate analysis of a number of biomass feed stocks like sawdust, pine wood, sal wood, eucalyptus and popular wood. These fuels have been used for the operation of 5 kW biomass gasifier installed at AHEC for electricity production ...

Extending the wealth accumulation model of Piketty and Zucman [2014] to include net depreciation in fossil fuels, minerals, and forests produces two key indicators: the net national saving rate adjusted for natural capital depreciation, and the ratio of this rate to long-run growth. These indicators are applied to eight rich economies over 1970–2013 and developing countries for 1979–2013. Where...

Dendromass remains the largest biomass energy source today. Dendromass has a lot of advantages in comparison with fossil fuels. One important benefit is reduced SO2 and NOx formation through a decrease in fuel bound sulfur and nitrogen respectively. One of applications of dendromass are wood pellets. Using of additives can affect some properties of wood pellets include combustion and production...

Life-cycle inventory (LCI) data are needed to scientifically document the environmental performance of materials for applications as governed by the many new green building standards, purchasing guidelines, and energy and climate change policy issues. This study develops the LCI data for particleboard, a composite wood panel product comprised of wood particles, urea–formaldehyde resin, wax, and...

We study the interplay of intertemporal risk management and saving decisions. We define risk management broadly by allowing the activity to influence the severity of loss, the probability of loss, or both simultaneously. Due to the similar cost-benefit structure of risk management and saving decisions a substitution effect arises whose implications are analyzed for changes in income and backgro...

Agricultural producers are interested in using biomass available on farms to substitute fossil fuels for heat production. However, energy crops like reed canary grass contain high nitrogen (N), sulfur (S), potassium (K) and other ash-forming elements which lead to increased emissions of gases and particulate matter (PM) and ash-related operational problems (e.g., melting) during combustion. To ...

The aim of this chapter is to show how thermooxidative properties of biological fuels can be evaluated by pressure differential scanning calorimetry (PDSC) and used to correctly classify the fuels studied. The onset oxidation temperature (OOT) is an important parameter for estimating the oxidation stability that can be evaluated by the ASTM method. Nevertheless, in addition to the OOT, other me...

Life-cycle inventory (LCI) data are needed to scientifically document the environmental performance of materials for applications as governed by the many new green building standards, purchasing guidelines, and energy and climate change policy issues. This study develops the LCI data for medium-density fiberboard (MDF), a composite wood panel product comprised of wood fibers, urea– formaldehyde...

Two energy-generating technologies in Britain which transform waste into a resource are compared. One is the (in)famous Combined Heat and Power incinerator in Sheffield, the other a forgotten biological digester in Devon utilizing anaerobic microbes. Both sites are early exemplars of experimental and biopolitical waste disposal technologies—incineration and Anaerobic Digestion—now regarded as l...
