The paper presents an analysis on small systems for converting biomass/wastes into power using Micro Gas Turbines (MGT) fed with gaseous bio-fuels produced by airgasification. The MGT is designed for burning various fossil liquid and gas fuels, having catalogue data related to natural gas use. Fuel switch changes their performances. The present work is focused on adapting the MGT for burning al...

A visualization facility has been developed at Stanford University in order to study flow in a turbulent combustion boundary layer. The motivation for the facility arises from recent studies of fast burning fuels for hybrid rocket propulsion where droplet lift-off from the melting fuel surface is the dominant mass transfer mechanism. The facility, shown in Figure 1, has been used to image the c...

In order to use gaseous fuels in Diesel Engines, Dual-Fuel Diesel Engine (D. F. D. E) the pilot injection approach is chosen. To predict its performance, an engine cycle model, based on limited-pressure Diesel cycle, is constructed. The model predicts D. F. D. E performance with LPG, and CNG gases. Comparing with pure Diesel engine, by increasing gas proportion in dual-fuel, indicated power and...

Anaerobic digestion plays a starring role in the development of bioeconomy due to practical advantages that gaseous fuels have over solid (i [...]

The potential effects on the health of future generations of humans, and other mammals arising from the increase in the concentration of carbon dioxide in the atmosphere, resulting from the use of large amounts of fossil fuels by industrialized societies, is considered. It is concluded that the change in the gaseous composition of the atmosphere will lead to a decline in the health of humans an...

Conversion of biomass into biofuels (gaseous and liquid fuels) can be achieved primarily by biochemical and thermochemical processes [2]. Although biochemical technologies are well developed and widely used for biofuels production [3], however, the types of biomass can be used are limited. Thermochemical gasification appears to be a promising technology that can exploit the embedded energy with...

1. Bioenergy electricity and any solid, liquid or gaseous fuel that is produced through the processing of biomass may provide an alternative to the expansion of fossil fuels consumption. With careful strategies and under appropriate regulatory frameworks, bioenergy, and in particular biofuels, may be instrumental to slowing down the process of global warming and enhancing energy security, as we...

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can be used as gaseous fuels and they may contain different amounts of light hydrocarbons. This paper presents the combustion results obtained with a Cu-...
