This paper addresses the design, development and experimental tests of a prototype fuel gas generation system based on biomass gasification for small-scale applications, around 5 kW. It comprises small scale downdraft gasifier cleaning aiming to clean-up producer be used in upstream Internal Combustion Engine (ICE). The design follows methodologies that have been reported available literature. ...

In this paper design and fabrication of compact fluidized bed gasifier with increased gas – solid interaction is proposed for automotive vehicle. The aim of the design is generate a nitrogen (N2) free product gas with low tars and fines content. Firstly a compact size gasifier with fluidized bed is designed and after that it fabricated. Design was done with the help of CATIA design/modeling sof...

Abstract Purpose This study aimed to determine whether ammonia can genuinely help reduce the carbon footprint of maritime activities. Given this, it was decided investigate life cycle and its impact on environment regarding global warming potential. Methods To achieve this goal, parametric trend assessment applied yield a general reliable observation. The research combined with comprehensive da...

This study presents a summary of the properties of deep convective updraft and downdraft cores over the central plains of the United States, accomplished using a novel and now-standard Atmospheric Radiation Measurement Program (ARM) scanning mode for a commercial wind-profiler system. A unique profilerbased hydrometeor fall-speed correction method modeled for the convective environment was adop...

Wood and forestry residues are usually processed as wastes, but they can be recovered to produce electrical thermal energy through processes of thermochemical conversion gasification. This study proposes an equilibrium simulation model developed by ASPEN Plus investigate the performance 28 woody biomass residues’ (WB&FR) gasification in a downdraft gasifier linked with power generation unit...

Observations are reviewed that show that the dominant kinematic elements of the supercell rear flank are a downdraft trailing an adjacent updraft, a gust front, and counter-rotating vortices embedded in the gust front convergence zone. The associated vortex lines are shaped like arches. In an idealized simulation of the evolution of this flow structure, vortex rings are observed to form around ...
