The Department of Energy’s River Protection Project (RPP) is tasked with retrieving highly radioactive waste from Hanford double-shell and single-shell tanks to provide feed for vitrification for long-term storage. Approximately 330,000 metric tons of sodium-rich radioactive waste originating from separation of plutonium from irradiated uranium fuel is stored in 177 underground tanks at Hanford...

The use of a plasma reformer for the generation of hydrogen rich gas from diesel fuel has been investigated. A system that is normally used for investigating natural gas reforming has been modified in order to investigate the reforming of heavy liquid fuels. The composition of the reformate has been investigated as a function of the composition of the reagents. The use of a one-step reformer/wa...

There is a substantial increase in energy demand in Turkey because of its growth of industrial development. Turkey’s present energy resources are insufficient and the need for energy is growing rapidly. Turkey does not possess enough conventional fossil fuel reserves, but possesses rich renewable energy resources such as hydraulic, solar, geothermal and wind. Among all, wind energy seems to be ...

In this paper, recent results of plasma processing of natural gas are described. The use of a plasma reformer for the generation of hydrogen rich gas from natural gas has been investigated. In an accompanying paper, progress in plasma reforming of diesel fuel is described. The reformate composition has been investigated as a function of the initial mixture of air and methane. High methane conve...

Simultaneous planar laser-induced incandescence, hydroxyl radical planar laser-induced fluorescence, and droplet Mie scattering are used to study the instantaneous flame structure and soot formation process in an atmospheric pressure, swirl-stabilized, liquid-fueled, model gas-turbine combustor. Optimal excitation and detection schemes to maximize single-shot signals and avoid interferences fro...

Improvements in diesel engine aftertreatment technology are needed to meet future environmental quality goals. Systems using recently developed compact plasmatron fuel converters in conjunction with aftertreatment catalysts could provide new opportunities for obtaining significant pollution reductions. Use of compact plasmatron reformers to produce hydrogen-rich gas for the regeneration of NOx ...

The first laboratory synthesis of hard materials such as diamond proceeded to attack of developing materials with high hardness to compete diamond. Boron rich solids are good candidates owing to their short interatomic bond lengths and strong covalent character. Boron containing hard material was synthesized by modifiedmicrowave method under nitrogen atmosphere by using a fuel (glycine or urea)...

The influence of wall heat loss on the emission characteristics ammonia-air swirling flames has been investigated employing Planar Laser-Induced Fluorescence imaging OH radicals and Fourier Transform Infrared spectrometry exhaust gases in combustors with insulated uninsulated walls over a range equivalence ratios, ?, pressures up to 0.5 MPa. Strong led quenching flame front near combustor at 0....

In the present work, methane, carbon monoxide, hydrogen and binary mixtures 20 % CH4–80 H2, 80 CH4–20 25 CO–75 H2 (by volume) were considered as fuels of a naturally aspirated port-fuel injection four-cylinder Volkswagen 1.4 L spark-ignition (SI) engine. The interest in these lies fact that they can be obtained from renewable resources such fermentation or gasification residual biomasses well e...

In this study, the features of fly ashes originating from industrial-scale high volatile bituminous coal combustion and co-combustion with 10% admixture alternative fuel SRF (solid recovered fuel) are presented, emphasis on organic petrographical characteristics. The mineralogical data co-evaluated geochemical data, aim to provide a full classification studied ashes, as well base information to...
