The present project was conducted with the circumferential-fuel-jets inverse diffusion flame (CIDF) burner burning liquefied petroleum gas (LPG) enriched with 50% of hydrogen fuel (H2). The range of stable operation of the CIDF burner in terms of Reynolds number (from laminar to turbulent flow regions), equivalence ratio and fuel jet velocity of LPG of the 50% H2-LPG mixed fuel was identified. ...

Objectives • Research, develop, assemble, and test a 50 kW net polymer electrolyte membrane (PEM) fuel cell stack system comprised of a PEM fuel cell stack and the supporting gas, thermal, and water management subsystems. The PEM fuel cell stack system will be capable of integration with at least one of the fuel processors currently under development by Hydrogen Burner Technology (HBT) and Arth...

Rayleigh scattering temperature measurements were obtained in a turbulent reactive swirling coaxial jet discharged from a swirl-stabilized burner along the jet-flame centerline. They are reported up to 10 fuel nozzle diameters downstream of the burner exit at a Reynolds number of 29000. The effect of swirl numbers (S=0.3, 0.58, 1.07) on the temperature fields, the power spectral density of temp...

in studies done on porous burner, generally burners with axial flow are considered. in this paper, porous burners with radial and axial flow have been modeled numerically and results of radial and axial porous burners with equal fuel consumptions are compared. the mechanism used in combustion phenomenon is 15 stage mechanisms which predict the pollutions production precisely. the results show a...

The Jing Ltd. miniature combustion aerosol standard (Mini-CAST) soot generator is a portable, commercially available burner that is widely used for laboratory measurements of soot processes. While many studies have used the Mini-CAST to generate soot with known size, concentration, and organic carbon fraction under a single or few conditions, there has been no systematic study of the burner ope...

he GIF Technology Roadmap [1] identified the Lead-cooled Fast Reactor (LFR) as a technology with great potential to meet the small-unit electricity needs of remote sites while also offering advantages as a large system for grid-connected power stations. The LFR features a fast-neutron spectrum and a closed fuel cycle for efficient conversion of fertile uranium. It can also be used as a burner o...

The current work presents the results of an experimental investigation of gas-phase combustion synthesis of silica (SiO2) particles using a multi-element diffusion flame burner (MEDB, a Hencken burner). Silane (SiH4) was added to hydrogen/oxygen/argon (H2/O2/Ar) flames to produce SiO2 nanoparticles at various burner operating conditions ( 0.47–2.16). To characterize the burner performance, temp...

In this paper, the dynamic model of a fuel processor for hydrogen production from steam reformation is first introduced. The fuel processor is built according to an integrated burner and reformer bi-catalyst plate configuration. The model is then coupled with the one of a PEM fuel cell, and the overall simulator is used to analyze different control configurations. It is shown that the limited d...
