- SSF-made Pd@TiO2 Nano Catalysts
-
The titania supported palladium nano catalysts (Pd@TiO2) are synthesized in one-step using a premixed stagnation swirl flame (SSF) with ultra-fine spray system. This novel SSF method, with features of short residence time and fast quenching, produces nanosized (< 2.5 nm) palladium particles being well dispersed on the 7-8 ...

- Dipole–dipole interaction of NPs
-
The interactions between nanoparticles in high-temperature vapor-synthesis environments have important implications on their self-assembly into specific structures. We apply classical molecular-dynamics (MD) simulations, with the interatomic potential, to study the interaction forces and the resulting dynamics between pairs o...

- Particulate Formation and Ash Deposition of Oxy-Co
-
The characteristics of both particulate formation and ash deposition play an important role in retrofitting the conventional air-fired coal power plant into the recycled oxy-fuel plant. An intensively comparative study was performed with a 25 kW quasi one-dimensional down-fired pulverized coal combustor for clarifying the dif...

- Dynamic behavior of Na in combustion
-
We examine the dynamic behavior of sodium (Na) release during the pulverized coal combustion of Zhundong lignite using a laminar, Hencken flat-flame burner technique. By subtly utilizing the gap between the excitation energies of the gas and particle phases, a new low-intensity laser-induced breakdown spectroscopy (LIBS) is d...

- Diagnostic of V-Ti doping nanoparticle synthesis
-
Flame synthesis of V-doping TiO2 is studied by in-situ diagnostic of phase selective laser-induced breakdown spectroscopy (LIBS). We apply this novel optical spectroscopy to tracing the gas-to-particle phase transition of V and Ti species, as low-intensity laser only excites V and Ti present inthe particle phase but not in th...

- Dynamic Behavior of Biomass Ash Deposition
-
The severe fouling and slagging problem due to high alkali and alkaline earth metal content still limits the applications of self-sustained biomass power plants. It is essential to study dynamic behavior of ash deposition in pure biomass combustion. Three kinds of biomass, saw dust, wheat straw and corn stover, were burned in...
