Molecular weight growth pathways in fuel-rich combustion
… when a hydrocarbon fuel is oxidized under fuel-rich conditions. The distinction between what constitutes the largest P AH molecule and the smallest soot particle is arbitrary; the formation processes of both can be placed under the heading of molecular weight growth. Evidence exists for the …

FUEL NITROGEN CONVERSION DURING FUEL RICH COMBUSTION OF PULVERIZED COAL AND CHAR
… char nitrogen has been investigated during fuel rich combustion. The experiments were done with the objective of clarifying the roles of NO, HCN, and NH₃, and char nitrogen in the post-combustion gases in the first, fuel rich stage of a staged combustor. The experimental apparatus includes a …

Fundamental studies in hydrogen-rich combustion : instability mechanisms and dynamic mode selection
Hydrogen-rich alternative fuels are likely to play a significant role in future power generation systems. The emergence of the integrated gasification combined cycle (IGCC) as one of the favored technologies for incorporating carbon capture into coal-based power plants increases the need for gas …

Novel method for carbon nanofilament growth on carbon fibers
… in which carbon structures are grown from fuel rich combustion mixtures on certain catalytic metals, multiscale filament structures were grown from ethylene/oxygen mixtures at 550 °C on commercial PAN and pitch carbon fibers. The filaments grew in a bimodal size distribution. Relative short, …

Syngas production from heavy liquid fuel reforming in inert porous media
… limit of hydrocarbon/air mixtures, the rich combustion experiments have been carried out in a two-layer porous medium combustor, which stabilises a flame at the matrix interface and recirculates the enthalpy of the hot products in order to enhance the reaction rates at ultra-rich …

Size Controlled Metal Oxide Nanoparticles:Synthesis, Characterization, and Application to Catalysis
… the nano-size nuclei core for particle growth in combustion process, a flow reactor was built to investigate the effect of metal oxide nanoparticles on the formation of soot in fuel-rich combustion. The synthesis of copper oxide nanoclusters was carried by calcination of silica impregnated with …

Oxygen permeation and thermo-chemical stability of oxygen separation membrane materials for the oxyfuel process
… consists in the burning of coal in an oxygen-rich atmosphere to produce a flue gas highly concentrated in CO2, is a technology considered for zero CO2 emission coal-fired power plants. The production of this O2-rich combustion gas from air can be carried out using high purity oxygen separation …
