Flame Speed Characteristics of Syngas (H2-CO) with Straight Burners for Laminar Premixed Flames
Laminar flame speeds of undiluted syngas (H2/CO) mixtures have been studied at atmospheric conditions using chemiluminescence and schlieren techniques for a straight cylindrical burner apparatus. A wide range of mixture composition, from pure H2 to 1/99 % H2/CO, has been investigated for lean premixed syngas flames. To achieve a better flame stabilization and reduce flame flashback propensity, ...
متن کاملA New Type of Steady and Stable, Laminar, Premixed Flame in Ultra-Lean, Hydrogen-Air Combustion
Ultra-lean, hydrogen-air mixtures are found to support another kind of laminar flame that is steady and stable beside flat flames and flame balls. Direct numerical simulations are performed of flames that develop into steadily and stably propagating cells. These cells were the original meaning of the word “flamelet” when they were observed in lean flammability studies conducted early in the dev...
متن کاملAn Investigation of Fuel Mixing and Reaction in a CH4/Syngas/Air Premixed Impinging Flame with Varied H2/CO Proportion
For industrial applications, we propose a concept of clean and efficient combustion through burning syngas on an impinging burner. We performed experimental measurements of particle image velocimetry, OH radical (OH*) chemiluminescence, flame temperature, and CO emission to examine the fuel mixing and reaction of premixed impinging flames of CH4/syngas/air with H2/CO in varied proportions. The ...
متن کاملLaminar burning velocity of natural gas/syngas-air mixture
This study suggests the equimolar mixture of Natural Gas (100% CH4) and Synthesis Gas (40% H2 + 40% CO + 20% CO2) as an alternative to reduce hydrocarbons consumption and reduce pollutant emissions. As a key parameter to characterize this combustible mixture, the laminar burning velocity was studied based on numerical simulations and experimental measurements in fl ames generated using a contou...
متن کاملA Laminar Vortex Interacting with a Premixed Flame: Measured Formation of Pockets of Reactants
A single toroidal, laminar vortex in created and a laminar premixed flame is propagated over the vortex in order to study the fundamental interaction process and to compare results with the numerical solutions of the Navier-Stokes equations obtained by Poinsot, Veynante, and Candel. Results quantify the degree of flame rollup, the flame perimeter increase due to wrinkling, the minimum vortex si...
