The Temperature and Pressure Dependencies of Propagation Characteristics for Premixed Laminar Ethanol-Air Flames
Laminar burning velocity is strongly dependent on mixture characteristics, e.g. initial temperature, pressure and equivalence ratio. In this work, spherically expanding laminar premixed flames, freely propagating from a spark ignition source in initially quiescent ethanol-air mixtures, have been imaged and then the laminar burning velocities were obtained at initial temperatures of 358 K to 500...
متن کاملSoot inception limits in laminar diffusion flames with application to oxy–fuel combustion
For diffusion flames, the combination of oxygen enrichment and fuel dilution results in an increase in the stoichiometric mixture fraction, Zst, and alters the flame structure, i.e., the relationship between the local temperature and the local gas composition. Increasing Zst has been shown to result in the reduction or even elimination of soot. In the present work, the effects of variable Zst o...
متن کاملAxial Dispersion Modeling of Laminar Flames
The reduction of nitrogen oxides (NOx) emissions from an existing burner is a a challenging task requiring the understanding of interactions between burner geometry and flame aerodynamics. Currently, three approaches for NOx control exist: fuel or flue gas treatment and combustion modifications. Low NOx burner design is economically attractive for natural gas and light fuel oil combustion since...
متن کاملCombustion characteristics of primary reference fuel (PRF) droplets: Single stage high temperature combustion to multistage •Cool FlameŽ behavior
We report experiments and detailed numerical modeling of mixtures of primary reference fuel (PRF) droplets consisting of n -heptane and iso -octane with initial droplet diameters of 0.5 and 3.51 mm. The results show a quasi-steady, low temperature (or “Cool Flame” ( CF )) droplet burning mode that stems from a varying two-stage chemical kinetic behavior of the combustion chemistry. The simulati...
متن کاملSoot Formation in Laminar Diffusion Flames
Laminar, sooting, coflow diffusion flames at atmospheric pressure have been studied experimentally and theoretically as a function of fuel dilution by inert nitrogen. The flames have been investigated with laser diagnostics. Laser extinction has been used to calibrate the experimental soot volume fractions and an improved gating method has been implemented in the laser-induced incandescence (LI...
