Available in PDF, EPUB and Kindle. Book excerpt: The effects of pressure, inlet air temperature, and fuel type on the soot threshold or critical equivalence ratio, are presented. Higher pressures yield lower soot thresholds, while no dependence on fuel type, as described by either the fuel hydrogen-to-carbon ratio, fuel molecular weight, number of carbon atoms, or number of carbon-carbon bonds, is observed. Variations in inlet air temperature have a complex effect; however, the results clearly show that the experimentally measured flame temperature is central to a description of the incipient soot formation process. The critical equivalence ratio dependence on pressure and temperature is shown to agree with a two-step semi-global model for soot precursor evolution for pressures form 0.1 to 0.8 MPa, and measured flame temperatures between 1600 and 2400K. The effects of equivalence ratio, pressure, and fuel chemistry on total non-luminous flame radiation were also studied. Radiant intensity was highest for an equivalence ratio of unity and increased linearly with pressure from 0.4 to 0.8 MPa. Keywords: Incipient soot formation, Flame radiation and emissivity, Premixed flames, Pressure dependence.

This book was released on 2012-10-29 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: With regard to both the environmental sustainability and operating efficiency demands, modern combustion research has to face two main objectives, the optimization of combustion efficiency and the reduction of pollutants. This book reports on the combustion research activities carried out within the Collaborative Research Center (SFB) 568 “Flow and Combustion in Future Gas Turbine Combustion Chambers” funded by the German Research Foundation (DFG). This aimed at designing a completely integrated modeling and numerical simulation of the occurring very complex, coupled and interacting physico-chemical processes, such as turbulent heat and mass transport, single or multi-phase flows phenomena, chemical reactions/combustion and radiation, able to support the development of advanced gas turbine chamber concepts

Book excerpt: Soot production in gas turbine combustors is not desirable since it is the major source of exhaust smoke emission and its thermal radiation to the combustor liner deteriorates the liner durability. Soot formation involves comparatively slow chemistry and equilibrium can not be applied to soot modelling in the combustor flow field. . The exact sooting process in the combustor is poorly understood given both the complexity and the limited experimental data available. The work reported in this thesis seeks to first develop in-situ techniques for retrieving spatially-resolved soot properties, mainly soot particle volume fraction, from within the combustor and also to apply the measured results to comparisons with predicted soot concentrations. Two probing methods have been demonstrated which also incorporate a laser absorption technique. The sight probe proves to be more reliable in the present measurements. The evaluation of the physical probing techniques in sooty laboratory flames reveals that the flame structure will not be substantially distorted by the probe. The disturbance caused by the probe is localised, a feature which is evident in the reported water flow visualization test. The necessary inert gas purge can be minimised to reduce the local aerodynamic perturbation. The measured soot volume fraction distributions are comparable with sooting levels reported in flame studies in the literature. The peak soot volume fractions are located off-axis, characteristic of the fuel atornization. The measurementsin the primary zone are restricted by the multi-phase character of the flow, where soot absorption can not be readily discriminated from fuel droplet scattering. Measurements are reported over a range of air-fuel ratios, inlet pressures and temperatures.

Download or read book Fundamentals of Soot Formation in Gas Turbine Combustors written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental facility for studying soot formation in high temperature, fuel-rich, laminar, premixed flames has been constructed. Diagnostics included laser absorption, thermocouple particle densitometry, and thermophoretic soot sampling with analysis by transmission electron microscopy. Single particles with diameters as small as 3-5 nanometers were observed. Larger particles (20-25 nanometers) agglomerated to form large clusters. A coflow, axisymmetric, laminar ethylene diffusion flame has been studied, both experimentally and computationally. A lifted flame has been selected to eliminate possible uncertainties caused by the burner lip. A two-dimensional, detailed soot growth model in which the equations for particle production are coupled to the flow and gaseous species conservation equations has been used to investigate soot production in the flame. Detailed transport and finite rate chemistry in the gas phase was coupled with the particle aerosol equations in the sectional representation. In comparison to measured data obtained using intrusive and non- intrusive diagnostics, the model predicted temperature, flame height, and major species very well. Peak benzene concentrations and soot volume fraction were predicted to within 20% of the experimental value. The predicted distribution of benzene was excellent, but the soot was underpredicted along the centerline. This deficit was attributed to limitations in the PAH growth model. Oxidation of particulates was dominated by reactions with hydroxyl radical at superequilibrium levels. Radiation losses significantly effected predicted temperatures.

Download or read book Correlation of Soot Formation in Turbojet Engines and in Laboratory Flames written by Robert K. Gould and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data obtained from aviation gas turbine combustor tests have been examined to determine the effects of fuel properties on soot-related measurements such as engine smoke number, combustor flame radiation, and/or combustor linear temperature. Some tests of smaller laboratory combustors used to simulate these large combustors were also examined. From the existing data it is clear that soot production is a strong function of the fuel chemical composition. Variations in the physical properties of the fuel do not correlate well with soot-related effects. In studies in which a broad range of fuel properties was examined, correlation of soot-related effects with basic fuel compositional parameters including (1) the hydrogen content of the fuel, (2) the aromatic content of the fuel, and (3) the amount of multiple-ring aromatics in the fuel show that typically only the first of these correlates well. However, it has also been shown that fuel compositions can be chosen for which this correlating parameter fails.

This book was released on 2018-08-14 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of fuel type, inlet air pressure, inlet air temperature, and fuel/air ratio on the combustor radiation were investigated. Combustor liner radiant heat flux measurements were made in the spectral region between 0.14 and 6.5 microns at three locations in a modified commercial aviation can combustor. Two fuels, Jet A and a heavier distillate research fuel called ERBS were used. The use of ERBS fuel as opposed to Jet A under similar operating conditions resulted in increased radiation to the combustor liner and hence increased backside liner temperature. This increased radiation resulted in liner temperature increases always less than 73 C. The increased radiation is shown by way of calculations to be the result of increased soot concentrations in the combustor. The increased liner temperatures indicated can substantially affect engine maintenance costs by reducing combustor liner life up to 1/3 because of the rapid decay in liner material properties when operated beyond their design conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of premixing the reaction air and fuel of a gas turbine combustor on soot formation were investigated. Other parameters such as pressure, temperature and reaction zone fuel-air ratio were also evaluated. Soot formation was found to be dominated by fuel-air premixing and could be suppressed readily through a partial premix process. (Author).
