 | Wheaton, Zachary; Stroh, David; Krishnamoorthy, Gautham; Muhammad, Sami; Orsino, Stefano; Nakod, Pravin | A comparative study of gray and non-gray methods of computing gas absorption coefficients and its effect on the numberical predictions of oxy-fuel combustion | Computational Fluid Dynamics (CFD) simulations are performed to model the radiation process in natural gas fired furnaces using different gray and non-gray radiation models. Simulations of two representative furnace cases (HTAC and OXYFLAM) were performed and the computed radiative fluxes compared w... | |

 | Atreya, Arvind; Kezerle, James A. | A novel method of waste heat recovery from high temperature furnaces to create radiative flameless combustion | 2009 | One of the largest heat losses in high temperature furnaces is the loss of flue gas enthalpy. Currently, up to 60% of the heating value of natural gas (or any other fuel) used in high temperature furnaces is lost via the flue gases. This work discusses the benefits and technology of re-circulating t... |

 | Smith, Philip J. | A technology for measuring combustion efficiency of industrial & field flares (integrating measurements and simulations) | 2011-08-12 | Flare research over the past decade has increasingly illustrated that there is likely no one simple operational parameter (or even a few parameters) that will characterize the combustion behavior of flare flames.i Simple correlations are unobtainable because of the complexity of the nonlinear mixing... |

 | Acceptable operating parameters for steam assisted flares at Purge Rates | Flare vendors recommend that cooling steam should always be supplied to the steam injection equipment on steam assisted flare tips. However, the nomenclature of "cooling steam" properly describes only one aspect of this steam flow. Not only does this steam provide thermal protection to the steam inj... | ||

 | American flame research committee (AFRC) international combustion symposium | 2011 | Burner retrofits in industrial boilers are an economical solution to achieving lower NOx levels with existing fired equipment. However, designing a next generation ultra-low NOx burner footprint that fits into an existing burner cutout continues to be an industry challenge in many applications. Buil... | |

 | Hu, Shengteng; Zeng, Dong; Sarv, Hamid | Applying laser-induced incandescence (LII) technique to soot volume fraction measurements for pyrolyzing pulverized coal | 2009 | Staged combustion and gasification of coal are conducive to soot formation. Presence of soot in combustion systems can affect heat transfer, pollutant formation, and unburned carbon levels.Development of an accurate soot production model requires high-quality experimental data. For this purpose, the... |

O.; Ciahotny, K.; Koza, V. | Both LES and k-e turbulence-treatment in CFD-approaches for creation of the database on flare-stacks flame-behaviour | 2009 | There is an emerging importance to understand and to "map" the reacting complex-flows of the (larges-cale) flare-fires. In this study, the influence of the atmospheric events onto the flame-behaviour, has a start-up in investigation, by watching the development of the temperature-, velocity- and irr... |

 | Wheeler, W. H. | Chemical & engineering aspects of low NOx concentration | 1980-07-07 | Two new requirements for low NOx emission from industrial combustion installations are explained. One, which is directed against a previously unsuspected and dangerous form of contamination of certain food-stuffs, calls for a NOx concentration not exceeding 1 ppm at the burner mouth; and the other i... |

 | Mueller, Gary R.; Agrawal, Harshit; Caico, Chris; Olivacce, Ronald | Combustion of mixtures: A modified IFC approach | 2011 | While most studies on flares have been done with single hydrocarbon fuels or binary mixtures, the reality of most industrial flares is that they see different mixtures of many gases. Over the past 5 years the International Flare Consortium (IFC) has been conducting research on just this issue. In a ... |
