78 Kretzschmar, SimonEnviromix_split_phase_applying_flameless_combustion_principles_to_pyrolysis_furnaces2011As the drive towards reduced NOx emissions accelerates, the need to promote synergy between all furnace components becomes paramount. One of the most exciting methods of reducing these emissions is through the application of the principles of flameless combustion. Through high rates of flue gas reci...
79 Gogolek, Peter E.G.; Hayden, A.C.S.Efficiency of flare flames in turbulent crosswind2010Flares are used for the safe, clean and economical disposal of waste gases, whether in upstream oil production (solution gas flares), refineries, gas plants or other chemical processing facilities. Elevated flares are exposed to all the weather patterns, perhaps the most important is the crosswind. ...

81 Thekdi, Arvind C.Energy conservation and pollution control (Abstract)The paper discusses the effects of pollution control, particularly NO control, methods, on heat demands for the process. The effects of combustion modification methods, such as stoichiometric combustion, flue gas recirculation and steam or water injection are studied in a laboratory furnace and the ...
82 Shelil, Nasser; Bagdanavicius, Audrius; Griffiths, Anthony; Syred, NickFlashback analysis for hydrogen/methane mixtures for premixed swirl combustion2009The flashback problem which occurs by using lean premixed combustion in gas turbines is considered. Flashback simulation studies using CFD modelling package are performed for a wide range of hydrogen/methane (H2/CH4) blends combusted by air using a swirl burner under premixed conditions. The laminar...
83 Panfili, R.; Dothe, H.; Vujkovic-Cvijin, P.; Tan, X.; Kennett, R.; Taylor, R.; Bernstein, L.; Smith, Philip J.; Thornock, J.N.; Gross, K.; Seebold, J. G.High fidelity modeling of flare combustion and emission detection2011-08-17The combustion of hydrocarbons by industrial flares emits greenhouse gases into the atmosphere along with trace amounts of ozone-forming highly-reactive volatile organic compounds and human carcinogens. Continuous and autonomous monitoring of flare emission is challenging due to low species concentr...
84 Pohl, John; Gogolek, Peter E.G.; Seebold, James G.; Schwartz, RobertFuel composition effect on flare flame inefficiency2004The effects of fuel composition on the performance of flare flames have long been known. Possibly the first performance indicator was the tendency of a fuel to smoke. Various fuel characteristics such as average molecular weight and carbon-to-hydrogen ratio were advanced to guide the design of early...

86 Muhasilovic, M.; Duhovnik, J.; Deville, M. O.; Ciahotny, K.; Koza, V.Both LES and k-e turbulence-treatment in CFD-approaches for creation of the database on flare-stacks flame-behaviour2009There 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...
87 Henneke, Mike; Matos, MiguelCFD analysis of a ground flare system: wind and fence effects on air supply behavior and thermal radiation2011Thermal radiation emitted from ground flare installations is a safety consideration • The fence material must be selected to tolerate the high heat fluxes • The fence has an influence on air supply to the burners and can cause air circulation patterns within the fenced area
88 Giovanardi, EnricoOpen Ground Flare systems - Hystorical review of a recent project from the concept to the commissioning, passing through R&D activities Presentation and Discussion of the Results of R&D activities as a basis for design and execution stage.2011The more and more restrictive environmental laws and regulation applied in most of the projects all over the world led in the last years to the need to increase on one hand smokeless performances of assisted flares, to guarantee smokeless combustion up to Ringelmann 0, and, on the other hand to inst...
89 Wheeler, W. H.Chemical & engineering aspects of low NOx concentration1980-07-07Two 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...
90 Zeuthen, Jacob Hjerrild; Pedersen, Anne Juul; Riber, Christian; Astrup, Thomas; Hansen, Jorn; Frandsen, Flemming Jappe; Livbjerg, HansCombustion aerosols from municipal waste incineration - effects of feedstock composition and boiler operation2009Combustion aerosols were measured in the 22 MWth FASAN Waste-to-Energy (WtE) boiler while applying changes in feedstock composition and grate operation conditions, respectively. The changes in feedstock composition were applied by adding (one-by-one) dedicated waste fractions, comprising PVC plastic...

95 Smith, Philip J.; Kumar, Seshadri; Spinti, Jennifer; Desam, Padmabhushana R.; Borodai, Stainslav G.An LES analysis of industrial flare performance under high wind conditions2005
96 Acceptable operating parameters for steam assisted flares at Purge RatesFlare 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...
97 Atreya, Arvind; Kezerle, James A.A novel method of waste heat recovery from high temperature furnaces to create radiative flameless combustion2009One 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...
