1 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...

5 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...
6 Chambers, Allan K.; Wootton, Tony; Moncrieff, Jan; McCready, PhilipCombustion efficiency of full scale flares measured using DIAL technology2004Flares are used in Alberta's oil and gas industry to safely treat H2S containing gas releases during emergencies, and gas well flow tests and as a means of disposing of gases that cannot be recovered economically. Despite the wide use of these flares, little data exists on the combustion efficiency ...
7 Martin, MatthewComparison of empirically based calculation methods for pipe flares to computational fluid dynamics2007As available computational resources increase and the use of computational fluid dynamics (CFD) becomes more widely accepted wider classes of industrial scale combustion systems are being simulated and optimized using these resources. A largebody of empirically based work has already been assembled ...
8 Duck, BrianComputational fluid dynamic modeling of a ground flare2007A major ethylene plant underconstruction in Al-Jubail, Saudi Arabia found itself under pressure from neighboring facilities and regulatory agencies to reduce flare emissions, flame visibility, and noise. Plant personnel contacted a company that had pioneered and commercialized a grade mounted, multi...
9 Desam, Padmabhushana R.; Smith, Philip J.; Borodai, Stainslav G.; Kumar, SeshadriComputing flare dynamics using large eddy simulations2004Computing the dynamics of flares is motivated by the increased need for efficient and safe flaring of unwanted gases during hydrocarbon and petrochemical processing. To understand the unsteady flame shape dynamics, Large Eddy Simulations (LES) are used to study natural gas flares in the presence of ...
10 Zhan, Z.Effects of Coal Blends on Formation Mechanisms of Ash Aerosol and Ash Deposits during Air and Oxy-Combustion2015-09-11Paper from the AFRC 2015 conference titled Effects of Coal Blends on Formation Mechanisms of Ash Aerosol and Ash Deposits during Air and Oxy-Combustion
11 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. ...

13 Smith, Joseph D.; Suo-Anttila, Ahti; Smith, Scot K.; Modi, Jay B.Evaluation of the air-demand, flame height, and radiation from low-profile flare tips using ISIS-3D2007Low-profile flare fields pose significant design challenges including elongated flames, adequate air supply to burner tips located on inner rows and high radiation flux from the flame to the surrounding wind fence. Recent work completed by engineers at Alion Science and Technology for Zeeco, Inc. ha...

15 Hantsck, Carl-Christian; Schorer, EdwinFlares - noise prediction and thermo-acoustic efficiency2004In many industries where combustible waste gases are obtained, flares are used to burn these gases in a controlled manner. Among other environmental aspects the noise emissions associated with flaring are becoming increasingly important in many countries as population density goes up and residential...
16 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...
17 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...
18 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...
19 Diez, Francisco J.; Dahm, Werner J.A.Improved prediction of buoyancy effects on flame length and combustion properties of flares2004An improved integral method is presented for determining the flame length and combustion properties of buoyant jet flames, including flares, that avoids the Morton entrainment hypothesis entirely and thereby removes the ad hoc "entrainment modeling" required in most other integral approaches. Rather...
20 Shore, DavidImproving flare design a transition from art-form to engineering science2007Many of the day-to-day activities surrounding Flaring, at both the project design and operational stages, are vague and apparently outside the control of the Flare Engineer. Design specifications usually only cover a single case out of a multitude of possible compositions and flows. In service, flow...
21 Hong, J.; Baukal, C.; Bastianen, M.; Bellovich, J.; Leary, K.Innovative steam-assisted flare technology2007A new steam-assisted flare has been developed which reduces or eliminates some of the potential limitations of conventional steam-assisted flares. The improved performance includes significantly reduced steam requirements (>30% reduction), elimination of two of the three steam supply lines, simplifi...
