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... |

Chambers, Allan K.; Wootton, Tony; Moncrieff, Jan; McCready, Philip | Combustion efficiency of full scale flares measured using DIAL technology | 2004 | Flares 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 ... |

Gogolek, Peter E.G.; Hayden, A.C.S. | Efficiency of flare flames in turbulent crosswind | 2010 | Flares 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. ... |

Hantsck, Carl-Christian; Schorer, Edwin | Flares - noise prediction and thermo-acoustic efficiency | 2004 | In 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... |

Pohl, John; Gogolek, Peter E.G.; Seebold, James G.; Schwartz, Robert | Fuel composition effect on flare flame inefficiency | 2004 | The 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... |

G. | High fidelity modeling of flare combustion and emission detection | 2011-08-17 | The 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... |

Diez, Francisco J.; Dahm, Werner J.A. | Improved prediction of buoyancy effects on flame length and combustion properties of flares | 2004 | An 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... |

Shore, David | Improving flare design a transition from art-form to engineering science | 2007 | Many 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... |
