A bayesian decision-theory-based digital twin for methane flares | 2022 | Ground flares operate in a high-turndown, standby configuration for a significant portion of their operating life, being fully utilized only under process upset scenarios or emergencies. The low-momentum flow results in poor fuel-air mixing near the flare tip, leading to decreased overall combustion... | |

Analysis of burner operation inside an enclosed ground flare | 2022 | Thermo-Acoustic Coupling; Enclosed Flare; LES CFD Model; Noise; Premixed Burner | An industrial enclosed ground flare used as part of a large refinery project has been analyzed to assess combustion stability and performance under low and high flow conditions. This flare includes a large combustion chamber directly above the burner deck with Low Flow (LF) burners that fire up to 9... |

Capturing the effect of near-and far-field dynamics on the combustion efficiency of multi-point ground flares | 2022 | Multi-point ground flares are frequently used in scenarios where flare gas flow rates can be high and pollution (noise, light, smoke) needs to be minimized. We have applied Arches, a large eddy simulation (LES) tool that we have developed for capturing the dynamics of flares (turbulent mixing, local... | |

Analysis of design and operation of multi-point ground flares | 2022 | Multi-point ground flares (MPGF) are used to process large quantities of hydrocarbon gases generated in chemical processing or petrochemical refining. These flares use hundreds of flare burners arranged and fired in a staged fashion. A wind fence surrounds the MPGF to shield the flames from plant op... | |

Investigative approach to address thermoacoustic vibration in gas-fired heaters and boilers | 2022 | Industrial gas-fired boilers, furnaces and heaters occasionally encounter low-frequency vibrations generated by dynamic feedback between the burner (or burners) and acoustic modes in adjacent cavities in the main combustion chamber or ductwork. Feedback occurs when pressure pulses associated with ac... |
