Lessons learned from transient analysis of combustion equipment in the process industries | During gas flare operation, hydrocarbon gas is fed through a flare stack and ignited by a pilot. During the ignition process, flares generally produce significant amounts of smoke (see Figure 1) since enough mixing energy is not available to entrain surrounding air to completely burn the flare gas. ... | ||

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... | |

Explaining the "three inch rule": why model flares don't match full-scale | 2022 | It was Pohl and co-workers who discovered the so-called "Three Inch Rule" in their work on flares in the 1980s. They found that model flares with pipe diameter less than three inches do not have the same Combustion Efficiency (CE) and stability behaviour as full-scale flares, at least when wind is n... | |

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... |

Simulation of the thermal-acoustic coupling inside an industrial hazardous waste incinerator | To analyze the coupling between combustion reactions and the natural acoustic behavior of a reactor, a transient LES based CFD code has been used. Previous transient analysis of ignition inside large process heaters, of multi-tipped elevated gas flares and waste incinerators has shown the ability of... | ||

Coanda effect enhanced air assisted flare for low flow operation: cold flow CFD analysis | This paper aims at increasing the flow velocity in the flare stack by decreasing the flow diameter to solve the issue of low flow operation in the flares. A new air assisted flare design of 1m height and 15cm diameter has been tested using CFD simulation in this work. The design includes injecting a... | ||
