Miscellaneous Applications of Coanda Effect
Published in Noor A. Ahmed, Coanda Effect, 2019
A gas flare, also known as a flare stack, is used in the combustion of flammable gas in industrial chemical and gas processing plants, and oil refineries. The flaring is intended to protect against over-pressuring industrial plant equipment from catastrophic incidents. A flare is also used at oil or gas production sites that have oil wells, gas wells, and so forth for wastes or unusable gas.

The combustion behaviour of the gas flare can be controlled and the incineration process can be optimized by controlling the combustion temperature and CO emission and, eventually, by adjusting the combustion air stream. Combustion in gas flares is usually carried out with λ = 1.6-1.8. This results in an oxygen content in the exhaust gas of about 8-9 vol.% O2.

Gas flare systems (Baukal 2012) are structures used to collect and burn the disposable gases from different stages of the process plant. The combustion of these disposable gases is performed in a safe manner far from the plant. A typical flare system is shown in Figure 7. The flare stack collects the flare gases that are to be flared. To improve combustion efficiency, the flare tip is designed to allow the entrance of air into the flare. To prevent the flashback of the flare, seals are installed in the stack. The knock-out drum resides at the base of the stack, which operates at a relatively low pressure (Zadakbar, Khan, and Imtiaz 2015). The knock-out drum should be able to prevent liquid carryover into the flare while the flare operates with large gas and liquid loads (Akeredolu and Sonibare 2004).
