API Std 537:2003 pdf download.Flare Details for General Refinery and Petrochemical Service.
3.23 elevated flare: A flare where the burmer is raised high above ground level. It is elevated to reduce radiation intensity and to aid in dispersion.
3.24 excess air: Air provided to a flame in excess of stoichiometric requirements.
3.25 flame detection system: A system that verifies a Hlame is present.
3.26 flame front generator: A means of lighting the pilot. A combustible gas air mixture is created and allowed to fill an ignition line connecting the flame front generator and the pilot. lgniting the mixture allows the flame front to travel through the ignition line to the pilot.
3.27 flame monitor: See flame detection system
3.28 flame retention device: A means to prevent flame blowoff from a lare burner.
3.29 flame velocity: See burming velocity
3.30 flare: A general term used to designate a device or system used to safely dispose of relief gascs in an environmentally compliant manner through the use of combustion.
3.31 flare burner. The part of the flare where fucl and air are mixed at veloeities, turbulence and concentration required to cstablish and maintain proper ignition and stable combustion. It is also referred to as the flare tip.
3.32 flare header: The piping system that collects and delivers the relief gases to the fare.
3.33 flare tip: See flare burmer
3.34 flashback: The phenomenon that occurs in a fammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the fame velocity, causing the flame to travel back to the point of mixture.
3.35 ground flare: Any non- clevated flare. It is normally an enclosed flare but may also refer to a ground multi- bumer flare or a burmpit.
3.36 guyed flare: An elevated flare with the riser supported with cables.
3.37 heat release: The total heat liberated by combustion of the relief gases based on the lower heating value. expressed in kilowalts ( British thermal units per hour).
3.38 heating value, higher (HHV): The total heat obtained from the combustion of a specified fuel at 16°C (00^F),expressed in kilojoules per kilogram or per cubic meter (British thermal units per pound or per cubic f). It includes the latent heat of vaporization of the water formed
by the combustion of hydrogen in the fuel The Higher heating value is synonymous with the gross heating value.
