Igniter for a gas discharge pipe

摘要

An igniter for gas discharge pipes such as flare lines produces a remotely controlled flame. The igniter has a tubular housing that is mounted to the gas discharge pipe. A fuel line extends through the housing and terminates in a nozzle. A swirling device creates a swirling motion in the nozzle to prevent extinguishment due to high winds. An electrical system creates an electrical spark in the nozzle to ignite the fuel. An auxiliary line provides fuel unmixed with air to the nozzle to enrichen the mixture and provide coloration to the flame. The nozzle extends laterally from the housing. The mounting means allows the nozzle to discharge the flame across the face of the discharge pipe. A heat shield protects the upstream end of the housing from heat due to the discharge pipe.
