Abstract

Systems and methods for purging air and/or one or more inert gases from a flammable gas system, such as a natural gas pipeline, are described. In particular, this application discusses systems and methods for making and using a gas purge burner to purge air/inert gases from a flammable gas system. The gas purge burner includes a burner having a gas inlet and a gas escape vent. The burner also has a continuous ignition mechanism that includes an igniter (such as a pilot light and/or an electric igniter) that is disposed near the gas escape valve. The burner also has a gas outlet that can be disposed between the gas inlet and the gas escape vent and which is also configured to direct gases from the burner to a gas measurement device. The burner can be used to monitor the amount of flammable gas flowing into the burner and to continually ignite and burn off such gas until the stream of gas passing through the burner is substantially pure. Thus, the gas burner can allow a user to perform such tasks while being removed a safe distance from the actual burner, increasing the safety of the user during the pursing process. Other implementations are described.
