Ron, Yes it will ignite. The friction created by the air immediately around the glas flow will slow the gas enough to allow conditions for ignition. On the large scale the gas is burning but on the smaller scale the burning will only take place in an area where the ratio of the air/gas mixture falls between the upper and lower explosive limits. For natural gas this is between about 5% and 16% natural gas in air. Hydrogen sulfide is 4 to 44%. Carbon dioxide does not burn. Completion of combustion will vary on too many factors to determine the overall rate. These factors include debris in the flow, manner of venting, wind velocity, water content of the gas stream etc.
