Abstract
The gas flare system includes a vertical flare stack having an opened top end and a bottom floor wall. A weatherproof protective hood arrangement prevents rain and snow from entering through the opened top end. The gas flare system also includes a burner arrangement provided through the bottom floor wall. The burner arrangement receives a waste gas stream from a waste gas circuit and also primary air. Secondary air orifices around the burner supply secondary air coming from a plenum housing located directly underneath the bottom floor wall. The gas flare system can destroy the flammable gas in the waste gas stream with a combustion efficiency of more than 99% under almost any operating conditions. It can start automatically and operate efficiently without any supervision under any possible atmospheric conditions. A method of destroying a flammable gas in a waste gas stream is also disclosed.
