The flare gas system has a flare gas assembly having an air pipe with an open upper end, a first conduit in surrounding relationship to the air pipe and having a first conduit open upper end, a second conduit in surrounding relationship to the first conduit and having a second conduit upper end, and a third conduit in surrounding relationship to the second conduit and having a third conduit upper end, the upper ends of the air pipe, the first conduit and the second conduit being below the upper end of the third conduit, there being an air source connected to the air pipe to provide air to the air pipe at a desired flow rate. There is at least one second flare gas assembly operatively connected to the first flare gas assembly, the second flare gas assembly having a tubular housing in which is mounted a spring biased orifice plate, the tubular housing being in open communication with the annulus formed below the second and third conduits.
