A micro gas burner () is provided that generates a stable, pre-mixed flame that produces little to not soot or unburned hydrocarbons. The gas burner includes a fuel inlet, a nozzle (30), an oxygenation chamber (40) with at least one air inlet (45), a mixing chamber (50) having a frustoconical inner wall,, at least one permeable barrier (60) and a flame holder (70). The gas burner throughly mixes fuel and entrained air to form a nearly stoichiometric mixture prior to combustion. The gas burner mixes the fuel and air so throughly that it requires a lower fuel flow rate than would otherwise be necessary to produce a stable, pre-mixed flame. The gas burner may include an optional flame tube with an optional exhaust port in which a flame is contained and sequestered from diffusing air.
