ABSTRACT:
A gas convection oven having a radiant burner and fuel feeding apparatus which enables the single burner to be operated in either a broil mode or a bake mode. In the broil mode, the radiant burner is operated in conventional manner with the flame being held by an inner screen to heat the outer screen to a radiant luminous temperature. In the bake mode, forced air is injected into the burner by a fan thereby providing a leaner fuel-air mixture with higher velocity. As a result, the flame burns outside the outer screen of the burner with the outer screen serving as a flame holder. Therefore, hot combustion gases as produced while the outer screen remains non-luminous.
