Abstract

A power burner system for use with a heating appliance includes a burner tube, a gas valve for providing gas to the burner tube, and a variable speed combustion air blower for mixing air with the gas provided to the burner tube. The burner system further includes a control in communication with the gas valve and the combustion air blower. In one embodiment, the burner system may be used in a conveyor oven. In another embodiment, a conveyor oven includes air circulating fingers having at least first and second air discharge apertures with different flow areas for providing heated air to a cooking chamber of the oven. In another embodiment, a conveyor oven includes apertures through a wall separating the cooking chamber from a blower compartment. The apertures define different flow areas such that the flow rates through the apertures differ.
