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. The control may also be in communication with various other devices of an appliance, such as a variable speed air-circulating fan, a variable speed exhaust fan, or various sensors associated with the heating appliance. The control modulates the gas valve and the combustion air blower to maintain substantially stoichiometric conditions of the gas and air provided to the burner tube and as a function of signals from at least one of the devices. In one embodiment, the burner system may be used in a conveyor oven.
