Abstract:
1. A power burner system for use with a heating appliance, the burner system comprising: a burner tube; a gas valve adapted to receive gas from a supply and to provide gas to said burner tube, said gas valve adjustable to a plurality of positions to provide gas at a controlled rate; a variable speed combustion air blower operatively coupled to said burner tube and adapted to mix air with the gas from the supply; a control communicating with said gas valve and said combustion air blower, said control operative to modulate said gas valve and said combustion air blower to control gas flow from said gas valve and air flow from said blower to maintain substantially stoichiometric conditions of the air and gas flow into said burner tube; and a sensor configured to directly measure a rotational speed of said combustion air blower and to send signals to said control related to the measured rotational speed; wherein said modulation of said combustion air blower is related to the measured rotational speed.
