Abstract: A combustion efficiency control system includes an air flow sensor arrangement, a fuel controller unit, a burner output sensor module, and an operating unit. The air flow sensor arrangement including an upstream laminar flow control system and a downstream laminar flow control system and is communicatively coupled to a damper, a blower, and a flow conditioner. The air flow sensor arrangement measures laminar air flow and emits an efficiency signal that includes laminar air flow input values. An operating unit compares laminar air flow input values with combustion output values and a stoichiometric controller receives the comparison to generate an efficiency signal having a combination of air and fuel control data for the damper, the blower, the flow conditioner and the fuel controller unit, respectively. The stoichiometric controller maintains a selected combustion efficiency setting until cancelled.
