Abstract
A surface heater automatically adjusts the supply of fuel and/air to the burner in order to maintain a desired air/fuel ratio despite changes in ambient air temperature and/or pressure. The adjustment may be performed on a periodic or continuous basis and on either an open-loop basis or a closed-loop basis. The adjustment includes actuating one or more control devices that control the flow of air and/or fuel to the burner. If the adjustment is performed on a closed-loop basis, signals from a sensor can be used as feedback to control the flow of air and/or fuel into the burner to maintain a setpoint of a controlled parameter. The controlled parameter may include one or more of air mass flow rate, an intake Oconcentration, an exhaust Oconcentration, an exhaust gas composition, and an exhaust gas temperature.
