A burner control system for improving burner performance and efficiency may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.

Burner control system

A system for controlling activity in a combustion chamber. The system does not necessarily need to be mechanically adjusted and yet may provide precise control of a fuel air mixture ratio. A sensing module of the system may have a mass flow sensor that relates to air flow and another sensor that relates to fuel flow. Neither sensor may need contact with fuel. Fuel and air to the system may be controlled. Pressure of the fuel and/or air may be regulated. The sensors may provide signals to a processor to indicate a state of the fuel and air in the system. The processor, with reliance on a programmed curve, table or the like, often based on data, in a storage memory, may regulate the flow or pressure of the fuel and air in a parallel fashion to provide an appropriate fuel-air mixture to the combustion chamber.

System and approach for controlling a combustion chamber

Methods and systems for mitigating condensation in a sensor module of a combustion appliance are disclosed. In one example, a fluid flow from a main conduit is cooled with a passive heat exchanger. A sensor of a sensor module may be heated to a temperature above the cooled fluid flow. Cooling the incoming fluid flow with a passive heat exchanger and/or heating the downstream flow sensor may help mitigate condensation in the sensor module, and in particular, on the sensor device. This may help increase the reliability of the system.

System and methods for mitigating condensation in a sensor module

Methods and systems for controlling a gas valve assembly and/or combustion appliance may include identifying a flow rate of gas to a burner of a combustion appliance and determining if the flow rate is sufficient for a burner load of the combustion appliance. If the flow rate is sufficient for a burner load, a position of the valve member of the valve assembly and/or the burner load may be adjusted such that the flow rate of gas meets a target flow rate of gas for the current burner load. If the flow rate is insufficient to meet the current burner load, the valve member of the valve assembly may be positioned in a fully open position to at least partially meet the current burner load. If the flow rate is below a minimum flow rate threshold, the valve member may be moved to a fully closed position.
