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.

Systems and methods for valve and/or combustion applicance control

A method for determining an change in an operating condition of a gas burner appliance. In some instances, a calibration of a gas/air mixture may be performed when the combustion quality of the gas burner appliance diminishes. This may be accomplished by adjusting a throttle position of a throttle valve that throttles the gas to the gas burner appliance. After calibration has been performed, a throttle position of the throttle valve is determined, and based on the throttle position determined after calibration, a change of an operating condition of the gas burner appliance is detectable.

Method for operating a gas burner appliance

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

A method for commissioning a gas valve assembly for controlling fuel flow to a combustion appliance. An example method for commissioning the gas valve assembly may include initiating a commissioning mode in the controller of the gas valve assembly. Once in the commissioning mode, inputting a user defined initial air to fuel (A/F) ratio, activating the combustion appliance, setting a burner load of the combustion appliance to a set burner load, inputting a desired A/F ratio for the set burner load, running the combustion appliance at the burner load with the desired A/F ratio, and observing the operation of the combustion appliance. The method may further include saving the desired A/F ratio for the set burner load to the controller of the gas valve assembly and exiting the commissioning mode.

Air/fuel commissioning of a combustion appliance

An improved air/gas admittance device for a combustion appliance. The improved air/gas admittance device is configured to provide a more uniform gas and/or air flow. This may help reduce noise in pressure and/or flow sensor measurements that are used by a gas valve controller to control the air/fuel ratio to the combustion appliance, which may help improve the efficiency and/or emissions of the combustion appliance.

Air/gas admittance device for a combustion appliance

In a modulating gas burner, the mixing ratio of a gas/air mixture is controlled over a modulation range of the gas burner by a pneumatic controller. During burner on phases, the combustion quality is monitored via a combustion quality sensor. The combustion quality is used to detect tolerances of the pneumatic controller and/or a potentially changing behavior of the pneumatic controller by checking if the combustion quality is inside or outside a defined combustion quality range. When the combustion quality is inside the defined combustion quality range, the mixing ratio of gas and air of the gas/air mixture is not changed. When the combustion quality is outside the defined combustion quality range, the mixing ratio of gas and air of the gas/air mixture is changed by adjusting a gas throttle to compensate for tolerances of the pneumatic controller and/or for a potentially changing behavior of the pneumatic controller.

Method for operating a gas burner

A solenoid valve in which an actuator is located above a valve seat and closure member. A valve stem which carries the closure member has a particle diverting collar thereon located above a valve stem guide in the valve housing. The valve housing has an annular, upwardly opening well therein encircling the valve stem below the collar, the well functioning as a particle collector.
