A flame analytics system that may incorporate a burner, one or more sensors at the burner, a historical database connected to the one or more sensors, a model training module connected to the historical database, and a runtime algorithm module connected to the one or more sensors and the model training module. The runtime algorithm may compare realtime data from the one or more sensors and historical data from the model training module in accordance with a machine learning algorithm. The system may further incorporate a fault detection module connected to the runtime algorithm module, a fault diagnostics module connected to the fault detection module, and an enunciator connected to the fault detection module. The one or more sensors may also include having video or acoustic sensitivity of combustion in the burner.

Flame analytics system

A pressure sensor apparatus and a method of operating the pressure sensor apparatus can include a hybrid pressure switch having a single switching point, the hybrid pressure switch comprising: a mechanical pressure switch; and an electronic pressure sensor, wherein the hybrid pressure switch monitors a media pressure with the mechanical pressure switch providing a switching function and the electronic pressure sensor providing a continuous pressure measurement with respect to the media pressure based on a continuous pressure output signal. The switching function can comprise a fail-safe switching function or a non-fail-safe switching function.

Pressure monitoring using a hybrid pressure switch

An electronic device and a method are disclosed. The electronic device includes a sensor, a memory, a processor, and a communication interface. The sensor is configured to detected vibrations of a burner system including any component of a burner system. The memory is configured to store the detected vibrations. The processor is configured to record the detected vibrations caused by the burner system at a predetermined time interval. The processor is also configured to generate a report of the recorded vibrations caused by a burner component to indicate the operational status of the burner, wherein the generated report includes at least two recorded vibrations. The communication interface configured to transmit the generated report.

Burner health monitoring using vibration sensing

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

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a gas valve assembly may include a valve body with one or more valves movable between an opened position and a closed position, one or more valve actuators configured to operate the valves, and one or more pressure sensors to sense a pressure within a fluid path of the valve assembly. A valve controller may receive a measure related to a sensed pressure from the one or more pressure sensor(s). The valve controller may compare the received measure related to the sensed pressure to an overpressure threshold. In the event the measure related to the sensed pressure surpasses the overpressure threshold value, the valve controller may be configured to provide a signal that indicates an overpressure event has occurred.

Gas valve with overpressure diagnostics

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, the valve assembly may include a valve body with an inlet port, an outlet port, and a fluid path extending between the inlet and outlet ports, one or more valves situated about the fluid path, one or more valve actuators for selectively moving respective valves, one or more sensors for sensing one or more parameters within the fluid path, and a controller secured relative to the valve body and in communication with the one or more sensors for determining one or more valve assembly conditions based on the one or more sensed parameters. Illustratively, the controller may be configured to communicate information from the valve assembly to a combustion appliance controller that is located remotely from the valve assembly through a communications interface of the controller and across a communications bus.

Gas valve with communication link

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

The disclosure relates generally to pressure regulators, and more particularly, to pressure regulating valves. In one illustrative but non-limiting example, a pressure in a flow channel is translated into a position of a diaphragm, wherein the position of the diaphragm is dependent on the pressure in the flow channel. The position of the diaphragm is then sensed. A position of a valve in the flow channel is then controlled to adjust the pressure in the flow channel acting on the diaphragm so that the sensed position of the diaphragm is driven toward a predetermined position. This may result in regulated pressure in the fluid channel.

Pressure regulator

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 low powered system for providing sufficient current to a fuel control mechanism drive. The system may have a fuel control mechanism pick circuit that has an energy storage mechanism for providing a large amount of current for a short time to the fuel control mechanism drive. A safety switch may be enabled with a special signal to let current flow to the fuel control mechanism drive to operate a corresponding fuel control mechanism for controlling fuel to a pilot light or heating element. The pilot light or heating element may provide heat to a thermoelectric source that generates electrical power from the heat. The electrical power may go to a single DC-to-DC converter and voltage clamp for providing a voltage source to a microcontroller and other circuits of the system. The pick circuit may prevent a harmful reverse flow of current from the storage mechanism to the thermoelectric source.

Low-powered system for driving a fuel control mechanism

One system includes a single calorimeter or a single gas chromatograph configured to determine a calorific value of a gas being supplied to an area having a plurality of appliances and communicate the calorific value of the gas to the plurality of appliances.

Providing appliances with gas quality information

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body, a valve situated in a fluid path of the valve body, a valve actuator for selectively moving the valve actuator, one or more sensors in communication with the fluid path, a controller secured relative to the valve body and in communication with the sensors, and memory operatively coupled to the controller. A user interface may be in communication with the memory and the controller and may be configured to receive a selection from a user for selecting one of two or more selectable options from the memory. The controller may compare sensed parameters to threshold values associated with the selected option. The user interface may have a lock on it to prevent tampering and to provide accountability.

Methods, systems, and computer-readable media are described herein. One method embodiment includes determining an unscaled efficiency signal of combustion equipment using data measured from the combustion equipment, determining a theoretical efficiency signal of the combustion equipment using a theoretical efficiency surface of the combustion equipment and a subset of the measured data, and normalizing the unscaled efficiency signal using values from a correlated portion of the theoretical efficiency signal to monitor efficiency of the combustion equipment. Other embodiments can include providing a performance indicator of the combustion equipment in response to an operational mode change.
