An intelligent cooktop has at least a first, if not multiple burners in proximity to at least a first sensor, respectively, wherein the first sensor provides an input to a processor which evaluates a burner performance characteristic selected from the group of least one of flame level, temperature rise, time lag, and temperature level using the first sensor compared to an anticipated performance characteristic of the first burner based on the valve position; and then provides a burner performance output to a user identifying a condition of the first burner.

Flame monitoring device (23) for a gas burner appliance (10), the gas burner appliance (10) being configured to burn a combustible gas, the combustion of the combustible gas resulting into a flame (12), comprising a flame supervision device (24) providing as measurement signal an electrical voltage signal depending on the presence of the flame (12), and an electronic circuit (25) converting the electrical voltage signal provided by the flame supervision device (24) into an electrical current signal.

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.

In an embodiment, a method of controlling flaring of a combustion gas including a flare gas, a supplemental fuel gas, and an assist gas is provided. Models estimating, based on flow rates and in-situ speed of sound measurements in the gases, net heating value of the combustion gas within a flare combustion zone, combustion efficiency of the combustion gas, and smoke yield of the combustion gas are maintained. The method also includes receiving measurements of the gas flow rates and determining set points for flow rates of the fuel gas and/or the assist gas based upon the models that achieve a target combustion efficiency. When a difference between a determined set point and its corresponding flow rate for the fuel gas and/or the assist gas is greater than a corresponding predetermined tolerance amount, that flow rate can be adjusted to reduce the determined difference below the predetermined tolerance amount.

Methods and apparatus to indicate presence of a flame are disclosed. An example gas grill includes a burner tube having apertures to emit a fuel for combustion, an ignition element to cause ignition of the fuel emitted from the apertures of the burner tube, a flame sensor to detect the presence of a flame associated with the combustion of the fuel emitted from the apertures of the burner tube, and flame sense circuitry including a flame signal accessor to access a flame sense signal from the flame sensor, and a terminal to output an indication of the presence of the flame, the indication of the presence of the flame output without respect to an open or closed state of a lid of the grill.

A system for a gas turbine engine includes an igniter event conductor. The igniter event conductor has a first portion adjacent an igniter of the engine and in a combustion chamber of the engine and a second portion apart from the igniter and apart from the combustion chamber. The conductor is adapted to conduct an aspect of an igniter event at the igniter from the first portion to the second portion. A sensor is coupled to the second portion of the conductor to sense the aspect of the igniter event.

An apparatus may comprise a first carrier tube having a first input end and a first output end and a second carrier tube disposed substantially parallel to the first carrier tube and having a second input end and a second output end. A cross tube may be coupled to the first carrier tube and the second carrier tube and may be disposed substantially perpendicularly between the carrier tubes. A plurality of burner holes may be disposed along the first carrier tube, the second carrier tube, and the cross tube. A plurality of flame sensors may be disposed at various locations of the first carrier tube and the second carrier tube. A first igniter assembly may further be coupled to the first carrier tube.

A system and method in which (i) a flame scanner provides UV and/or IR wave period and amplitude information for a burner flame and (ii) a flame stabilization metering module determines whether the wave period and amplitude of the flame have reached warning and shutoff set points for the burner, thus indicating that the operation of the burner is unstable, or that a flame out event is likely, and, in which event, corrective actions are taken, or the burner is shut down, to restore stable operation and prevent a flame out from occurring.

A method for controlling a fuel-oxidizer mixture in a premix gas burner includes: receiving a flame signal representing the presence of a flame deriving from the combustion of a fuel of a first predetermined type or a second predetermined type inside a combustion cell; accessing fuel data representing the fact that the gas fuel belongs to the first type or the second type; generating drive signals to control a gas flow regulating valve that supplies gas to the burner and to control a rotation speed of a fan configured to take in oxidative air; sending the drive signals to the gas flow regulating valve and to a motor connected to the fan. A memory unit contains first regulation data and second regulation data and is programmed to generate the drive signals based on the first regulation data or on the second regulation data, depending on the fuel data.
