A method for a combustion system includes outputting fuel from an adjustable-position fuel nozzle onto a perforated flame holder, the fuel being directed for mixture with an oxidant en route to the perforated flame holder. A combustion reaction of the fuel and the oxidant is supported within the perforated flame holder. A position of the adjustable-position fuel nozzle may be changed relative to the flame holder. A first flow of fuel may be output when the adjustable position fuel nozzle is in an extended state, and a second flow of fuel may be output when the adjustable-position fuel nozzle is in a retracted state.

The controller is configured to initiate a calibration process to determine an active range for the gas cooking element.

A regulation device for regulating a mixing ratio (x) of a gas mixture comprises a first conduit (1) for carrying a flow of a first gas (e.g., air) and a second conduit (2) for carrying a flow of a second gas (e.g., a fuel gas). The first and second conduits (1, 2) open out into a common conduit (3) in a mixing region (M) to form the gas mixture. A first sensor (S1) is configured to determine at least one thermal parameter of the gas mixture downstream from the mixing region. A control device (10) is configured to receive, from the first sensor, sensor signals indicative of the at least one thermal parameter of the gas mixture and to derive control signals for adjusting device (V1) acting to adjust the mixing ratio, based on the at least one thermal parameter.

A high temperature carbon monoxide sensor for in-situ combustion monitoring is provided having a yttrium-stabilized zirconia interface based emf-measuring electrochemical sensor and a nickel oxide (NiO) first sensing electrode for targeting carbon monoxide gas at a temperature range from between about 1000 degrees Centigrade to about 1200 degrees Centigrade. A method of measuring carbon monoxide using this sensor is provided.

A gas fired burner control system for a kiln for firing for instance ceramic items. The system including a plurality of operating modes, with the system being configured such that during a firing cycle the system can move between operating in different modes.

A water heater control system comprising an energy storage system electrically connected to a pilot valve operator and electrically isolated from a main valve operator. The energy storage system may be electrically connected to an ignition circuit. A thermoelectric device is in thermal communication with the pilot flame and electrically connected to a main valve operator. The water heater system may include a microcontroller configured to establish electrical communications between the device and the energy storage system, the pilot valve operator, and the main valve operator. The microcontroller may be configured to recognize a call for main burner operation, and may also be configured to check an available voltage of the energy storage system against a setpoint. The microcontroller may establish pilot flame operation with or without main burner operation, depending on whether a call for heat or recharging of the energy storage system is required.

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 water heater may include a water tank, a burner, a pilot for igniting the burner, an ignitor for igniting the pilot, a thermoelectric device in thermal communication with a flame of the pilot, a controller for controlling an ignition sequence of the pilot using the ignitor, and a rechargeable power storage device for supplying power to the ignitor and the controller. The rechargeable power storage device may be rechargeable using the energy produced by the thermoelectric device. The controller is configured to selectively ran only the pilot for at least pan of a heating cycle to increase the recharge lime of the rechargeable power storage device while still healing the water in the water heater.
