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.

A method and device heat an object to be heated by a flame which is produced by supplying a fuel fluid and a combustion supporting gas to a burner as a heat, source. A temperature rising rate is increased by gradually increasing an oxygen concentration in the combustion supporting gas supplied to the burner and a device for heating an object to be heated including a burner for heating the object to be heated. A flow rate control unit controls a flow rate of a fuel fluid and a combustion supporting gas.

By calculating the environmental pressure at the burner with the barometric pressure sensor, the controller can adjust blower speed and/or fuel rate to modify combustion efficiency. The barometric-pressure data can also be used to adjust blower speed control bands, thereby calibrating the control bands based on environmental pressure. The environmental pressure can be indicative of altitude and/or weather conditions. Methods of operating said burner appliance are also disclosed.

A first air stream may be tangent to a circular cross-section of the exemplary annular air nozzle, and a first axial inlet that may be configured to allow for axially injecting a second air stream into the annular air nozzle along a centerline of the annular air nozzle.

Systems and methods include a computer-implemented method for providing flare header information. Instantaneous flaring flowrate data is received from flaring sources of a flare network of a processing facility. The instantaneous flaring flowrate data is analyzed in conjunction with physical properties of relief sources obtained from a heat and material balance of the processing facility. A heating value and a molecular weight are determined for each relief source and flare header using a processing model associated with a relief source type, size, and identifications. The relief sources are connected using a data signal received and processed using the processing model. Reports are generated showing average daily heating values and molecular weights for each flare header. A real-time display is provided for monitoring instantaneous heating values and molecular weights for each flare header on a real-time basis.

Systems and methods include a computer-implemented method for real-time flare network monitoring. Real-time flaring volume data is received from relief devices connected to a flare network. The real-time flaring volume data is analyzed in conjunction with heat and material balance information of the relief devices. A comprehensive molar balance is performed based on the analyzing, the balancing including losses/feed percentages for each component of the flare network including the relief devices throughout the flare network. Flaring data for the components is aggregated for each flare header. Real-time flare network monitoring information, including instantaneous component-wise flaring for each flare header in the flare network is provided for display to a user in a user interface.

A cooking appliance that includes: a gas cooking element; an igniter located next to the gas cooking element to ignite the gas cooking element; a gas valve for regulating gas flow to the gas cooking element; a burner control coupled to the gas valve to vary the gas flow to the gas cooking element; and a control circuit coupled to the burner control and for activating the igniter when the burner control is positioned within a predetermined range of positions, where the control circuit detects when the burner control has been moved through the predetermined range of positions in less than a predetermined time, and in response to determining that the burner control has been moved through the predetermined range of positions in less than the predetermined time, generate an alert to a user.

Systems and methods for multi-variable flare control include receiving, at a flare controller, a plurality of flare characteristics from a flare monitor. The flare monitor may be an optical flare monitor. The plurality of flare characteristics may include, but are not limited to, Combustion Efficiency (CE), Smoke Index (SI), Flame Stability (FS), Flame Footprint (FF), and Heat Release (HR). The flare controller analyzes a plurality of the flare characteristics and outputs a control signal to control an operating condition of the flare, such as an amount of assist media being fed to the flare. Iterations of the control signal may be bounded by a step value defining a maximum increase or decrease in the control value as compared to the previous control value.
