A gas burner assembly includes a gas burner. A grate with a plurality of fingers is positioned above the gas burner. A sensor finger of the plurality of fingers defines an open downward facing slot at a bottom of the sensor finger. A temperature sensor is mounted to the sensor finger at a first end portion of the slot. A pogo pin terminal block is mounted to the grate at a second end portion of the slot. A wire extends between the temperature sensor and the pogo pin terminal block within the slot.

The gas turbine with a plurality of combustors for igniting gas and method includes receiving first temperature measurements for a first plurality of probing points, each associated with one of the plurality of combustors. The method includes receiving second temperature measurements for a second plurality of probing points, each located downstream of the plurality of combustors. The method includes determining an association between the first plurality of probing points and the second plurality of probing points. The determining includes using the first and second temperature measurements and position information for the first and second plurality of probing points to determine swirl characteristics for the gas turbine. The swirl characteristics representing the angular shift between the ignited gas at the plurality of combustors and the ignited gas at the second plurality of probing points.

A gas appliance includes a burner, a gas valve, an igniter, a thermocouple, and a control device. The control device is adapted to execute a control method comprising the following steps: controlling the igniter to ignite and controlling the gas valve to open; receiving a detected voltage output from the thermocouple; controlling the igniter to stop igniting and keeping the gas valve open when the detected voltage reaches a first voltage value; receiving the detected voltage output from the thermocouple continuously, and controlling the gas valve to close the gas pipe when the detected voltage above a second voltage falls below the second voltage. The second voltage value is higher than the first voltage value. As such, an ignition procedure may be speeded up and the supply of the fuel gas may be interrupted more quickly when the flame is extinguished.

An electromagnetic valve has a magnetic coil and a movable element coupled to a valve element. The magnetic coil, when excited, conveys the movable element in one direction to move the valve element from its initial position into its active position. A control circuit for the electromagnetic valve has a current source for optionally supplying current to the magnetic coil and a measuring device for measuring a voltage level of the magnetic coil and/or a current level through the magnetic coil. A monitoring unit which is connected to the measuring device establishes a switching state of the electromagnetic valve corresponding to the position of its valve element based on the intended current supply state of the current source and the current and/or voltage characteristic measured by the measuring device and, if appropriate, determines a fault state of the current supply and/or the electromagnetic valve.

A burner includes a mixing chamber having therein a space in which fuel and air are mixed to form a mixture, a chamber lower cover that is coupled to the mixing chamber while covering an opening formed in the mixing chamber in a reference direction and has a combustion opening opened in the reference direction, a porous distribution unit that includes a metallic sintered material, through which the mixture passes in the reference direction, and covers the combustion opening, a distribution plate that has a plurality of distribution through-holes, through which the mixture passing through the porous distribution unit passes, and covers the combustion opening on the downstream side of the porous distribution unit in the reference direction, and an ignition unit that covers the combustion opening on the downstream side of the distribution plate to ignite the mixture passing through the distribution plate.

Sparkless igniters comprising a hot surface igniter assembly and a nozzle that produce a flame plume with diameter substantially similar to the diameter of the fire tube, and flame length less than the length of each leg of the U-shaped fire tube in heater treaters are applicable to both vertical and horizontal heater treaters and improve the durability of fire tubes while reducing igniter fuel consumption by at least 30%.

A gas range has burner head which have temperature sensing devices as a portion of the burner heads. Upon reaching a predetermined temperature, the temperatures sensing devices reduces gas flow to a bypass amount until temperature drops below to at least the predetermined temperature. Lowering the temperature in a cooking utensil below a common ignition temperature, while still allowing boiling, is an objective of many embodiments.

Embodiments disclosed herein are directed to devices and methods for improving operation of a combustion system.

A gas burner assembly and a method of operating the same are provided. The gas burner assembly includes fuel valve for providing a flow of fuel and an air pump for providing a flow of air into a boost fuel chamber prior to combustion. The method includes obtaining a predetermined cold start airflow schedule and modifying the cold start airflow schedule if the operating history of the gas burner assembly indicates that the temperature of the gas burner assembly is elevated, e.g., not cold. Specifically, the warmer the gas burner assembly, the more the airflow is increased relative to the cold start airflow schedule.
