The flowback system, in one aspect, include a tank, a transfer pump, a low-pressure vent line coupled between a vent of the tank and a first flare tip, and a high-pressure gaseous hydrocarbon line coupled to a second flare tip. In accordance with yet one other aspect, the flowback system includes a control system including a sensor, a valve and a valve controller coupled to the valve, the valve of the control system coupled between the low-pressure vent line and the high-pressure gaseous hydrocarbon line, the control system configured to sense an unsafe system event and actuate the valve to supply high-pressure gaseous hydrocarbons from the high-pressure gaseous hydrocarbon line to the low-pressure vent line.

The present invention relates to an electromechanical system for automating the turning off of the knobs of a stove. The system can quickly identify the occurrence of a gas leak and turn off the knob corresponding to the burner that is leaking. The system is also connected to a user interface, providing real-time information about the status of the burners and allowing the user to turn off the knobs remotely. The system has an improved service life, does not considerably change the aesthetics of the stove and can be designed to fulfil different torque requirements. The invention also relates to cooktops comprising said system.

An adjustable injector system for adjusting a radial distribution of a mixed fuel includes an adjustable injector configured to receive first and second non-carbon fuels and configured to adjust the radial distribution of the mixed fuel with a movable part, wherein the mixed fuel is obtained from mixing the first non-carbon fuel with the second non-carbon fuel; a sensor configured to determine an instability of a flame generated by the mixed fuel; and a controller electrically connected to the adjustable injector and the sensor, and configured to change a configuration of the adjustable injector, based on an input signal from the sensor, to control the radial distribution of the mixed fuel.

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.

A cooking appliance and method control the power consumption of a plurality of electrical loads in response to an ambient temperature sensed by a temperature sensor to maintain a combined power consumption within a temperature-dependent output capability of a low voltage power supply used in the cooking appliance.

A method for operating a gas turbine engine includes receiving data indicative of an operational vibration within a section of the gas turbine engine; and providing electrical power to a shaker mechanically coupled to one or more components of the section of the gas turbine engine to generate a canceling vibration to reduce or minimize the operational vibration within the section of the gas turbine engine.

A cooking appliance may use a sensor to sense a rate of movement of a user control and generate an alert when the rate of movement meets an alert criterion, thereby enabling detection of potential inadvertent movements of a user control.

According to some embodiments gas cooking appliances are provided that include at least one burner, an electrode, and a push button unit with a push button for activating the electrode. A gas valve is provided for each burner for regulating gas flow arriving from a gas conduit. An electromagnetic shut-off valve is arranged in the gas conduit and includes a closure member for closing the passage of gas. A control unit controls the shut-off valve. The closure member includes a stable closed position and a stable open position, the closure member changing position upon receiving electric current pulses. The push button unit is configured for pushing the closure member of the shut-off valve to the open position while at the same time activating the control unit and the electrode when the push button is pressed when the gas cooking appliance off. The control unit controls the shut-off valve by means of electric current pulses once the push button has been pressed.

The present disclosure relates to a control method of a gas furnace comprising a step for measuring an indoor temperature, a step for comparing the indoor temperature with a set temperature for heating, and a step for operating the gas furnace in weak heating with a predetermined heating capacity which is lower than a maximum heating capacity of the gas furnace, when the set temperature for heating is higher than the indoor temperature by a temperature value which is less than a predetermined temperature value, wherein the predetermined heating capacity for weak heating is maintained at a current heating capacity for weak heating, when the gas furnace operates in weak heating, and when an operating duration with the current heating capacity for weak heating is less than a first time value.

A furnace includes a gas burner exposed to a heat-exchange tube. An inducer is fluidly coupled to the heat-exchange tube and configured to induce draft air through the heat-exchange tube. A regulator is fluidly coupled to the gas burner. A rollout shield is disposed adjacent to the gas burner. A rollout switch is disposed in the rollout shield. The rollout switch is electrically coupled to the regulator. At least one vent is formed through the rollout shield adjacent to the rollout switch. The vent provides a path for a rollout flame to the rollout switch. The at least one vent is disposed on at least two sides of the rollout switch.
