Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame and a leg unit coupled to the frame. The leg unit includes a first leg, a second leg spaced apart from the first leg, and a support bar coupled to and extending between the first and second legs. The support bar further extends at an angle away from the first and second legs. The support bar is configured to contact an underlying surface to support the portable grill when the portable grill is in the collapsed configuration and oriented horizontally relative to the underlying surface. The support bar is further configured to provide a handle by which the portable grill can be hung when the portable grill is in the collapsed configuration and oriented vertically relative to the underlying surface.

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.

According to one aspect, a cooking apparatus having a main fuel manifold that provides fuel to at least one manual burner and at least one control valve, and at least one controlled fuel manifold in fluid communication with the at least one control valve, each controlled fuel manifold for providing fuel to at least one controlled burner. The cooking apparatus also includes at least one thermocouple, each thermocouple monitoring at least one measured temperature within the cooking apparatus. The cooking apparatus also includes an input device for receiving a desired temperature set-point. The cooking apparatus also includes a controller having a microprocessor operable to compare the at least one measured temperature and the temperature set-point. In response to the comparison, the controller will selectively adjust the at least one control valve to restrict an amount of fuel flowing to the at least one controlled fuel manifold.

A temperature display and/or control system is disclosed for a cooing apparatus, such as a grill, comprising a plurality of individual zones to provide individual zone temperatures. Each zone of the grill is associated with a temperature sensor, such as a thermocouple, and a visual indicator to indicate the zone temperature, such as control knob bearing a multi-color LED. A controller obtains a signal from the temperature sensor indicating a raw temperature and converts the raw temperature to an actual zone temperature based on a temperature profile selected for the zone. The temperature profile is configurable for each zone based on a configuration of the zone in order to maintain an accurate temperature conversion despite alterations to an environment.

Systems, methods, and circuitries are provided for a controller for a fuel oil burner system that controls a fuel oil burner to perform intermittent ON cycles. In one example, a controller includes a memory configured to store a value for one or more burner control delay periods and a processor. The processor is configured to perform an auto-set procedure in a first ON cycle. The auto-set procedure includes detecting an oil valve in the fuel oil burner; determining that the value for a burner control delay period is a default value; and in response, storing a valve-present value as the value for the burner control delay period in the memory.

Example methods and apparatus for automating startup processes of gas grills are disclosed. An example grill includes a first burner, a second burner, a first burner valve operatively positioned between the first burner and a manifold of the grill, a second burner valve operatively positioned between the second burner and the manifold, a first ignitor operatively positioned relative to the first burner, and a second ignitor operatively positioned relative to the second burner. The example grill further includes a controller operatively coupled to the first burner valve, the second burner valve, the first ignitor, and the second ignitor. In response to determining that a user-based startup request has been received at the grill, the controller is to instruct the first burner valve and the second burner valve to open, and instruct the first ignitor and the second ignitor to ignite corresponding ones of the first burner and the second burner.

Example methods and apparatus for automating shutdown processes of gas grills are disclosed. An example grill includes a first burner, a second burner, a first burner valve operatively positioned between the first burner and a manifold of the grill, and a second burner valve operatively positioned between the second burner and the manifold. The example grill further includes a controller operatively coupled to the first burner valve and the second burner valve. In response to determining that a shutdown request has been received at the grill, the controller is to instruct the first burner valve and the second burner valve to close.

An electronically controlled burner management system for oilfield process equipment. The system includes a vessel fluid temperature sensor and electronic valve for interruption of main burner fuel flow. When process equipment is retrofitted with this system total gas production is increased, reduces fugitive emissions of unburned gas, and reduces hazards. The system integrates with existing pneumatic thermostatic control, making it easy to control and can be bypassed in the event of failure.

The disclosure provides a combustion device for burning LP gas filled in a gas cylinder as fuel in a combustion unit. The combustion device includes: a control unit for controlling a combustion operation based on a preset operation table such that a combustion output reaches a target output, and an output detection part for detecting the combustion output. In a case where the combustion output detected by the output detection part is risen by a reference value or more relative to the target output, the control unit notifies of a lowering in the remaining amount of LP gas in the gas cylinder.

A gas valve for a cooking appliance is provided and includes a valve housing defining a valve chamber therein. A plug is disposed within the valve chamber. A valve stem interacts with the plug such that rotation of the valve stem correspondingly rotates the plug to selectively permit a flow of gas through the gas valve. The valve stem is axially translatable between a locked position wherein rotation thereof is inhibited and an unlocked position wherein rotation thereof is permitted. A first spring exerts a compressive force against the valve stem, toward the plug, to bias the valve stem into the locked position. A second spring exerts a compressive force against the plug in order to seat the plug within the valve chamber regardless whether the valve stem is in the locked or the unlocked position.
