Abstract: The grill of the present disclosure provides multiple heating zones within a front-to-back direction of each cooking platen. Each cooking zone has a heating element associated therewith. The heating elements can be independently controlled, so that each of the heating zones can be operated at a different temperature if necessary. A controller can monitor and adjust the heat output of each element with a temperature probe that measures the temperature of the surface of the grill plate. One or more of the heating elements can be a gas burner. Electrical heating elements may also be used.

Abstract: One or more techniques and/or systems are disclosed for an ignition control module for a gas appliance. The housing of the ignition control module, and/or the mounting points for mounting the module to a gas appliance, can be configured to dispose the battery in a manner that provides for potential battery leakage to flow away from most operable components of the module. Further, the ignitor connection terminals can be configured to provide for ease of connection, by providing a connector guide disposed in a cylindrically-shaped terminal housing. Additionally, an ignitor actuator terminal can be configured to selectably engage with an ignitor actuator connector, where the ignitor actuator terminal comprises at least two connector points that engage with a single ignitor actuator connector.

Abstract: A method of assembling a pilot burner assembly for use with a gas fired appliance includes inserting a retention element of a gas supply line through a slot defined by a retaining ledge of a second bracket plate, rotating an outlet orifice of the gas supply line such that the second retention element engages the retaining ledge, and inserting a pilot guard through first and second pilot guard apertures defined by respective first and second bracket plates such that a retention element of the pilot guard cooperatively engages the retention element of the gas supply line to maintain a connection between the pilot guard and the gas supply line.

Abstract: Provided is a combustion controller for a combustible gas of a pressurized water reactor nuclear power plant, and more particularly, to a combustion controller for a combustible gas installed in a rear end of a filtered vent system outside a containment vessel or an external chimney, configured to convert a combustible gas such as hydrogen, carbon monoxide, or the like, into steam, carbon dioxide, or the like, and simultaneously, operate by itself with no external power supply. Accordingly, the combustion controller for a combustible gas can perform stable combustion control with no probability of explosion of hydrogen through a recombining reaction of the combustible gas, prevent discharge of carbon monoxide, which is a toxic gas, and prevent backward flow of the flame through the quenching mesh.

Abstract: Burner holders and cartridges of a furnace are described herein, which include a support assembly and a manifold. The support assembly is configured to support one or more burners. For example, the support assembly may include a burner holder with a cutout region, which may allow a burner to be moved between an operational position and a disengaging position by twisting the burner. The cutout region can allow the one or more burners to be removed or installed relatively easily, without the need of removing the manifold from the support assembly. The manifold can be attached to the support assembly by, for example, using one or more orifices as fasteners.

Abstract: A mobile kitchen comprises a housing disposed atop one or more wheel axles and a plurality of appliances disposed within the housing. Each appliance is heated by combustion of a distillate fuel. One or more air channels are disposed about each of the appliances, such that each air channel substantially isolates excess heat from combustion of the distillate fuel from a workspace within the housing. One or more first air blowers are associated with the air channels, and each is adapted to force air through the air channels and vent the excess heat to the exterior of the housing. One or more second air blowers are coupled to the housing, and each second air blower is adapted to vent a predetermined volume of air from within the workspace at least once per minute.

Abstract: A cover member of a gas supply manifold has a bent rising wall portion that is formed by bending a part of the cover member so as to rise in an opposite direction of a main body. The bent rising wall portion is in a form of a loop surrounding the entire circumference of a gas supply flow path and an area around the gas supply flow path. Such configuration increases the rigidity of the cover member and prevents large distortion of the cover member and leakage of gas from the gas supply flow path. As a result, the thickness of the cover member is reduced and the weight and the production cost of the gas supply manifold are also reduced.

The feed injector includes one or more conduits extending toward a tip portion having an outlet, cooling coil coupled to the tip portion, and a protective shell including a first protective shell portion coupled to a second protective shell portion. The protective shell surrounds the tip portion and at least portions of the one or more conduits and the cooling coil. The feed injector also includes one or more mounting structures disposed along an outer perimeter of the feed injector. The one or more mounting structures may facilitate coupling of the first protective shell portion, the second protective shell portion, and the feed injector.

Abstract: A solenoid valve driving apparatus includes switching means for ON/OFF-controlling application of a direct current voltage to a solenoid of a solenoid valve, and signal outputting means. A first period and a consecutive second period are set as a valve opening operation period of the solenoid valve. When the signal outputting means outputs the PWM signal to the switching means, a duty ratio of the output signal is set to be higher in the second period than in the first period so that a power supplied to the solenoid is larger in the second period than in the first period. As a result, a valve opening operation is performed in the solenoid valve reliably, and loud noise generation during the valve opening operation is suppressed.

The damper control programmed processor is programmed to selectively open or close the damper responsive to status of a damper request register and to control status of a lockout register to indicate status of the damper. The appliance control programmed processor is programmed to control status of the damper request register responsive to a call for operation of the gas burner and to operate the gas burner only if the lockout register is set to unlock.

Abstract: A method and apparatus for controlling weeds using concentrated solar energy is disclosed. Solar energy may be concentrated by Fresnel lens and directed by manual or automated methods at surfaces of weed plants to heat portions thereof causing damage. Shutters or other devices may be used to direct, and control intensity of concentrated, solar energy, such control preferably applied before significant concentration. In some embodiments, solar energy concentration apparatus may be integrated with ground, air, or water vehicles which may use solar photovoltaic cells for electric power for propulsion and other purposes. Vehicles may use global positioning satellite (GPS) receivers or other methods and apparatus, including video cameras, for navigation and selection of areas (e.g., row middles), plants, or portions of plants to be exposed to concentrated solar energy. Air vehicles may use hydrogen gas electrolyzed from water condensed from humid air to replenish hydrogen gas lost from containment vessels.

The second baffle terminates at an outboard edge that is spaced apart from the stove's ceiling to define a flow area in a range of 0.5-1.0 times a cross-sectional area of the flue port.

Abstract: A method for staged combustion in a combustor assembly includes introducing an oxidant stream and a fuel stream at a first location into a combustion chamber to produce a heated stream. A Liquid water stream and an additional oxidant stream, fuel stream or both are then introduced into the heated stream in at least one location along the heated stream downstream from the first location. The additional oxidant stream, fuel stream or both react in the heated stream to generate additional heat that vaporizes liquid water from the liquid water stream to water vapor.
