The present disclosure relates to systems and methods that are useful for controlling one or more aspects of a power production plant. More particularly, the disclosure relates to power production plants and methods of carrying out a power production method utilizing different fuel chemistries. Combustion of the different fuel mixtures can be controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel chemistries.

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 foldable foot pivotally coupled to and extending between the first and second legs. The foldable foot is movable relative to the first and second legs between an unfolded configuration and a folded configuration. The foldable foot contacts an underlying surface to support the portable grill when the foldable foot is unfolded and the portable grill is erected and oriented horizontally relative to the underlying surface. The foldable foot provides a handle by which the portable grill can be picked up when the foldable foot is folded and the portable grill is collapsed and oriented horizontally relative to the underlying surface.

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.

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame, a cookbox, a lid, and a lid lock assembly. The cookbox is coupled to the frame. The lid is movably coupled to the cookbox. The lid is movable relative to the cookbox between a closed position and an open position. The lid lock assembly is coupled to the frame. The lid lock assembly is configured to enable movement of the lid from the closed position into the open position when the portable grill is in the erected configuration, and to lock the lid in the closed position in response to the portable grill being moved from the erected configuration into the collapsed configuration.

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a valve and regulator assembly and a tank blocker. The valve and regulator assembly includes a tank connector configured to removably couple a fuel tank to the valve and regulator assembly. The tank blocker is configured to prevent the portable grill from being moved from the erected configuration into the collapsed configuration when the portable grill is in the erected configuration and the fuel tank is coupled to the tank connector.

Portable grills are disclosed. An example portable grill movable between an erected configuration and a collapsed configuration includes a frame, a leg unit, and a leg lock assembly. The leg unit is movably coupled to the frame. The leg unit includes a first leg and a second leg spaced apart from the first leg. The leg lock assembly is operatively coupled to the leg unit and located partially within the frame. The leg lock assembly is configured to lock the leg unit in a first position relative to the frame when the portable grill is in the erected configuration, and to unlock the leg unit from the first position to enable movement of the portable grill from the erected configuration into the collapsed configuration.

Portable grills are disclosed. An example portable grill includes a cookbox, a lid, a cooking grate, and a grate retainer. The lid is movably coupled to the cookbox, and is movable relative to the cookbox between a closed position and an open position. The lid and the cookbox define a cooking chamber when the lid is in the closed position. The cooking grate is located within the cooking chamber and supported by the cookbox. The cooking grate is movable relative to the cookbox when the lid is in the open position. The grate retainer is coupled to the lid, and extends inwardly from an inner surface of the lid. The grate retainer is configured to restrict movement of the cooking grate relative to the cookbox when the lid is in the closed position.

A method, control unit and rotating machine for determining a fuel split setting value for adjusting a fuel split setting for a combustion device, the fuel split setting defining a relation between main fuel and pilot fuel. The method includes: retrieving a first information item correlated to heating value of supplied main fuel; retrieving a second information item correlated to combustor operating condition; retrieving at least one third information item representing stability of combustion; selecting a predefined pair of minimum and maximum boundary curves for the fuel split setting from a plurality of predefined pairs based on the first and second information items, the minimum and maximum boundary curves defining a band of fuel split settings permitted for a range of second information item values; determining the fuel split setting value within the selected pair of minimum and maximum boundary curves based on the third information item.
