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.

An ammonia combustion method for combusting ammonia gas in a combustion chamber 4 includes steps of separating and producing hydrogen gas from ammonia gas, supplying the separated and produced hydrogen gas into the combustion chamber 4, combusting the hydrogen gas by performing an ignition discharge on the hydrogen gas supplied into the combustion chamber 4, and igniting the ammonia gas in the combustion chamber 4 from the combusted hydrogen gas.

A cooktop appliance includes a first burner and a second burner which are spaced apart with a grate positioned above the burners. The grate includes a first sensor finger with a first temperature sensor over the first burner and a second sensor finger with a second temperature sensor over the second burner. The cooktop appliance also includes a first control valve and a second control valve which selectively direct fuel to the respective burners. A controller of the cooktop appliance is operably coupled to the temperature sensors and the control valves. The controller may be operable for and/or methods of operating the cooktop appliance may include receiving a set temperature, receiving a first temperature measurement from the first temperature sensor and a second temperature measurement from the second temperature sensor, and adjusting each control valve based on the set temperature and the corresponding temperature measurement.

A gas manifold assembly for delivering fuel from a fuel source to a burner assembly includes a gas manifold tube configured to deliver fuel from the fuel source and a stub tube mounted to and arranged in fluid communication with the burner assembly. An end of the gas manifold tube is connectable to the stub tube to form a slip joint.

A method of operating a multi-ring gas burner includes sending a spark to a first ring of the multi-ring burner. After sending the spark to the first ring, the method determines a flame status of the first ring and adjusts a position of an electronic gas valve connected to a second ring of the multi-ring gas burner based on the determined flame status of the first ring.

A hydrogen chloride loop fuel reaction is designed and configured for turbine/generator combination which can be used for automotive propulsion or as a standalone electrical generation or for auxiliary equipment. A method for providing a hydrogen chloride loop fuel reaction includes creating hydrogen chloride fuel in a sealed furnace vessel, wherein at start up, the sealed furnace vessel is vacuumed out and hydrogen and chlorine are injected into a burner and ignited resulting in the hydrogen chloride fuel in an exhaust stream of the sealed furnace vessel; and looping the hydrogen chloride fuel leaving the sealed furnace vessel in the exhaust stream of the sealed furnace vessel.

The premixing device includes a first and a second venturi having a pressure reducing portion for air, and a gas supply passage for supplying fuel gas to the venturis, and generates air-fuel mixture by mixing fuel gas with air flowing in the venturi by using a fan and supplies the air-fuel mixture to a burner. A first and a second nozzles for reducing pressure of fuel gas are disposed in the gas supply passage, and the first and the second nozzles are formed in the same nozzle shape as the pressure reducing portion of the first and the second venturis.
