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.

Systems and methods for operating a gas-fired appliance such as a gas-fired cooking grill are provided. An embodiment of the system includes a gas burner for heating a chamber of the gas-fired appliance. The system includes a first valve associated with the gas burner to control a gas flow to the gas burner. The system includes a second valve configured to controllably supply gas to the gas burner via the first valve. The second valve is automatically adjustable based on a desired temperature of the chamber and an actual temperature of the chamber.

Disclosed is a dual-fuel heater having one or more thermocouples that operate a control valve that, in turn, controls whether fuel is distributed from a regulator to a burner based on the signal generated by the thermocouple(s). Further disclosed is a primary fuel selector valve that selects the fuel being used based on the operation of a user. The primary fuel selector valve provides fuel to the control valve upstream from the thermocouples, allowing for upstream control mechanisms such as a slave valve, to control the flow of fuel to the control valve.

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.
