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.

A control device of a hydrogen gas burner device sets a target flow rate of a hydrogen gas such that a flow rate of the hydrogen gas decreases as a temperature of the hydrogen gas becomes higher, based on the temperature of the hydrogen gas and a needed quantity of heat of the hydrogen gas during the combustion, sets a target flow speed such that the flow speed of the hydrogen gas released from a combustion nozzle via a flow speed regulator becomes a flow speed based on the target flow rate and the flow speed of the hydrogen gas increases as a value of the target flow rate decreases, controls the flow rate regulator such that the flow rate of the hydrogen gas reaches the target flow rate, and controls the flow speed regulator such that the flow speed of the hydrogen gas reaches the target flow speed.
