A fuel supply component with coking mitigation includes a housing having a main fuel inlet and a main fuel outlet. The main fuel inlet and outlet define a main fuel flow path therebetween. The housing includes a de-oxygenated fuel inlet in fluid communication with the main fuel flow path downstream from the main fuel inlet. The de-oxygenated fuel inlet is configured and adapted to supply de-oxygenated fuel to the main fuel flow path to mitigate insoluble fuel elements from diffusing and adhering to a wall of the housing.

A burner apparatus and process are described. The burner apparatus includes an inlet chamber in communication with a combustion chamber. A primary conduit delivers fuel gas to the combustion chamber. Each of a plurality of primary tips is located in the throat of the burner tile. Each of a plurality of cavities is disposed on a downstream wall of the burner tile and stabilize the flame. The primary tips have an end port and a lateral port. A secondary conduit provides fuel gas to a plurality of secondary tips. In a passive control mode, the fuel gas to the primary tips and secondary tips is a mixed gas comprising flue gas and fuel gas. In an active mode, valves are provided to proportion the amount of fuel gas fed to the primary tips and the amount of flue gas provided to the secondary tips.

Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.
