Gradual oxidation with adiabatic temperature above flameout temperature

摘要

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.

主权项

1. An oxidizer for oxidizing fuel, comprising:
a reaction chamber having (i) one or more inlets that are configured to direct at least one gas of a fuel, oxidant, or diluent, into the reaction chamber and (ii) one or more outlets that are configured to direct reaction products from the reaction chamber; a heater that is configured to maintain a temperature of the at least one gas, the at least one gas being at or before the one or more inlets, to be above an autoignition temperature of a resulting mixture, comprising the at least one gas, within the reaction chamber, wherein the reaction chamber is configured to oxidize the resulting mixture; and a controller configured to output instructions to the reaction chamber to maintain a calculated adiabatic temperature within the reaction chamber above a flameout temperature of the resulting mixture and a maximum reaction temperature within the reaction chamber below the flameout temperature of the resulting mixture.
