Abstract:
1. A system, comprising: a gasifier having a chamber comprising a combustion-reduction zone; a first nozzle disposed along a central axis of the gasifier, wherein the first nozzle is configured to supply a first fuel and an oxidant to create a mixture in the combustion-reduction zone, and wherein a portion of the mixture is configured to oxidize to generate a flame within the combustion-reduction zone; a second nozzle disposed off-axis to the central axis of the gasifier, wherein the second nozzle is configured to supply a reduction promoter to the combustion-reduction zone, wherein the reduction promoter is configured to reduce combustion products within the combustion-reduction zone; and a gasification controller configured to control flow of the reduction promoter through the second nozzle into the gasifier to increase a methane production by chemically reducing the combustion products generated from the first fuel in response to one or more sensed parameters, wherein the combustion products comprise syngas, wherein at least one of the sensed parameters is indicative of a temperature of the flame, wherein the gasification controller is configured to control a fuel ratio between the first fuel and the reduction promoter, wherein the gasification controller is configured to control the fuel ratio based at least partially on the temperature of the flame.
