Abstract: A system for combusting reactants. The system includes a low pressure combustor coupled to a low pressure line. Coupled to, and sitting atop the low pressure combustor is a high pressure combustor coupled to a high pressure line. The high pressure line is coupled to a flame arrester and an ignition source. The flame arrester is located a sub-sonic distance from the ignition source such that a flame arrester can be used as opposed to a flame detonator arrester. Further, the ignition source is retractable such that it can be removed, altered, repaired, etc., from the safety of the ground.

Abstract: A system for burning reactants. The burner has a burner shroud coupled to an upstream mixing tube. The burner shroud has swirlers. A gas coupler is upstream from the mixing tube, and the gas coupler has at least one air inlet and one air inlet adjuster. The air intake adjuster is adjustable relative to the air inlet such that the amount of air received by the air inlet can be controlled and adjusted. The burner can be coupled to the headspace of one tank and used to combust reactants collected in the headspace.
