Acetylene Production By Staged Combustion With Accommodative Cross-Sectional Area

A method for producing a chemical, comprising:

• firing a first jet within a combustion chamber at a first jet angle, the first jet angle defined by one or more first inlets through a sidewall of the combustion chamber, the first jet is fired by providing fluid through the one or more first inlets, the first jet is an axial jet;
• and
• firing two or more second jets within a chamber at two or more second jet angles, the two or more second jet angles defined by two or more second inlets through the sidewall of the combustion chamber, the two or more second jets are fired by providing fluid through the one or more second inlets, the two or more second jets are radial jets;
• and
• providing feedstock into the combustion chamber during combustion through a process feed, the feedstock is processed into at least a portion of a product output from the combustion chamber, wherein a firing rate of about 30 MMBtu/h to about 1000 MMBtu/h is exhibited in the combustion chamber.

A system, comprising:

• a combustion chamber having a chamber structure including sidewalls, the sidewalls having at least a first section and a second section, the first section having a varying first cross-section and the second section having a second cross-section;
• a first stage having one or more first inlets, the one or more first inlets having one or more first inlet directions incident to respective areas of the sidewalls at one or more first inlet angles, the one or more first inlets configured to provide fluid for combustion in the combustion chamber, the first stage producing one or more of an axial jet and a radial jet within the combustion chamber;
• a second stage having one or more second inlets, the one or more second inlets having one or more second inlet directions incident to respective areas of the sidewalls at one or more second inlet angles, the one or more second inlets configured to provide fluid for combustion in the combustion chamber, the second stage producing a radial jet within the combustion chamber;
• a process feed for providing a feedstock acted upon by the combustion within the combustion chamber;
• an output for providing product based at least in part on the fluid;
• and
• a cooling structure about at least a portion of the chamber, wherein a firing rate of about 30 MMBtu/h to about 1000 MMBtu/h is exhibited in the combustion chamber.
