Abstract
A burner apparatus and process are described. The burner apparatus includes an inlet chamber in communication with a combustion chamber. The combustion chamber has a cylindrical shape defining a longitudinal axis and a radial direction orthogonal to the longitudinal axis. The combustion chamber has an upstream end and a downstream end, and an air inlet is disposed in the inlet chamber. A pilot, a fuel gas inlet, and a refractory material are disposed in the combustion chamber downstream of the air inlet. A mixed gas inlet is positioned downstream of the fuel gas inlet and the pilot in the combustion chamber. The mixed gas inlet includes a manifold having an inlet, a body, and a plurality of nozzles.
Claims19
A burner apparatus comprising:
- an inlet chamber in communication with a combustion chamber;
- the combustion chamber having a round cross section and a longitudinal axis, combustion chamber having a radial direction orthogonal to the longitudinal axis, the combustion chamber having an upstream end and a downstream end;
- an air inlet disposed in the inlet chamber;
- a pilot, a fuel gas inlet disposed in the wall of the combustion chamber, and a refractory material disposed in the combustion chamber downstream of the air inlet and the pilot;
- and
- a mixed gas inlet positioned in the combustion chamber downstream of the fuel gas inlet, the mixed gas inlet comprising a manifold having an inlet and a body,
- wherein the body of the manifold extends completely around a circumference of the combustion chamber downstream of the fuel gas inlet.
A burner apparatus for comprising:
- an inlet chamber in communication with a combustion chamber;
- the combustion chamber having a cylindrical shape having a longitudinal axis and a radial direction orthogonal to the longitudinal axis, the combustion chamber having an upstream end and a downstream end;
- an air inlet disposed in the inlet chamber;
- a pilot, a fuel gas inlet disposed in the wall of the combustion chamber, and a refractory material disposed in the combustion chamber downstream of the air inlet and the pilot;
- and
- a mixed gas inlet positioned in the combustion chamber downstream of the fuel gas inlet, the mixed gas inlet comprising a manifold having an inlet, a body, and a plurality of nozzles,
- wherein the body of the manifold extends completely around a circumference of the combustion chamber downstream of the fuel gas inlet.
A burner process comprising:
- injecting air into an air inlet of a burner apparatus, the burner apparatus having an inlet chamber in communication with a combustion chamber, wherein the air inlet is disposed in the inlet chamber, and a pilot, a fuel gas inlet disposed in the wall of the combustion chamber, and a mixed gas inlet are disposed in the combustion chamber downstream of the fuel gas inlet, and wherein the combustion chamber is lined with a refractory material and has a cylindrical shape defining a longitudinal axis and a radial direction orthogonal to the longitudinal axis, the combustion chamber having an upstream end and a downstream end;
- injecting a mixed gas stream into the mixed gas inlet, the mixed gas inlet disposed downstream of the fuel gas inlet, the mixed gas inlet comprising a manifold having an inlet, a body, and a plurality of nozzles, wherein the body of the manifold extends completely around a circumference of the combustion chamber downstream of the fuel gas inlet;
- and
- combusting air and fuel gas in the combustion chamber.
