Lean azimuthal flame combustor

摘要

A combustion chamber may include a first surface and a second surface interconnected by a wall forming a chamber having a central axis. The first surface may define an exhaust opening and the second surface defining a pilot opening, wherein the exhaust opening and the pilot opening align along the central axis. A plurality of inlet ports may be configured to deliver air to the chamber. A plurality of fuel ports may be arranged on an inside of the second surface to deliver fuel to the chamber. The air flow from the inlet ports and fuel from the fuel ports may oppose each other to create a vortex of product proximal to the second surface.

1. A combustor comprising:
a first surface and a second surface, parallel to the first surface, interconnected by a wall forming a chamber configured for combustion; the first surface defining a plurality of first openings, each first opening of the plurality of first openings comprising a frustoconical shape having an outer diameter and an inner diameter smaller than the outer diameter, and wherein at least one of air and fuel flow is configured to pass from the outer diameter through the inner diameter into the chamber; and the second surface defining a plurality of second openings configured to receive fuel, wherein air flow from the plurality of first openings and fuel from the plurality of second openings are injected in substantially opposite directions to create a vortex of product proximal to the second surface; wherein the chamber has a central axis, the first surface defining an exhaust opening configured to exhaust product from the chamber and the second surface defining an inlet opening configured to supply at least one of fuel and air to the chamber, wherein the exhaust opening and the inlet opening align along the central axis of the chamber and wherein at least one of the plurality of first openings and the plurality of second openings are arranged about the central axis.
