Abstract

A simple combustor with ultra low NOx has a substantially cylindrical liner forming a chamber therein for containing a combustion zone. The liner does not permit a fuel stream to flow through it and into the combustion zone. The combustor nozzle is centrally disposed in the combustor. A flow guide is disposed between the liner and the fuel nozzle, forming a first inlet passage for the chamber. A first portion of the first inlet passage is formed between the flow guide and the liner and extends axially and is concentric with the liner. A second portion of the first inlet passage extends radially and encircles the first inlet passage first portion. A second inlet passage for the chamber also has two portions. The first portion of the second inlet passage is formed between the fuel nozzle and the flow guide and extends axially and is concentric with the first portion of the first inlet passage. The second portion of the second passage extends radially and encircles the first portion of the second inlet passage.
