説明

The lean-lean two stage combustion, characterized by the enhancement of the reactions of ultra-lean to lean mixtures injected into the hot combustion products of the lean-burn primary stage, was investigated to show its potential in achieving low NOx emissions while maintaining complete combustion over a wide range of power of gas turbines. For single-digit NOx emissions, the stagnation reverse flow combustion was employed as a means of flame stabilization for the primary stage because of its robust flame holding capability at very lean conditions. Methane was used as fuel and emissions measurements and direct flame imaging were conducted at Ti = 600 and 750 K and at atmospheric pressure. NOx emissions less than 2 ppm (15% O2) were achieved for a primary equivalence ratio of 0.7 with combustion efficiency greater than 99.9% over a range of gas temperatures ranging from 1500 to 1800 K.
