Conceptual Design of a Low-Emission Combustor for an Industrial Natural Gas Turbine with NO and CO Emission Less than 5 ppm

This paper presents an analysis of the hydrodynamic and physicochemical characteristics of flow and combustion in a low-emission combustor (LEC) that differs from other combustors in design and lean fuel–air combustion modes. The influence of the composition and residence time of the mixture in the...

Description
Summary:This paper presents an analysis of the hydrodynamic and physicochemical characteristics of flow and combustion in a low-emission combustor (LEC) that differs from other combustors in design and lean fuel–air combustion modes. The influence of the composition and residence time of the mixture in the LEC on NO  and CO emissions is considered. A LEC operation concept and demonstrator have been developed that provide NO  and CO emissions below 5 ppm, which is 2–5 times lower than that in available LECs. The results of experimental studies of the LEC demonstrator with varying flame temperature, pressure, and residence time in the LEC confirm the validity of the proposed solutions.
