Аннотация

This paper reports on the investigation of combustion features of synthesis gas/air and methane/air flames in a model gas turbine combustor with swirling flow via numerical simulation. This combustor developed for experimental investigation of flow, heat transfer and combustion. For synthesis gas combustion ratio of hydrogen and carbon monoxide was 1:1. The equivalence ratio Φ in both cases was 1.5. The combustor contains systems for water- and air-cooling that provides reasonable temperature value of combustor walls in operating mode. The methane/air flame has the lifted V-shape and synthesis gas/air flame has the columnar tubular flame. In practical, the V-shape flames are more often used. To provide more practical combustion regimes for synthesis gas/air mixture it is necessary to increase the fuel-oxidant mixing efficiency in the premixer of the combustor.
