CYCLE OPTIMIZATION AND COMBUSTION ANALYSIS IN A LOW-NO{sub}x MICRO-GAS TURBINE

摘要

The authors discuss in this paper the potential of a method for NO{sub}x suppression from power plants based on micro-gas turbines. The method is based on the mild combustion concept, but it needs to be adapted to the actual operating parameters of the micro-turbine, so resulting in an effective employment of the flue gas recirculation for diluting the oxygen in the inlet air. The results are first presented on a thermodynamic basis and some cases are then analyzed with a CFD simulation. Both approaches suggest good perspectives for the nitric oxide control but also highlight some disadvantages in terms of increase in carbon species.
