摘要

A new annular RQL combustion chamber of an 80 kWel Elliott TA80R micro gas turbine was designed and validated by means of CFD simulations of natural gas combustion on modified geometries to overcome known failures at low running hours (around 2500 hrs) caused by overheating. This work provides the results of the design optimization on some geometrical parameters for fuel injection, air-fuel mixing and mixture combustion. Moreover, the new design considered simplified manufacturability and flow optimization to reduce emission while maintaining similar temperatures and efficiencies. The new combustor can easily be built with affordable overall gross costs ? guaranteeing similar TIT with respect to the original geometry and with a considerable reduction of NOx emission.
