An Optimization-Based Approach for the Development of a Combustion Chamber for Residential Micro Gas-Turbine Applications

Abstract

In the field of micro gas turbine, attention must be paid on the design of the combustion chamber to reduce NO_x formation without compromising combustion efficiency. To this goal flameless combustion represents an appealing solution. The present work aims at the design and optimization of a combustion chamber for a micro gas-turbine, operating in flameless combustion regime. The feasibility of such system is analysed with numerical simulations, using CFD-tools. Among the several configurations under investigations, it is possible to identify one that guarantees the maximum combustion efficiency, the minimum pressure losses as well as the minimum overall dimension.
