Abstract
The objective of this work is to suggest a method for optimizing the compressor and turbine components in hybrid SOFC-GT (Solid Oxide Fuel Cell - Gas Turbine) applications. The hybrid system evaluations are made on the basis of a typical SOFC generator scheme without any modifications. The method consists of two steps. A parametric study is conducted in order to assess the operating range of the hybrid SOFC-GT system and select the desired operating line for achieving the optimum system efficiency at various operating points. Based on that information, optimum compressor and turbine geometries are estimated using in-house turbomachinery design codes and an optimization procedure. The new components ensure the best performance not only in the design point but also during part-load operation. The results of the present analysis are useful for designing hybrid SOFC-GT systems based on a fixed SOFC generator design.
