Steady-state and transient compressor surge behavior within a SOFC-GT-hybrid system
(2004) 2004 ASME Turbo Expo 7. p.541-550- Abstract
- Future pressurized Solid Oxide Fuel Cell- (SOFC) Gas Turbine Hybrid Systems (HS) promise high efficiency at both full-and part-load on account of the upper and lower SOFC temperature limit and the compressor surge line [1]. The compressor surge constraint is also evident in transient HS operation, caused by the slow transients of SOFC temperature imposed by large SOFC plenum, and fast turbo-machinery transients. This paper presents steady-state and unsteady-state HS modeling and calculation results with regard to surge. The transient compressor and SOFC models have been validated against literature. Calculation results of the coupled SOFC-GT-HS reveal a small operational window in case of unmatched turbine and the critical transient... (More)
