SOFC-GT HYBRID SYSTEM - TURBOMACHINERY PROBLEMS

Further to analyses of external conditions the general requirements for a SOFC-GT Hybrid System for distributed generation use are presented (fuel - natural gas; locations - office buildings, hospitals, large stores, military bases; and capacity -4 -- 7 MW). The structure and parameters of the system are determined (at maximum efficiency). Optimization of the system parameters also determines the main parameters of turbomachinery needed. Off-design operation of the system is analyzed showing the range of turbomachinery parameter changes. General conclusions - it seems that turbomachinery for the SOFC-GT analyzed can be constructed successfully through the use of standard design techniques.
