دانلود Off-design point characteristics of the precooled gas turbine cycle with liquefied hydrogen as fuel

Abstract

The off-design  point  performance  of  a  precooled  gas  turbine cycle fueled  with  liquid  hydrogen  is analyzed.  The gas turbine equips the precooler  and hydrogen turbine in order  that  the cryogenic exergy (available energy)  can  be  effectively  converted  to  useful  work. The  design  point  is  determined  by  using  an  estimating function,  F.  The thermodynamic  analysis reveals that  even at the off-design point working conditions the  thermal efficiency of this cycle is also relatively high compared  to that of conventional gas turbine cycle and the load factor decreases  in keeping  with the  decrease  in the  temperature  of the  working fluid at  the  inlet of the  gas  turbine.
