Abstract

The present invention is applied to a technique which involves nitrogen cooled generator system for an Integrated Gasification Combined Cycle (IGCC) plant. The generator comprises an air separation unit (ASU) which separates nitrogen from air. The nitrogen is can then be used as a coolant in the generator system. Nitrogen absorbs heat from the generator and further compressed to the combustion pressure levels using a diluent gaseous nitrogen (DGAN) compressor. Nitrogen being an inflammable gas and having a high thermal conductivity is used as an alternative coolant for cooling the generator system.
