Ammonia–water power cycles for direct-fired

The ammonia–water cycle approaches the Rankine steam cycle when a high supply temperature is desired. For a cogeneration plant without reheat, the difference in net power generation is between 4 and 11%. With condensing power application, the ammonia–water cycle reaches higher power generation than the Rankine steam cycle.
