THERMODYNAMIC POWER GENERATION SYSTEM EMPLOYING A THREE COMPONENT WORKING FLUID

摘要

A system for generating power as a result of an expansion of a pressurized working fluid through a turbine exhibits improved efficiency as the result of employing a tri-component working fluid that comprises water, ammonia and carbon dioxide. The pH of the working fluid is maintained within a range to prevent precipitation of carbon-bearing solids (preferably between 8.0 to 10.6). The working fluid enables an efficiency improvement in the Rankine cycle of up to 12 percent and an efficiency improvement in the Kalina cycle of approximately 5 percent.
