COMBINED-CYCLE POWER GENERATION THERMODYNAMIC SYSTEM

摘要

The embodiments herein provide a system and a method for power generation using combined cycle technology with two power blocks. A part of the heat available in a first working media in a first power block after expansion is used to heat a second working media in a second power block using a heat recovery unit and the remaining heat is internally recuperated within the first power block. The working media comprises oxygen rich media and burnt fuel in the first power block and carbon dioxide and/or other mixtures in the second power block. The selection of these media, the architectural configurations and the operating conditions lead to a substantial increase in overall efficiency of the combined cycle technology thereby approaching the thermodynamic efficiency limit.
