Pure oxygen combustion three-fluid gas turbine for power generation

Abstract

The present disclosure provides a pure oxygen combustion three-fluid gas turbine for power generation, in which fuel gas, oxygen and steam in the combustion chamber are respectively controlled as required; there is no need for a complex airflow passage design and flow regulation and control; the pure oxygen combustion three-fluid gas turbine for power generation has a simple structure, a low cost, is easy to manufacture and assemble, and sets a basis for COrecovery with low-energy consumption; for the first time, steam circulation is used to control the combustion temperature with low energy consumption, and steam cooling is also used to cool the moving blades and stationary vanes at low cost; besides, the initial combustion temperature can be improved by more than 100° C. with an equivalent high-temperature material, thereby the problem of steam cooling in existing gas turbines is solved.
