GENERATING SYSTEM HAVING SUPER CRITICAL FLUID TURBINE-STEAM POWER HYBRID SYSTEM

摘要

A power generation system including a supercritical fluid turbine-steam power hybrid system is disclosed. The power generation system (100) according to an embodiment of the present invention comprises: a compressor (111) which compresses air; a combustor (112) in which fuel and the air discharged from the compressor (111) are burned; and a turbine (113) which is driven by the fuel gas discharged from the combustor (112). A cooling flow path (114) is installed in the combustor (112) and the turbine (113), a supercritical fluid is allowed to flow as a cooling fluid to the cooling flow path (114) to cool the combustor (112) and the turbine (113), a supercritical fluid turbine (122) is driven to generate power by using a heat source absorbing heat through the supercritical fluid, and the supercritical fluid is compressed. According to the power generation system of the present invention, the supercritical fluid is allowed to flow as a cooling fluid to cool the combustor and the turbine, thereby significantly improving generation efficiency of the power generation system and preventing an environment problem by collecting and using carbon dioxide discharged as combustion gas as the supercritical fluid.
