Dcfc-igfc hybrid power generation system

The present invention relates to a DCFC-IGFC hybrid power generation system using a direct carbon fuel cell and a solid oxide fuel cell, and more particularly, to a non-ashless coal production reactor that generates raw ash coal by supplying raw coal and a solvent; An ashless coal supply line for directly supplying the non-ashless coal to the carbon fuel cell from the ashless coal producing reactor; A direct carbon fuel cell supplying the non-ashless coal to the fuel electrode to generate electric energy; A pressurizing line for pressurizing the CO 2 -containing gas discharged from the fuel electrode of the direct carbon fuel cell and supplying it to the air flow transporting and supplying device; A coal supply line connected to a lower portion of the ashless coal production reactor to supply the residual coal generated from the ashless coal to the air flow transporting and supplying device; An air flow transporting device for air streaming the coal residues supplied from the coal residual gas supply line to a gas containing CO 2 supplied through the pressurization line and supplying the coal to the gasifier; A gasifier that receives coal from the air flow transporting device and generates a synthesis gas; And a solid oxide fuel cell that receives the generated syngas to generate electric energy.
