GASIFICATION POWER GENERATION SYSTEM PROVIDED WITH CARBON DIOXIDE SEPARATION AND RECOVERY DEVICE

摘要

A gasification power generation system provided with a carbon dioxide separation and recovery device having a shift reactor to convert carbon monoxide in fuel gas into carbon dioxide, a carbon dioxide absorption tower producing fuel gas from which carbon dioxide has been removed, and an absorption liquid recycling device, an evaporator downstream of the shit reactor generates steam which is supplied to a steam line upstream of the shift reactor for supply thereto of a steam mixer. This steam flows from the steam mixer into the shift reactor as shift steam together with the fuel gas. The system also includes a gasification power generation system having a gas turbine device driven by burning the fuel gas from which carbon dioxide has been removed, an exhaust heat recovery boiler to generate steam, and a steam turbine driven by the steam.
