GASIFICATION COMBINED POWER GENERATION SYSTEM USING BY- PRODUCT GAS

摘要

PROBLEM TO BE SOLVED: To provide a gasification combined power generation system using by-product gas, capable of operating the system by constant output even if the by-product gas is fluctuated, in a system for combined power generation by using the by-product gas from a blast furnace. SOLUTION: A gas turbine 13 and a steam turbine 15 are driven by making use of by-product gas from a blast furnace 10, methanol is synthesized by using gasified gas generated in the other gasification furnace 20, and the methanol is supplied to the gas turbine 13 according to the fluctuation of the by-product gas.
