Abstract
A gasification unit provided with a gasification furnaceto produce fuel gas production is provided. A combined power generation unitwhich generates power by rotating a gas turbine and a steam turbine using fuel gas produced in the gasification unit is provided. The combined power generation unitis made operable while fuel change over between fuel gas and an auxiliary fuel as the fuel. A control system is provided in which the degree of opening of a control valvefor a flare stackprovided in a fuel gas feed line is controlled depending upon the pressure of the fuel gas from the gasification unit when fuel change over from the fuel gas to the auxiliary fuel so as to allow the fuel gas supplied to the combined power generation unitto gradually flare from a flare stackuntil a flared status that total amount of the fuel gas is reached.
