Description of the Related Art For example, in a method of operating a plant for producing an olefinic hydrocarbon from a natural gas or a petroleum hydrocarbon by cracking hydrocarbons disclosed in European Patent Publication No. 122534, a natural gas or petroleum is used. The hydrocarbons are indirectly heated by the heat generated when the oxygen-containing combustion gas is burned in the thermal decomposition furnace that produces the olefinic hydrocarbons. The main components are an air compressor, a gas generator, and a gas turbine, and the exhaust gas from the gas turbine is supplied to a pyrolysis furnace where it is mixed with air and burned as an oxygen-containing combustion gas. On the other hand, the gas turbine drives the generator. Since the exhaust gas from the gas turbine does not have the oxygen content necessary for combustion gas in the exhaust gas, the external fresh air supplied through the air fan is supplied from the gas turbine to make up for the insufficient oxygen demand. Is added to the exhaust gas of. That is, in this case, the oxygen-containing combustion gas is a mixture gas of two components of exhaust gas from a gas turbine system including an air compressor, a gas generator, and a gas turbine, and external fresh air supplied through an air fan. It consists of

Air flap a provided in each of the pyrolysis furnaces A to F
~ F is the oxygen-containing combustion gas from the conduit 12 to the pyrolysis furnace A ~
It is set to be sent to F (air flaps a to f are flap positions shown by solid lines). When the gas turbine system or the gas turbine 7 fails, the opening / closing flap 13 is closed and at the same time, the air flaps a to f are automatically and suddenly switched, and the external fresh air is thermally decomposed through the air flaps a to f. It is supplied to A to F (air flaps a to f are flap positions shown by broken lines). At the same time, the air flap a ~
The f disconnects the conduit 12 from the pyrolysis furnaces A to F, and thus disconnects the pyrolysis furnaces A to F from the residual exhaust gas supply communication conduit from the conduit 12.
