PURPOSE:To attempt marked improvement of the energy efficiency by the high-temperature exhaust gas, by connecting, to the burning air feed system of pyrolysis furnace(s), the discharge opening(s) of a variable air flow blower and the exhaust vent(s) of a gas turbine. CONSTITUTION:The discharge opening(s) of a variable air flow blower 51 and the exhaust vent(s) of a gas turbine 61 are connected to the burning air feed system of a pyrolysis furnace 10 for olefin production, an air flow from the blower 51 and/or a divergence of the input guide valve 62 (or the driving source) of the gas turbine 61 being controlled through an air flow controller 30 so that the air flow in the air duct 40 for the pyrolysis furnace 10 is equalized with that which is calculated from a fuel consumption in said furnace and also corrected with an excess oxygen content in the furnace. |
