About 70% of the gas increased in pressure is fed on an acidic gas removing device 7 where CO2, H2S, etc. are removed from the gas. The gas increased in the reduction power is heated up to the required temp. by a gas heater 8 and enters a piping 21 from which the gas is joined with the reducing gas generated in the generator 4 and is blown through a main reducing gas inlet 10 into the furnace 1. About 30% of the gas increased in pressure is heated by the heater 8 and is made into the preliminary reducing gas which is blown through a preliminary reducing gas inlet 9 into the furnace 1.

摘要： PURPOSE:To improve gas removing ability by continuously measuring a gas flow rate permeating through a gas separation membrane module and reversely passing a heated gas flow when the gas flow rate is decreased below the set value to remove stuck contaminant. CONSTITUTION:A gaseous starting mixture is, after pressurized, introduced into a valve 12 and is charged into a hollow yarn module 1 from a gaseous mixture inlet 7. A permeable component is passed through the hollow yarn membrane and is taken out from an outlet 9 through a drum side chamber 3. At that time, the permeating gas flow rate is measured with a gas detector 19 and when the measured value is below the previously set value, the valve 12 is closed and a valve 13 is opened by a control system. Then the gaseous mixture is heated by a heater 14 and flows into the hollow yarn membrane module form a gaseous mixture reverse flow inlet 8 to remove components stuck to the hollow yarn membrane. In this way, the gas separation performance of the hollow yarn is improved.
