Abstract

PURPOSE:To economize the used volume of vapor without decreasing exhausting capacity, by arranging steam ejector in parallel dividing plurally and operating selectively according to the transition of vacuum degree in the vessel. CONSTITUTION:Steam ejector in the exhaust system is divided more than two, for example, divided 4Ea and 4Eb and 5Ea and 5Eb and these are arranged in parallel, Exhausting capacity of divided ejector is distributed so as one ejector to be possessed minimum necessary exhausting capacity at the stage of highly evacuated. Hereby, degassing treatment is able to carry out, for example, by operating the ejector 4E and 5E only at the time of treating the steel for sheet in a low vacuum degree.
