Patent number: 10047953Abstract: This gasification melting facility includes: a fluidized bed gasification furnace that generates pyrolysis gas by thermally decomposing waste and discharges incombustibles; a vertical cyclone melting furnace that includes a pyrolysis gas duct through which the pyrolysis gas is introduced; a pyrolysis gas passage that connects the fluidized bed gasification furnace with the pyrolysis gas duct of the vertical cyclone melting furnace; pulverizer that pulverize the incombustibles into pulverized incombustibles so that the particle size of the incombustibles becomes fine; and airflow transporter that puts the pulverized incombustibles in the pyrolysis gas passage, and separating metal contained in the pulverized incombustibles by a difference in specific gravity while conveying the pulverized incombustibles together with airflow. The pyrolysis gas and the pulverized incombustibles are melted in the vertical cyclone melting furnace.Type: GrantFiled: April 5, 2011Date of Patent: August 14, 2018Assignee: MITSUBISHI HEAVY INDUSTRIES ENVIRONMENTAL & CHEMICAL ENGINEERING CO., LTD.Inventors: Jun Sato, Toshimasa Shirai, Yoshihisa Saito, Norio Yoshimitsu, Yasunori Terabe
