  • Method for starting up pressurized fluidized bed incinerator system
    Patent number: 10006631
    Abstract: Is provided a method for starting up a pressurized fluidized bed incinerator system by which cracking of silica sand as a bed material can be prevented at low costs. By heating the silica sand as the bed material filled up in a bottom portion of a pressurized fluidized bed incinerator, a temperature of a freeboard of the incinerator is heated, and after the temperature of the freeboard is heated to 750 to 900° C., a material to be treated having a water-containing organic substance is fed to the pressurized fluidized bed incinerator.
    Type: Grant
    Filed: March 22, 2013
    Date of Patent: June 26, 2018
    Assignees: TSUKISHIMA KIKAI CO., LTD., SANKI ENGINEERING CO., LTD.

  • Method for conveying impurities in pressurized fluidized bed incinerator system
    Patent number: 10001277
    Abstract: A method for efficiently conveying impurities in a pressurized fluidized incinerator system is provided. Cleaning gas is supplied to an upper valve, and thereafter, the upper valve is driven so as to communicate an upper discharge device and a tank. The upper discharge device is driven so as to convey the impurities from the dust collector to the tank, and thereafter, the upper discharge device is stopped and the upper valve is driven so as not to communicate the upper discharge device and the tank. Thereafter, the supply of the cleaning gas to the upper valve is stopped.
