  • Patent number: 11725155
    Abstract: An organic material gasification system is configured such that a carbonization furnace provided with a first air supply mechanism that radiates high-temperature combustion air and high-temperature steam to an organic material combustion region and with a second air supply mechanism that supplies combustion air to an exhaust gas combustion region, to discharge high-temperature exhaust gas is connected to a gasification furnace including a heating unit penetrating through a reactor. A carbide from the carbonization furnace is supplied to the reactor, and the high-temperature exhaust gas from the carbonization furnace is supplied to the heating unit, so that the carbonization efficiency and the carbonization quality are improved and the gasification efficiency is improved.
    Type: Grant

  • Patent number: 8835707
    Abstract: An asbestos detoxification method comprising a step B1 of impregnating an existing asbestos layer with an asbestos melting agent and detaching the existing asbestos layer; a step B2 of pulverizing the existing asbestos layer; a step B3 of loading the pulverized material obtained in step B2 into a melting furnace; a step B4 of heating a resin subsidiary material used in the disposal of the asbestos layer to vaporize the resin portion thereof and further converting the vaporized resin portion into plastic oil; a step B5 of combusting either or both of the plastic oil obtained in step B4 and a fuel; and a step B6 of heating and melting the pulverized material that is in the melting furnace with the use of the heat obtained in step B5.
