Described is an integrated process of cogasifying an engineered fuel, formulated to be suitable for working under reducing environment, with coal and cofiring another engineered fuel, formulated to be suitable for working under oxidizing environment, with coal to produce electric power.

An incinerator has a spherical chamber body to define an incineration chamber and includes a port structure with an opening that provides access to the incineration chamber. A hatch is pivotably attached to the port structure to provide access to the opening or to close the opening in the port structure. An incendiary device support member located within the incineration chamber to hold an ignitable incendiary device. A flammable panel member is located within the incineration chamber and positioned over the incendiary device support member. The panel member supports IEDs, explosive devices or biological agents for incineration. When the ignitable incendiary device is ignited, thermal energy is produced to incinerate the IEDs, explosive devices or biological agents positioned on the panel member.

Problem to be Solved To provide a waste gasification melting apparatus which, even if a fuel gas is used as an alternative to a part of the coke, the temperature of the coke bed can be sufficiently raised, and a method using the same. Solution A waste gasification melting apparatus including an oxygen rich air supply apparatus 14 for blowing oxygen rich air into a tuyere 5, and a fuel gas supply apparatus 15 for supplying a fuel gas to the tuyere 5, and a controller 16 for controlling the oxygen rich air supply apparatus 14; the oxygen rich air supply apparatus 14 mixing air and oxygen to prepare oxygen rich air and supply the oxygen rich air to the tuyere 5; and the controller 16 controlling the amount of air to be mixed and the amount of oxygen to be mixed in the oxygen rich air supply apparatus 14 so as to give an oxygen concentration of the oxygen rich air in accordance with the amount of fuel gas supplied to the tuyere 5 from the fuel gas supply apparatus 15.

A waste gasification and melting furnace that promotes the drying and pyrolytic decomposition of waste in the shaft section, making it possible to limit the conveyance of moisture and volatile components to the bottom of the blast furnace and to reduce the consumption of extra coke. The waste gasification and melting furnace includes a shaft section; a melting furnace section; and a communicating section.
