A rotary grate with slit-shaped openings is used in fixed-bed gasifier that produces a product gas from biomass particles. The rotary grate supports the biomass particles. Each slit-shaped opening has a cross-section that conically widens in the direction from the upper to lower side of the grate. The slit-shaped openings act as planes to break up ash supported by the grate as a drive shaft rotates the grate. As the grate rotates, a dome-shaped covering in the middle of the grate causes ash to be spun laterally away from the middle and into the region of the grate where the slit-shaped openings are located. The slit-shaped openings extend concentrically around the middle of the grate. The combined open area of the slit-shaped openings on the upper side of the grate makes up between 20% to 40% of the grating surface area outside the dome-shaped covering on the upper side.

One of Japan's current environmental problems is the fact that approximately 70% of the world's incinerators for waste disposal are Japanese incinerators. Although problems such as PPM are now being addressed, discharge at the particulate level into the atmosphere still occurs. In addition, harmful substances including residual chlorine remain in residual ash, and there is a limit to the disposal of waste soil by burying. Furthermore, the costs for maintaining the energy required for incineration are enormous. The present invention is capable of solving all of the aforementioned problems, as well as reducing said maintenance costs, and effectively using unwanted substances currently considered waste by recovering, recycling, and regenerating the same. 1. A superheated steam resource recovery/recycling facility for recycling resource waste in decomposition/separation/regeneration routes , the facility comprising: a decomposition route , wherein the resource waste is housed in a heat-resistant container , an injection pipe is inserted into a steam injection port provided in the container (while a stirring rod built in the container is rotated) , the temperature therein is increased to a boiling point of 100° C. using steam , heating is further carried out to 100° C. to 400° C. using a second injection pipe to increase the temperature inside the container , the steam of vaporized gas and an extract (emulsified mixture of water/oil) which is generated at the heating stage is removed from an exhaust pipe and further heated to 400° C. to 700° C. to increase the temperature inside the container , after which ultrasonic vibration mist is injected to decrease the temperature inside the container to 50° C.; a separation route , wherein a discharging hatch at the bottom of the container is opened to move the resources of recovery waste to a separation route container; and a regeneration route for recycling the resources.2.

A waste incinerator, in a vertical structure and including from the top down: a drying section, a destructive distillation section, a reduction section, and a combustion section. The combustion section includes: two layers of grate bars, a first combustion layer, a second combustion layer, and a third combustion layer. The heat produced from the combustion in the combustion section is used to heat the carbide in the reduction section. The heated carbide reduces CO 2 produced in the combustion into CO (coal gas). The coal gas ascends to the destructive distillation section through the ambient coal gas chamber to heat and destructively distillate the waste to produce the pyrogenic coal gas and the carbide. The carbide drops to the combustion section for combustion, and the pyrogenic coal gas and the coal gas are collected by the draft fan.
