The present invention relates to a combustion generation apparatus which generates power using organic materials. According to one embodiment of the present invention, the combustion generation apparatus includes a fuel supply unit which includes a plurality of single fuel suppliers configured to supply different organic raw materials, a fuel mixer configured to mix the organic raw materials supplied by the single fuel suppliers, and a mixed fuel supplier configured to receive the organic raw materials uniformly mixed in the fuel mixer, a reaction unit which includes a combustion chamber configured to burn the organic raw materials supplied by the mixed fuel supplier, and a generation unit which includes an internal generator configured to generate power using heat energy generated by a combustion reaction of the organic materials in the combustion chamber and an external generator configured to generate power using heat energy released outward from the combustion chamber.

A pellet stove includes a hopper for storing pellets, a basket for receiving the pellets by gravity, a duct for conveying combustion air to the basket, and a conduit for conducting heated air away from the basket. The position of the basket is adjustable, such as by raising and lowering it, or by rotating it, so as to control the number of pellets in the area of most intense combustion. One or more burn plates, positioned below the basket, provide platforms on which pellets falling through the basket can burn down to a smaller size. The pellet stove requires no external source of power. The stove so constructed enables quiet, efficient and clean burning of the pellets.

A circulating fluidized bed boiler is described, comprising a furnace, a loopseal, and a loopseal heat exchanger arranged in the loopseal. The loopseal heat exchanger comprises walls limiting an interior of the loopseal heat exchanger, a first particle outlet for letting out particulate material from the loopseal heat exchanger, an inlet for receiving bed material, heat exchanger tubes arranged in the interior of the loopseal heat exchanger, and a first ash removal channel configured to let out ash from the loopseal heat exchanger. An ash cooler is configured to receive ash from the first ash removal channel. In the loopseal heat exchanger the first ash removal channel is arranged at a lower level than the first particle outlet.

A cooking apparatus, having a body defining an interior cooking chamber for cooking food, a pellet supply portion coupled to the body and including a hopper for storing fuel, a combustion chamber for burning the fuel and heating the cooking chamber, a feeding mechanism for supplying fuel from the hopper to the combustion chamber, and a removable collection receptacle located below the combustion chamber. The apparatus also includes an ash-shaker located between the collection receptacle and the combustion chamber, the ash-shaker including an external actuator that controls one or more moving elements located in the combustion chamber, wherein movement of the moving elements encourages unburned debris in the combustion chamber to fall into the receptacle, after which the collection receptacle can be removed and the unburned debris discarded.

A mobile trash incineration apparatus that can receive a large amount of trash while fully containing the incineration process. In particular, the apparatus can include a container or housing having one or more support bars located at the lower region of the container, and a meshed screen supported by the one or more support bars. Further, the container can include a first door and second door secured to the one or more support bars, wherein the first and second door are pivotable about an axis. In addition, a first latch can be secured to the first door, and a second latch secured to the second door, wherein the first door and second door can be configured to release debris or ashes from the container after an incineration process.

A method for processing ash from waste incineration plants by wet classification includes mixing the ash with a liquid in a mixing hopper. After screening, the mixture is fed to a first classifying stage, including an upflow classifier and an upstream hydrocyclone, where it is separated into a good fraction and a residual fraction. The residual fraction is drawn off as a suspension on an upper side of a fluidized bed of the upflow classifier. The good fraction is drawn off on an underside of the fluidized bed. A pass through fraction is fed back into the hydrocyclone installation and a material flow containing particles which are smaller than a separation particle size is separated as cyclone overflow. The cyclone overflow is separated in a second classifying stage into a fine particle mineral fraction and a residue which has a grain size upper limit between 20 m and 50 m.
