Abstract: The present invention relates to a waste carbonization method which produces charcoal and/or activated carbon from solid wastes, such as wood waste, and renders produced gas completely harmless. Solid wastes B are exposed to gas generated in pyrolysis gasification of other wastes A in a gasification furnace 1 to produce charcoal and/or activated carbon from the solid wastes B.

Abstract: Exhaust gas is generated when various waste products are combusted. The generated exhaust gas is introduced into a heat exchanger to heat an intermediate gas such as air by heat exchange. The heated intermediate gas is then used to heat superheated steam, which is then supplied to a steam turbine coupled to a generator.

Abstract: A pressurized internal circulating fluidized-bed boiler is incorporated in a combined-cycle electric generating system in which a fuel such as coal, petro coke or the like is combusted in a pressurized fluidized bed and an exhaust gas produced by the combusted fuel is introduced into a gas turbine. The pressurized internal circulating fluidized-bed boiler includes a pressure vessel, a combustor disposed in the pressure vessel and a primary fluidized bed incinerating chamber provided with an air diffusion device. A thermal energy recovery chamber is partitioned from the primary fluidized bed incinerating chamber by an inclined partition wall. A fluidizing medium flows into and out of the primary incinerating chamber and the thermal energy recovery chamber.

Abstract: A fluidized bed water tube boiler comprising a fluidized bed combustion section including a fluidized bed formed from a continuous water tube wall, a free-board section for burning volatile components produced in the fluidized bed combustion section, and a convective heat transfer section comprised of a steam drum and a water drum connected to the downstream side of the freeboard section through water tubes for recovering heat from combustion exhaust gas; wherein the fluidized bed combustion section and the freeboard section are formed as separable modules which are connected to each other, and circulation of a boiler water between the fluidized bed combustion section and the convective heat transfer section is separated from that between the freeboard section and the convective heat transfer section.

Abstract: An internal recycling type fluidized bed boiler in which a fluidized bed portion of the boiler is divided by a partition into a primary combustion chamber and a thermal energy recovery chamber, at least two kinds of air supply chambers are provided below the primary combustion chamber, one for imparting a high fluidizing speed to a fluidizing medium and the other for imparting a low fluidizing speed thereto, thereby providing a whirling and circulating flow to the fluidizing medium in the primary combustion chamber. The fluidizing medium is moved downward in a moving bed in the thermal energy recovery chamber.

Abstract: An internal recycling type fluidized bed boiler includes a primary fluidized bed incinerating chamber constructed by an air diffusion plate, and an inclined partition wall provided above a portion of the diffusion plate where the mass flow of the air injected from the diffusion plate is greater than that from another portion so as to interfere with the upward flow of the fluidizing air injected from that portion and deflect it towards the portion above the diffusion plate where the mass flow of gas injected is smaller. A thermal energy recovery chamber is formed between the inclined partition wall and a side wall of an incinerator. The inclined partition wall is inclined by 10.degree.-60.degree. relative to the horizontal and is arranged such that the length of its projection in the horizontal direction is 1/6-1/2 of the horizontal length of the bottom of the incinerator bottom.

Abstract: A combustion apparatus has a combustion furnace section, a free board section which is downstream of the combustion furnace section, and a post-combustion chamber which is downstream of the free board section, the post-combustion chamber being disposed at a position offset from the position directly above the free board section, wherein the apparatus is characterized in that a gas blowing structure is provided in the vicinity of the boundary between the free board section and the post-combustion chamber, the gas blowing structure having a plurality of pipes disposed parallel to each other at a predetermined spacing, each pipe being provided with a gas outlet hole for blowing a gas, for example, air, counter to the combustion gas flowing toward a discharge port.

Abstract: A method of and apparatus for dewatering a substance which is to be dewatered such as sludge wherein the substance to be dewatered is pressed between a pair of rollers (11, 212) or plate-shaped press members (331) each having its press surface formed from a rigid porous material (6, C, 331) having water absorption and retention properties based on the capillary action; water squeezed from the substance by pressing is permeated into the rigid porous material due to water absorption based on the capillary action or water pressure and the permeated water is retained by virtue of the water retention properties based on the capillary action, thereby dewatering the substance; and the water retained by the rigid porous material is discharged by sending pressurized air to regenerate the capillary tubes.

Abstract: A method for incinerating material is disclosed wherein a vertical thermal reactor of the fluidized bed type is employed, the reactor being generally a rectangular shape in a horizontal section and having opposed side walls. Fluidizing medium is subjected to different mass flow at the center portion and the side portions so that relatively strong side fluidized beds are formed adjacent the side walls and a relatively weak fluidized bed is formed at the center sandwiched by the side fluidized beds free of any obstructions therebetween. The center fluidized bed tends to descend relative to the side fluidized beds which are deflected at the upper portions thereof, respectively toward the center so that the fluidized medium circulates from the lower part of the center fluidized bed to the lower parts of the side fluidized beds and from the upper parts of the side fluidized beds towards the upper part of the center fluidized bed.

The reactor is provided with a unique feeder for charging the material so that the incombustible items the size of which is not suitable to be charged into the furnace are rejected by reversing the feeding direction of the feeder when the presence of such items is sensed.
