摘要: A method and apparatus for treating wastes by two-stage gasification recovers metals or ash content in the wastes in such a state that they can be recycled, and gases containing carbon monoxide (CO) and hydrogen gas (H2) for use as synthesis gas for ammonia (NH3) or production of hydrogen gas. The wastes are gasified in a fluidized-bed reactor at a low temperature. Then, gaseous material and char produced in the fluidized-bed reactor are introduced into a high-temperature combustor, and gasified at a high temperature and ash content is converted into molten slag. After water scrubbing and a CO conversion reaction, the gas is separated into H2 and residual gas. The residual gas is then supplied to the fluidized-bed reactor as a fluidizing gas.

摘要: In an improved system for recovering heat from a combustion gas produced by burning wastes, the combustion gas or combustible gas produced by partial burning of the wastes subjected to dust filtration in a temperature range of 450-650.degree. C. at a filtration velocity of 1-5 cm/sec under a pressure of from -5 kPa (gage) to 5 MPa before heat recovery is effected. The dust filtration is preferably performed using a filter medium which may or may not support a denitration catalyst. Heat recovery is preferably effected using a steam superheater. The dust-free gas may partly or wholly be reburnt with or without an auxiliary fuel to a sufficiently high temperature to permit heat recovery. The combustion furnace may be a gasifying furnace which, in turn, may be combined with a melting furnace. If desired, the reburning to a higher temperature may be performed under pressure and the obtained hot combustion gas is supplied to a gas turbine to generate electricity, followed by introduction of the exhaust gas from the gas turbine into a steam superheater for further heat recovery. The system can raise the temperature of superheated steam to a sufficient level to enhance the efficiency of power generation without possibility of corrosion of heat transfer pipes by the combustion gas or combustible gas.

摘要: 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.
