摘要： Heat is recovered from the hot solids discharged from the combustion chamber of a fluidized bed reactor. Hot solid particles as a result of combustion are removed either in the form of ash, or particles separated from a gas stream, and are passed into indirect heat exchange relationship with water, producing hot water. The hot water is mixed with fuel or other solid material to simultaneously heat and moisten the solid material (e.g. to a moisture content of 15-50%). The heated and moistened solid material is then fed into the combustion chamber, along with fluidizing air, to establish a fluidized bed in which combustion takes place. The heat exchange may take place in a closed heat exchange vessel, and the cooled solid particles may be discharged from the vessel through a pressure reduction valve.

摘要： A system for converting a coal slurry flowable through a pipeline to a coal water mixture capable of being rendered suitable for direct combustion in a boiler. The system includes a pipeline extending from a region adjacent to a mine or source of coal to a region adjacent to a boiler or furnace at which combustion is to take place. In the furnace region, the slurry from the pipeline is directed into a holding space, such as a pond, from which it is directed to a grinding apparatus. On the way to the grinding apparatus from the pond, a side stream of the slurry is directed through a dewatering apparatus where the concentration of the side stream is increased from 50-55 weight percent of solids to about 70-80 weight percent of solids. The outlet of the dewatering apparatus is directed back to the main flow of slurry from the pond, and the main flow enters the grinding apparatus where the slurry is ground to a particle size suitable for combustion, such as 70-80% weight percent of solids at -200 mesh. The ground slurry can then be directed into a small agitated tank and from this tank it can be directed into the boiler or furnace for combustion.

摘要： A process and apparatus for micronizing solid carbonaceous material and preparing carbon oil mixtures. Micronization is accomplished by projecting particles of a carbonaceous material into the point where a number of fluid streams intersect and by then impacting the particles against a rotating cone. The resulting micronized particles are then separated from the fluid in which they are entrained and are mixed with fuel oil. A preferred fluid for use in this process is a gaseous mixture consisting of about fifty percent steam and fifty percent flue gas.

摘要： Pulverized coal is slurried with water then oil or if desired oil and pulverized alkalis preferably lime or limestone is added and the mixture subjected to sonic vibrations with an energy density of at least 11.625 watts per cm.sup.2. Liquid suspension is produced and any excess water or oil separates out as a separate phase. Normally excess oil is used and the excess oil phase can be recycled. The resulting dispersion is utilized and burned in a furnace. A clean flame is produced which has the characteristics of an oil flame and not a powdered coal flame. The addition of lime is optional as its purpose is to reduce sulfur dioxide in burning where the coal contains sulfur. If there is no sulfur or so little as to meet environmental standards the addition of lime may be omitted. The amount of lime is preferably at least about twice stoichiometric based on the sulfur content of the coal. Up to 80% of sulfur dioxide produced on burning can react with the lime and the calcium sulfate produced removed by conventional particle separators.

摘要： The present invention relates to a self-powered time sharing reaction system and method for organic materials pyrolysis and combustion. The system comprises a time sharing reactor for pyrolysis and combustion, a feeder, a recovery apparatus for pyrolysis volatility products and a flue gas purifier. The whole process mainly consists of two time sharing stages of pyrolysis and combustion: organic materials are sent into the time sharing reactor for pyrolysis and combustion, and solid thermal carrier rapidly heats the organic materials and the pyrolysis reaction takes place. The produced pyrolysis volatility products enter the recovery apparatus for the recycling of the pyrolysis gas and pyrolysis oil; when the pyrolysis reaction is over, fill air into the time sharing reactor for pyrolysis and combustion to combust with the rest of the pyrolysis volatility products and the pyrolysis residue in the reactor. The heat produced during the combustion heats the solid thermal carrier, the flue gas is released after being purified, the heated solid thermal carrier is left in the time sharing reactor for pyrolysis and combustion to provide energy for the next organic materials pyrolysis. The process is thus repeated. The system has the advantages of cascade utilization of energy, short time of pyrolysis reaction and high efficiency of heat transfer.

摘要： A process for disposing of sewage sludge by heating and shearing an aqueous mixture of sewage sludge in a tubular-shaped processing means containing a plurality of rotating agitators to produce a pumpable aqueous slurry of sewage sludge. The aqueous slurry of sewage sludge is mixed with solid carbonaceous fuel or an aqueous slurry of solid carbonaceous fuel to produce a pumpable aqueous slurry of sewage sludge and solid carbonaceous fuel. The aqueous slurry of sewage sludge and solid carbonaceous fuel is heated in a first steam jacketed rotary disc mixing-heating means. Alternately, first and second hoppers are filled with said heated aqueous slurry of sewage sludge and solid carbonaceous fuel and cycled between a second steam jacketed rotary disc mixing-heating means; wherein while one hopper is being filled the contents in the other hopper are being dewatered. The thickened pumpable slurry is burned in a partial oxidation gasifier, furnace, boiler, or incinerator to produce a hot effluent gas steam. By this process, noxious sewage sludge may be disposed of without contaminating the environment. By-product synthesis gas, reducing gas, or fuel gas may be produced.

摘要： A method and apparatus for producing a coal/water mixture for combustion in a fluidized bed unit. To produce a hydraulically transportable coal/water mixture, crushed raw coal is preliminarily mixed with water in a first stage. This mixture is final mixed in a second mixing stage. The fine grain-size fraction required for the hydraulic transport is generated in the first mixing stage. The viscosity of the mixture present in the second mixing stage is determined, and as a function thereof additional water is added to the mixture in the second mixing stage, and/or the mixing process in the first mixing stage is altered in order to alter the fine grain-size fraction.
