    摘要： Cement-forming raw materials are introduced into a swirling stream of hot gas in a cylindrical reaction zone where the raw materials react to form clinkers and where the gas stream holds the clinker particles in suspension until the particles grow heavy enough to drop to the lower portion of the reaction zone. Apparatus suitable for carrying out the process is also described.

    摘要： Tricalcium silicate materials useful in the production of Portland and other cements are prepared by melting a mixture of materials comprising basically line and silica in an electric furnace. The voltage between the electrodes and the conductivity of the melt are controlled so that a predetermined separation will be maintained between the lower end of the carbon electrode and the melt.

    摘要： A method of calcining a raw material to obtain a cementitious material, includes providing a flow of raw material containing a metal carbonate, such as CaCO3 to a calcination system, introducing the flow of raw material into a first thermal reactor and at least partially decarbonating the raw material in the first thermal reactor by subjecting the raw material to a first heat treatment at a first temperature of at least 650° C. in order to obtain an at least partly decarbonated material and CO2, wherein the first thermal reactor is heated by electrical energy, and obtaining the cementitious material as a result of the first heat treatment.

    摘要： An apparatus for recycling fly ash has a quantum energy generator therein. The apparatus recycles fly ash generated as the combustion waste from the burning of coal in thermal power plants, into construction materials such as cement substitutes, environment-friendly cover materials, etc. Unburned pulverized coal is removed while generating carbon monoxide (CO) or carbon dioxide (CO2) through a combustion reaction, in which the unburned pulverized coal of the fly ash contacts the thermal electrons discharged during a thermal decomposition process at a high temperature, the negative electrodes of the thermal decomposition part, which are heated at a high temperature of 500° C., which is an ignition point of the unburned pulverized coal, or higher, and a high-voltage discharge electrode of an electrochemical reaction part, then heated at 500° C. or higher, and then naturally burned under an oxygen atmosphere (oxygen or ionized oxygen ions in air contained in the fly ash).

    摘要： A process and apparatus for producing hydraulic cements such as portland cement utilizing electrical energy as the heat source is described. The electrical heat source includes a plasma arc torch operating in the transferred mode. A feature of the apparatus and process is in utilizing a liner within the furnace composed of a material having substantially the same chemical composition of the cement that is to be produced in the furnace. Preferably the feed materials properly proportioned to have the desired constituency of cement are fed below the melt of the furnace. The process is compact and efficient relative to the conventional rotary kiln used for producing cement.
