| 182 | USE OF HIGH CARBON COAL ASH | EP03700759.8 | 2003-01-28 | EP1478603A1 | 2004-11-24 | OATES, David Bridson; WHELLOCK, John, Graham; ZACARIAS, Philip, Souza |
| A synthetic slag is produced by a high temperature combustion reaction between coal ash having a high carbon content, and a source of lime such as cement kiln dust. The carbon content of the coal ash is oxidized by oxygen gas, which typically is derived from air or an air/oxygen combination in an exothermic reaction and the heat generated is exploited in the melting process. In this way the gaseous products will typically comprise nitrogen, unreacted oxygen and carbon dioxide, and heat energy can be readily recovered from the hot off gas products evolving during the combustion reaction. The synthetic slag may be pelletized and employed as lightweight mineral aggregate or milled to cement fineness to provide slag cement. | ||||||
| 183 | METHOD AND APPARATUS FOR INCINERATION OF COMBUSTIBLE WASTE DURING THE MANUFACTURE OF CEMENT CLINKER | EP00956376.8 | 2000-07-21 | EP1200778A1 | 2002-05-02 | HELM, Alexander |
| A method for incineration of combustible waste during the manufacture of cement clinker where cement raw meal is preheated and calcined in a preheater (1) with a calciner (3), burned into clinker in a kiln (5) and cooled in a subsequent clinker cooler (7), in which method the waste is incinerated in a separate compartment (9) subject to simultaneous supply of hot air, the exhaust gases produced during the waste incineration process being vented to the preheater for heating the cement raw meal, and the slag generated during the waste incineration process being extracted from the compartment. The method is peculiar that the waste is introduced via a waste inlet (11) onto a supporting surface (21) incorporated in the compartment (9) and in that, during incineration, the waste is transported through the compartment to the outlet (23) of the compartment along a circular path. | ||||||

| The invention concerns a method of producing pig iron, non-ferrous metal alloys, ferrochromium carbides or carbon-free ferrochromium and synthetic blast furnace slag using residues of incinerated waste or slag containing metal oxides. According to the invention the materials used in waste-incineration, such as for example light fractions obtained from vehicle shredders and blast furnace dusts, are (1) oxidized at least partially and then reduced, with the deposition of nonferrous metals or alloys. The oxidic slag phase, depleted of metals or alloys, is then (3) mixed with liquid steelworks slag, optionally with the further addition of blast furnace dusts, whereupon, as the viscosity of the steelworks slag is reduced, raw steel is extracted, and (4) the remaining slag portion is subjected to further reduction, producing pig iron and possibly ferrochromium alloys. The resultant synthetic blast furnace slag is then discharged. | ||||||
