Abstract: The yield of cement clinker recovered from a kiln assembly is enhanced by feeding a particulate material comprising silica and an oxide of at least one of calcium and aluminum, for example, fly ash into contact with hot cement clinker; the fly ash melts to a partially fused material which chemically reacts with the hot clinker to produce a pyroprocessed cement clinker of crystalline hydraulic silicates; the extruder is added to the hot cement clinker downstream of the formation of the cement clinker, and suitably is added to the hot cement clinker at the upstream end of the cooler of the kiln assembly, or within the kiln, downstream of the burning zone, and more especially in the initial cooling zone at the discharge end of the kiln.

Abstract: Coal ash, which also consists of fly ash, is a very fine granular solid residue obtained as a by-product of coal combustion. The invention relates to the surprising result that a fuel can be obtained from coal ash. The process involves a pneumatic separation of the coal ash at relatively low temperatures. The coal ash is separated into at least two size fractions. The size fractions obtained by the process of this invention include at least one with lower carbon and another containing increased levels of carbon in the range of 50% by weight and a heating value in the range of 4000 to 6000 Btu/lb.

Abstract: 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.
