    摘要: A casting system and method. The casting system can include an energy source and a hearth, which can have a tapered cavity. The tapered cavity can have a first end portion and a second end portion, and the tapered cavity can narrow between the first and second end portions. Further, the tapered cavity can have an inlet at the first end portion that defines an inlet capacity, and one or more outlets at the second end portion that define an outlet capacity. Where the cavity has a single outlet, the outlet capacity can be less than the inlet capacity. Where the cavity has multiple outlets, the combined outlet capacity can match the inlet capacity. Further, the cross-sectional area of the tapered cavity near the inlet can be similar to the cross-sectional area of the inlet.

    摘要: The invention provides a system for calcining active lime, including a precalcining furnace for receiving limestone materials to be calcined and precalcining the limestone materials, and a rotary kiln for receiving the materials containing precalcined product from the precalcining furnace, outputting the formed active lime, and at the same time supplying a first flue gas to the precalcining furnace. The calcining system further includes a precalcining furnace combustion device, which generates a second flue gas and supplies it to the precalcining furnace, such that the limestone materials are precalcined in the precalcining furnace under the action of the first flue gas and the second flue gas. In this way, the precalcining rate of the limestone materials in the precalcining furnace is significantly improved. Since the heat exchange in the precalcining furnace is mainly in the form of convective heat exchange having a high heat efficiency, the heat exchange efficiency of the whole system is improved, and thus the heat consumption of the system is reduced.

    摘要: 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.
