    摘要: The invention relates to a method for producing quick lime from lime stone in a continuous regenerative shaft kiln, characterized in that, starting with standard conditions of excessive combustion air for the operation of this kiln, it especially includes a step where the excessive combustion air is progressively reduced until a content greater than 1000 ppm (in volume) of carbon monoxide is reached in the connection flue between the tanks. An increase in the content of gaseous sulphur dioxide is then observed in the gas flue, with respect to a kiln operated in standard conditions.

    摘要: The present invention relates generally to a method and system for the supply of a continuous stream of hot direct reduced iron (HDRI) from a direct reduction (DR) shaft furnace or direct reduced iron (DRI) reheating furnace to a point outside of the DR shaft furnace or DRI reheating furnace where the HDRI stream is split into at least two HDRI streams. The first HDRI stream is sent continuously to a hot briquetting plant by gravity in a closed duct system. The second HDRI stream is sent continuously to an adjacent melting furnace also by gravity in a closed duct system, with a surge bin and feeders, or by a combination of gravity in a closed duct system, also with a surge bin and feeders, and a generally horizontal charge conveyor. Optionally, a third HDRI stream is employed to continuously feed multiple hot transport vessels.

    摘要: A method for burning lumpy combustion material, in particular limestone, dolomite and magnesite, in a regenerative shaft furnace comprising at least two shafts (1, 2) comprised of a preheating zone (A) as well as a combustion zone (B). The shafts are connected below a cooling zone (C) by a transfer channel (3). The combustion air is charged at the head of one shaft (1), heated by hot combustion material as it flows through the preheating zone (A), and brought into contact with fuel before it enters the combustion zone (B). The combustion zone (B) is flowed through by combustion gas produced in the combustion of the fuel. Cooling air is admitted at the lower end of the shaft (1) and, as it flows through the cooling zone (C), heated by hot combustion material exiting from the combustion zone. According to the invention, the combustion air heated in the preheating zone (A) and at least one partial stream of the cooling air heated in the cooling zone (C), are extracted from the shaft (1) and supplied with fuel to a combustion chamber (11), in which the combustion gas for the combustion zone (B) is produced. Furthermore, the object of the invention is also a regenerative shaft furnace for carrying out the method.

    摘要: In a double-incline shaft kiln in which ore materials are charged into the furnace from the top of a vertical external portion of the shaft and are calcined by burners installed in the lower portion of the shaft, the calcining zone is effectively extended by the provision of an injector which causes the hot gas to flow in the lower portion of the shaft parallel to the flow of ore materials. Further, at the turnover locations for the ore descending through the shaft, the width of the shaft is broken into at least two portions which promotes a more even velocity of the material flow across the width of the shaft so as to enable combustion control and the prevention of the ash of solid fuel, such as coal, from mixing with the calcined material to cause discoloration and lumps.

    摘要: In vertical continuous furnace calcining of lime, dolomite, magnesite, or the like, part of the air which is introduced at the lower end of the furnace chamber is drawn off in the area of the cooling zone within the chamber and is then reintroduced in encompassing relation into the material column in the firing zone within the furnace chamber and which is located immediately above the cooling zone, the remainder of the air flowing up through the column of material being treated in the chamber. Cleaning of the withdrawn cooling air and addition of fresh air are provided for.

    摘要: Uniform heat treatment of particulate material of a nonuniform gradation in a vertical kiln or retort is effected by regulating either the flow of particulate material from the outlet of the kiln or the heat input to the kiln in response to differential pressure changes between fluid, such as combustion-supporting fluid and process gas flowing into and from the burning or calcining zone, to result in a balance between particulate mass flow and heat input, and a substantially uniformly heat-treated product.
