The opening-and-closing type heater comprises a base, a tube body mounted on the base and a tube body opening-and-closing mechanism; the tube body comprises a fixed tube body and a movable tube body, the fixed tube body and the movable tube body are arc-shaped shells, and form a hollow shape when the openings thereof match with each other; the tube body opening-and-closing mechanism is connected to the movable tube body for realizing the opening-and-closing of the movable tube body and the fixed tube body. The invention solves heat retaining and heating problems during the forging process of the main shaft forgings and avoids internal defects due to rapid temperature drop of the main shaft forgings.

Abstract: A method of separating foreign polymers from a polymer mixture that comprises amorphous PET particles and crystalline PET particles, wherein the softening point of the foreign polymers is lower than that of the crystalline PET particles, and wherein the method includes separating the amorphous PET particles from the polymer mixture, heating the resulting polymer mixture to a temperature between the softening point of the foreign polymers and that of the crystalline PET particles, and separating the foreign polymers from the resulting polymer mixture. Also, a device for separating foreign polymers from a polymer mixture that comprises amorphous PET particles and crystalline PET particles, the device including a first separation unit for separating the amorphous PET particles from the polymer mixture, and a second separation unit for separating the foreign polymers from the resulting polymer mixture.

Abstract: Solid carboniferous fuels contain varying quantities of moisture, mercury, chlorine, nitrogen, sulfur, heavy metals and other materials that attain vapor pressure at elevated temperatures. The cost effective removal of these degrading and sometimes hazardous materials is important to the further use of the fuel for combustion as a solid, liquid, or gas. The solid fuel is cut, shredded, ground or sieved to appropriate size, and heated in a chamber that can exclude oxygen and air thus preventing ignition. The unwanted materials are driven in the gaseous state and extracted for disposal. The solid fuel cleaned of pollutants exits the chamber and is cooled below ignition temperature prior to contact with oxygen. The solid fuel thus purified is more appropriate for combustion, liquefaction or gasification due to the reduced costs in use as a fuel or in the post combustion clean up.

Abstract: A cement product is disclosed. The cement product includes clinker defined by a feedstock material and a ladle metallurgical facility slag material derived from a ladle metallurgical facility steel production system. A system and method for manufacturing clinker is also disclosed.

Abstract: The system according to the invention for thermally processing lumpy solid material substantially comprises a preheating device, a furnace and a separation or classification device which is arranged therebetween and which has a coarse material outlet connected to the furnace and a fine material outlet. The furnace and the preheating device are connected to each other by means of a gas/solid material line which is arranged so as to be inclined relative to the vertical, the furnace exhaust gases being introduced at the end of the gas/solid material line at the furnace side and the preheated solid material being supplied at the end at the preheater side. The separation or classification device is connected to a bypass line which branches off from the gas/solid material line so that at least a partial amount of the preheated solid material can be branched off via the bypass line by means of gravitational force and can be supplied to the separation or classification device.

Abstract: A method of cooling a substance heat treated in a material processing plant in which the substance is cooled in a cooling apparatus to a temperature that is about 25% to about 55% of the temperature at which the partially cooled substance was when it entered the cooling apparatus. Heated gas is recycled from the cooling apparatus to at least one other process within the plant and the partially cooled substance is delivered from the cooler to a cogeneration system in which the substance is further cooled and the heat removed from the substance is used to generate power.

Abstract: An object of the invention is to provide a substrate treatment device that can lengthen the maintenance cycle, and prevent any by-product from falling on substrates even if it is accumulated, and a manufacturing method of such a substrate treatment device, and an embodiment of the invention is directed, comprising: a treatment chamber that subjects a substrate to a treatment while keeping hold of it by a substrate retention member; a reaction tube that configures the treatment chamber; a heating device that is disposed around the reaction tube for heating the treatment chamber; and an exhaust tube that is linked to the reaction tube on an upper side than the substrate inside of the treatment chamber and is extended downward from the heating device, and exhausts a gas inside of the reaction tube in which an extension portion as a result of the extension is disposed away from the reaction tube.

Abstract: A method and apparatus for using in rotary kilns having a calciner and a tertiary air duct, which uses the hot air from the tertiary air duct for burning waste material in a combustion chamber formed therein, achieving a complete combustion of the waste material and discharging the hot combustion gas to the tertiary air duct for its use as supplemental energy source by the rotary kiln.

Abstract: A pre-screening element for use with pneumatic discharge systems for transport of powdered material has a housing having an inlet and an outlet, a first vane array, having a plurality of strip-shaped first vanes arranged inside the housing and spaced apart with respect to a longitudinal axis of the housing, each individual vane of the plurality of first vanes being substantially parallel to other vanes of the first vane array and having a long edge facing the inlet, and a second vane array, having a plurality of strip-shaped second vanes arranged inside the housing each individual vane of the plurality of second vanes being substantially parallel to other vanes of the second vane array and having a long edge facing the inlet, a longitudinal axis of the first vanes being arranged at an angle to a longitudinal axis of the second vanes.

Abstract: The invention relates to a charging device for creating superimposed layers of fine-grained bulk material on a rotating hearth (2). For each layer of bulk material to be charged, said charging device comprises a discharge hopper (22) having an outflow slot (36) and a discharge roller (42) positioned ahead of each outflow slot (26). Said outflow slot (36) and discharge roller (42) extend essentially at a right angle to the direction of rotation of the rotating hearth and the discharge roller (42) has a drive (44), the rotational frequency of which can be controlled.

Abstract: A rotary kiln for treating material (e.g., for burning lime). The kiln includes a rotatable, hollow body for receiving material such as wet lime mud (i.e., limestone). The body has an opened end to allow the material to exit the body after it has been treated.A shroud is provided to cover the opened end of the body. The shroud includes a grate for allowing particles of the material of a certain maximum size to pass therethrough and includes a chute for allowing particles of the material of a size greater than the maximum size capable of passing through the grate to pass therethrough. A pair of outwardly extending arm members are fixedly attached to the opened end of the body for rotation therewith and for moving any particles of the material of a size greater than the maximum size capable of passing through the grate to the chute of the shroud for passage therethrough.
