Abstract: A system for energy optimization in a plant (3) for producing direct-reduced metal ores (3). The plant (3) has at least one reduction unit (12), a device for separating gas mixtures (7, 7a, 7b) having an associated compressing device (4, 4a, 4b), and a gas-heating device (10) upstream of the reduction unit (12). Part of the process gases (2, 2a, 2b) is fed by a feed line from a smelting reduction plant to the plant for producing direct-reduced metal ores (3). A turbine (8, 8a, 8b) is fit between the device for separating gas mixtures (7, 7a, 7b) and the gas-heating device (10) upstream of the reduction unit (12) such that a pressure drop between the device for separating gas mixtures (7, 7a, 7b) and the reduction unit (12) is converted into forms of energy that can be used to operate additional components (4, 4a, 4b, 15, 15a, 15b) of the plant (3), in particular electrical energy and/or mechanical energy. Energy consumption of the plant (3) is reduced.

Abstract: To distribute charging material evenly in an enclosure such as a furnace or reactor to ensure its best operation, a charging material distribution inside the enclosure 30 of the furnace is used. It has a movable charging device 4 in the form of a spout through which the charging material is fed into the enclosure. The distribution device is small in size and light in weight. It has a moveable charging device 4 in the form of a spout which is suspended on a gimbal suspension 2 on a fixed charging device, which is in the form of a chute 3 inside the enclosure.

Abstract: A cooling plate with reinforcing part for furnaces which are provided with a refractory lining. Coolant passages are arranged in the interior of the plate, which is provided with at least one additional cooling segment provided with a cooling passage into which a displacement body is inserted.

Abstract: In an aerosol inhaler it is proposed that a thermal sensor 5 be arranged in the region of the atomization nozzle 4, which sensor, following the actuation of an actuating element and the triggering of an inhalation process, undergoes cooling as a result of the expansion of the propellant which then occurs. The actuation and cooling are electronically detected in an electronic module 3. Technical and therapeutic data can be derived from the signal, which data are communicated to the user via the display unit and/or alarm devices and influence the therapy in the desired manner. See FIG. 1.
