Abstract: A device for incinerating solid and/or liquid toxic substances, especially projectiles filled with chemical warfare agents. Because the ammunition to be incinerated may have been inadvertently not disarmed the incinerator plant must be able to withstand an operating pressure of at least 40 bar. The incineration includes a rotatably mounted unit consisting of a rotary tubular kiln, an afterburning chamber, and a waste heat boiler. The unit is designed in a corresponding pressure-proof manner, and the rotary tubular kiln as well as the afterburning chamber are lined with refractory material. The operating pressure is generated by a compressor arranged upstream of the incinerator plant, and it is released by an expander arranged downstream of the entire plant.

Abstract: A sealing medium seal for sealing the rotary drum of a drum-shaped furnace against the stationary charging device and the downstream, stationary discharge chamber, in order to prevent infiltrated air from being drawn into the process space and toxic flue gases from surging out. A double seal is provided including wearable individual sections of the sealing ring, which are equipped with a circumferential groove, with a hole, and with a sleeve for the sealing medium connection, and are arranged displaceably between two flanges as well as of a pneumatic, deformable, one-part sealing element, to which pressurized medium is admitted via a connection. The two sealing elements are guided in a chamber formed by two side flanges and a closing flange, as a result of which the sealing elements are completely sealed both in the radial direction and in the axial direction.

Abstract: A bulk material loading and unloading facility for sea-going ships with displaceably arranged bulk material loading and unloading devices (23). Instead of a pier or a dock facility and a shore-side storage facility equipped with stackers and reloading devices and the conveyor belt units needed for them, a trough-shaped bulk material storage facility (14) is arranged on the ocean bottom (3) at a water depth that is safely navigable for sea-going ships, and rails (22) are laid on the side walls (15) of the bulk material storage facility. Loading and unloading devices (23) travel on these rails, and the loading and unloading devices (23) convey bulk material from ships (28) into the trough-shaped storage facility (14), or onto a conveyor belt unit (25) leading from this storage facility directly to a bulk material processing facility (e.g., a coal-fired power plant).

Abstract: A geared multishaft turbocompressor with impellers arranged in series in terms of flow, are attached to two or more pinion shafts (6), which are arranged in parallel to one another and are driven directly via a central gear (5) or indirectly via pinion shafts at the circumference of the central gear (5). A plurality of impellers (8, 8a) are arranged in series, via the interstage diaphram of a disk-type diffuser (9) and of a return ring (10), on at least one pinion shaft end (6) in high-pressure stages following low-pressure stages (first pinion shaft or first and second pinion shafts) after the second or third pinion shaft (6). Reversing the direction of flow, i.e., admission of the gas on the high-pressure side and discharge of the gas on the low-pressure side, as well as with simultaneous reversal of the direction of rotation, a radial expander (turbine) is obtained with the same basic design.

Abstract: A process and a device for the simultaneous tensioning and loosening of eccentric tension rods (19) of gas turbine rotors assembled from several turbine disks (23). An improved hydraulic tensioning device is used to provide an optimal circular and flat impact quality, and the quiet running of the gas turbine rotor is improved overall at high speeds. Further, it is guaranteed that the same forces act on each tension rod (19), the elongation of each tension rod (19) can be measured as accurately as possible, and a minimization of the setting force losses is achieved. A solid cylindrical ring (1) forms a piston chamber (11) in each case, whereby the piston chambers (11) are connected together with cross holes and are acted on by the hydraulic medium. The catch pin (3), through which a measuring rod (5) is guided, which makes contact with the head of the tension rod (19) by a pressure spring (18), is inserted through a boring in the piston (2).

Abstract: A tilting device for a direct current arc furnace and a process are disclosed for completely emptying the furnace while the furnace is operated with a continuous scrap supply through a lateral opening in the furnace vessel and removal bottoms. The scrap chute should remain in the opening of the furnace during the loading, melting, deslagging and tapping operations; it should be swiveled away only during the emptying of the furnace. The disclosed tilting device has a cam on the rolling cradle, so that the rolling mid-point remains at the zero position in a tilting range from .+-.5.degree. to .+-.15.degree., and when the furnace is completely emptied it moves to another position in a parallel direction to the bottom tapping opening. The position of the bottom tap opening changes only insignificantly in order to protect the parts of the bottom electrode located outside the vessel of the furnace from heat radiated by steel in the casting ladle.

Abstract: The present invention pertains to a thermoelastic connection of a hot gas-carrying injector tube (8) to the flame tube (1) suspended in the combustion chamber housing (10) of a gas turbine. The injector tube (8) is connected by corrugated spacers (7) to a circumferential intermediate ring (6), which is attached to the lower flange of the flame tube (1) by detachable fastening elements (3, 4, 5). A circumferential cooling channel (annular space 15), into which cooling air is admitted, is formed between the cone of the injector tube (8) and the intermediate ring (6). The compressor air enters the combustion space (1, 8) of the combustion chamber (10) through the annular space (15) from below, as well as through the holes (11), especially through the circumferential gap (12).

An inflatable container (6) is integrated in the structural part (2) of the launching support (8), and the container acts as a movable support in the filled state. A release mechanism (10) arranged in the vicinity of the container ensures that the medium--compressed air or nitrogen--will escape from the inflated container (6) when the end of the bridge (5) has completely reached the bearing (9) after advancing forward.

Abstract: The present invention pertains to a process for cooling and purifying hot, dust-laden flue gases enriched with dioxins and other toxic components from a melting vessel, e.g., an arc furnace.Both the flue gases A, B generated during charging and those generated during the melting operation are collected, and the toxic components are removed in two ways.The flue gases A collected in the exhaust hoods 2 are fed into the filter 6, while previously blowing an additive 12, on which the toxic components settle before reaching the filter bags, into the flue gas stream A.The hot flue gases B drawn off directly from the arc furnace 1 are introduced into a combustion chamber 3 after passing through a water-cooled section 4, and are subjected to afterburning in the combustion chamber 3 to remove the toxic pollutants. These gases are then intermediately cooled in a second, water-cooled section 5, further cooled by adding more additional cold air A, and fed into the filter 7.

In the area of the bricks (8), the metal rods (3) are additionally embedded in a nonconductive mass (11). To introduce inert gases to purge the melt through the bottom electrode (1), the metal rods (3) are provided with a cored hole and, in the upper part, with a number of radial holes in order for the purging gases to be able to be discharged in the area of the bricks (8), or blind holes (13), which are connected to a second purging gas line (13a), are introduced into the lower part of the lined bottom electrode (1).

Abstract: The present invention pertains to a combustion chamber housing of a gas turbine with a laterally arranged inlet elbow (8) for compressor air, which is uniformly distributed over the perforated cone (9) via an intake heart (6), impacts on the injector tube (10) there, and is deflected in the upward direction in the direction of the flame tube and the burner. It is necessary under certain operating conditions of the gas turbine to regulate the primary air flow to the burner, without having to reduce the output of the upstream compressor. This is accomplished according to the present invention by connecting a bypass line (3) with a compensator (1) and a regulating fixture (2), through which part of the air is sent from the air inlet elbow (8) directly into the interior of the injector tube (10) via an inlet tube (4), to the lower part of the combustion chamber.
