Abstract: Method and data access unit for storage of data records for creating a serialized charging record formatted for insertion into a charging database. The method includes traversing the hierarchical charging record and for each part node of said hierarchical charging record identifying an attribute of the part node and determining if said attribute is a key attribute or a search attribute and if affirmative storing an attribute value of said attribute in a field of the serialized charging record based on a charging database configuration definition. A part segment comprising the attribute value and a data value token is stored in a payload body field of the serialized charging record with a part node indicator representing the location of the part node in the hierarchical charging record based on a hierarchical charging record configuration definition. A method and data access unit for creating a hierarchical charging record is also disclosed.

Abstract: The plant has a generator for a refrigerant in rich solution. A condenser is connected downstream of the generator in the refrigerant loop. A first expansion valve is connected downstream of the condenser. The refrigerant vapor produced there is directed into the sump of an absorber. The liquid refrigerant passes from the first expansion valve to a second expansion valve which adjoins an evaporator. Arranged in the absorber is a jet apparatus, whose nozzle is fed with the weak solution from the generator and whose suction space is connected to the evaporator. The weak solution therefore draws the refrigerant vapor out of the evaporator and delivers it into the top region of the absorber. There, a deflection takes place, whereupon the solution that is increasing in concentration is directed over cooling coils and passes into the sump of the absorber. In this way, very effective droplet, film, trickling and immersion absorption occurs.

Abstract: A reactor (7) for gasifying materials that contain carbon under pressure has a tube wall (20) that has coolant flowing through it and is lined with a refractory material (21). The outlet (9) from the reactor (7) points down and opens into a cooler (10). The reactor is accommodated in a pressurized vessel (1) along with the cooler (10) and can be released and removed independently.

Abstract: An arrangement for cooling a synthetic gas, generated in a gasification reactor, by means of a quenching cooler. The cooler is positioned below the outlet from the reactor and comprises a refrigerated inner jacket (5) surrounded by a pressurization jacket (1) and accommodating a water sump (6). There is an intermediate section (3) between the inner jacket and the outlet from the gasification reactor that is shorter in diameter than the inner jacket and longer in diameter than the outlet from the reactor. Spray nozzles (15) extend into the inner jacket. One or more gas-outlet connections (8) extend through the inner jacket in a plane above the sump.

Abstract: A cooler for gases generated from coal by gasification under pressure has a pressurized vessel (1) that accommodates an insert (5) with a polygonal cross-section made out of pipes (6) that are welded together gas-tight in conjunction with webs (7). The pipes in the insert are bent vertically in to create a roof (11) and parallel one another sector by sector with webs of uniform width. The pipes that abut at an angle at the edges of the sectors are united in pairs by forged crosstail butts (13). The crosstail butts are aligned along a straight line and completely occupy the spaces between the sectors.

Abstract: A device for cooling hot, compressed, dust-laden gases. The device consists of an inner structure made out of cooled tubes, positioned inside a pressurized container. The device contains several straight partitions made out of tubes. The partitions parallel the longitudinal axis of the inner structure. The object is to redesign the heat-emitting surfaces of the device in order to make it more compact. At least one of the straight partitions is bent out into a nest of tubes. The nest extends through the cross-section of the inner structure. The tubes that the nest is made out of extend through and are supported by the rest of the partitions.

Abstract: Convection cooler for cooling a gas produced under elevated pressure in a gasification reactor. The cooler has a pressure-tight jacket provided with a removable cover. Within the jacket there is an insert arranged spaced apart therefrom. The insert has tubes joined in gastight manner to each other by way of webs. Contact heating surfaces are arranged in the insert which is supported on the pressure jacket. The insert is closed at its upper end by way of a ceiling constructed of tubes. The contact heating surfaces are joined to support tubes. The upper ends of the contact heating surfaces and the support tubes are passed through the ceiling. The support tubes, the contact heating surfaces, and the ceiling are suspended from the cover independently of the insert. Wall soot blowers are arranged fixedly superimposed at several levels in the insert.

Abstract: A pneumatic or electrical signal indicating the flow mass of a fine-grained fuel suspended in a carrier gas is produced by computer means. The input for the computer is constituted by the quantity determined for the volume of the carrier gas and the quantity determined for the density of the carrier gas together with the quantity determined as the specific weight of the fuel and the quantity determined by a radiometric measurement of the total density of the fuel and carrier gas flow. The computer is programmed to produce the above signal on the basis of a mathematical relationship defined in the above text. A valve controlling the feed of fuel into a gasifier is operated by the signal produced by the computer.

Abstract: The fuel flow into the gasifier of a partial oxidation installation using solid fine-grain or dust-like fuel is determined by a radiometric density measurement of the fuel immediately prior to its entry into the gasifier and while the fuel particles are suspended in a gaseous or vaporous medium.
