    Abstract: An arrangement for storing energy to cover peak-load conditions and serve as a stop-gap reserve in steam power plants. A live steam generator is connected to a steam turbine, and a storage vessel is provided with a steam cushion volume and a water content volume. The water content of the storage vessel is connected, on the one hand, to a single-or multi-stage secondary steam generator which is connected, in turn, on the steam side to the turbine by a working steam line. A hot-water return line connects the secondary steam generator on the water side to the feed water line and/or a compensation vessel connected to the feed water line. The steam cushion volume of the storage vessel is connected, on the other hand, by a steam line, to a point of the main steam cycle of the plant which is upstream of the entry point of the working steam line. In particular, the steam cushion is connected to the live steam line. The secondary steam generator may be in the form of one or several flash tanks or heat exchangers. It also may consist of several superheaters through which hot water flows.

    Abstract: A method and apparatus for cooling hot bulk material in a cooling bunker by passing cooling gas streams therethrough in a manner such that the bulk material is cooled in a uniform manner while avoiding temperature fluctuations of the outflowing heated cooling gas. The cooling gas is passed through the hot bulk material in at least two gas streams, one of which is directed through a core zone of the hot bulk material and another of which is passed through a peripheral zone thereof. The flow rates of the respective cooling gas streams are regulated according to the temperature of the outflowing heated cooling gas which may be sensed by the temperature of a fluid flowing through heat exchanger over which the heated cooling gas passes.

    Abstract: A method of generating a low-tar generator gas includes contacting the hot tar-containing generator gas in a contact zone with ballast bodies to cool the generator gas and capture tar and dust on the exposed surfaces of the ballast bodies, and admixing the thus heated ballast bodies to the wet solid fuel to be gasified to dry and pre-heat such fuel in preparation for the actual gasification which is performed in two separate gasification zones which are arranged one above the other by reacting the solid fuel with an oxygen-containing gasification medium that is introduced from above into the upper one, and from below into the lower one, of the gasification zones with attendant formation of two conflagration fronts in the gasification zones. The generator gas which is thus generated in the two gasification zones is discharged through a common discharge conduit which has the contact zone incorporated therein. An arrangement for performing this method includes a contact apparatus which bounds the contact zone, is incorporated in the discharge conduit and contains a bed of the ballast bodies, the bed being replenished by ballast bodies which have been separated from ashes after they have been discharged from the lower one of the gasification zones.

    Abstract: A method of autoclaving porous piece-goods, by steam under pressure, wherein the autoclaving operation includes sequential phases of heating with steam, holding, and then relaxing the pressure and temperature, wherein the holding phase includes a drying process. In order to obtain as dry a product as possible with the smallest possible energy input, it is provided that a drying process is carried out within the holding phase in which the autoclave is heated more than to compensate for heat losses and to a temperature above the temperature of vaporization of the water so that the material is dried by controlled discharge of steam from the interior of the autoclave. The steam discharged from one or more autoclaves during the drying process is used to heat up at least partially an autoclave to be heated.

    Abstract: Method for gasifying carbonaceous fine-grained or sludgy material, such as powdered brown coal or biomass, in fixed bed reactors. Carbonaceous material to be gasified is pre-heated and dried, and mixed with coarse-grained, non-carbonaceous ballast material. This mixing is carried out prior to, during or after the pre-heating and drying of the carbonaceous material, to thereby obtain a pre-heated and dried mixture of the carbonaceous material and the ballast material, and to also obtain vapor from the pre-heating and drying of the same. The heated and dried mixture is contacted with a gasification medium within a fixed bed reactor, at a temperature sufficiently high to gasify the carbonaceous material. The gasification medium includes the vapor from the pre-heating and drying of the carbonaceous material. The ballast material provides sufficient gas permeability to the fine-grained or sludgy carbonaceous material, to permit gasification thereof in the fixed bed reactor.

    Abstract: A method and apparatus for mixing a first relatively cool gas current and a second relatively hot gas current in a manner such that the resulting gas current has a relatively uniform temperature immediately subsequent to the point of mixing. The first gas current is separated into first and second partial gas currents, the first partial gas current being directed to a conduit which branches from the conduit in which the second partial gas current is directed. The first partial gas current is directed at a relatively high velocity into a central nozzle in fluid communication with the second gas current while the second partial gas current is directed into a ring nozzle which also is in fluid communication with the second gas current and which concentrically surrounds the central nozzle. The flow of the first gas current is regulated by throttling the second partial gas current while maintaining the flow of the first partial gas current. The method and apparatus has particular application in the regulation of the inlet temperature to a heat exchanger of a cooling gas current in a dry cooling plant for hot bulk materials, such as coke.

    Abstract: A steam generator having an elongated vessel provided with opposed upper and lower ends and having in its interior adjacent its upper end a single transversely extending tube plate and a partition extending upwardly from said tube plate and dividing the interior space of the vessel above the tube plate into a heating-medium receiving chamber and a heating-medium discharge chamber. A bundle of tubes are connected with and extend downwardly from the tube plate to the region of the lower end of the vessel, each of these tubes having an inlet end communicating with the receiving chamber and an outlet end communicating with the discharge chamber and each of these tubes having a substantially U-shaped configuration at the region of the lower end of the vessel. A feedwater supply communicates with the vessel below the tube plate to supply to the interior of the vessel a liquid to be converted into steam with heat extracted from the heating medium which flows through the tubes from the receiving chamber to the discharge chamber. Above the liquid which is in the vessel there is a steam chamber defined at least in part by a lower surface of the tube plate at that part thereof to which the inlet ends of the tubes are connected, and a steam discharge conduit communicates with the steam chamber to receive live steam therefrom.
