Power electronics are further accommodated in the interior of the housing of the battery module. The housing includes a projection which is configured to protrude beyond a remaining part of the housing, and the power electronics are at least partially accommodated within the interior of the projection.

Abstract: A process for the endothermic gasification of solid carbon in an entrained bed facility comprises partial oxidation of fuel(s) and endothermic gasification of solid carbon, preferably preceded by low temperature carbonization such that the carbonization gas is passed to the partial oxidation and the carbonization coke is passed to the endothermic gasification. The hot gas streaming downwardly from the combustion chamber is deflected to produce separation of the liquid slag and is then passed to the endothermic gasification that operates with a rising gas stream and with addition of solid carbon having a grain diameter of up to 20 mm. The speed of the gas at the carbon inlet is higher than, and the speed of the gas at the end of the endothermic gasification is lower than, the suspension rate of the reactive carbon particles, to produce an increase of the relative speed difference between the gas and the carbon particles. Apparatus is also disclosed for carrying out the process.

Abstract: During required change-over to a holding operation in a Fischer-Tropsch synthesis, the reactor is not depressurized after cutting off the supply of fresh synthesis gas to the Fischer-Tropsch reactor, and the temperature is not reduced to below the temperature below which a Fischer-Tropsch reaction no longer takes place. Instead, the reactor is charged with an inert gas, e.g., kept in a vessel at a pressure higher than the operating pressure of the Fischer-Tropsch synthesis, until the reacting components have been flushed out from the Fischer-Tropsch system. While maintaining the pressure and the temperature, the reactor is thus merely inerted for a few seconds, sufficient to interrupt the Fischer-Tropsch reaction. Catalyst damage is avoided, and the liquid phase situation on the catalyst is at least essentially unchanged, facilitating subsequent re-commissioning of the catalyst.

Abstract: The invention concerns a process for the production of pig iron with the help of blast furnaces or other suitable devices in which iron-containing materials are reduced and melted in the presence of fuels.

Abstract: The invention relates to a method for rotational position determination of an internal combustion engine having a camshaft to which a camshaft sensor is assigned and having a crankshaft to which a crankshaft rotational position transducer is assigned. A control apparatus for controlling the engine includes at least one configurable control apparatus input. After detecting a fault function of the crankshaft rotational position transducer, the control apparatus input of the control apparatus switches to the evaluation of one of the flanks (9.1, 10.1, 11.1, 12.1; 9.2, 10.2, 11.2, 12.2) or of all flanks (9.1, 10.1, 11.1, 12.1; 9.2, 10.2, 11.2, 12.2) of pulse segments (A, C, E, G). Thereafter, an injection of fuel takes place into the cylinders of the engine until an rpm gradient is detected which makes possible a position determination of the rotational position of the crankshaft of the engine.

Abstract: Disclosed is a method for producing pig iron using blast furnaces or other appropriate devices, in which materials containing iron are reduced and smelted in the presence of fuels. According to the invention, metallurgical coke can be converted into reduction gas and coke using economical organic exchange gases by combining a multistep process for exchange fuel gasification and a blast furnace process, into which the products of the gasification are fed together or separately at a height of the mouth of the tuyere or through the latter into a melt. The gasification process is also used in the prereduction or iron oxides, fine ores and ore concentrates.

Abstract: A process is disclosed for generating burnable gas by gasifying water- and ballast-containing organic materials, be it coal or garbage. The drying, low temperature carbonization and gasification steps are carried out separately. The heat taken form cooled gasified gas is supplied to the endothermic drying low temperature in low temperature carbonation stages. The low temperature carbonization gas is burned in a melting chamber furnace with air and/or oxygen or oxygen-rich flue gas and the liquid slag is evacuated, whereas the low temperature carbonization coke is blown into the hot combustion gases that leave the melting reactions which take place and give carbon monoxide and hydrogen reduce the carbon is removed from the gasified gas, supplied to the melting chamber furnace and completely burned.

Abstract: In a process for the low-pollutant conversion of thermal energy produced by burning fossil fuels into power, the thermal energy produced by burning fossil fuels is delivered directly to the cyclic process by virtue of the fact that in the cyclic process the fuels are burned with oxygen in the presence of carbon dioxide recycled from the cyclic process to form gas turbine operating substances having a temperature of from 800.degree. to 1500.degree. C. Furthermore, according to the invention, the pressure difference between the combustion chamber (1) and the carbon dioxide recycling process is compensated by condensation (11), on the one hand, and evaporation (4, 8) and pre-heating (3) of the carbon dioxide to be recycled and the combustion chamber (1), on the other, by compression (7) and expansion (6) which are performed during the process, preferably with a high-performance gas turbocharger (6, 7).

Abstract: A process and apparatus are disclosed for drying solid materials, which allows the thermal energy used for drying to be recovered and the emissions produced during degassing and gasification to be reduced. A solid material which contains an evaporable material, particularly water, is fed to a fluidized bed drier. The solid material is fluidized by fluidizing medium, the fluidizing medium being the evaporable material. The dried solid material is removed from the drier and is fed to further processing, use or disposal. The non-condensable components of the solid material which are insoluble in the condensate of the evaporable material are separated by cooling and condensation of the vapor and released for subsequent use or disposal.

Abstract: A partial flue gas stream is used for the production of electrical energy and/or heating and operational heat by utilizing combustion heat from fossil fuels, prior to combustion dried in an indirectly heated fluidized bed dryer, with combustion flue gas used as a carrier medium for the fluidized bed dryer. The mixture of flue gases and steam, deriving from the drying process, is after an intermediate treatment, if necessary, discharged with the main flue gas stream.

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.
