摘要:
Exhaust gas amitted from a diesel engine flows through a ceramic soot filter in which particles contained in the exhaust are deposited and oxidized to regenerate the filter. The filter is regenerated by non-thermal, electric surface creeping discharge on filter surfaces covered with particles. In addition, nitrogen oxides may be reduced by selective catalytic reduction. The system is designed to ensure operation reliability and environmental compatibility.

A business object model, which reflects data that is used during a given business transaction, is utilized to generate interfaces. This business object model facilitates commercial transactions by providing consistent interfaces that are suitable for use across industries, across businesses, and across different departments within a business during a business transaction. In some operations, software creates, updates, or otherwise processes information related to a business document message monitoring view, a customs arrangement, and/or a freight list business object.

A barrier system for a line leadthrough in an electric installation has mutually adjacent wall elements forming barriers that extend in an axial longitudinal direction and are spaced apart from each other, forming channels. The wall elements lie partially on a support, at least at their lower ends. The wall elements are joined by a plug element to the leadthrough. Slots having a width which corresponds to the wall thickness of the wall elements are arranged in the plug element. The wall elements can be inserted into the slots, thus permitting a barrier system to be quickly and easily assembled and disassembled.
摘要:
A method in which CO2 is placed on an adsorber and an adsorption reaction with ammonia, that is used as a chemical absorption agent, occurs, is provided. The CO2 extracted from the waste gas is joined to the ammonia on the catalytic surface using a heterogeneous, catalytic reaction. At least two reactors are provided in the associated device. The reactors, which operate alternately, are switched between the adsorption of CO2 and the regeneration of the absorption agent.

A method of operating a combustor (10), to provide intimately mixed hot combusted gas (44) for a gas turbine (46), includes feeding gaseous oxidant (12) and gaseous fuel (16) into the combustor (10) near a combustion flame (28) which has a tip end (39) and a root end (29), where corona discharge occurs through adjustment of an electric field (34), and where the corona discharge causes ionized particles (36) to form and also causes intimate turbulent mixing of the gases.

In particular for exhaust-gas purification, different processes have been proposed. According to the invention, the polluted exhaust gas flows through a reactor volume to which non-thermal gas discharges are applied, while being brought into contact with a solid reducing agent at least once, and preferably several times. The reducing agent can, in particular, consist of carbon fibers. A suitable device for combining dielectric barrier discharges with the reduction has means for field enhancement substantially periodically spaced in the reactor.

A reel for photographic paper has a hollow cylindrical core and two disk-shaped flanges having centrally located extensions received in the respective end portions of the core. The inner side of each flange tapers outwardly in a direction from the periphery of the core toward the periphery of the respective flange. The extensions have ribs which penetrate into the inner surface of the core, and the core is further coupled to each flange by a rubber hose which surrounds the respective extension and is biased against the inner surface of the core by an endless helical spring which surrounds a conical end face of the corresponding extension.

Waste water from an industrial process, including an organic acid, is reprocessed by introducing the waste water into a heat exchange process in which a heat exchange medium is used so that the waste water which is to be treated is heated to a temperature between 60° C. and the boiling point of the waste water. Subsequently, the waste water is partially evaporated and re-condensed, with the waste water irradiated with UV radiation during the evaporation and condensation process in the liquid and/or gas phase. As a result, a chemical transformation of the organic acid in H2O and carbon dioxide is at least partially carried out. Then, the condensed part of the purified waste water is fed back into the industrial process.

摘要:
For monitoring a combustion process in an internal combustion engine wherein a fuel-air mixture is ignited with a high-frequency plasma it is provided to determine the impedance of the plasma. A high-frequency signal is applied to the resonator with a capacity that is so low that no arcing-over forms on the electrodes and the high-frequency current and the high-frequency voltage are measured. The impedance of the ignited mixture is determined from the high-frequency current and the high-frequency voltage.
