Abstract: Sulfurous fuel and CaCO3-containing sorbent are combusted in a furnace of a circulating fluidized bed boiler. A dry circulating fluidized bed scrubber includes a reactor with water and Ca(OH)2 feeds for converting SO2 in the exhaust gas to CaSO3 and CaSO4 and a dust separator in gas flow connection with the reactor. A discharge removes CaO-containing bottom ash from the furnace. A classifier classifies a portion of the removed CaO-containing bottom ash into coarse and finer portions. A fine ash channel conveys some of the finer bottom ash portion from the classifier to a grinder. A ground ash channel conveys some of the ground bottom ash portion from the grinder to a hydrator to hydrate CaO in the ash to Ca(OH)2. A hydrated ash channel conveys some of the Ca(OH)2 from the hydrator to the dry circulating fluidized bed scrubber as a sorbent.

Abstract: A scrubber for removing pollutant compounds from a gas stream. At least one gas channel introduces the gas stream to a lower portion of the scrubber. An inlet chamber directs the gas stream upwards to form a vertical gas stream. A constriction section has a vertical axis of symmetry and includes a centrally arranged venturi nozzle, and is above and in flow connection with an upper end of the inlet chamber for accelerating the vertical gas stream. A reaction chamber is arranged above and in flow connection with the constriction section. A reagent in the reaction chamber converts pollutant compounds in the gas stream to reaction products. A discharge channel in flow connection with the reaction chamber discharges gas and particles including the reaction products from the reaction chamber. A particle separator separates particles from the gas. A return channel recycles a portion of the particles to the reaction chamber.

Abstract: A method for controlling an electric motor of a vehicle pump used to deliver a medium. According to the method, a period required for at least one partial revolution of a rotor of the electric motor is determined. The fluctuations during the period can represent a measurement of the true running of the electric motor. The speed of the electric motor can be altered depending on the deviation of the period from a comparative value. As a result, the true running of the electric motor can be guaranteed once again.

Abstract: A fuel pump of a motor vehicle includes: a pump stage configured to induce fuel from a fuel tank; an electric motor configured to drive the pump stage; and control electronics configured to supply the electric motor with electrical current. The control electronics includes a memory storing a low temperature start program and a standard start program. The control electronics are connected to a temperature sensor and a selector configured to select the start program depending on the sensed temperature.

Abstract: A housing for an electronic circuit for a fuel pump includes a base and a cover which is connected to the base, a printed circuit board and, disposed on one side of the latter, electric and/or electronic components. Disposed on the side of the printed circuit board on which the components are disposed is a self-contained metal strip. The components are arranged in the region surrounded by the strip. A cover is soldered to the self-contained strip in such a way that the printed circuit board forms a base, the cover forms a housing, and the printed circuit board has at least one blocking layer.

Abstract: During monitoring of an electromotively driven fuel pump of a fuel feed unit for a motor vehicle, a pump current is monitored as a function of a pump voltage or of a pump rotational speed. Through a comparison of the pump current with the pump voltage or the pump rotational speed, it is detected whether leakage or dry running of the fuel pump is present. The fuel feed unit does not require any pressure sensor for this purpose, and is therefore of particularly simple construction.

Abstract: The present invention relates to a reliable method of prediction of sepsis in humans after a trauma, wherein the level of pancreatic stone protein/regenerating protein (PSP/reg) is determined in serum, and a high level is indicative of the development of sepsis at early stages of the disease. Furthermore a method of determination of PSP/reg levels in serum is described.

Abstract: In a method for operating a fuel pump in order to guide fuel from the fuel container of an internal combustion engine, the electric energy, which is in the form of pulses, is periodically guided to the fuel pump and the duration of the pulses is controlled according to the fuel required by the internal combustion engine. The frequency of the pulses is controlled in such a manner that, in the event of low pump rate of the fuel pump, the frequency is controlled to a higher level than in the even of a high pump rate.
