| 20110048670 | METHOD FOR THE TEMPERATURE-DEPENDENT SETTING OF A SEALING GAP IN A REGENERATIVE HEAT EXCHANGE, AND THE RESPECTIVE ACTUATING APPARATUS - The invention relates to a method for temperature-dependent setting of a sealing gap between an adjustable seal and a revolving rotor of a regenerative heat exchanger by means of at least one actuating apparatus which comprises at least one rod body which is thermally influenced in an alternating manner and whose temperature-dependent change in axial length is converted into an actuating movement for the seal. It is provided in accordance with the invention that this rod bod is arranged at least in sections in a chamber and a control medium flows through or about this chamber at least in part, which medium acts in a direct or indirect manner in a thermally alternating fashion on said rod body, with the temperature level of the control medium corresponding to a temperature level of a gas volume flow flowing through the rotor, so that a change in axial length of this rod body is produced depending on a temperature change of this gas volume flow and a respective actuating movement for the seal is brought about. | 03-03-2011 |
| 20100163208 | Method For Operating A Regenerative Heat Exchanger And Regenerative Heat Exchanger Having Improved Efficiency - A regenerative heat exchanger, including a rotor mounted so it is rotatable, which has at least one first gas volume flow to be heated and at least one second gas volume flow to be cooled flowing through it, as well as a method for operating the regenerative heat exchanger, is provided. The inflowing first gas volume flow enters the rotor at a first front side of the rotor and exits the rotor again at a second front side of the rotor at an outflowing first gas volume flow. To increase the heating performance, a leakage volume flow is captured at the first front side of the rotor and supplied to the inflowing first gas volume flow and/or a leakage volume flow is captured at the second front side of the rotor and supplied to the outflowing first gas volume flow. | 07-01-2010 |
| 20100089477 | Plug for Sealed Closing of a Pipe - A plug for the sealed closing of a pipe is provided. The plug comprises a sleeve and a cylindrical main body having a connection for a pressure line. The sleeve is coupled to the cylindrical main body so that the sleeve and the cylindrical main body form an outwardly sealed pressurized area, which communicates with the connection. | 04-15-2010 |
| 20100059216 | Heat Exchanger In A Modular Construction - The invention relates to a heat exchanger in modular construction, in particular for facilities operated using large load and/or temperature changes, having an external shell and a number of heat exchanger modules, wherein each heat exchanger module, which is either a preheater, evaporator, or superheater module, has an entry manifold, and exit manifold, and meandering pipes, through which the heat-absorbing medium, in particular water, flows from the entry manifold to the exit manifold, and the heat exchanger modules are also situated in a shared external shell, so that they have the same heat-dissipating medium flowing around them, the evaporator modules being connected in parallel via a steam-collecting drum situated outside the external shell. | 03-11-2010 |
| 20090165648 | Method and Apparatus for Electrostatically Charging and Separating Particles That Are Difficult to Separate - The subject matter of the invention are electrostatic filter method and electrostatic filter for separating particles from industrial waste gases, whereas an optimal electric charging or ionization in the ionization zone are performed in a high-voltage zone and its unchanged ducts with one high-voltage supply source to ensure the subsequent particle separation in the separation zone at sufficient field strength which requires minimal energy input. | 07-02-2009 |
| 20090056908 | Regenerative heat exchanger - The invention relates to a regenerative heat exchanger for the heat exchange of gaseous media with a substantially cylindrical heat storage body. The invention further relates to a radial seal for use in a regenerative heat exchanger and a method for separating gaseous media in a regenerative heat exchanger. The heat storage body of the regenerative heat exchanger comprises a plurality of radially extending sector walls which subdivide the heat storage body into sectors. At least two heat storage chambers which are arranged behind one another in the radial direction are provided within a sector, which heat storage chambers are arranged for the through-flow of gaseous media. Radial seals are further arranged on the face side of the heat storage body for separating the gas streams, which seals form cover surfaces for the heat storage chambers and cover the heat storage chambers in an alternating manner during the operation of the regenerative heat exchanger, with the radial seals and the heat storage body being twistable relative to each other. In order to prevent the occurrence of oscillations which are caused by the pressure differences prevailing in the heat storage body between the individual gas areas, the radial seals are arranged in such a way that of the heat storage chambers of a sector which are arranged behind one another they cover at most partly the opening of at least one heat storage chamber in any rotational position. | 03-05-2009 |
| 20090020012 | METHOD FOR THE BACKFLUSHING OF FILTERS - Air filters comprising thin-walled textile filter bodies have to be cleaned periodically. According to a method known to this purpose, the filtered material is loosened using pressure pulses in a flushing air flow. According to the invention, for generating the pressure pulses a plurality of small, quick-acting valves are in each case briefly opened, the opening moments being adapted to one another in such a way that partial pulses released thereby arrive simultaneously at the inlet of a flushing line common thereto. | 01-22-2009 |
