Patent number: 6621271Abstract: A device for controlling the operation of a vehicle battery exhibits two current paths for connecting the battery to the vehicle electrical system. Here, the first current path allows current to flow in both directions and the second current path only allows a charging current to flow from the vehicle electrical system to the battery. In addition, the first current path contains a switch which is only closed when the voltage at the generator connection is less than a predetermined value. Apart from this, a measuring device which measures a change in the state of charge of the battery, a storage device which stores the instantaneous state of charge of the battery, and a checking device which checks a predetermined electrical criterion for the maximum attainable state of charge of the battery, are provided.Type: GrantFiled: June 26, 2002Date of Patent: September 16, 2003Inventor: Georg Ziegler

Patent number: 6311647Abstract: After the economizer, an injection water pipe branches off the connecting pipe between economizer and evaporator in order to control the steam temperature. The injection water pipe is provided with a control device for controlling the injection water flow. The injection water flowing through the injection water pipe is injected into the steam coming from the evaporator at a mixing point located before the superheater. In order to control the position of the control device in the injection water pipe, the enthalpy at the superheater outlet is calculated from the parameters pressure and temperature and is compared with a desired enthalpy resulting from the desired parameters.Type: GrantFiled: January 18, 2000Date of Patent: November 6, 2001Assignee: Alstom (Switzerland) LtdInventors: Erhard Liebig, Rudolf Herzog, Hamid Olia, Wolf-Stephan Wilke, Georg Ziegler

Patent number: 6269754Abstract: The invention relates to a steam generator (1) for superheated steam for incineration plants with corrosive flue gases, essentially comprising a radiation section (2) and a convection section (5), having at least one superheater (8) and having plates (10) arranged on the inside of at least one wall (9) of the radiation section (2), a space (12) being provided between the plates (10) and the wall (9) of the radiation section (2), and at least part of the superheater (8) being arranged as a wall superheater (15) in the space (12) in the radiation section (2). The steam generator is distinguished by the fact that the space (12) contains a noncorrosive gaseous atmosphere which is at a higher pressure than the pressure of the gases in the combustion chamber (3). In this way, it is possible to reach a high superheater temperature without corrosion to the final superheater, so that the superheater can be made from inexpensive material.Type: GrantFiled: August 20, 1999Date of Patent: August 7, 2001Assignee: Asea Brown Boveri AGInventors: Hans Rüegg, Georg Ziegler

Patent number: 5983840Abstract: The invention relates to a steam generator, which consists of a combustion chamber (1), a radiation part (2) and a convection part (3) and which has at least two vertical gas passes (4, 5) following the combustion chamber (1), in each case with a 180.degree. deflection of the flue gas (12), the combustion chamber (1) and the gas pass (4) being separated from one another by means of a first partition (14) and the two gas passes (4, 5) being separated from one another by means of a second partition (6). It is defined in that the second partition (6) is designed, at its lower end, in such a way that the passage area for the flue gas (12) from the vertical pass (4) with downward flow to the vertical pass (5) with upward flow has a variable value over the width, the passage area being smaller in the middle than on the outside. The secondary flow occurring during deflection is thereby reinforced, in the wall region the vortices of said secondary flow rotating opposite to the direction of the main flow deflection.Type: GrantFiled: September 16, 1998Date of Patent: November 16, 1999Assignee: Asea Brown Boveri AGInventors: Oliver Riccius, Georg Ziegler

Patent number: 5568793Abstract: In a steam generator having a convective part arranged downstream of the furnace chamber and essentially consisting of final superheater (1), pre-superheater, evaporator and economizer connected in series on the flue-gas side, a further contact heat exchanger (5) having a plurality of tube banks (10) is arranged upstream of the final superheater (1). This contact heat exchanger (5) is connected to the steam drum (6) in such a way that it can be operated as both an evaporator and a superheater. The working medium to be heated flows in parallel from the bottom to the top through the tube banks (10), as a rule arranged vertically or inclined, of the contact heat exchanger in the evaporator circuit and flows in series through said tube banks (10) of the heat exchanger in the superheater circuit.Type: GrantFiled: January 10, 1995Date of Patent: October 29, 1996Assignee: ABB Management AGInventor: Georg Ziegler

Patent number: 4487611Abstract: The gas cooler has a downcomer bounded by radiant cooling walls and a waterbath at the end of the downcomer. The depth of the waterbath is several times its horizontal extent and the waterbath is flowed through downwardly by water. The bath is connected by way of a pump, heat exchanger and a feed line to a water circuit. Means are provided to control the water temperature at its entry into the waterbath so that the entry temperature is maintained at a value somewhere between the dew point of the synthesis gas and the evaporation point of water at the working pressure of the synthesis gas.The result is substantial obviation of evaporation of water from the waterbath and the associated heat losses.Type: GrantFiled: September 22, 1982Date of Patent: December 11, 1984Assignee: Sulzer Brothers LimitedInventor: Georg Ziegler

Patent number: 4385501Abstract: The hot gas cooler has a cooling insert of tubes in the pressure vessel. At the hot gas entry end, the cooling insert is connected, to a hot gas source. The insert interior communicates with the gap between the insert and the pressure vessel for pressure compensation. The pressure-compensating communication is disposed near the hot gas entry and extends by way of an additional cooling path. In the event of a gas-side leakage of the cooling insert, hot gas cannot flow into the gap between the insert and the pressure vessel.Type: GrantFiled: September 15, 1981Date of Patent: May 31, 1983Assignee: Sulzer Brothers LimitedInventor: Georg Ziegler
