  • Patent number: 6694745
    Abstract: A method for running up a gas turbine plant (1) is disclosed. In the method, a fuel (6) is injected into the combustion chamber (5) via a plurality of pilot burners (10) and premix burners (11). During the start-up and in a lower load range, the combustion chamber (5) is operated in the pilot mode, and, at a specific time point, the combustion chamber (5) is changed over from the pilot mode to the premix mode. The changeover time point from the pilot mode to the premix mode depends on a variable changeover temperature (TSWO), and this changeover temperature (TSWO) is determined from pulsations occurring in the flame of the combustion chamber (5).

  • Patent number: 6161385
    Abstract: A turbomachine, in particular a gas turbine, is in the traditional manner provided with air cooling of the components that are subject to a high thermal stress. The cooling system (21, 31, 41) is provided with elements through which another medium (25, 35, 45), for example water or steam, can be added to the cooling system during peak demand. This medium displaces cooling air (26, 36, 46) from the cooling system, the air being then available additionally in a heat generator (2, 4). This means that more fuel (12, 13) can be added without increasing the hot gas temperature (T.sub.1, T.sub.3) at the turbine inlet (301, 501), and the power is increased. The quantity of the medium added to the cooling system is controlled by control elements (24, 34, 44) as a function of a control deviation (P.sub.set -P.sub.act) of the power.

  • Patent number: 5135553
    Abstract: During the production of solid CO.sub.2 pellets by compressing CO.sub.2 snow, in order to reduce the sublimation of the CO.sub.2 snow in the compressing step, the CO.sub.2 snow is subcooled with a cryomedium, e.g., argon or nitrogen. The compression mold may be separately cooled and the CO.sub.2 snow may be subcooled with liquid cryomedium while in a storage vessel and/or sprayed with liquid cryomedium while on a conveyor leading to the press.

  • Patent number: 5049330
    Abstract: A process and apparatus is provided for explosively forming plastic objects from shredded plastic such as recycled plastic having different compositions. The shredded plastic and an explosive gas mixture is introduced into a mold cavity having the shape of the object to be formed, and the gas mixture is ignited, generating sufficient heat and pressure to force the plastic to conform to the shape of the mold cavity. The temperature and pressure in the mold cavity is controlled during the explosion by releasing combustion gases from the mold cavity.

  • Patent number: 4966493
    Abstract: A process and apparatus are provided for cleaning contaminated earth. The contaminated soil is first frozen using freezer boxes which are placed on the surface of the ground to be frozen. A refrigerant, preferably liquid nitrogen, is then introduced into the box until the soil is frozen to a desired depth and temperature. The frozen soil containing pollutants is then removed and placed in sealed containers for optional further treatment.

  • Patent number: 4902529
    Abstract: For the fluorination of synthetic resin articles, e.g., containers, the article to be fluorinated is positioned in a gastight chamber, and a fluorinating treatment gas is produced from a fluorine precursor in situ, e.g., with the aid of a plasma torch from a basic gas mixture comprising a fluorine-containing compound, e.g., CF.sub.4 or SiF.sub.6.

  • Patent number: 4589234
    Abstract: An apparatus for the deburring or coating removal of workpieces which are subjected to direct heat exchange with a low temperature coolant, e.g. liquid nitrogen, has a transport path extending around a sling wheel to which a granular path medium is supplied via a hollow shaft which is cantilever journaled externally of the treatment chamber. The blast medium is fed to the sling wheel via a nonrotatable tube extending through the hollow shaft so that centrifugal force does not cause free flow media to adhere to the inner walls of the shaft and impede delivery to the sling wheel.

  • Patent number: 4516878
    Abstract: Tunnels are constructed by freezing soil and removing frozen soil between starting and end shafts of the tunnels. Tunnels are driven in an uncomplicated manner in rapidly changing soils without auxiliary construction means. A hole is bored in or near the planned axis of the intended tunnel between starting and end shafts. A soil freezing work pipe is inserted into the hole. The pipe is cooled by a cooling agent. The soil freezing work pipe continues to be cooled until an ice and frozen soil mass has formed around the work pipe, which frozen mass has a diameter which is larger than that of the planned tunnel. Frozen soil is subsequently excavated, leaving a frozen soil lining, which is immediately supported by a primary support lining or a permanent lining.
