  • Patent number: 9127234
    Abstract: A particulate coke composition including expandable coke is capable of removing deposits from rotating parts of a gas turbine engine while under full fire or idle speed. The coke composition may be introduced directly into the combustion chamber (combustor) of the gas turbine or, alternatively, anywhere in the fuel stream, water washing system, or the combustion air system. By kinetic impact with the deposits on blades and vanes, the deposits will be dislodged and will thereby restore the gas turbine to rated power output. If introduced into the compressor section, the coke particles impinge on those metal surfaces, cleaning them prior to entering the hot gas section where the process is repeated.

  • Patent number: 8977746
    Abstract: A network security device may gather a large amount of metadata pertaining to the connections being managed thereby. A refinement module may filter and/or aggregate the connection metadata. The metadata may be refined on the network security device. The refined metadata may be provided for display on a terminal. The refined metadata may include a subset of the larger connection metadata, which may reduce the overhead required to display and/or transmit monitoring information to the terminal device. The refined metadata may comprise connection groups, which may be formed based on aggregation criteria, such as connection source, destination, application, security policy, protocol, port, and/or the like. The connection groups may be ranked in accordance with ranking criteria.

  • Patent number: 8426347
    Abstract: The present invention describes a nanoparticle size composition comprising at least one overbase complex of a magnesium salt and an associated organic boron complex. The present compound is an improvement over previous processes due to less complicated processing requirements and the high concentration of both magnesium and boron that results.

  • Patent number: 7185663
    Abstract: Methods and compositions for on-line cleaning of internal surfaces of selected sections of a hydrocarbon fuel burning gas turbine and associated heat recovery equipment, during operation. Cleaning solutions containing graphite and/or molybdenum-based particles and oil soluble corrosion inhibitors, aromatic solvents, and surfactants are selectively introduced directly into the combustion chamber (combustor) of the gas turbine, into the fuel stream, water washing system, or the combustion air system (hot gas path). The cleaning process dislodges unwanted ash deposit buildup and, thereby restores the gas turbine to rated power. When introduced into the compressor section, the particles impinge on the metal surfaces, cleaning them prior to entering the hot gas section where the process may be repeated. They may also be carried through the exhaust to additionally clean attendant heat recovery equipment, if present.
