摘要： The present invention provides for the use of a metal-organic framework (MOF) in removing particular chemical species or compounds, in particular oxy-anions of iodate, from a liquid or liquid stream. In some embodiments, the MOF is a Zr-based MOF, such as NU-1000 or MOF-808. The Zr-based MOF, including NU-1000 or MOF-808 can be used to remove these oxy-anions from various liquid streams or liquids in industrial processes such as a nuclear and fossil fuel power plants.

摘要： A method for detecting blowout precursors in at least one gas turbine combustor comprising: receiving combustion dynamics acoustic data measured by an acoustic measuring device associated with the combustor in real time; performing wavelet analysis on the acoustic data using simplified Mexican Hat wavelet transform analysis; and determining the existence of a blowout precursor based at least in part on the wavelet analysis. Provided also is a system and a non-transitory computer readable medium configured to perform the method.

摘要： An in-situ incremental reheating system configured to increase steam temperature and thermodynamic efficiencies of a steam turbine is disclosed. The system includes a pump; a radiant heater; piping inter-connecting the pump, radiant heater and steam turbine to create a flow circuit; and a heat transfer material configured to flow through the flow circuit and transfer heat directly to steam used in the steam turbine. The pump moves the heat transfer material through the flow circuit and the radiant heater regenerates the heat transfer material after the heat transfer material transfers heat to the steam.

摘要： The invention provides various designs of an apparatus and method for attemperating a gas stream temperature. The apparatus of the present invention provides a body through which a gas stream passes that permits, as desired, a second gas, such as gas outside of the gas duct or such as ambient air, to be added to the main gas stream to attemperate the temperature of the main gas stream. The body or device may be referred to as a variable eductor having a plurality of openings through which a second gas may pass into the main gas stream. The openings may be opened or closed, and the variable eductor provides control over which openings and the degree to which each opening is opened. In some designs the variable eductor is inserted between two portions of a gas duct. The variable eductor has widespread application, such as downstream of a gas turbine to attemperate the exhaust gas temperature during startup.

摘要： A method of replacing pipe-type power cables is disclosed. The method includes the steps of using a pipe cutting rod to burst existing pipe; using an expander to expand soil surrounding the existing pipe to create a path for a new conduit or pipe; pulling the new conduit or pipe into the path created by the expander; and pulling new cables into the conduit or pipe.

摘要： A sensor and method for identifying a downed power transmission conductor or structure is disclosed. The method includes the steps of securing a sensor to a power transmission conductor or structure, using the sensor to measure inclination of the power transmission conductor or structure, comparing the measured inclination to a set threshold, and alerting a utility if the measured inclination exceeds the set threshold.
