    摘要: A method, device, and apparatus for tracing a conductive line and locating any concealed surveillance devices coupled to the line uses a signal generator to produce a test signal having a fundamental frequency which is coupled to the line under test. The test signal flowing through the line under test creates electromagnetic waves that propagate through the atmosphere away from the line. A portable locator probe is used to detect the radiated signal and thus the conductive line by detecting the magnitude of the radiated signal. As the locator probe is moved closer to the line, the amplitude of the detected signal increases. In addition, the portable locator probe detects harmonic signals radiated from nonlinear junctions coupled to the line at harmonic frequencies of the fundamental test signal. By examining the relative strengths of the second and third harmonic signals, a user can determine if the detected non-linear junction is being produced by a semiconductor or a corrosive/dissimilar metal type non-linear junction. A DC bias voltage can be used to improve the responses of any semiconductor based non-linear junctions. Any semiconductor junctions located with the probe are manually examined to determine the cause of the non-linear junction.

    摘要: A method of operating an oxygen transport membrane based reforming system employing one or more packs of thermally coupled panels of reformer tubes and oxygen transport membrane (“OTM”) reactors close to thermo-neutral point is provided. The method produces syngas by converting a hydrocarbon-containing feed, such as natural gas in the reformer tubes of a pack by endothermic steam reforming reactions. The heat required for endothermic reforming reactions is provided by exothermic oxidizing reactions occurring inside the OTM reactors of the pack. At a thermo-neutral point the heat released by exothermic reactions matches the heat required to support endothermic reactions and heat losses in the pack. The method modulates the flow rate of hydrocarbon-containing feed and/or steam-to-carbon ratio of the combined feed to the pack to maintain the surface temperature of oxygen transport membrane reactors below a target maximum temperature. The syngas product oxygen-to-carbon ratio is maintained within a desired target range such that the OTM based reforming system is operated close to thermo-neutral point.

    摘要: A method for fueling a solid oxide fuel cell stack is provided. The method includes passing a first portion of hydrocarbon fuel through a catalytic hydrocarbon reformer to generate a first reformate. The first reformate is passed through a hydrocarbon cracker to generate a second reformate such that a portion of any non-reformed hydrocarbon fuel in the first reformate is converted to methane. The second reformate is supplied to the fuel cell stack.

    摘要: An SOFC stack system including a reformer and fuel flow arrangement permitting optimized fuel reforming at all power load levels between 0% and 100%. A portion of the anode tail gas is combined with fresh air and fuel. The mixture is sent to a main reformer configured for endothermic reforming. Reformate is sent through a hydrocarbon cracker that breaks any hydrocarbons in the reformate into methane before the reformate enters the stack. At 100% load, there is no reforming in the main reformer; all of the fuel is internally reformed within the stack. At 0% load, all of the fuel is reformed in the main reformer. At loads between 0% and 100%, reforming is a mixture of endothermic reforming in the main reformer and internal reforming of methane within the stack. This strategy allows highest fuel processing efficiencies available through the full range of stack operation.
