Disclosed is a sensing system to evaluate and monitor the status of a material forming part of a refractory furnace, integrating an antenna and a grating structure that might be part of the furnace. The system is operative to identify flaws and measure the erosion profile and thickness of different materials, including refractory materials of an industrial furnace, using radiofrequency signals. The system is designed to integrate the antenna with a grating adjacent to an external furnace wall to improve the overall performance of the sensing system as compared to that of the antenna alone during an inspection of the furnace, even in regions of difficult access. Furthermore, the system comprises a mechanism to physically attach the antenna to the furnace grating or to modify the grating configuration around the antenna to improve the system performance for better estimating the remaining operational life and maintenance plan of the furnace.

Antenna-grating coupled sensing system for clutter reduction during evaluation of a status of a material

Disclosed is an improved device and method to evaluate the status of a material by scanning an area that overlaps a region of the material under evaluation. The device and method are operative to identify a leakage of a first material into a second material, such as a molten material surrounded by a refractory material, to measure the thickness of the second material, using electromagnetic waves, and to generate images. The device is designed to reduce a plurality of reflections associated with the propagation of electromagnetic waves launched into the material under evaluation, by a sufficient extent so as to enable detection of electromagnetic waves of interest reflected from remote discontinuities present in between the device and the enclosed material. Furthermore, the device can be configured to scan areas of interest in either a portable or fixed configuration, manually in a standalone mode or as part of an automated system.

Disclosed is a system to evaluate and monitor the status of a material forming part of an asset, such as a refractory furnace. The system is operative to identify flaws and measure the erosion profile and thickness of different materials, including refractory materials of an industrial furnace, using radiofrequency signals. The system is designed to integrate software with a plurality of sensors and additional hardware to collect data during an inspection of the furnace, even in regions of difficult access. Furthermore, the system comprises a software management subsystem configured to implement signal processing techniques to process the data collected and generate reports to visualize the status, estimate the remaining operational life, and determine the level of penetration of molten material into the surrounding layers of the furnace. Moreover, the system's software enables a user to monitor the status of the furnace both locally and remotely.

Asset life optimization and monitoring system

Disclosed is an improved system and method to evaluate the status of a material. The system and method are operative to identify flaws and measure the erosion profile and thickness of different materials, including refractory materials, using electromagnetic waves. The system is designed to reduce a plurality of reflections, associated with the propagation of electromagnetic waves launched into the material under evaluation, by a sufficient extent so as to enable detection of electromagnetic waves of interest reflected from remote discontinuities of the material. Furthermore, the system and method utilize a configuration and signal processing techniques that reduce clutter and enable the isolation of electromagnetic waves of interest. Moreover, the launcher is impedance matched to the material under evaluation, and the feeding mechanism is designed to mitigate multiple reflection effects to further suppress clutter.

Material erosion monitoring system and method

Disclosed is an improved system and method to treat an edge of a material for determining a property of such material through measurements of electromagnetic waves. The system and method are operative to mitigate the adverse effects caused by the interaction between an electromagnetic wave and an edge of a sample of a material under test. The system and method define a configuration to block and significantly attenuate the propagation of electromagnetic waves that may reach an edge of the sample being evaluated. This configuration reduces the undesired effects caused by edge-diffraction that may interfere with the measurement of desired electromagnetic waves for material evaluation. As a result, a property of a material under test can be measured more accurately, especially near the edges of such material. In addition, the system and method enable the evaluation of a small-size sample of a material.

Edge treatment system and method for evaluating a material

Disclosed is an antenna feeding system and method to optimize the design of the feeding system to feed an antenna made of a resistive sheet. The system and method are operative to design a topology of the antenna feeding system to adapt to a topology of the resistive sheet antenna to mitigate the adverse effects caused by the inherent losses of resistive sheets while operating as antennas. The system is designed to reduce a convergence of radiofrequency currents that may create a localized high density current concentration, such as 'hot spots' and 'pinch points,' on the resistive sheet, by a sufficient extent so as to prevent power losses that substantially decrease the radiation efficiency of the antenna as compared with feeding systems designed using traditional design techniques.
