[0043] FIG. 2 illustrates an exemplary representation of the proposed device for assessing refractory erosion and disbonding in an industrial equipment, in accordance with an embodiment of the present disclosure.
[0044] Illustrated in Fig. 2 is a representation of the device 100.
[0045] In an embodiment, the device 100 includes the LiDAR scanner 104 that serves as the core scanning unit, emitting laser beams to capture high-resolution 3D topography data of the refractory lining inside the industrial equipment. The LiDAR scanner 104 measures the remaining thickness of the refractory material, detecting erosion and disbonding with millimeter precision.
[0046] In an embodiment, a top hook 202 of the deployment unit 106 of the device 100 is mounted at an uppermost section of the equipment and acts as an anchor for the pulley and rope system, enabling the controlled vertical movement of the LiDAR scanner 104 within the vessel.

The pneumatic cylinders 208 ensure that the lower arm scanning unit 110 can be precisely positioned to scan targeted sections without manual intervention.
[0048] In an embodiment, to ensure full 360° coverage of the internal surfaces of the equipment, the lower arm scanning unit 110is equipped with a DC motor 210, which drives a gear assembly that enables continuous rotation around its axis. This DC motor-driven rotation allows the LiDAR scanner 104 to map the entire circumference of the vessel, ensuring that no critical data points are missed.
[0049] In an embodiment, the device 100 provides a fully automated, non-destructive refractory inspection method, eliminating the risks associated with human entry into hazardous environments. The LiDAR scanner 104, in conjunction with the lower arm scanning unit 110 and the centering legs 204, ensures stable and precise scanning at multiple elevations within the equipment. The three centering legs 204 are configured to adjust automatically to a diameter of the equipment at each scan location to enable execution of multiple scans at varying elevations. The top hook 202 and the pulley and rope system enable smooth deployment, while the pneumatic cylinders 208 ensure stability and adaptability to different vessel diameters. The adjustability of the lower arm scanning unit 110 extends scanning capabilities to hard-to-reach areas, while the DC motor-driven rotation guarantees full 360° coverage. This combination of advanced scanning, automated deployment, and real-time data processing enhances inspection accuracy, reduces downtime, and supports predictive maintenance in high-temperature industrial equipment such as kilns, risers, and cyclones.
[0050] FIG. 3 illustrates an exemplary representation of the proposed device with a magnified representation of a ring arrangement unit of the device, in accordance with an embodiment of the present disclosure.
[0051] Illustrated in Fig. 3 is a representation 300 of the ring arrangement unit 114 of the device 100.
[0052] In an embodiment, the LiDAR scanner 104 is the core sensing component of the device 100, responsible for capturing high-resolution 3D topography data of refractory linings inside the industrial equipment. The LiDAR scanner 104 emits laser beams that reflect off the surface of the refractory material, allowing the device 100 to generate detailed digital elevation models for assessing erosion and disbonding. The LiDAR scanner 104 operates in real-time, continuously mapping the interior of vessels such as kilns, risers, and cyclones with millimeter-level precision.
[0053] In an embodiment, to ensure efficient control over its operation, the device 100 incorporates the ring arrangement unit 114, which is placed around the LiDAR scanner 104 to manage its activation and deactivation. The ring arrangement unit 114 serves as a mechanical switch, allowing the operator to engage or disengage the scanner as needed. The ring arrangement unit 114 is actuated by pneumatic pistons 302, which provide precise movement for controlling the operational state of the LiDAR scanner 104. When the device 100 needs to begin scanning, the pneumatic pistons 302 engage the ring arrangement 114, allowing the LiDAR scanner 104 to activate and commence data collection. Conversely, when scanning is completed or if adjustments are required, the pneumatic pistons 302 disengage the ring arrangement unit 114, deactivating the LiDAR scanner 104.
[0054] In an embodiment, the automated activation mechanism ensures that the LiDAR scanner 104 only operates when necessary, optimizing energy efficiency and component longevity.

The 360° rotation of the lower arm scanning unit 110 ensures that even the most challenging areas of the equipment are fully scanned, resulting in comprehensive 3D data for accurate erosion assessment.
[0057] FIG. 4 illustrates an exemplary representation of a top view of the proposed device for assessing refractory erosion and disbonding in an industrial equipment, in accordance with an embodiment of the present disclosure.
[0058] Illustrated in Fig. 4 is a representation 400 of a top view of the device 100 in which the centering legs 204 and the pneumatic cylinder 206 are visible.
[0059] In an embodiment, the three centering legs 204 play a crucial role in maintaining the stability and alignment of the LiDAR scanner 104 within the industrial equipment during the scanning process. The three centering legs 204 extend outward to brace against the inner walls of the vessel, ensuring that the LiDAR scanner 104 remains centered and steady at different scanning elevations. By preventing unwanted movement, the centering legs 204 help eliminate vibration-induced errors, leading to more accurate 3D mapping of the refractory surface.
[0060] In an embodiment, each of the three centering legs 204 is adjustable, allowing the device 100 to adapt to various diameters of industrial vessels such as kilns, risers, and cyclones. The pair of pneumatic cylinders 208 controls the movement of the lower arm scanning unit 110, which is responsible for scanning obstructed or hard-to-reach areas. The pair of pneumatic cylinders 208 allows the lower arm scanning unit 110 to tilt dynamically between 0° and 90°, providing flexibility in adjusting the scanning angle. The precise pneumatic control ensures smooth and controlled movement, reducing the risk of mechanical stress or misalignment.
[0061] In an embodiment, the pair of pneumatic cylinders 208 helps in fine-tuning the scanning approach, ensuring that even complex surface geometries are accurately captured. Together, the centering legs 204 and the pair of pneumatic cylinders 208 work in synchronization to optimize scanner positioning, maintain structural stability, and enhance data accuracy during refractory inspection. Their integration ensures that the device 100 operates autonomously and reliably, minimizing human intervention and improving inspection efficiency.
[0062] FIG. 5 illustrates an exemplary flowchart representation of the proposed method for assessing refractory erosion and disbonding in an industrial equipment, in accordance with an embodiment of the present disclosure.
[0063] Illustrated in Fig. 5 is a flowchart representation of the method 500 of assessing refractory erosion and disbonding in the industrial equipment. The method 500 begins with deploying 502, by the processor 102, the LiDAR scanner 104 into the equipment. The method 500 proceeds with capturing 504, by the processor 102, high-resolution three-dimensional profiles of a refractory lining of the equipment by performing scans at varying elevations. The method 500 proceeds with analysing 506, by the processor 102, the captured profiles to identify areas of erosion and disbonding with reference to design drawings or historical datasets. The method 500 ends with generating 508, by the processor 102, a color-coded map and a tabulated report comprising an extent and location of refractory degradation.
[0064] In an embodiment, the method 500 begins with the deployment of the LiDAR scanner 104 into the industrial equipment, ensuring precise positioning using the pulley and rope system. The top hook 202 secures the deployment unit 106, allowing controlled vertical movement of the scanner inside the vessel. As the LiDAR scanner 104 is lowered, the three centering legs 204 extend outward to brace against the inner walls of the equipment, ensuring stability and alignment during data collection.
[0065] In an embodiment, the LiDAR scanner 104 emits laser beams to capture high-resolution three-dimensional profiles of the refractory lining. Multiple scans are performed at varying elevations to generate a comprehensive digital model of the interior. The lower arm scanning unit 110, controlled by the pair of pneumatic cylinders 208, adjusts dynamically between 0° and 90° to scan hard-to-reach areas. The 360° rotation mechanism, powered by the DC motor 210 and the gear assembly 304, ensures full coverage of the refractory surface.
[0066] Once scanning is complete, the captured 3D point cloud data is processed to create a detailed topographical representation of the refractory lining. The device 100 analyses the scanned profiles, identifying regions where erosion and disbonding have occurred. To enhance accuracy, the scanned data is compared with design drawings or historical datasets, highlighting deviations from the original refractory thickness. Advanced algorithmic processing identifies critical wear zones, predicting potential refractory failures. A color-coded map is then generated, visually representing the extent and severity of degradation across the scanned area. Areas with minimal wear appear in green, while moderate and severe erosion are marked in yellow and red, respectively. In parallel, a tabulated report is produced, detailing the precise location, depth, and extent of refractory degradation. The report provides valuable insights for proactive maintenance planning, allowing plant operators to schedule repairs before significant damage occurs. The automated inspection process eliminates the need for manual entry, significantly enhancing operator safety. The non-contact LiDAR-based approach ensures greater accuracy and repeatability compared to conventional methods.
[0067] In an embodiment, the remote operation capability of the device 100 enables real-time data transmission to maintenance teams, facilitating quick decision-making. The ring arrangement unit 114, actuated by the set of pneumatic pistons 302, controls the activation and deactivation of the LiDAR scanner 104 as needed. By automating the scanning process, the method 500 minimizes human error and improves overall inspection efficiency. The collected data also contributes to long-term condition monitoring, helping industries optimize refractory material lifespan. With a fully digitalized inspection workflow, plant operators can reduce downtime, enhance equipment reliability, and improve cost-effectiveness. The integration of LiDAR scanning with Augmented Reality SCAN (ARSCAN) technology ensures precise, repeatable, and high-resolution refractory assessments.
[0068] In an embodiment, the processor 102 is configured to enable historic comparison and monitoring of refractory material degradation, facilitating efficient maintenance planning and extension of the operational life of the equipment. The processor 102 plays a crucial role in analysing and comparing historical refractory data with newly acquired LiDAR scan results to monitor material degradation over time. By identifying patterns of erosion and disbonding, the device 100 enables maintenance teams to detect early signs of wear and schedule preventive repairs before critical failures occur. The device 100 automatically processes the scanned data, overlaying it on previous inspection records or design specifications to highlight areas with significant changes. This predictive maintenance approach helps in optimizing repair schedules, reducing unexpected downtime, and minimizing operational costs. As a result, the device 100 effectively contributes to extending the operational life of industrial equipment by ensuring timely and data-driven maintenance decisions.
[0069] In an embodiment, industrial equipment such as cyclones, risers, and kilns operate under extreme conditions, requiring refractory linings to withstand high temperatures and intense processes while providing insulation. Over time, these harsh conditions cause refractory degradation, leading to erosion, disbonding, and material damage, which affect vessel performance, safety, and efficiency. Various factors, including operational age, temperature fluctuations, airflow, catalyst type, and material properties, influence the rate of refractory wear. The device 100 enables operators to monitor and quantify refractory degradation with each turnaround, ensuring accurate assessment of maintenance needs. The device 100 is configured to inspect equipment ranging from 500 mm to 30,000 mm in diameter, covering a broad range of industrial applications. The LiDAR scanner 104 operates at temperatures up to 50°C, ensuring functionality in challenging environments. The LiDAR scanner 104 features a tilt angle adjustable from 0° to 90°, enabling comprehensive surface coverage. Further, the device 100 provides a continuous 360° rotation, ensuring full scanning coverage of the refractory lining. By offering detailed 3D mapping and analysis, the device 100 helps operators make informed maintenance decisions, reducing downtime and operational risks. This automated and precise solution enhances safety, efficiency, and the overall lifespan of industrial equipment.
[0070] A use case of the device 100 is described herein. In a cement factory, the refractory lining inside a rotary kiln is subject to extreme temperatures and constant mechanical stress, leading to erosion and disbonding over time. Traditional inspection methods require manual entry, exposing workers to high-temperature environments and potential safety hazards. To overcome these challenges, the device 100 is deployed to inspect the refractory condition of the kiln without requiring human entry. The device 100 is positioned at the access point of the kiln, and the LiDAR scanner 104 is lowered inside using the pulley and rope mechanism for precise deployment. The three centering legs 204 extend outward, stabilizing the LiDAR scanner 104 within the cylindrical structure of the kiln to eliminate vibrations. As the LiDAR scanner 104 moves downward, the LiDAR scanner 104 performs 3D scans at varying elevations, generating a high-resolution topographical profile of the refractory lining. The lower arm scanning unit 110, controlled by the pneumatic cylinders 208, dynamically adjusts its angle between 0° and 90°, ensuring that hidden or obstructed areas are fully captured. The DC motor 210 and the gear assembly 304 allow for 360° rotation, covering the entire inner surface of the kiln. The scanned data is processed to detect refractory wear, and deviations are identified by comparing the data against historical thickness records or design drawings. A color-coded map is generated, where green areas indicate minimal wear, while yellow and red regions highlight significant erosion. A tabulated report provides detailed information on erosion depth, location, and affected zones, enabling maintenance teams to prioritize repairs. The device 100 transmits real-time data to the operators, ensuring timely and informed decision-making. By eliminating the need for manual inspections, the device 100 enhances safety, accuracy, and efficiency while reducing kiln downtime. With predictive maintenance capabilities, the cement factory can extend the lifespan of refractory materials and optimize operational costs. The automated and repeatable nature of the inspection ensures consistent quality control and improves plant reliability.
