3D Radar for Coal Silos: Preventing Summer Caking Risks

Wet coal in silos causes inaccurate inventory, wall clinging, and structural stress. The RETTAR 3DPro 2300 Radar Scanner provides precise 3D real-time bulk solids monitoring, preventing blockages and ensuring safe, accurate fuel management.
Peak summer electricity demands require power plants to maintain maximum fuel reserves. However, high seasonal humidity and heavy rainstorms make stored coal wet and cohesive, causing material to stick to vessel walls and form hidden internal cavities. Deploying an advanced system, such as the RETTAR 3DPro 2300 Radar Scanner, addresses these measurement errors by replacing single-point estimations with continuous radar tracking—ensuring reliable bulk inventory tracking, preventing structural wall damage, and enabling safe fuel management.

Seasonal Hazards vs. 3D Real-Time Bulk Monitoring Solutions

Summer humidity and heavy rainfall create severe material handling challenges in power generation plants. Wet coal becomes highly cohesive, causing it to cling to vessel walls and form dangerous hidden arches or cavities. Traditional meters often measure a single high spot, mistaking a half-empty vessel for a full one and causing critical fuel supply disruptions. Furthermore, irregular coal surfaces create uneven lateral pressure against vessel walls, leading to dangerous structural strain.
To mitigate these operational hazards, 3D sensing directly resolves the primary risks associated with coal storage:
  • Mitigating Coal Wall Clinging: Clinging coal creates hidden hollow spaces, material bridging, and false high-level readings that compromise fuel management. Through 3D Surface Mapping, the system continuously scans the entire interior area, exposing true internal cavities and material build-up before severe blockages occur.
  • Balancing Asymmetrical Loading: Uneven material distribution exerts asymmetric lateral pressure on vessel walls, increasing the risk of structural fatigue and cracking. 3D Real-Time Bulk Monitoring detects uneven pile formations early, allowing operators to balance wall stress during material draw-down.
  • Eliminating Manual Safety Risks: Traditional manual auditing exposes maintenance personnel to hazardous high climbs, airborne coal dust, and confined-space environments. Non-Contact Automated Scanning provides continuous remote telemetry while keeping maintenance crews safely on the ground.

80GHz 3D Sensing Engineering Drives Precise Bulk Inventory Accuracy

To maintain measurement accuracy through heavy airborne dust and moisture, modern non-contact instruments rely on an 80GHz 3D sensing architecture. Utilizing an 80GHz 3D radar transmitter, the system emits narrow high-frequency signals that penetrate dusty environments without signal loss.
Engineered specifically for harsh silo environments, the 3DPro 2300 Radar Scanner performs continuous multi-point sweeps with full 360° imaging, capturing 16,200 scanning points across the inner space to generate accurate spatial coordinates for live 3D Surface Mapping. This continuous high-density scanning delivers an exceptional ±0.5% FS...±2% FS volumetric accuracy, revealing exact surface contours, coal build-up, and center funnels without requiring risky manual inspections or disruptive plant shutdowns.
Designed for seamless deployment, the 3DPro 2300 requires only a 190 mm mounting opening for flange installation—preserving the structural integrity of the vessel roof—while featuring an IP68 enclosure rating for long-term operational reliability.

3D Volumetric Scanner Integration Delivers Complete Data Transparency

Upgrading to a field-proven 3D volumetric scanner transforms raw physical measurements into verifiable operational insights across the facility:
  • Complete Silo Transparency: Control room operators gain clear visual maps of internal coal distribution, identifying wall clinging early to prevent structural blockages.
  • Enterprise Data Transparency: Verified inventory metrics stream directly via standard industrial protocols (such as OPC UA, Modbus TCP, and MQTT) into plant PLC, DCS, MES, and central ERP systems, establishing automated stock accounting.
  • Predictive Fuel Logistics: Real-time volume updates empower procurement teams to schedule fuel deliveries accurately and eliminate emergency plant stoppages.
