How do you identify bridging in a fuel storage system?

Bridging in a fuel storage system, such as a silo or hopper, occurs when the fuel forms an arch or obstruction that prevents it from flowing freely due to interlocking of particles, moisture, or compaction. Several indicators can help identify bridging. First, a sudden drop in fuel feed rate is a primary symptom. If the fuel feeding system is operating normally, but the amount of fuel being delivered decreases significantly or stops altogether, bridging is likely occurring. Second, visual inspection of the fuel storage system, if possible, can reveal the presence of a bridge. This may involve looking into the silo or hopper through inspection ports or using cameras to observe the fuel level. Third, changes in the sound of the fuel handling system can indicate bridging. A hollow or muffled sound may suggest that the fuel is not flowing freely. Fourth, monitoring the fuel level in the storage system provides valuable information. If the fuel level remains constant despite the fuel feeding system operating, this suggests that a bridge is preventing the fuel from flowing downwards. Fifth, an increase in the power consumption of the fuel feeding system may indicate bridging. If the feeders are working harder to extract fuel, it suggests that there is an obstruction in the fuel flow path. Sixth, use level sensors. Discrepancies between level sensors at different heights can also be used to infer the location of the fuel in the silo. Seventh, using acoustic sensors to 'listen' to the flow profile and analyze for disturbances. By observing these indicators, bridging can be identified and addressed promptly to prevent disruptions in the fuel supply.
