Thermal Monitoring for Biomass & Wood Chip Storage 

Preventing fires before they start across forestry, processing, transport, and energy production. 

Woodchip, pellets, bark, and sawdust are now stored at large scale across the UK, in timber yards, sawmills, CHP plants, district heating facilities, and major ports. These materials carry a well-known fire risk: spontaneous combustion developing deep inside stockpiles with no visible warning. 

Thermascan provides continuous, early-warning thermal monitoring using FLIR fixed cameras, installed and configured by our in-house thermographers. The system shows hidden heat build-up long before combustion temperature is reached, giving operators the time they need to intervene safely. 

The Fire Risk in Biomass & Wood Storage 

Spontaneous combustion is driven by microbial activity and oxidation inside stored wood fuels. Heat accumulates slowly at first, then accelerates rapidly, often between manual inspections. 

Common consequences across the sector include: 

  • Timber yards & sawmills: production disruption, stock loss, equipment damage 

  • Biomass CHP plants: unplanned shutdowns, heat supply interruptions, costly cleanup 

  • Ports & logistics operators: cargo rejection, vessel fire risk, operational delays 

  • District heating & municipal energy sites: supply continuity risks, regulatory pressure 

By the time smoke or steam is visible, the hotspot is already well-developed and far harder to control. This is why continuous, automated monitoring is increasingly expected by insurers and regulatory bodies. 

How Thermascan Monitoring Works 

Thermascan installs fixed FLIR thermal cameras at locations tailored to your site layout, fuel types, and storage method. The system operates continuously, without relying on staff availability or manual checks. 

How detection happens: 

  • Continuous scanning of stockpiles, bays, silos, and storage areas 

  • Automated hotspot detection at 50–60°C, well below combustion temperature 

  • Instant alerts via SMS, email, and/or integration with existing alarm systems 

  • A thermal image is automatically captured to show the exact location of the hotspot 

Temperature thresholds are set during commissioning based on your specific fuel, storage volume, and operational risk profile. 

What Thermal Imaging Delivers

Reliable Early Detection Provides a real intervention window, hours, not minutes, before temperatures reach dangerous levels.
Continuous 24/7 Monitoring Automated scanning independent of staff workload, shift patterns, or manual inspection routines.
Clear Documentation Every alert includes a thermal image and temperature data, creating a record for operational oversight and insurance compliance.
Flexible Integration Works alongside site alarms, monitoring software, and existing safety systems.
Remote Visibility Operations teams and managers can access temperature data and alerts securely.

FAQs

  • Stored wood fuels generate heat through natural microbial and oxidation processes. In large piles the heat cannot escape, causing internal hotspots that are not visible from the outside. 

  • By continuously monitoring pile surfaces with fixed FLIR thermal cameras, the system identifies rising temperatures long before they become dangerous, giving operators time to intervene safely. 

  • It reduces reliance on manual checks by providing continuous coverage, helping detect developments that would otherwise occur between scheduled inspections. 

  • Yes. The FLIR cameras used by Thermascan are suited to exposed sites such as yards, terminals, and port storage areas. 

  • Alerts are issued automatically as soon as a preset temperature threshold is exceeded and include a thermal image showing the hotspot’s location. 

  • Yes. Multiple fixed cameras can be positioned across large sites to provide full coverage of bays, silos, open piles or conveyor-fed fuel stores.
