Detect hot spots at 100°C before flame or smoke. Trusted solution for power plants, steel & mining in India
Infrared Heat Detector (IRD) for Coal Conveyors (Patol IRD 5450)
Early Fire Detection System for Coal Handling Plants in India
Protect your conveyor belts from fires, hot spots, and smouldering coal with the Infrared Heat Detector (IRD) – a proven solution for thermal hazard detection before flame formation.
Designed for Indian industrial conditions (dust, heat, vibration), this system ensures early warning, reduced downtime, and asset protection.
Why Infrared Detection for Coal Conveyors?
Coal conveyors are highly prone to:
• Friction-induced heating
• Belt misalignment
• Roller seizure
• Spontaneous combustion of coal
• Traditional systems detect only smoke or flame, which is often too late.
• The IRD detects “black heat” (infrared radiation) as low as ~100°C, before visible fire occurs.
How the IRD Works
• Monitors moving coal on conveyor belts
• Detects temperature rise using dual infrared sensors
• Triggers alarm / trip output before ignition
• Integrates with fire alarm panels or PLC systems
Key Features
• Detects embers & buried hot spots
• Dual IR sensors for high reliability
• Air purge system – prevents dust accumulation
• Fail-safe fault monitoring (air pressure & cable)
• Adjustable sensitivity & detection logic
• Alarm + Trip outputs for shutdown systems
• Compatible with 2-wire fire alarm loops
Applications in India
• Coal Handling Plants (CHP)
• Thermal Power Plants
• Steel Plants (Sinter / Coke conveyors)
• Cement Plants
• Ports & Bulk Material Handling
• Mining & Conveyor Systems

Frequently Asked Questions – Infrared Heat Detector (IRD)
Q1. What is an Infrared Heat Detector for conveyors? −
An Infrared Heat Detector (IRD) is an early fire detection system that identifies heat build-up in moving materials like coal before flames or smoke are visible
Q2. How is IRD better than smoke or flame detectors? +
Smoke and flame detectors react late. IRD detects heat at ~100°C, allowing preventive action before ignition.
Q3. Can IRD detect buried hot spots inside coal? +
Yes. IRD detects black body radiation, enabling detection of hidden or buried hot spots not visible externally.
Q4. Is this suitable for Indian coal handling plants? +
Yes. The system is designed for dusty, high-temperature environments, common in Indian CHPs, power plants, and ports.
Q5. What is the installation height of IRD? +
Typically 1 to 1.5 meters above the conveyor, covering up to 4.2 meters width.
Q6. Does it work in dusty environments? +
Yes. It includes an air purge system to prevent dust accumulation on the sensor.
Q7. Can it integrate with existing fire alarm systems? +
Yes. It provides alarm and trip outputs compatible with PLCs and fire panels.
Q8. What industries use IRD in India? +
Thermal Power Plants
Steel Plants
Cement Plants
Ports & Mining
