Understanding Burner Management Systems
Critical Safety Function
A Burner Management System (BMS) is a safety system that supervises and controls the startup, operation, and shutdown of burners in boilers, heaters, and other combustion equipment. It ensures safe ignition, monitors flame presence, and provides emergency shutdown in case of unsafe conditions.
The BMS prevents explosions and equipment damage by verifying purge cycles, proving flame before allowing fuel flow, and immediately cutting fuel on flame failure.
Key BMS Functions
- ✓ Pre-Purge – Air purge before ignition to remove unburnt gases
- ✓ Pilot Ignition – Safe ignition of pilot burner
- ✓ Main Burner Ignition – Controlled main fuel admission
- ✓ Flame Monitoring – Continuous flame verification
- ✓ Safety Shut-Off – Immediate fuel cut on flame loss
- ✓ Post-Purge – Air purge after burner shutdown
- ✓ Interlock Monitoring – Air flow, pressure, temperature checks
- ✓ Valve Proving – Leak testing of safety valves
