AM Monday: The Brain Behind the Burn

An RTO depends on more than burners, valves, and ceramic media. Its control system—consisting of the PLC, HMI, instrumentation, and field devices continuously manages combustion, airflow, valve sequencing, temperature, and safety functions. When automation begins to drift, system performance can decline long before a mechanical problem becomes apparent.

Minor issues such as sensor drift, communication faults, damaged wiring, outdated software, or recurring alarms can reduce combustion stability, increase fuel consumption, disrupt valve timing, and affect VOC destruction efficiency. Routine control system verification helps identify these conditions before they impact production or compliance.

Preventive Maintenance Tasks

• Verify calibration of temperature, pressure, flow, and process sensors.
• Test PLC inputs/outputs, HMI functions, burner permissive, safety interlocks, purge sequences, alarms, and emergency shutdown circuits.
• Inspect electrical panels, communication networks, wiring, and terminals for loose connections, corrosion, moisture intrusion, or signal loss.
• Review alarm history and operating trends to identify recurring faults, process deviations, or instrumentation drift.
• Verify controller backups, firmware compatibility, and configuration settings before system modifications or hardware replacement.

Operational Considerations

Reliable automation is essential for maintaining stable combustion, balanced airflow, accurate valve sequencing, and efficient heat recovery.

Even small control deviations can increase operating costs, reduce equipment reliability, and create unnecessary compliance risk.

Trend analysis is one of the most valuable predictive maintenance tools. Comparing current operating data with historical performance allows developing issues to be corrected before they become costly failures.

Ship & Shore Environmental Recommendation

Control system verification should be included with every scheduled preventive maintenance inspection. Ship & Shore Environmental recommends periodic evaluation of instrumentation, control logic, communications, safety circuits, and software integrity to maintain dependable operation and simplify troubleshooting.

Why It Matters

The control system is the operational brain of every RTO. Maintaining its accuracy helps protect VOC destruction efficiency, optimize fuel usage, extend equipment life, and support reliable environmental compliance.

A proactive controls maintenance program delivers safer operation, greater reliability, and more consistent performance throughout the life of the system.
