How to Perform Daily Inspection and Maintenance on Catalytic Combustion Equipment

Effective and uninterrupted operation of your catalytic combustion equipment is critical for ensuring compliant and efficient VOCs treatment. A proactive approach to daily checks and systematic maintenance is the most reliable strategy to prevent unexpected downtime, extend the system's lifespan, and maintain optimal destruction efficiency. This comprehensive guide outlines essential steps for the daily inspection and routine maintenance of your RCO system.

Why Daily Inspection and Maintenance are Non-Negotiable

Catalytic combustion systems are engineered for durability, but they operate in demanding environments. Regular monitoring is key to:

• Ensuring consistent VOCs treatment efficiency and compliance with environmental regulations.

• Identifying minor issues before they escalate into major, costly repairs.

• Protecting the valuable catalyst bed from premature poisoning or sintering.

• Maximizing energy efficiency and minimizing operational costs.

Daily Point Inspection Checklist for Catalytic Combustion Equipment

A quick but thorough daily visual and operational check can reveal early warning signs. Follow this list at the start of each operational shift:

1. Pre-Startup Visual Inspection

• System Integrity: Check for any visible signs of damage, corrosion, or leaks in ductwork, valves, and the combustion chamber housing.

• Safety Devices: Verify that pressure relief valves, flame arrestors, and other safety components are unobstructed and in place.

• Filter Status: Inspect the pre-filters for particulate loading. Excessive dust accumulation indicates it may be time for replacement.

2. Operational Parameter Monitoring

Once the system is running, record and compare the following key parameters against the baseline design values:

• Inlet & Outlet Temperature: Monitor the preheater and catalyst bed inlet/outlet temperatures. Significant deviations can indicate heat exchange issues or catalyst activity problems.

• System Pressure Drop: Note the differential pressure across the pre-filters and the catalyst bed. A rising pressure drop across filters signals clogging; across the catalyst bed, it may point to blockage or physical damage.

• Fan & Motor Operation: Listen for unusual vibrations or noises from the main exhaust and bypass fans. Check amperage readings.

• Control Panel: Confirm no alarm or fault indicators are active on the PLC or control system interface.

Scheduled Preventive Maintenance Plan

Beyond daily checks, a scheduled maintenance plan is vital. The following table outlines key tasks and recommended frequencies.

Focus Area: Catalyst Bed Health Management

The catalyst is the core of the catalytic combustion equipment. To protect your investment:

• Avoid Poisoning: Ensure upstream pre-treatment effectively removes catalyst poisons such as silicon, phosphorus, heavy metals, and excessive dust.

• Prevent Thermal Sintering: Strictly avoid exceeding the maximum allowable operating temperature. Ensure temperature sensors and safety interlocks are always functional.

• Regular Sampling: Annual catalyst sampling and lab analysis can quantify activity loss and guide replacement planning.

Troubleshooting Common Operational Issues

Here are some common problems and their potential causes:

• High Pressure Drop: Clogged pre-filters, blocked catalyst bed, or fan issue.

• Low Destruction Efficiency: Catalyst deactivation (poisoning/sintering), insufficient preheat temperature, or uneven flow distribution.

• Unstable Temperature Control: Faulty temperature sensor, malfunctioning control valve, or burner problem.
