1. Ensure Proper Operating Conditions

A burner performs best only when its supporting system is stable.

Gas Supply

• Maintain stable inlet gas pressure within the burner’s rated range

• Ensure upstream components (filter, regulator, solenoid valves) are clean and functional

• Use the correct gas type and calorific value as specified by the burner manufacturer

Combustion Air

• Provide clean, dry air with no blockage at the air inlet

• Check that fans and dampers operate smoothly

• Avoid negative pressure in the combustion chamber

2. Correct Ignition and Flame Control

Ignition problems are one of the most common burner failures.

• Inspect ignition electrodes for wear, cracking, or carbon buildup

• Keep correct electrode gap and position

• Verify reliable spark strength and ignition timing

• Clean and correctly position the flame detector (UV, ionization, or IR sensor)

3. Maintain Optimal Air–Fuel Ratio

Incorrect air–fuel ratio reduces efficiency and damages equipment.

• Adjust the burner for a stable blue flame (natural gas) or correct flame shape for your fuel

• Avoid:

  • Too much air → flame instability, heat loss

  • Too little air → CO formation, soot buildup

• Use a flue gas analyzer to confirm:

  • O₂

  • CO

  • NOx levels

4. Regular Cleaning and Inspection

Create a routine maintenance schedule.

Burner Components

• Clean burner head, nozzles, and mixing parts

• Remove dust, oil, and carbon deposits

• Inspect refractory and flame tube for cracks or deformation

Gas Train

• Check for gas leaks using approved leak detection methods

• Test solenoid valves for fast opening and tight closing

• Inspect flexible connections and seals

5. Check Safety Devices Frequently

Safety systems must work 100% of the time.

• Test:

  • Gas pressure switches (high/low)

  • Air pressure switches

  • Safety shut-off valves

• Verify emergency shut-down response

• Never bypass safety interlocks

6. Electrical and Control System Care

Many burner failures come from electrical issues.

• Tighten all electrical terminals periodically

• Protect control panels from moisture and vibration

• Check grounding and shielding to avoid signal interference

• Update burner controller parameters only by trained personnel

7. Follow a Preventive Maintenance Plan

A simple example schedule:

8. Use Qualified Operation and Spare Parts

• Train operators on normal flame behavior and alarm causes

• Use original or approved spare parts

• Keep critical spares: electrodes, flame sensors, seals

9. Monitor Performance Indicators

Watch for early warning signs:

• Increased gas consumption

• Flame instability or frequent shutdowns

• Rising CO or NOx emissions

• Uneven heating

These usually indicate air–fuel imbalance or component wear.
