Symptom & Diagnostic Guide
Diagnostic symptoms observed on plant floors, root causes, and recommended replacement spares.
| Observed Symptom | Root Cause & Check | Corrective Action & Replacement Spares |
|---|---|---|
Burner starts pre-purge but locks out immediately when ignition spark begins | Cracked ceramic insulator on ignition electrode causing spark shorting to blast tube, or faulty ignition transformer. | Check electrode ceramics for hairline cracks; replace electrode pair; test transformer spark across 4mm air gap. Spares: Danfoss EBI4 transformer / pair of ceramic ignition electrodes |
Burner ignites flame, runs for 3 seconds, then trips into lockout | Dirty or degraded photocell failing to detect flame lux, or incorrect flame tube alignment. | Clean photocell lens; verify sensor resistance drops below 5 kOhm under active flame; replace sensor if unresponsive. Spares: Danfoss LD/LDS photocell or Siemens QRB1 sensor |
Fuel pump pressure drops or fluctuates wildly during firing | Clogged internal pump strainer, air ingress in suction pipe, or worn pump gear set from unheated HFO. | Clean pump strainer; verify suction line vacuum (< 0.4 bar); check pump pressure regulator diaphragm. Spares: Suntec AN67 / AS47 / J6 fuel pump |
Identify observed symptom to isolate cause and match the replacement component.
Recommended Preventive Maintenance Checklist
Operational inspection intervals designed to prevent unplanned line shutdowns.
| Maintenance Task | Recommended Interval | Engineering Focus & Verification |
|---|---|---|
| Nozzle Inspection & Replacement | Quarterly or 1,500 run hours | Inspect nozzle orifice for fuel varnish, carbon buildup, and erosion; replace with exact GPH rating and spray angle. |
| Photocell Lens Cleaning | Monthly | Wipe soot and oil vapor film off optical photocell sensor lenses to prevent false flame failure trips. |
| Fuel Pump Strainer & Pre-filter Service | Bi-weekly for HFO; monthly for Diesel | Clean internal pump wire mesh strainer and upstream duplex basket filter to protect pump gear teeth. |
| Ignition Electrode Gap Calibration | Quarterly | Verify spark gap (3–4mm) and setback from oil nozzle spray envelope to prevent electrode oil soaking. |
| Combustion Air Damper & Diffuser Cleaning | Bi-annual | Remove combustion head, clean diffuser disc vane slots of carbon crust, check air damper servomotor linkage. |
Regular servicing schedule recommended for continuous plant duty in Kenya.
Before Ordering a Replacement Spare
Before replacing parts on Monoblock & Dual-Fuel Industrial Burners, recording the right physical parameters prevents incorrect orders and unnecessary downtime. Manufacturer designs and tolerances vary—always verify these key details:
1. Nameplate & Model
- • Equipment OEM, complete model number & serial code
- • Frame size, operating speed (RPM), and direction of rotation
- • Voltage, full-load amps, or fuel/steam pressure rating
2. Critical Dimensions
- • Calliper shaft diameter (at seal/bearing seat, not worn area)
- • Flange PCD, hole diameter, bolt quantity, and face type
- • Port connection threads: verify BSPP parallel vs BSPT tapered vs NPT
3. What to Send STARNEX
- • Clear photograph of the machine nameplate
- • Photos of the worn component and its stamped markings
- • Fluid/medium handled, temperature, and operating pressure
When the exact part number or specification is unclear
If the nameplate is painted over, corroded, or missing entirely, do not guess or attempt to modify an ill-fitting part. Take clear photos of the part alongside a vernier caliper or tape measure, note the shaft diameter, keyway dimensions, or port thread sizes, and send them to our technical team via WhatsApp or email. Our desk cross-references physical measurements against OEM catalogs daily.

Related Maintenance & Diagnostic Procedures
Industrial Burner Flame Failure, Photocell Faults & Sequence Lockout Diagnostics
Industrial burners on steam boilers, thermal oil heaters, asphalt drum mixers, and tea dryers rely on automatic sequence controllers (such as Siemens LFL, LMO, or Riello 530SE) to safely supervise pre-purge, ignition sparking, fuel valve opening, and continuous flame presence. A lockout condition trips the red indicator lamp whenever safety parameters are violated. Rapid troubleshooting requires isolating whether the failure occurs during pre-purge air proving, ignition spark generation, fuel atomization, or optical flame detection.
Frequently Asked Questions: Monoblock & Dual-Fuel Industrial Burners Spares
The spray angle (typically 45°, 60°, or 80°) is determined by your boiler combustion chamber dimensions. Long, narrow fire tubes require narrower spray angles (45° or 60°) to prevent flame impingement on the tube walls, while shorter, wider chambers use 80° nozzles for complete air-fuel mixing.
No, the AN and AS series have different internal solenoid valve setups and flow capacities. AN series pumps have an external bypass and cut-off, while AS series incorporate a built-in solenoid blocking valve. Always match the exact model code, rotation direction (clockwise/counter-clockwise), and shaft diameter.
Heavy soot is caused by incomplete combustion, typically resulting from worn atomizing nozzle orifices, insufficient fuel oil pressure (< 10 bar), cold fuel oil viscosity (HFO below 110°C), or restricted combustion air intake.
