Troubleshooting
Likely causes
What to check
Compare current firing rate, feedwater temperature and steam pressure against commissioning data. Check fuel flow and combustion analyser readings.
When to call us
If pressure doesn't recover after cleaning the sight glass and confirming feedwater valve operation, book a combustion tune-up and tube inspection — scaling is the most common cause.
Likely causes
What to check
Check gas supply pressure at the regulator, inspect the flame scanner lens, and verify the ignition spark is audible and consistent.
When to call us
If the burner locks out repeatedly after reset, stop trying — every failed ignition cycle stresses the fan and fuel valve. Call for a burner service with combustion analysis.
Likely causes
What to check
Log the pressure at which the valve lifts and compare it to the rated set pressure. Inspect for visible steam at the discharge pipe.
When to call us
A lifting or weeping safety valve must be serviced or replaced immediately — it's a legal requirement under the Pressure Equipment Regulations. Never cap or plug it.
Likely causes
What to check
Check deaerator level, pump suction and discharge pressures, and listen for cavitation noise. Inspect the suction strainer.
When to call us
If the pump can't maintain feedwater flow to match steam demand, the boiler will trip on low water. Call for pump service before the boiler cycles off and production stops.
FAQ
The Pressure Equipment Regulations require an annual inspection by an Approved Inspection Authority. We schedule this with a full tube inspection, safety valve calibration and combustion tune-up. High-utilisation industrial plant may need quarterly burner checks.
Annual inspection and service typically ranges from R8 000 to R25 000 depending on boiler size, fuel type and tube count. Repairs and tube replacement are quoted separately after inspection. Send us the nameplate and we'll give you a fixed quote within 24 hours.
Yes. We arrange the annual inspection with a registered AIA, prepare the boiler, carry out any repairs flagged, and issue the CF. We keep the records on file for your next audit.
Yes — we service and tune all major burner makes on gas, LPG, HFO, diesel and dual-fuel configurations, including combustion analysis and emissions logging.
Same-day in Gauteng for production-critical plant. We carry common burner spares, safety valves and controls, and can arrange temporary steam if a major repair is needed.
Yes — ultrasonic and temperature survey of your full trap population, with a report identifying failed open (wasting steam) and failed closed (waterlogging) traps. Most plants recover the survey cost in fuel savings within weeks.
