What payback can we expect from waste heat recovery?

It depends on exhaust temperature, run hours and the steam value it displaces. On continuously running gas engines, a well-designed recovery boiler often pays back within 2–4 years. We quantify this from your actual load logs.

Can you add a waste heat boiler to existing generators?

Frequently yes, provided the exhaust temperature and back pressure allowance suit it. We survey the exhaust route and prime mover limits before design.

How often do heat recovery boilers need cleaning?

Clean-burning gas engines may go 12 months; diesel, biomass and furnace off-gas applications often need quarterly cleaning driven by measured performance rather than the calendar.

Troubleshooting

Common waste heat boiler faults in Vanderbijlpark

Falling steam output at the same engine load+
Likely causes
- Exhaust-side fouling on the tube bundle
- Waterside scale reducing heat transfer
- Bypass damper leaking past
What to check
Compare exhaust inlet and outlet temperatures with commissioning data — a narrowing gap means poor transfer.
When to call us
When cleaning intervals stretch beyond schedule or output drops more than 10%.
Excessive back pressure on the prime mover+
Likely causes
- Severe soot or ash blockage
- Damper mechanism failure
- Undersized or partly blocked ducting
What to check
Measure back pressure at the engine or turbine outlet against the manufacturer limit.
When to call us
Immediately — excess back pressure damages the engine or turbine and can void warranty.
Tube leaks and water carryover+
Likely causes
- Thermal fatigue at tube-to-tubesheet joints
- Acid dew point corrosion at low load
- Poor feedwater treatment
What to check
Watch for unexplained make-up water use and steam quality problems downstream.
When to call us
At the first sign of leakage — a failed tube can flood the exhaust path.
