Chemical Cleaning of Marine Exhaust Gas Boiler – Optimised Performance for Shipboard Power Plants
Why Ship Operators Choose Our Cleaning Solution
In the harsh marine environment, exhaust gas boilers accumulate soot, scale, and corrosive salts that degrade heat‑transfer efficiency and raise fuel consumption. Our chemical cleaning of marine exhaust gas boiler service removes these deposits without dismantling the boiler, minimising vessel downtime and extending equipment life. Engine rooms benefit from restored thermal performance, lower emissions, and compliance with IMO regulations, all while protecting capital‑intensive assets.
How the Cleaning Process Works
Our patented formulation is introduced into the boiler’s water‑side circuit through the existing feed‑water line. The solution circulates under controlled temperature and pressure, chemically reacting with carbonaceous fouling, calcium‑based scaling, and iron oxide layers. Within 4‑6 hours, the deposits are transformed into soluble complexes that are flushed out via the blow‑down system. The process concludes with a thorough water‑flush and a neutralising rinse, leaving the heat‑exchange surfaces clean and ready for operation.
The entire operation is monitored by our on‑site technician using portable sensors to verify pH, conductivity, and temperature, ensuring the cleaning meets pre‑defined performance thresholds before the vessel returns to service.

Frequently Asked Questions
What is the minimum order quantity for a ship‑wide cleaning campaign?
We work with both single‑vessel contracts and fleet‑wide programmes. The MOQ is one boiler, but volume discounts apply for multiple units or repeat engagements.
Can the cleaning formulation be customised for different fuel types?
Yes. Our R&D team adjusts inhibitor levels and pH buffers to optimise performance for heavy fuel oil, marine diesel, or low‑sulphur alternatives.
What lead time should I expect from order to on‑site service?
Typical lead time is 15‑45 days, depending on order size, regulatory paperwork, and berth availability. Expedited slots are available for urgent maintenance windows.
Is there a warranty on the cleaning results?
We provide a 90‑day performance guarantee: if post‑cleaning efficiency does not meet the agreed uplift, a complimentary re‑treatment will be performed.
