Cleaning Services for Aalborg boilers

Your Alfa Laval Aalborg boiler accounts for much of your vessel’s fuel consumption, so even a minor decrease in its heat transfer efficiency has an impact on operating costs. By washing the boiler regularly to remove accumulated soot, you can keep its efficiency at a maximum.

We provide the Alfa Laval Aalborg boiler water washing kit for removing soot from pin tubes and other heat transfer surfaces in your boiler’s convection section. Although Aalborg boilers have a high gas velocity that minimizes fouling under normal combustion conditions, a certain amount of soot build-up will inevitably occur over time. The washing procedure combines soaking with clean water and the use of compressed air to create turbulence. This is an efficient and affordable cleaning method with excellent results.

The water washing kit makes cleaning the boiler easy, as demonstrated on the container ship Maersk Dubrovnik. Tests performed on the vessel’s 4000 kg/h oil-fired Aalborg boiler have shown the crew can perform cleaning in as little as 7-8 hours. This small time investment can result in measurable savings. Marine industry statistics show that a soot build-up of just 0.8 mmm corresponds to a 2% fuel loss.
