Reduce fuel consumption and carbon emissions on vessels via online cleaning of boilers.


Discover how we improve boiler performance and eliminate corrosion in the marine industry.

Therma-Chem MB9

Produced for the shipping industry, MB9 was specifically designed to target marine boilers and the unique difficulties they present. MB9 will remove slagging and fouling throughout the boiler and will reduce the time spent in dock for boiler maintenance.

MB9 is a mildly alkaline solution containing nitrates that is designed specifically to clean marine boilers online. Similar to land based operations, MB9 is injected using Therma-Chem’s proprietary injection equipment which will be installed on the ship. Injected directly into the combustion chamber, MB9 is carried by the flue gas throughout the unit encountering all heat transfer surfaces including the wall tubes, superheaters, reheaters and economisers.

MB9 reacts with exisiting hard deposits on tubes by increasing their melting point and reduces them to soft powdery ash.

This allows units to maintain high thermal efficiencies or recover capacity (if this was limited by fouling). MB9 also neutralises sulphur deposits on the cold end of the flue gas path preventing cold end corrosion and eases man entry during a maintenance or inspection shutdown.

In addition, MB9 will reduce NOx, SOx and Carbon emissions. Using MB9 ultimately results in improved heat transfer, prevention of both high temperature and low temperature corrosion, improved operating efficiency and reduced emissions.
