Wärtsilä Waste Treatment

A complete waste management solution for Cruise Ships

Unique incinerator for a cleaner and healthier environment

Operating in today’s cruise market can be a challenge with all the new environmental regulations applying to cruise ships. It is a requirement that the effluent from a ship must be clean and safe. Wärtsilä’s Hamworthy has a proven track-record in developing technology to meet these anticipated environmental standards. Our solutions have set the global benchmark for wastewater management. Wärtsilä can provide a complete, fully integrated package for wet and dry waste treatment.

Unique features

The Wärtsilä incinerator combines innovative technology with benefits of using paddle technology and the wet-de ashing system. The (Water Cooled Paddle System) requires only a short combustion chamber, due to the forward and backward movement, resulting in an optimal mixing of waste during the incinerating process. Since the combustion process takes place on the bottom of the incinerator, the air supply is above the burning waste, which results in reduced airborne ash. The paddle system has water cooled shafts and paddles made from Inconel, which cannot be overheated.

The wet de-ashing system eliminates airborne ash in the dry waste compartments, resulting in a cleaner and healthier working environment for personnel. In addition, it is easy to handle ash bags and reduces maintenance on other equipment installed nearby.

    Wärtsilä incinerator vs. conventional

    System technology Wärtsilä incinerator Effect Conventional Effect
    Airborne ash reduction Unique wet de-ashing system with air supply from above eliminates airborne ash Cleaner and healthier working environment for personnel Moving grate with an air supply from below results in a high amount of airborne ash Working environment with unhealthy ash to breathe
    Ash handling Easy handling of ash bags Less work for personnel Challenging handling of dry ash More unhealthy work for personnel
    Side effects of airborne ash Eliminated airborne ash reduces maintenance need on other equipment installed nearby Savings in the form of reduced maintenance need High amount of airborne ash requires costly maintenance on nearby equipment Increased costs for equipment maintenance
    Operational reliability The forward and backward movement of the paddle technology results in an optimal mixing of waste The optimal mixing of waste during incineration and water-cooled shafts and paddles made from Inconel ensures system cannot get overheated A moving grate can transport the waste only in one direction, which is not the most efficient process Will become blocked with solid particles after a very short time resulting in overheating and stoppage
    Space requirement on board for same burning capacity The forward and backward movement of the paddle technology requires only a short combustion chamber for the necessary retention time The compact and short combustion chamber saves valuable space on board A moving grate can transport the waste only in one direction, thus requiring a longer design for the necessary retention time The long combustion chamber results in a much larger footprint taking up much valuable space that could be used for something else

    Want to clean the effluents of your ship?

    If you are in the cruise segment, working as an owner/operator or perhaps running a cruise yard, then there is a clear advantage in maintaining a more proactive public image. This can be achieved with a complete waste treatment package optimised for the cruise market.

    Wärtsilä as a global group can contribute with worldwide support 24/7 as well as provide main engines, propulsion equipment and much more. The complete waste treatment package that your cruise ship needs is now available from Wärtsilä. Having only one supplier for the whole package reduces your technical and commercial risks. In addition, the compact size can increase the vessels revenue in terms of more cabin space.
