Description


MISSION™ D is a high performance oil-fired marine boiler with a steam capacity range up to 120 t/h. MISSION™ D is of the well proven top-fired two-drum D design. The boiler is built for lifelong reliability and low maintenance costs.

 

The boiler is especially suited for tanker installations producing steam for cargo pump turbines, heating, tank cleaning as well as producing inert gas.

 

 

Design


The MISSION™ D boiler is of the well proven two-drum D-type design and is made in standard sizes up to 120 t/h of steam.


The MISSION™ D boiler consists of a steam and water drum connected by a generating tube bank. The furnace is made of membrane walls forming a fully water-cooled gas-tight furnace.
Large unheated external downcomers welded to the drums secure natural water circulation – with a large circulation ratio.
