The most outstanding feature of the V2M9 marine boiler is the combustion. The boiler is a vertical two-drum dropped-furnace boiler. A burners are located at each of the four corners of the furnace and the burners are aligned to be tangential to a circle in the center of the furnace. This arrangement gives a rotary motion to the combustion gases within the furnace, with improved turbulence and air/fuel mixing. This lengthens the fuel-particle residence time in the boiler and allows combustion to be completed before the gases pass into the convection generating bank and superheaters.

Blue: the downcomers lead the water from the steam drum to the water drum and the water walls headers.
Red and blue: the evaporation tubes and the waterwalls lead the water and steam emulsion back to the steam drum.
Red: the steam passes through the superheater before it leaves the boiler for the consumers.
