Design data

Description

MISSION™ OL is a high performance, large capacity oil-fired marine boiler with a steam capacity range from 12.5 to 55 t/h. MISSION™ OL is a vertical top-fired two-drum boiler constructed from standard modules.

The boiler is delivered as a preassembled unit with an integrated steam atomising burner and control system.

Construction

The MISSION™ OL design features straight tubes directly connecting the water and steam drums. This
ensures safe circulation with no risk of overheating and subsequent burnout of the tubes.

Thanks to gastight, polygonal membrane wall panels the sturdily constructed furnace is resistant to gas
pulsations. The integrated burner design reduces refractory to a protective layer at the bottom of the furnace and around the access doors.
