Description
The boiler is available as a steam or hot-water
boiler in capacities up to 55 t/h or 42 MW.
The convection section consists of
straight tubes extended with pins
which are bent to create a flue gas
flow increasing the heat transfer at
the same time as it reduces the pressure
loss across the convection section.
The boiler is top-fired, which gives
optimum conditions for the flame
resulting in a very good combustion.
The boiler is compact and requires a
minimum of space.
It is ideal for engine room installation.
Construction
The MISSION™ OL is a large capacity oil-fired steam or hot-water boiler in the 12.5 to 55 t/h capacity range. The two-drum cylindrical boiler 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. |
