Description
MISSION™ OC is a high performance,
combined oil and exhaust
gas-fired boiler, with a 0.75-5 t/h
capacity of the oil-fired section
at 9 bar(g) design pressure.
MISSION™ OC is a vertical, cylindrical
boiler with an exhaust gas
section consisting of bare smoke
tubes while the oil-fired section
features pin tubes in the convection
section.
Pin tube element
The boiler design has integrated pin
tube elements. The pin tube elements
support both the furnace and the
boiler top plate. The design has been
significantly optimized to achieve lower
weight and improved strength. The
result: longer lifetime of the pin tube
by a factor of 8.
Construction
MISSION™ OC is a vertical boiler with
an exhaust gas section consisting of
bare smoke tubes. The cylindrical shell
surrounds the smoke tubes, the furnace,
the steam space and the convective
section, which consists of pin tube
elements. The boiler pressure part is
manufactured from mild steel able to withstand high temperatures. Stress
concentrations in corners are minimized
by the simple design of cylindrical shells
with flat plates of equal thickness.
Burner
MISSION™ OC is equipped with a
monobloc type pressure-jet burner.
The burner is hinge-mounted and can
be swung out for service and easy access
to inspect the furnace. The burner housing is mounted on the boiler front,
angled 15 degrees downwards against
the furnace bottom. This allows for a
long flame and offers better utilization
of the furnace.
The flow of the combusting particles
becomes optimal, and the result is a
high performance combustion - even
with the lowest grades of fuel.
As an alternative, MISSION™ OC can
be equipped with a rotary cup burner.
