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.

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.

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.
