Steam Boilers MISSION OC

Vertical smoke/water tube type Standard preassembled boiler unit Integrated pin tube elements Integrated control panel Quick and easy installation Designed for operation with a monobloc-type pressure jet or rotary cup burner Design data Thermal output: up to 3.5 MW Steam capacity: 0.75 - 5.0 t/h from the oil-fired section Up to 3 t/h from the exhaust gas section Design pressure: 9 bar(g) 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 smoketubes 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 tubeby a factor of 8. ConstructionMISSION" 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. BurnerMISSION" 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. DATA SHEET series? Aalborg Industries 2002, rev.: 2.0 October 2005 (Design data are subject to change without prior notice).
