Aalborg OC Modular composite boiler Aalborg OC is a high performance, combined oil and exhaust gas-fired boiler, with a 750-5,000 kg/h capacity of the oil-fired section at 9 bar(g) design pressure. Aalborg 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 optimised to achieve lower weight and improved strength. The result: longer lifetime of the pin tube by a factor of 8. Description Aalborg OC is a high quality composite boiler design offering the space-saving alternative of two boilers combined into one. Aalborg OC is a combined oil and exhaust gas-fired boiler with a capacity range of up to 5,000 kg/h steam from the oil-fired section and up to 3,000 kg/h from the exhaust gas section. It is a standardised, preassembled boiler plant that is fast and easy to install even if we design the boiler from case to case to get optimum design. Aalborg OC is designed according toAlfa Laval's modular Aalborg boiler concept. Aalborg OC engages less deck area and has lower weight than older designs of composite boilers. Construction Aalborg 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 minimised by the simple design of cylindrical shells with flat plates of equal thickness. Burner Aalborg OC is equipped with a Aalborg type pressure-jet burner or Aalborg types rotary cup burner. The burner is 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 utilisation of the furnace and the result is a high performance combustion - even with.

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, Aalborg OC can be equipped with a rotary cup burner. Control system The reliable and userfriendly microprocessor based Aalborg control system facilitates the operation and control of the Aalborg OC boiler. The control system provides fully automatic operation of the boiler plant and the pressure jet burner. The Aalborg control system includes burner load and sequence controls, water level and safety device, burner motor and fuel...
