Equipment solutions for FPS MULTIPLE FUEL FIRED BOILERS FOR STEAM OR HOT-WATER Aalborg OM Aalborg OL Aalborg D BURNERS & CONTROLS GOSFERN™ 8.0 – 45.0 t/h 12.0 – 55.0 t/h 5 – 45 MW The boiler is available as a steam boiler in capacities up to 45 t/h or as a hotwater boiler in capacities up to 30 MW at 11 or 18 bar design pressure. The boiler consists of a furnace and a convection part integrated with the steam drum. The flue gas flows vertically from the furnace up through the pin element tubes in the drum to the flue gas box at the top of the boiler. The boiler is side-fired, which makes the boiler very easy to ventilate and gives an operation and maintenance friendly location of the burner and its controls. The boiler is available as a steam boiler in capacities up to 55 t/h, or as hotwater boiler in capacities up to 35 MW with a design pressure of up to 18 bar. 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. The ideal choice when large steam capacities are required. The standard capacity range is 45–120 t/h saturated steam at 18–25 bar. As a hot-water boiler, it can be delivered with a capacity of up to 80 MW. For FPS applications, the boiler can also be delivered for capacities up 130 t/h at 40 bar and 400ºC superheated steam. The GOSFERN™ MPF (Marine Para-Flow) burner comes in roof/wall fired designs, capable of burning MDO, HFO, crude oil or fuel gas in single, dual or triple fuel combinations. Another burner is the MPF-LE (low emission) burner for environmentally sensitive applications. The Aalborg D boiler consists of a steam and water drum connected by a generating tube bank. The furnace is made of membrane walls forming a fully water cooled furnace. The convection section consists of straight pin tubes with bent pins that provide a high heat transfer coefficient and a low pressure loss. Large external downcomers secure good natural circulation at all loads. The burner assembly is provided as a complete module, incorporating dual redundant flame scanners, internal gas ring, oil gun and igniter with all electrical components precabled to the front-plate mounted SS junction box. In addition, all instrument air users are pre-tubed (SS) to a common manifold, also mounted on the burner. 4
