Benefits of natural circulation

• Lower capital expenditure (CAPEX)

• Lower operational expenditure (OPEX)

• Maximized uptime and operational safety

• Lower parasitic electricity consumption for steam generation

• Easy boiler water chemistry control. Tolerant to varying

make-up water quality and no need for condensate

polishing

• Lower weight and less crowded layout due to simpler

circulation line piping when compared to conventional

forced-circulation systems

Extended scope

Alfa Laval’s supply comprises a high number of in-house

products beyond the HRSGs themselves, such as plate heat

ex-changers, steam drums, feed-water deaerator tanks,

condensate tanks, blow-down tanks and solutions for boiler water

chemistry management. The remaining equipment, such as

pumps, instrumentation and valves, are sourced from reputable

makers who are suitable for the offshore environment and your

specification levels. The wide internal scope, combined with Alfa

Laval steam system expertise, ensures professional customer

support – all the way from concept development to ser-vice

requirements over the solution lifetime.
