Alfa Laval Aalborg 3-Pass - Oil and Gas-Fired Industrial Boiler

The heating surfaces are arranged symmetrically with the furnace in the centreline of the boiler to secure optimum water circulation. The furnace is designed with a plain surface for low pressures and with a corrugated furnace for higher pressures and capacities. The reversal chamber is fully water cooled to reduce the refractory to a minimum.

The pressure part builds on well documented design and production concepts. All pressure parts are manufactured in carefully selected materials without high tensile steel.  

• Burner Management System with load and sequence control
• Water level control and safety equipment
• Motor and oil heater starters

The control system can be enhanced by a load-sharing system which regulates the load between several boilers in one system, based on the POMC technology (Process-Optimising Multivariable Control). The POMC load-sharing system considerably boosts the boilers’ total efficiency over earlier generations of load-sharing systems.

Aalborg 3-Pass comes with a burner of either the pressure atomising, steam atomising or rotary cup type for fully automatic operation. Burners for fuels such as natural gas, oil or combined firing of gas and oil can be offered.
