Oil and gas-fired industrial boiler
Enhance steam production efficiency with a robust three-pass combustion system designed for optimal heat transfer and reduced flue gas emissions, ideal for demanding operational environments.

Generates Steam and Transfers Heat Efficiently
The Aalborg 3-Pass from Alfa Laval is an industrial oil and gas-fired boiler engineered to excel in steam production and heat transfer operations. Utilizing a three-pass design, it ensures symmetrical heat distribution and optimal water circulation, enhancing combustion efficiency and minimizing flue gas emissions. This boiler is versatile, serving industries such as oil and gas, power generation, and chemical manufacturing, and is crucial for producing refined petroleum and industrial steam.
With a heat capacity ranging from 1.5 to 25.5 MW and steam capacity of 2.0 to 39 t/h, it operates under pressures up to 20.7 bar g, delivering saturated steam. The Aalborg 3-Pass integrates seamlessly into continuous, fully automatic operations, featuring a built-in burner management system and the option for POMC load-sharing technology, which optimizes load distribution among multiple boilers.
The unit’s compact design facilitates easy installation and integration, while all connections and valves are top-mounted for straightforward inspection and maintenance. Equipped with manholes, it supports internal cleaning and maintenance efficiently. Additionally, it offers configuration flexibility with optional economizers, superheaters, and condensate tanks to enhance performance and meet specific production needs.
