What do we mean by 'firetube' when we talk about industrial steam boilers?

When an industrial steam boiler is fire-tube, it means that the hot gases produced during combustion circulate inside tubes that run through the boiler, while the water to be heated surrounds the outside of these tubes. This configuration provides efficient heat transfer and a robust design that makes it ideal for industrial applications requiring high-quality saturated steam and dependable performance.

At ATTSU, we offer a wide range of fire-tube boilers tailored to different fuels and power requirements, including:

• HH model: a horizontal fire-tube boiler for liquid and gaseous fuels, designed to deliver high efficiency, low consumption, and easy maintenance.
• RL model: a three-pass fire-tube boiler, perfect for demanding industrial environments that require maximum reliability.
• RL-BajoNOx model: a version specifically engineered to reduce pollutant emissions without compromising energy performance.
• CS model: a biomass fire-tube boiler, ideal for companies looking for a sustainable option using renewable solid fuels and making the most of the energy available.

All our fire-tube boilers comply with the most stringent international safety and efficiency standards. In addition, their modular construction and easy access for inspections and maintenance ensure a long service life and highly competitive operating costs.
