Innovation and sustainability: Garioni Naval, heat recovery boilers in the paper industry

от | Апр 8, 2024

Svecom-P.E. has been building customized solutions for the winding and unwinding of reel material since 1954. Thanks to the know-how acquired in metalworking, in September 2015 Svecom-P.E. acquires Garioni Naval brand, a historic brand that creates industrial and naval heating systems. Consequently, the manufacturing area, part of the commercial network and customer service are transferred to the Svecom-P.E. headquarters in Montecchio Maggiore (Vicenza).

Genesis of the project and preliminary study

Today, Svecom-P.E. makes the know-how acquired over the years in the paper and tissue sector available also for the production of Garioni Naval heating systems.
The paper industry is constantly evolving, driven by the search for more efficient and sustainable solutions.
It is in this context that the project emerges for an important company in the paper sector based in Lucca (Italy): a recovery steam generator with water tubes, in compact, modular design with finned tubes. The project came to life in December 2022, when the first study was launched to develop a system capable of recovering and exploiting the heat coming from exhaust fumes. This ambitious goal was translated, after a careful analysis, into a solid and innovative commercial proposal.

Sustainability and environmental impact

A fundamental aspect of the project is its contribution to the sustainable ecosystem:

  • By using this type of solution, CO2 emissions are drastically reduced: the heat recovery boiler is in fact designed to recover waste heat without the use of non-renewable fossil fuels.
  • A large part of the water is collected from the condensed steam and is pumped at high temperature to conserve as much heat as possible, minimizing losses to the atmosphere.
  • The project is in line with the goals of reducing environmental impact. Considering that the plant is active 24 hours a day, we are talking about approximately 12,000 tonnes of CO2 saved every year. A fossil fuel boiler of the same power would emit around 1500 kg of CO2 into the atmosphere per every hour of operation and would consume around 6 million Nm3/h of gas per year.

Technological innovation

Steam generators are traditional products historically available in many different forms: an uncommon peculiarity of this creation is its modularity, which facilitates transport on site and any future expansions. The product is highly customizable, reflecting the increasing demand for tailor-made solutions in the paper industry. In recent years, between the end of 2022 and the first half of 2023, 4-5 similar projects have been advanced, each characterized by unique design specifications. One of the most notable aspects of the project is the completion time: just four months, including ASME certification. This speed of execution represents a successfully overcome challenge, considering that similar projects generally require more time. The extraordinary performance was achieved thanks to an efficient organization and the adoption of advanced methodologies.
