PAPERTECHNOLOGYINTERNATIONAL Toscotec launches breakthrough innovations for a more sustainable tissue making - Paper Technology International 2023
A disruptive innovation for dry crepe and TAD tissue machines
With TT Induction SYD, the internal steam distribution and
steam/condensate removal systems are entirely replaced by an
induction system composed of static coils installed inside the shell
and electrical controls and instrumentation located outside for easy
maintenance and monitoring. As a result of precise coil geometry,
the induction system delivers a very fast and accurate heating
effect exactly on the areas of the shell where it is required, while
preventing residual circulating currents in other areas.
Steam-heated Yankees use steam energy typically
generated by burning fossil fuels. TT Induction SYD uses electrical
energy that can be derived from renewable energy sources while
delivering the same result, i.e. uniformly heating up the Yankee’s
shell in contact with the paper web to achieve dryness. TT Induction
SYD is suitable for installation on dry crepe as well as Through-AirDrying (TAD) tissue lines.
Luca Ghelli, Toscotec R&D Director, says, “Sustainability
is the guiding idea of TT Induction SYD’s design. As a proven
industrial technology, an induction system offers multiple advantages
when applied to the most energy-intensive section of the tissue
machine. The efficiency of this cutting-edge technology will
dramatically reduce the carbon footprint of papermaking. Based
on our expertise in steam-heated TT SYD and induction systems,
we succeeded in developing a more efficient and sustainable steel
Yankee dryer.”
Substantial carbon reduction with unchanged productivity and
paper quality
Normally, approximately half of the carbon dioxide emissions
produced by a tissue machine originate from the operation of the
Yankee dryer. By using clean energy, TT Induction SYD achieves
zero direct emissions, while maintaining productivity unchanged
and reducing energy consumptions because of the higher efficiency
of the induction system. Due to the precise heating of the shell, it

also eliminates possible moisture profile issues related to uneven
condensate removal, thereby ensuring an improvement in moisture
uniformity in both cross direction (CD) and machine direction (MD).
Maximum safety, easier operation, and maintenance
TT Induction SYD was designed without any electrical,
mechanical, and radiation risk to ensure maximum safety. Besides
offering safe operations, it also clears all issues related to the
maintenance of steam-heated Yankees, including pressure vessel’s
mandatory and planned controls, maintenance of condensate straw
pipes against potential plugging and of special heads for steam and
condensate inlet and outlet. The entire Yankee system is simplified
in the absence of steam: the heads, the internal surface which
is groove-less, and the steam and condensate auxiliary system
disappears entirely, including the steam generator with related
maintenance and controls and delicate controls for steam quality. TT
Induction SYD simply requires relatively easy maintenance on the
electromagnetic induction system.
3. TT Hydrogen Burner
TT Hydrogen Burner is a new generation of 100% hydrogen
fueled burners especially designed and tested by Toscotec for
Yankee hoods. Within the context of the energy transition from
fossil-based to zero-carbon industrial operations, Toscotec
developed this patented innovation to drive the conversion of paper
manufacturing to clean energy.
TT Hydrogen Burner is an in-line burner featuring precisely
controlled combustion and two safe operation modes. In carbonfree mode it runs on 100% hydrogen; in carbon-reduction mode
it is fueled by a mixture of natural gas and hydrogen, where the
percentage of hydrogen is accepted across a wide range.
