Successful startup at ICT of ANDRITZ Novimpianti tissue machine heat recovery

Austria-headed international technology group Andritz AG (ANDRITZ) has announced the successful startup of a heat recovery chain of the tissue machine PM3 at ICT in Piano di Coreglia, Italy. The heat recovery chain, supplied by ANDRITZ Novimpianti, includes a PrimeDry Yankee Ecosteam System (YES) that produces approximately one-third of the steam required for the Yankee by utilizing exhaust air from the Yankee hood. Thus, energy costs and carbon dioxide (CO2) emissions can be reduced.

With a capacity of about 620 000 tonnes per annum, ICT is one of Europe’s leading tissue producers. ICT and ANDRITZ partnered for the first time in 2001 when ANDRITZ successfully installed the tissue production line PM11 at ICT Poland in Kostrzyn, followed by several conjoint projects in Europe.

The PrimeDry YES Yankee Ecosteam System produces approximately one-third of the steam required for the Yankee by utilizing exhaust air from the Yankee hood. Additional energy savings are reached with the new PrimeDry Heat Recovery system that recovers and reuses the heat generated during the tissue drying process and the air-to-air process heat exchange for make-up and combustion air.

The upgrade of the complete heating and room ventilation system of the plant was part of the scope as well.

ANDRITZ Novimpianti – part of ANDRITZ since 2018 –  has more than 30 years of experience designing, installing, and servicing drying technology for all kinds of tissue and paper machines around the world.

The heat recovery chain for tissue machine PM3 at ICT in Piano di Coreglia, also means that more than 30 PrimeDry YES systems are in operation – which ANDRITZ says is a “benchmark” in the tissue industry.
