ANDRITZ successfully starts up tissue machine with the world’s largest steel Yankee dryer in Brazil
International technology Group ANDRITZ has successfully started up the PrimeLineST W22 tissue machine with steel Yankee dryer and steam-heated hood delivered to Carta Fabril, for its mill in Anápolis, Brazil.
Due to the outstanding and short commissioning period, paper production on the new tissue machine started well ahead of schedule.
The PrimeDry Steel Yankee delivered by ANDRITZ has a diameter of 22 ft. and thus is the largest in the world for tissue applications. The combination with the steam-heated hood enables highly efficient drying with substantial energy savings compared with conventional drying sections with cast Yankee dryers and gas-heated-hoods. The steam-heated hood is equipped with an innovative, automatic cleaning system to ensure easy maintenance and safe operations.
The ANDRITZ PrimeLineST W22 has a design speed of 2,100 m/min and a width of 5.55 m. It will produce tissue with grammage of 15 g/m2 that is used for two-ply toilet paper.The scope of supply also included the complete stock preparation plant and approach flow system, which processes 100% short fiber (eucalyptus) as raw material. The centerpiece of the line is the ANDRITZ Papillon refiner, which treats fibers gently in the cylindrical refining zone in order to achieve superior fiber properties at low energy consumption.
“The early start-up was only possible because of our cooperation with ANDRITZ. We are now proud to have the world’s largest steel Yankee, which is predicted to enable efficient drying with substantial energy savings. Our target is “green production” by minimizing energy consumption, liquid and solid waste, effluents, and CO2 emissions. The new tissue machine will use 100% renewable energy generated from biomass and converted into steam. The project presents a very good example of environmental, economic, and social sustainability,” says Victor Coutinho, CEO, Carta Fabril.
The successful start-up of the world’s first tissue machine with a 22 ft. steel Yankee confirms ANDRITZ’s strong position as one of the global market leaders for supply of complete tissue production lines, key components, and services.
Carta Fabril ranks among the key players in the Brazilian tissue business, covering the complete product range for tissue.
