Valmet to Supply Fine Paper Machine and Recovery Boiler for Sun Paper Beihai Mill in China
The new 11,150-mm-wide fine paper machine is designed to produce 500,000 tonnes per year of high-quality woodfree uncoated paper grades in the basis weight range of 50-100 g/m2.
April 27, 2020 - Valmet will supply a fine paper making line with stock preparation, an extensive scope of automation and a recovery boiler for Sun Paper in Beihai, China. In addition, another stock preparation line for a different Sun Paper site will be supplied.
The new 11,150-mm-wide fine paper machine is designed to produce 500,000 tonnes per year of high-quality woodfree uncoated paper (WFU) grades in the basis weight range of 50-100 g/m2. The design speed of the machine is 1,800 m/min.
The recovery boiler is designed for high power generation and environmental performance.
The value of the orders will not be disclosed, but Valmet said the total value of orders of this type and delivery scope is typically around EUR 130-150 million.
Valmet's delivery is part of Sun Paper's new greenfield mill in Beihai, which will eventually have a total pulp and paper capacity of 3.5 million tonnes annually. The mill will be constructed in two phases over approximately five years.
"Our overall target of the project is to build a world-class mill. We wanted to choose advanced and reliable technology that is safe to operate. We chose Valmet based on the good cooperation in our previous projects. Valmet also met our targets well," said Fei Da, Recovery Island Project Manager, Sun Paper.
Valmet's delivery includes a complete fine paper making line (PM 1) from stock preparation to parent roll handling and two winders with related air, chemical and process systems, and start-up packages for spare parts, consumables and paper machine clothing.
The stock preparation delivery for PM 1 includes stock lines for softwood, hardwood and BCTMP (bleached chemi-thermomechanical pulp), broke collection, stock mixing and an approach flow system.
The extensive automation package includes Valmet DNA distributed control system with process, machine and drive controls and conditioning monitoring. Also, wet end analyzers and Valmet IQ quality management system with profilers are included.
Valmet's delivery also includes a new high-power recovery boiler with a capacity of 4,600 tDS/d (tonnes dry solids a day). The recovery boiler has multiple high-power features, including multi-stage preheating of feedwater and heat recovery from flue and vent gases to combustion air. The multilevel air system helps to optimize the combustion to reach low NOx and SO2 levels.
Start-ups of the paper making line and the recovery boiler are scheduled for 2021.
