Billerud, one Europe’s largest producers of packaging paper, has awarded Siemens Power Generation (PG) 20 million Euros to supply three steam turbine-generator sets to mills in Karlsborg, Gruvön and Skärblacka.
The SST-600 backpressure turbine-generators will supply the Swedish mills with electricity and process steam for the production of pulp and packing paper.
The turbine-generators rated at 46 MW (Karlsborg), 49 MW (Gruvön) and 50 MW (Skärblacka) are scheduled for delivery between April and September 2006. As a result, the facility will be able to produce approximately 60 percent of its electricity needs, up from the current 30 percent production.
In addition, the boilers will be converted from straight oil firing to supplementary firing with biomass, which will translate into annual oil savings of approximately 30 million litres. PG says CO2 emissions also will drop significantly. Because the project makes an important contribution towards fulfilment of the Kyoto requirements, the Swedish government is supporting it by issuing green certificates.
The Siemens PG scope of supply and services encompasses the three direct-drive backpressure turbines, which will be produced at the company’s manufacturing plant in Görlitz, Germany, and the associated generators from its plant in Erfurt, Germany. The order also includes complete installation and commissioning of the turbine-generator sets.
