ERLANGEN, Germany, Aug. 1, 2016 (Press Release) -Two Siemens SST-800 steam turbines are supplying electricity and process steam to a pulp factory in Brazil. The SST-800 has a capacity of 190 megawatts (MW), making it among the largest steam turbines in use in the pulp and paper industry worldwide. The plant has a total capacity of 270 MW. The customer is Klabin, a leading manufacturer and exporter of paper and packaging.
An extraction backpressure steam turbine and a condensing steam turbine supply electricity and process steam for the pulp factory in Ortigueira, in the southern Brazilian state of Paraná. "For the Klabin project we delivered highly specific, very complex steam turbines that the customer has integrated into a customized process cycle. These two Siemens SST-800 steam turbines are a very good example of our excellent performance capabilities in terms of complex, customer-specific steam turbine projects," said Ronald Schmidt, head of Europe Industrial Steam Turbines at the Siemens Power and Gas Division.
The new plant is uniquely flexible, because it has two production lines and can produce two types of fiber simultaneously. The factory has an annual production capacity of 1.5 million metric tons of pulp. 1.1 million metric tons of bleached hardwood pulp (eucalyptus) and 400,000 metric tons of bleached softwood pulp (pine), a portion of which is converted into fluff pulp for products like baby diapers.
Approximately 150 MW of electricity, or more than half of the total of 270 MW produced, is fed into the national power grid. That's enough to supply electricity to a city of a half-million people.
