Simulation is gaining importance for the pulp and paper industry, as the simulators have become increasingly realistic and provide challenging training for the operators.
New recovery boiler for generating green electricity
In 2006, SCA Östrand pulp mill invested in a simulator for its new recovery boiler. The new recovery boiler from Andritz was put into service on the 9th of October 2006 and cost 1.6 billion SEK (approx. 145 million €). It generates 500 GWh green electricity annually.
Good experiences from previous endeavours are among the reasons that the use of simulators is on the increase in the pulp and paper industry. Thus, a simulator became part of the ABB system that controls the boiler . Andritz also delivered the process model.
"The whole package must be in accordance with our needs", states Lars-Åke Sundberg, system engineer at SCA Östrand. "Among the final suppliers we were choosing from, ABB’s solution for the simulator was the best option. It gave us a very realistic simulation, as the functionality in the simulator is the same as in the real automation system, with additional simulation functions. Other alternatives, such as emulating the automation system by the model vendor, seemed far less suitable for us."
