Nov 02, 2009. /Lesprom Network/. Metso will upgrade the recovery boiler automation system at Stora Enso Imatra Mills in Finland. The start-up is scheduled for September 2010, Metso Automation said in a press release received by Lesprom Network. The existing Damatic XD automation system at Imatra mills, supplied by Metso’s predecessor Valmet Automation in the 1990s, will be replaced with a metsoDNA CR distributed control system. At the same time, the boiler safety system will be upgraded to meet today’s requirements. The delivery also includes installation and user training. Through the investment Stora Enso will be able to extend the life cycle of the recovery boiler automation by 15-20 years and enhance the overall operation of the chemical recovery line.
