Celulosa Arauco y Constitución S.A., Chile, has signed an agreement for Metso (future Valmet), Finland, to upgrade and repair a power boiler at its Constitución mill in Chile. The order will be supplied by Metso’s units in Finland and Brazil. The project will be completed by the end of 2014. The value of the order was not disclosed.

This project includes a major repair and upgrade of the existing power boiler. The intent of the project is not only to bring the boiler back into reliable and serviceable condition, but also to improve its operation. The delivery will include the following main parts: replacement of the secondary superheater, conversion of the boiler to a modern single-drum design, replacement of tubular flue gas air heater, new biomass feeding system, new and improved combustion air supply system, and new heavy fuel oil fired load burners.

"The upgrade and repair of the boiler will significantly extend the boiler’s lifetime and secure its safe operation. This project will also improve the availability and controllability of the boiler, and reduce operational costs as well," Jouni Koskinen, sales manager, Pulp, Paper and Power, Metso, explained.

"We have been working together with Metso for many years and, in general, we think the cooperation has been successful for both parties," said Patricio Henriquez, director of Arauco’s Engineering and Construction Division. "Other determining factors for choosing Metso as a supplier were technical solutions and know-how, project execution competence, and delivery time."

Jouko Kylänpää, director of services, Pulp, Paper and Power, Metso, added that "this co-operation project with Metso’s Finnish and Brazilian teams is in line with our strategic target to continue further globalization of our capabilities to be closer to customers and to excel in serving our customers."
