Valmet will deliver a recovery boiler upgrade to Lecta Group's Torraspapel combined pulp and paper mill in Zaragoza, Spain. The upgrade will increase the capacity of the pulp mill's recovery boiler and reduce the mill's emissions. The value of the order will not be disclosed.

The primary target of the upgrade is to increase the recovery boiler's black liquor capacity. The upgrade will also reduce the mill's emission levels and improve the water side of the boiler, hence enabling the capacity increase. The upgrade will take place during the mill's annual shutdown in October 2023.

"The project will help Lecta to optimize the energy balance of Zaragoza mill as well as make progress in our medium-term decarbonization plan. It also contributes to eliminate a bottleneck for possible future growth in production and/or use of other eucalyptus species. Valmet has always been a reliable and trustworthy supplier for Lecta, with a high degree of technical capabilities in the pulp and paper areas." says Primitivo Prados, Mill Manager at Torraspapel mill.

Valmet's delivery includes a comprehensive recovery boiler upgrade with new secondary and tertiary air systems, new black liquor sprayer stations, modifications in the water side of the boiler and new smelt spouts. The upgrade will increase the recovery boiler's capacity from today's 420 tds/d including ashes to 480 tds/d including ashes and reduce the mill's emissions.
