International technology group Andritz has successfully started up state-of-the-art and environmentally leading pulp production and chemical recovery technologies for Klabin's Puma II line in Ortigueira, Paraná, Brazil.
The Andritz scope of supply included:
- A wood processing plant with debarking and chipping line, which can process both eucalyptus (350 m3 sob/h) and pine (400 m3 sob/h), meaning that a log truckload of wood is emptied onto the line every ten minutes.
- The HERBTM recovery boiler from Andritz, which has a capacity of 3,300 tds/d with high steam parameters of 103 bar(a) and 502°C to maximize power generation. It is equipped with the autonomous Smart sootblowing control solution that combines Smart sensors (HEWI) and controls to ensure the cleanability period, a higher availability of the boiler, as well as greater operating safety.
- A power boiler based on Andritz EcoFluid bubbling fluidized bed (BFB) technology with a steam production capacity of 220 t/h. It is combined with the recovery boiler to form a "boiler island", and some of the auxiliary equipment is shared between the two boilers. This provides savings in investment and operating costs.
-A complete white liquor plant consisting of a recausticizing plant (5,000 m3/d) and an Andritz LimeKiln (450 t/d) with a multi-fuel burner.
Andritz Pulp & Paper provides equipment, systems, complete plants and services for the production of all types of pulp, paper, board and tissue.
