Untha, Kuchl, Austria, has installed a shredding system at a new facility in Leppävirta, Finland, as one of the country’s biggest waste-to-energy power plant edges another step closer to completion, the company says.
Two XR3000 Ripper pre shredders and two XR3000 Cutter post shredders have been supplied to Andritz, the turnkey solution provider responsible for delivering the state-of-the-art $139,274,748 project for local utility company Riikinvomia Oy.
Capable of processing 145,000 tons of waste a year–collected from a region inhabited by 640,000 citizens–the new CFB (Circulated Fluidized Bed) plant will produce 16 Megawatts of electricity as well as 38 Megawatts for district heating, per annum.
The electric-drive pre shredders will achieve throughputs of 41 tons per hour, before the post shredders produce 16.5 tons of homogenous < 80 mm output fuel per hour, the company says.
Commenting on the project, Untha’s sales manager Andreas Neureiter says, “We began talking to Andritz almost three years ago, which shows the level of care and meticulous planning that has gone in to ensure this project is executed perfectly.”
With the pre and post shredders part of the same Untha series, all machines will utilize the same spare parts. The technology is also single-drive as opposed to the more power consuming, dual-drive concepts proposed by competitors for this facility, the company says.
Andreas concludes, “The Riikinvomia Oy plant is a highly talked about, ‘next generation’ plant, which makes this a very prestigious contract for our team. We look forward to the full start up in the final quarter of 2016.”
Plant manufacturer Andritz has also been contracted to supply the CFRB boiler, wider waste treatment technology, flue gas cleaning systems, a steam turbine, electrification, automation and auxiliary systems.
