Shredders installed at one of Finland’s largest waste-to-energy plant
UNTHA has installed a robust 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.
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 123.300.000 EUR project for local utility company Riikinvomia Oy.
Capable of processing 145,000 tonnes of waste a year – collected from a region inhabited by 640,000 citizens – the new CFB (Circulated Fluidized Bed) plant will produce 16MW of electricity as well as 38MW for district heating, per annum.
The electric-drive pre shredders will achieve throughputs of 41 tonnes per hour, before the post shredders produce 16.5 tonnes of homogenous <80mm output fuel per hour.
Commenting on the project, UNTHA’s sales manager Andreas Neureiter said: “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.
“Our shredders were chosen due to their proven robustness, low noise and ease of maintenance. UNTHA’s ultra-efficient Eco Drive concept was also key, given the finished plant will have outstanding environmental credentials.”
With the pre and post shredders part of the same UNTHA series, all machines will utilise the same spare parts – another value-adding benefit. The technology is also single-drive as opposed to the more power consuming, dual-drive concepts proposed by competitors for this facility.
Andy 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.
