Fuel for a 30-MW biomass CHP
The CHP plant provides electricity for approx. 40,000 homes and is ready to feed hot water into a district heat network. To ensure that the power plant operates with maximum safety and efficiency, the fuel is subject to stringent performance overall process quality requirements in terms of purity and degree of size reduction.
Vecoplan has implemented a suitable plant with high output quality and maximum energy efficiency. The plant performance totally fulfils the requirements of Plevin’s customer to ensure compliance with all contractual obligations.
The requirements for the material
Input = Waste wood
- From an extremely wide range of sources and disposal areas
- Includes foreign objects (metal, non-metal)
Output = High-quality fuel wood chips
- Defined fuel wood chip size between 4 and 100 mm
- Free from metallic and non-metallic foreign objects
- With minimum proportion of fine material portion
- Complies with the fuel quality defined by Plevin
High-performance overall process
Completely from a single source
The entire plant was designed and implemented by Vecoplan as a complete provider. Intensive on-site support was ensured by contacts at the Vecoplan Ltd. at all times.
The scope of service:
- Consulting
- Project planning
- Delivery of machines
- Installation
- Commissioning
All Vecoplan components in the Plevin waste wood processing plant are harmonised with each other in the overall process and designed for performance, efficiency and output quality. With a capacity of up to 80 t/h, the plant in Hazlehead is one of the most powerful in Great Britain. The Vecoplan components include:
- Conveying components:
Trough belt conveyors VFB, Drag chain conveyors, Double screw conveyor, Truck loading station - Storing components:
Scraper floor bunker - Shredding components:
Re shredder - Separation components:
Overbelt magnetic separator VÜB, Disc screen, Sorting cabin/Handsortierung, Eddy current separators, Oscillating screens
High performance, high efficiency
Re shredder VNZ
- Special double-shaft re shredder for the re shredding of pre shredderd waste wood
- Adapted for re-shredding as well as single-stage shredding
- Minimising of fines production by slow speed rotors re shredding (only 160 rpm)
- It is also possible to feed the re shredder directly with unshredded material
- Inclusive HiTorc-Drive (reduces the power consumption by up to 40 %)
We are happy with the overall result on every level. What fascinates us is the combination of reliability and performance. Vecoplan implemented a very stable high-tech solution for us, which has paid off.
From the start, we were able to work with Vecoplan very closely, constructively and in search of the best possible solution. The work and input we provided ourselves were brought together seamlessly thanks to good project management.
As our solution provider, Vecoplan has designed and implemented an optimised and complete system for us down to the very last detail. The shredding concept is a complete success in terms of output quality, performance and efficiency. We are very happy with the Vecoplan RDF processing plant. The system has been continuously reliable. The Vecoplan Live Service offers the best support for all ser-vice and maintenance work.
The chipboard industry needs material that meets strict quality criteria. With the complete solution from Vecoplan, we can reprocess large quantities of wood waste at an excellent quality – fast, reliably and energy efficiently.
Right from the start, our new plant works trouble-free. We are very satisfied with the Vecoplan solutions.
Vecoplan developed individual solutions for fuel feeding and the processing according to customer request. The system runs continuously and generates green energy.
As Engineering Manager, I was convinced that the slow speed re-shredding offered by Vecoplan, was key to minimising fines production. Vecoplan's solution is also incredibly efficient, thanks to their HiTorc-Drive technology. The entire plant is fully automated and can exceed the specified 60 tph.
For us as system operators, it is important that the system runs ... and it runs.
For us, the protection of the environment as well as the reduction of CO₂ emissions are not just empty phrases but determining factors. Due to Vecoplans conveying system the entire transport route of bark and chips could be relocated in lofty heights above the buildings and streets of Södra – and had been executed to our complete satisfaction.
The launch of the TDS V20 from the Terex & Vecoplan partnership is revolutionising the mobile shredding industry. The Vecoplan VNZ 200 XL H chamber offers the unique combination of medium speed shafts, an accurate cutting action, sizing screens and tramp material protection. Our customers are benefiting from one pass production and minimal fines creation, reducing running costs and maximising profits.
The highest priority in this project was to ensure that the specific requirements were met and that the system had a very high level of availability with low power consumption.
Vecoplan projects are always new and always different. Each project brings new challenges, experiences and insights. That's what makes it so exciting.
Vecoplan is one of the most innovative companies in the industry. This requires the will to perform, creativity and personal commitment from the employees every day. My job is to motivate the team to achieve top performance together. Vecoplan offers the best conditions for this, a high degree of appreciation and the necessary freedom to make a difference.
20 % of Vecoplan employees have been with the company for 20 years or more. Add to that young junior staff and colleagues who join us from other companies, and you have a healthy and effective personnel structure with which we can achieve a lot.
Vecoplan operates internationally - this gives us at service unit the opportunity to travel to different countries and meet a wide variety of people.
Application engineers at Vecoplan have to understand customer requirements and convert them into technical solutions - an exciting and demanding task that I enjoy.
Oriented to customer's benefits
Only shortly before the contract was awarded Plevin asked Vecoplan about an overall solution for a high-performance, efficient waste wood processing plant with high output quality and minimum fines production. On the basis of leading recycling and shredding technology, a corresponding plant was designed, implemented quickly and placed in service. The result: All the requirements were met and surpassed.
- Compliance with the specified fuel requirements:
– Fuel wood chip size between 4 and 100 mm
– Minimum proportion of fine material
– Free of foreign objects - High energy efficiency of the entire plant
- Intensive consulting and support by Vecoplan
