In any manufacturing process, the production of waste is unavoidable. But instead of disposing of the residue, you can turn it into valuable energy by using an industrial briquette machine. This will save you space as well as transport costs, and you will be able to provide your own fuel for your industrial boilers. And as a bonus, you will profit from it rather than having expenses for waste management.
At C.F. Nielsen, we have a specialized briquetting solution developed for torrefied wood, which can replace coal in power plants. To replace coal, our machines can produce briquettes in diameters from 50 mm to 90 mm. You will obtain the highest capacity when using our BP6510 briquetting press, which produces a briquette in either 75 or 90 mm diameter. In case smaller pieces are required at the power plants, the briquettes can be shipped in bulk and shredded or down-sized.
Our machines can briquette torrefied wood at moisture levels as low as 2 %, but preferably 4-6 %, while also achieving a high density, between 1,1-1,2, which is higher than the density of regular biomass briquettes. This results in a high energy value at a bulk density between 500 and 650 kg/m3.
At C.F. Nielsen, we have tested torrefied raw materials from many different production plants all over the world, as well as sold plants for testing and production. This has enabled us to develop a unique application for torrefied wood that can down-size the raw materials through our precompression and die system. Our machines can handle raw materials above 100C, and they have a considerably lower power consumption per tonne than any alternative on the market.
Regular coal is an expensive as well as a non-sustainable energy resource, but it is still frequently used in many power plants around the world. However, in most cases, it is possible to replace coal with torrefied wood briquettes, which is a sustainable and cost-effective solution with a lot of benefits compared to regular charcoal:
Perssons Träteknik AB is a traditional Swedish wood planning factory producing various wooden profiles for the Swedish market and exports. In 2007 Perssons Träteknik AB bought their first mechanical briquetting press from C.F. Nielsen. The press was
One of our customers in Sweden, Olle Dahl Såg, had 3 old W75 briquetting presses producing 75 mm industrial briquettes. The capacity of the 3 presses were approx. 700 kg/h per press. The presses were equipped with 55 kW main motors, resulting in a to
In Sweden the major part of briquettes are used for industrial briquettes for district heating plants. Over the years we have sold numerous plants in Sweden.
Torrefied wood is regarded as the new “coal”. Apart from having many similarities with coal, it is still renewable energy and believed it will replace many types of biomass within the years to come. The main advantage is that the densified torrefied
One of our French customers had a company producing different types of paper products – adhesive and non-adhesive. It was expensive to dispose of the waste, so he needed to find a solution.
One of our customers in Africa had invested in equipment for harvesting peat. The peat was dried in the sun, but they needed a solution to create a commercial fuel, which they could sell locally for power plants and domestic use.
Normally, money is not treated as a waste; however, for FNMT (Fábrica Nacional de Moneda y Timbre) in Spain, who among others produce bank notes, it is important to treat the waste very carefully.
One of our customers in the U.K. wanted to replace 4 old briquetting machines with new technology. The raw material is the waste from production of Insulation panels. The raw material is extremely light weighing at only 25-30 kg per m3.
