Many biomass by-products, such as dust and smaller particles including many types of agricultural raw materials cannot be used in a gasifier. However, by processing the raw material into high density briquettes, it is possible to use the raw material as valuable fuel.
Most gasifiers require homogenous fuel as raw material with the correct amount of moisture and within a specific size. Many types of raw materials such as sawdust, other dust types, and smaller pieces of biomass are thus not suited for gasifiers, either because of their size or humidity level. However, turning this type of waste either from wood or agricultural waste into briquettes makes it possible to meet all requirements. Furthermore, it can add considerable value to the raw material, converting by-products into briquettes.
Our briquetting presses combined with other types of equipment like shredders, hammer mills, and drying systems can handle all types of dry and wet wood, as well as agricultural-based raw material, and turn it into high density briquettes for gasification.
Gasifiers require briquettes with high density, otherwise the fuel will disintegrate in the densifier. Our briquetting presses are able to produce high density briquettes out of most types of raw material due to our front-line technology.
The briquetting lines can produce industrial briquettes with diameters ranging from 50mm to 90mm, in different lengths from 20mm up to 100mm, and with densities between 1,1 and 1,2, making it the ideal fuel for gasifiers.
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.
