As is known, the production of pellets and briquettes from wooden waste as well as from other types of biomass needs the raw material to be chipped first and then dried up 10…12% of moisture content. To do this different equipment can be used. In the XX century one of the most well-known complexes with this aim were drying drums and hammer chippers. But in the XXI century it became necessary to reach one more economic purpose – energy efficiency.
The production of pellets, briquettes, wood-polymer composites and porous ceramic bricks needs the raw materials to be dried and chipped first. Most of the drying equipments require an exterior heating source. In this article we will try to find out which heating equipment is better to be used in the named production process.
It is well known that briquetting is one of the best ways of turning wooden waste into ecobiofuel of high quality. Since the wastes have minimal and sometimes even negative worth and briquettes are sold at a price of at least 100 Euro per ton it is logical to conclude that producing briquettes can bring high profit. Is it really true?
