Abstract
Plant biomass is one of the most effective renewable energy sources of a great potential in the energy field. In the form of fuel it ensures one-seventh of the total fuel resources in the world.
One of the greatest sources of biogenic fuels is the lignite-cellulosic agricultural waste. The bulk of this biomass is used as animal feed and manure on arable land.
The briquettes from tobacco stems have a huge market potential as fuel. The potential exists due to the presence of accessible unused raw materials of high energy density.
The increasing production of biomass briquettes consists in developing new technologies and advanced installations of a technological challenge – delivering the highest quality with minimal production costs.
The paper treats the possibilities for briquetting tobacco stems under the conditions of single production by farmers who meet their own heating needs. Two fundamentally different technological schemes of briquetting machine development are presented.
Key words: bio-energy, biomass, tobacco residues, briquette, briquetting machines
