Abstract
Paper is focused on development of new patented construction of screw briquetting machine for compacting biomass into the solid biofuel. Developed machine design is based on achieved results of comprehensive research of the complicated process of biomass densification. Patented construction provides two main goals: the elimination of axial forces, which causes increasing of bearings lifetime, and a new modular design of pressing chamber and tools with geometry based on application of the mathematical model. Research of the biomass densification pointed to the need for modular design of densification machine, where it is possible to control all significant parameters of the densification process. The goal of this paper is to present a new patented design of screw press, which satisfies all requirements for modularity and control of the parameters. It allows optimizing this process for different types of raw materials and achieving high quality production. Results of experimental research of densification process then allow the engineering design of the production machine tailor-made to the customer, while being able to minimize investment, energy and operating costs. The developed design of screw press is unique in its modularity and high reliability.
Highlights
The recent situation in the world associated with the disruption of energy supply in world markets, the gas crisis, as well as the global financial and economic crisis, highlights the challenges posed by energy markets and highlights energy security issues
The use of biomass could be the answer to this question, but a more sophisticated solution is offered by the transformation of biomass waste into high-grade forms of solid biofuels with higher energy density, greater comfort of use, transport and handling
The aim of the paper is to point out the results of research of biomass compaction into the form of solid biofuels and their evaluation in the design of a new patented screw press design (Fig. 10)
Summary
The recent situation in the world associated with the disruption of energy supply in world markets, the gas crisis, as well as the global financial and economic crisis, highlights the challenges posed by energy markets and highlights energy security issues. The issue of energy security occupies an important place in the security of each state. It is important because only a reliable supply of energy creates the conditions for the harmonious development of the modern economy and society as a whole. The current geopolitical situation shows how important the diversification of energy sources is. It is the use of alternative energy sources that becomes the way out of this situation. At the time of the search for new energy sources in the world, the question of the possibilities and methods of efficient use of biomass as the most important renewable energy source arises. Biomass is the most promising renewable energy source with the most efficient storage options for this energy
