BRUNEROVÁ, A. – ROUBÍK, H. Podtyp: Příspěvek ve sborníku (mimo kategorie RIV); Manual low-pressure briquetting press and its use in rural areas of North Sumatra. 2016, The existing burden on biomass resources, negative impacts on environment and problems of energy lowering resources could be alleviated by undertaking comprehensive alternative energy technologies for decentralized application. Utilization of biomass for combustion purposes ensures energy consumption requirements for heating and cooking in developing countries (DCs). However, using of raw biomass is characterized by low energetic efficiency and harmful air pollution, but densification technology (briquetting) can effectively reduce mentioned undesirable impacts. However, implementation of briquetting technology in DCs encountered limitations related to background facilities; heavy machinery as high-pressure briquetting press is used for briquette production, which means high initial expenditures and energy consumption. Therefore, manual low-pressure briquetting technology (operation pressure <5 MPa) represents alternative for biomass densification in DCs. In present research a manual low-pressure briquetting press was constructed and tested in rural areas of North Sumatra. Partially disassembled construction was manufactured from wood components. System of piston and single lever powered by man power was used for biomass compaction; with square shaped briquettes. Feedstock materials originated from local production, i.e. plantation trees (coffee, cacao, coconut, oil palm), rice, sawdust, fruit skins, water plants or bamboo. Materials were crushed and mixed with water and binding agent (waste paper) in different ratios (biomass:paper – 1:1, 2:1, 5:1). After the feedstock compaction the briquettes were sundried. The results exhibited that amount and type of binding agents are major factors influencing briquettes quality, thus, low-pressure press efficiency. It was also proved that present design can be useful for small briquette manufacturers in rural areas..
