Loading And Unloading

The constant development of the country's agricultural sector allows the production of biofuels, such as fuel pellets, from agricultural waste - straw, corn and sunflower husks. However, the transportation of fuel pellets is quite energy consuming. The process of loading and unloading, transportation over long distances requires complex mechanized equipment. The use of a pneumatic conveyor for grain reloading will allow to provide high-quality transportation of fuel pellets. The aim of the article was to investigate the operation of the pneumatic conveyor for overloading fuel pellets, to determine the optimal indicators that affect the productivity of the pneumatic conveyor. Since fuel pellets, as raw materials, are structurally similar to cereals, a study of the pneumatic grain conveyor PTZ-25 was conducted. The dependence of the productivity of the pneumatic conveyor on the lifting height h, m and the length of the pipelines L, m was obtained. The obtained results showed that by reducing the length of the pipelines by four times and the lifting height by half, the productivity of the pneumatic conveyor will increase by 1.15 times. Key words: fuel pellets, pneumatic conveyor, productivity

The article contains consolidated results of the simulation of the untreated fuel raw materials use scheme in comparison with the fuel pellets production. Specific indicators and the main factors of influence on energy, ecological and economic efficiency of biofuel use are determined. It was found that the organizational scheme of sunflower husk pelleting and pellets transportation on up to 400 km distance is a more energy-efficient solution. In this case, the main energy costs will be related specifically to the pellets production, and therefore the main direction of energy costs reduction should be the production energy efficiency increasing – electricity consumption lowering. Otherwise, in case of fuel transportation on more than 400 km distance, the main attention should be paid to the motor fuels consumption lowering and the transport load optimization. The pellets production and transportation leads to an increase in total greenhouse gas emissions compared with husk transportation on up to 2000 km distance. Therefore, husk pellets production for domestic transportation is not an effective solution from an environmental point of view. The husk transportation is economically more efficient compared to the organizational scheme of pellets production and transportation on up to 300 km distances. Financially economic efficiency is the main limiting factor at decision-making on the organizational scheme of sunflower husk use.

Substitu Tion

Under contemporary socio-economic conditions, requirements for housing and utility infrastructure are increasingly stringent. In this context, the selection of energy sources for heating supply systems tends towards options combining maximum efficiency with environmental friendliness. In this context, the substitu-tion of traditional heating fuels (natural gas and oil) with firewood has the potential to contribute to the future fuel and energy balance in the Russian regions. The application of wood fuel in the energy sector provides for the utilisation of wood and plant waste while reducing pollutant emissions into the atmosphere. For an objective assessment of increasing the degree of environmental safety, a complex index reflects the level of reduced environmental impact, in particular, on atmospheric air. In the present work, a calculation of reduced environmental impact under the conditions of transferring the heating supply system of the Listvyanka village to wood fuel (pellets)is presented. The calculation results demonstrate the total prevented environmental and economic impact to amount to 3 147 550 roubles (in 2020 prices.

The comprehensive study of the process of thermal decomposition of fuel pellets from Heracleum Sosnowskyi biomass was carried out. Kinetic parameters of the process were determined based on thermo-gravimetric analysis in comparison with a sample of wood pellets from coniferous wood. The biomass of heracleum Sosnowskyi was collected in the village of Vylgort, Komi Republic, dried to atmospheric-dry state, ground to mean diameter dm<0.25 mm. The elemental composition, the content of the main components, the value of the thermal effect of the initial plant raw materials are determined. The features of the thermal decomposition of samples are established. Kinetic studies of samples pressed at 10 kN were carried out in air environment at heating rate of 5, 10 and 15 °C/min in the temperature range from 25 to 1000 °C using differential methods of Friedman and Ozawa-Flyn-Wall. Comparative analysis of softwood pellets and fuel pellets of hogweed Sosnowskyi confirmed the possibility of using the latter as an independent energy fuel, and as an additive to pellets without significantly reducing their quality characteristics. The results of the presented studies can be used to develop technology and equipment for burning fuel pellets for the purpose of rational extraction of thermal energy. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Wood fuel is the principal source of energy in Kenya and contributes to more than 17% of the global deforestation. Saving on the amount of charcoal used at home will not only help save on cost that can be used to offset the economic burden caused by the impacts of COVID-19 pandemic but also control deforestation. This will foster the realization of more than10% tree cover in Kenya by 2022 as per the presidential directive of 2019, Kenya Vision 2030 and the Constitution of Kenya 2010. This study aimed at promoting this goal by encouraging adoption of charcoal briquettes made from clay soil as a binder, charcoal dust and charcoal pellets as raw materials and ignited by pure charcoal (PC) to produce energy to form Clay Charcoal Blend Briquettes (CCBB). The study compared the amount of energy consumed by a household of five people using CCBB and PC. The results were: adoption of CCBB reduced the amount of charcoal used by 1.025kg per day, 21.325kg per week, 92.25kg per month and 1,122.375kg per year. This would save hundreds of trees from destruction. Additionally, using CCBB saved a household Ksh.45 (0.41USD) a day, Ksh. 945 (8.59 USD) a week, Ksh. 4,050 (36.82 USD) a month and Ksh. 49,275 (447.95 USD) a year as compared to using PC. The study therefore encouraged for adoption of CCBB concept.

Renewable reed biomass has traditionally been used for various purposes. Currently, an energy-dependent society is returning to the use of natural energy sources. The paper is devoted to the study of reed reserves in the Lower Volga region, production technology, and quality assessment of pellets from it. Reed mowing with further production of fuel pellets from biomass will not only provide the local population or small enterprises with energy but also solve a number of environmental problems. The main environmental problem is the high fire hazard of reed beds. The main characteristics of the pellets that have been investigated by the authors are humidity, ash content, calorific value, and the composition of the ash residue. When granulating shredded cormophytic biomass, the main process parameter affecting the fuel pellet quality is the moisture content of the raw materials, which has been determined experimentally. To improve the consumer properties of the granules, binders were also experimentally selected. Binders should not reduce the calorific value and impair the composition of the ash residue

Bananas sale or pisang sale  is a popular traditional food in Aceh  and its production  mostly comes from the area of northern Aceh and east Aceh. Traditional banana processing process is using fumigation method by wood fuel and coconut shell. Traditional banana sale is dark brown and tastes is less good. The banana processing process here uses a heating cabinet with a heating method and with an average temperature of 90-70 ° C for 14 hours. The purpose of the study was to obtain the optimal temperature used in the processing of banana sale in order to know the quality and good quality of on the traditional way. The preheating process with high temperature is to accelerate the decrease in water content in bananas so that the drying process becomes faster. The quality of banana sale is produced with a reddish color and very sweet because of glucose in the banana. The cooking process is by using LPG gas. The benefits of using LPG gas are because it is environmentally friendly, does not cause air pollution and the result of LPG combustion does not leave the smell, so it is suitable for use as fuel or raw materials for industry

The need to increase the use of renewable biomasses for energy supply, such as fuel pellets is significant. However, different types of biomasses have different mechanical properties to be pelletized, which entails a limitation in available raw materials for pellet producers. Within this study eleven different pure substances from biomasses were separately mixed with European beech and Scots pine, to identify its impact on the densification process. Beech and pine pellets were used as control materials against their corresponding pellets mixed with substances representing: cellulose, hemicelluloses, other polysaccharides, lignin, protein, and extractives. The mechanical properties were investigated as well as FT-IR and SEM analyses on the pellets. The results showed that the addition of the substances xylan and galactan created the hardest pellets for both pine and beech and that adding extractives to wood affects pine more than beech in relation to hardness. The FT-IR data could not provide clear explanations as to the variation in hardness and springback behavior through the identification of major functional groups in each pellet. It can be concluded that biomass residues rich in xylan and galactan increase pellet quality in terms of strength and durability without affecting the production process.
