The aim of this study was to determine selected energy parameters, leachability heavy metals and phytotoxicity biomass ash for different types plant (wheat straw, miscanthus bark sawdust) poultry manure, as well biochars produced from them. Based on data proximate ultimate analysis the investigated materials, fuel value index (FVI) calculated their suitability production. ashes were analyzed both chemical composition leaching behavior. test aqueous extracts performed Lepidium sativum L. It...

The process of biomass compaction depends on many factors, related to material and process. One the most important is proper fragmentation raw material. In cases, more fragmented makes it easier achieve desired quality parameters pellets or briquettes. While chipping prefers moist materials, for grinding, needs be dried. As drying temperature changes properties material, these may affect grinding aim this work was determine influence in range 60–140 °C grindability. To only effect, without...

Miscanthus is resistant to dry, frosty winters in Poland and most European Union countries. gives higher yields compared native species. Farmers can produce pellets after drying it for their own heating purposes. From the third year, efficient plant development begins, resulting a yield of 25–30 tons dry matter from an area 1 hectare. Laboratory scale tests were carried out on processes drying, compacting, torrefaction this biomass type. The analysis process was conducted at three...

Increasing production of waste has compelled the development modern technologies for management. Certain fractions municipal solid wastes are not suitable recycling and must be utilised in other ways. Materials such as refuse-derived fuel (RDF) used cement or CHP (combined heat power) plants. The low bulk density leads to many problems pertaining transportation storage. In case biomass, these cause reduction pelletisation. This paper therefore presents a comprehensive study on RDF pellet...

The aim of the paper was to summarize and discuss current research trends in biomass thermal treatment (torrefaction process). Quantitative analyses were carried out, which main countries, units scientists indicated. analysis showed a clear upward trend number publications after 2010. Most on selected topics come from China, USA, Canada, South Korea, Republic Poland (Web od Science—Core Collection (WoS-CC) Scopus databases). also that most relevant WoS-CC categories summary are: Energy...

The paper presents the results of research aimed at evaluating possibility using selected tree leaf species to produce solid biofuels. production qualitative biofuels from urban leaves meets expectations municipal sector. Collection in areas is very often necessary for road safety reasons, need collect biomass rich dust and pollution as well infested with pests. allows effective management this raw material energy recovery. performed indicates such a possibility, obtained ash used soil...

The relevance of the study is confirmed by rapid development automation in agriculture, particular, horticulture; lack methodological developments to assess effectiveness introduction robotic technologies; and need expand functionality mobile robots. purpose was increase level autonomy a platform for picking apple fruits based on new method, develop system factors determine robots horticulture, control using integrated processing onboard data. article discussed efficiency systems...

This paper presents the results of work carried out by project "Development Methods for Pretreatment Agricultural Biomass Used Production Energy" supported national program Innovative Economy. The research includes analysis several factors related to utilization straw energy purposes. main points interest were a decrease ash-sintering potential using inorganic additives, application alloy steels in boiler construction, and leaching mineral compounds minimize corrosion risk. also provides...

For biomass compaction, it is important to determine all aspects of the process that will affect quality pellets and briquettes. The low bulk density leads many problems in transportation storage, necessitating use a compaction ensure solid at least 1000 kg·m−3 600 kg·m−3. These parameters should be achieved relatively pressure can through proper preparation raw material. As includes drying stage, aim this work influence temperature pine range 60–140 °C on process. To whether effect...

Abstract The paper presents the results of research, objective which was to determine impact particle size distribution and density digestates ash on tensile strength granular fertilizer obtained from mixtures these substrates. Particle distribution, absolute density, envelope porosity substrates were determined. Granular fertilizers made clean their mixtures. Envelope granulates within 0.81 - 1.88 g⋅cm -3 . determined compaction degree 3.65 10.12. While, index IS 0.5 0.55 lower in...

It is necessary to reduce dependency on fossil fuels for heating and waste generation, while also utilizing the energy potential of materials. One possibility create fuel pellets where makes up a small proportion so that properties wood are not significantly altered with. This article investigates usage containing spent coffee grounds (5 % or 10 %) face masks %), with spruce sawdust as primary input material (80 90 %). The elemental, thermogravimetric, calorific value, mechanical durability,...

Abstract Technology of processing agricultural raw material and production residues from agri-food industry often requires their dewatering. Digestate is one such materials i.e. the mass remaining after bio-gasification process, which has great hydration (above 85%). The objective research was to know impact dewatering on change water content in digestate biogas Piekoszów. A mechanical process carried out reflected conditions operation screw presses for plant materials, whose screen internal...

Paper presents design process of the prototype line, dedicated for production fertilizer pellets from digestate-ash mixture. For enrichment nutritional characteristics final product additives were also used, like urea, elemental sulphur or phosphorite, and special fungal strains Trichoderma spieces. During this raw material will be dried (raw digestated), mixed, granulated packed in one technological line. Presented concept, shows that there is possible to produce high quality fertilizer,...

Biogas production is an important component of sustainable energy management. In addition to energy-rich biogas, this process also generates solid waste in the form digestate. The management stream has been problematic for many years. One promising method utilizing fraction seems be incineration under controlled conditions. This paper presents analysis mixtures different digestates assess their suitability incineration. Four based on corn silage CS and apple pomace AP were used as test fuel....

The development of civilization, population growth and technological cause an increasing energy demand.Solid biofuels have particular importance in the sector.The enormous potential biomass Poland is agriculture with related possibilities setting up fast growing plantations, which attracted attention growers for past years.One most important phenomena occurring processes mechanical processing phenomenon friction.The purpose work was to determine coefficient external friction (static kinetic)...
