Biomass is one of the renewable energy sources that could replace conventional carbonaceous fuels. The remains of timber industry or the agro-food sector are attractive sources of biomass taking into account environmental and economic aspects. Stones of fruits such as cherries, peaches or apricots can be converted into heat in the combustion processes. They can also be converted into liquid or gas...
The paper presents results of study of the pellets made of agricultural biomass. In the tests wheat straw was used and then ground raw materials were concentrated using two types of pelleting machines: with flat matrix and driven by compacting rollers as well as with ring matrix. The research methodology consisted of measurements of physicochemical properties of pellets, i.e. humidity after compaction,...
In connection with the depletion of fossil fuel resources and negative impact of their combustion products on the environment, there is a need to search for renewable energy sources. Biomass of plant origin that can be used e.g. for the production of solid biofuels in the form of briquettes or pellets is one such source. The article presents an analysis of qualitative characteristics of briquettes...
Currently the global practice is to collect branches that remain in orchards and vineyards after maintenance pruning sporadically, using specially designed conventional hay balers. The EuroPruning project implemented in the Industrial Institute of Agricultural Engineering (PIMR) in Poznań involved developing the construction of a new machine for compressing branches remaining in orchards and vineyards...
